9 Mechanical Installation 4. Installation 4.1 Before you start The geared motor must only be installed if the details on the nameplate of the geared motor match the permissible EX application area on site (equipment group, category, zone, temperature class, maximum surface temperature the geared motor is undamaged it has been ensured that there are no atmospheres, oils, acids, gases, vapours or radiation that may cause an explosion present during installation 4.2 Preliminary work Drive shafts and flange surfaces must be thoroughly cleaned of anticorrosives, contamination etc. (using commercially available solvents). Do not permit solvents to penetrate to the bearing seals - they will be damaged! 4.3 Installation instructions Installation the gear motor only in the mounting position specified on the nameplate of the gearbox. Angle variations admitted between ±5 respect to the horizontal axis. Please use only attachment elements of the required sizes Use only the existing attachment holes in order to fix the device in place The fixing to the machine must be secure and without vibrations; the structure must not be torsionally stressed. Handle all rotating parts with particular care Only driven elements with ATEX approval may be used. Under no circumstances should you force pulleys, couplings, pinions etc. onto the end of the shaft by hitting them with a hammer (damage to bearings, housing and shaft!) Unscrew the cap or disc facing the end of the shaft, so that the centred shaft end is exposed. The shaft can be supported under a press and in that way the pulley or coupling can be pulled onto the shaft. A puller device is required for disassembly When pulleys are used please ensure that the tension in the belt is correct (according to manufacturer's specification). Only belts with adequate electrical resistance < 10 9 Ω must be used. If the motor shaft is directly connected to the component to be driven without a coupling, you must ensure that that radial offset (centrifugal errors) and any effect of axial forces (tension or pressure) are excluded. Under no circumstances should you exceed the permissible radial and axial forces on the shaft (s. Chapter 3.2) Operating instructions for compressed-air worm geared motors 9

10 Mechanical Installation You will simplify assembly if you first lubricate or briefly warm the drive element (to C). Drive elements such as pulleys, couplings etc. must be covered by a guard. 4.4 Installation in an environment where there is a risk of explosion Ambient temperature Temperature class / Surface temperature Protection category Ambient conditions Power output and torque Braking operation When installing the geared motor in an environment where there is a risk of explosion, please ensure that you follow the safety instruction in chapter 2.2! The geared motors that are protected against explosion meet the design regulations of equipment group II, category 2GD (EX atmosphere gas and dust). They are intended for use in zones 1/21 and 2/22 Geared motors in category II2GD must only be used at temperatures between +1 C and +40 C. In the case of ambient temperatures that do not comply, you must contact SPECKEN-DRUMAG! Geared motors in category II2GD (EX atmosphere gas and dust) are approved for temperature class T4. This corresponds to a maximum surface temperature of 135 C. All geared motors comply with protection category IP54 in accordance with EN You must ensure that the geared motors are adequately ventilated and there is no external influx of heat (e.g. via couplings). Adherence to output torque and the permissible transverse and axial forces must be assured. The geared motors must not be used for braking in the EX area. Braking operation is an operating state in which the motor is driven by an externally applied torque in the opposite direction to the one prescribed for air input. 10 Operating instructions for compressed-air worm geared motors

11 Mechanical Installation 4.5 Pneumatic Installation For lengths of less than two metres between the main supply pipe and the machine you should use connecting pipes of the nominal diameter of the connector to the machine, and for lengths over two metres, pipes that are one size larger than the nominal diameter. In the case of applications with one direction of rotation, a silencer should be fitted to the air outlet. This is part of the equipment supplied. In the case of a reversible machine that can be operated in both directions, a fourway valve can be used. In this case the valve is connected to both connectors on the machine, and the silencer is fitted to the air outlet or valve connector. Remove the plastic covers from the connectors. Keep the covers in a safe place in case you want to decommission the machine at a later date and put it into storage (see also "Decommissioning and Storage") Set the air input to "Off". Do not use a jubilee clip to seal the threaded pipe connection. The air feed to the motor must be filtered. We recommend a filter grade of 5 microns. The maintenance unit, the directional control valve and the volume controller must be selected according to the air consumption of the motor, and not according to the size of the connections to the motor. Calculate the pipe cross-sections so that the pressure loss between the maintenance unit and the motor is less than 0.5 bar. The compressed-air motors must be lubricated. Exception: Non-lubricated motors NL... Fill the oil reservoir of the lubricator to the prescribed oil level. As a lubricant you should use acid-free, easily atomisable proprietary oils with a viscosity of 200 mm 2 /s. Before you connect the compressed air connector to the machine you should first clean out the pipe by blowing air through it at low pressure, in order to remove any particles of dirt from the pipe. When doing so you must wear safety glasses and not get in the way of the jet of air. 4.6 Adjustments Filtration and lubrication Lubricator adjustment Speed control A filter, controller and lubricator (not supplied) of a suitable size are to be fitted to the compressed air pipe at a distance of 1-2 metres from the machine. Adjust the lubricator so that one drop of oil is delivered for every m 3 of air throughput. No adjustments are possible to the machine. (not for Non-lubricated motors NL ) If the speed is to be controlled, a valve must be included to control the flow of air (pressure regulator, ball valve etc.) Operating instructions for compressed-air worm geared motors 11

12 Commissioning 5. Commissioning 5.1 Commissioning Before commissioning the geared motor you should ensure that all the components that carry air are correctly connected. Do not loiter in the immediate vicinity of the stream of compressed air. Set the air input to "ON". Adjust the pressure or the flow as necessary to achieve the required speed or the required torque. Adjust the lubricator as described in chapter 4.6. (Exception: Non-lubricated motors NL ) Check the oil level once a day and top up with oil if necessary. (Exception: Non-lubricated motors NL...) 5.2 Measuring the surface temperature (only when used in the EX area) Measuring surface temperature The details of maximum surface temperature on the nameplate are based on measurements taken under normal ambient and installation conditions. Even minimal changes to these conditions (such as confined installation conditions) may have a significant influence on temperature. When the geared motor is being commissioned it is essential to carry out a measurement of the surface temperature under maximum load. This measurement can be carried out using commercially available temperature measuring equipment. The surface temperature is to be measured on the flange cover, item 8, of the gearbox (see chapter 1.3). Maximum temperature is reached after approx. 2 hours, and must not exceed 100 C. If the surface temperature is higher than that, the geared motor must be stopped immediately. In this event you must contact SPECKEN DRUMAG. 12 Operating instructions for compressed-air worm geared motors

13 Maintenance and Repair 6. Maintenance and Repair 6.1 Maintenance Lifetime lubrication Loss of power With adequate lubrication the compressed-air motor (exception: Non-lubricated motors NL...) operates practically maintenance-free. The gearbox is lubricated for life. The gearbox should be checked for noises and/or increased play in the bearings at regular intervals. Clean the filters in the maintenance unit regularly when in operation, and empty any condensation. Check the oil level in the lubricator at regular intervals and top up if necessary. If the motor is not running perfectly after being in operation for a longer period, this is usually attributable to resinous oil residues that are impeding the free movement of the blades in the rotor slots. In this case it is appropriate to rinse out the motor with paraffin. Release all pressure from the motor. Unscrew both pipes or the silencer from the motor and pour a few drops of paraffin into the inlet, then turn the shaft by hand for a few minutes in both directions. Repeat this process, then connect the air pipe, and at low pressure (approx. 0.5 bar) and low speed, start up the motor. Protect your face and eyes! Cleaning the silencer Dust coating Oil level Gear seals Oil change Dismantle the silencer and clean the felt filter. When air emerges that is free of paraffin mist, lubricate the motor with 3 or 4 drops of oil. Check also the maintenance unit. If the motor is still not delivering full power you should repeat the process, or it may be due for overhaul. It is necessary to verify that there isn t any dust coating thicker than 5mm on the gear motor. Remove dust periodically. Verify the correct oil quantity through the oil level plug, if present. Gears without oil level plug are lubricated for life. Each 1000 hours verify the good condition of oil seals, gaskets, if necessary replace the oil seals. After hours, replace the oil, obviously this limit can be different depending on the type of service. This operation is not necessary for units supplied lubricated for life. Operating instructions for compressed-air worm geared motors 13

14 Maintenance and Repair 6.2 Repair Vane wear Gearbox service With regular maintenance the wear to moving parts is minimal. Lubricated motors: It is only necessary to replace the vanes and ball bearings in the motor after between 5,000 and 8,000 hours in operation. This also depends on the speed at which the motor is run, the air pressure and lubrication. Non-lubricated motors: It is necessary to replace the vanes after between 2,500 and 5,000 hours in operation. This also depends on the speed at which the motor is run, the air pressure and quality of air (purity, humidity). If you intend to carry out the repair yourself, order a repair kit for the motor. It contains all the parts that can be replaced. We recommend that you should send in the motors for repair to our factory. We have all the necessary tools for disassembly, all the original spare parts and the experts to set the motor with all the correct clearances following the repair. Performance, efficiency and service life all depend crucially on the clearances. In normal circumstances do not remove the gear casing closing cover for any reason. In the case of planned maintenance, only by a qualified person, it is possible to disassemble the gearbox ensuring the casing has first reached normal ambient temperature and ensuring no foreign bodies are allowed into the inside of the box and when reassembled the unit is tested to ensure to original specification. 14 Operating instructions for compressed-air worm geared motors

15 Maintenance and Repair 6.3 Decommissioning and Storage Switch the compressed air feed to "OFF". Release all pressure from the motor. Disconnect the motor from the compressed air pipe. Disconnect the geared motor from the machine to which it is fitted. Remove the silencer element. Blow clean, dry air at low pressure into the inlet of the machine. Pour a few drops of oil into the inlet and turn the shaft by hand to distribute the oil. Fit the plastic covers to the connectors. The machine can now be stored until it is next used. 6.4 Faults on the geared motor Fault Cause Remedial action Torque too low Speed too low Motor will not run Motor becomes hot Motor runs, becoming slower in operation Dirt or foreign bodies Corrosion inside the motor Faulty mating Air pressure too low Hose diameter to small Restricted exhaust Internal components seized Compressor too small / inadequate air supply Check and clean Check and clean Refit the motor Increase pressure Fit bigger hoses Check and repair Dismantle and repair Provide greater volume of air Air supply too far away from the motor Optimise installation Operating instructions for compressed-air worm geared motors 15

18 Warehouse storage When moving the unit, care should be taken to protect external parts from breakage or damage due to accidental knocks or falls. If the unit is to be stored in a hostile atmosphere or for a long period of time (2/4 months), it is important to apply protective and waterproofing products to avoid deterioration of shafts and rubber parts. Before starting up the unit, carry out the following checks: Check the data shown on the name plate of the reduction unit and/or the electric motor; Check for any leaks of lubricant If possible, remove any traces of dirt from the shaft and from the areas around the oil seal. If the oil seal is not immersed in the lubricant inside the assembly during particularly long storage periods (4/6 months) it is recommended that it should be replaced as the rubber might stick to the shaft or even have lost the elasticity it needs to work. Installation Example of a pulley mounted correctly on the slow shaft of a reduction unit Installation Particular care must be taken when installing drives, as this is often the source of damage and down time. Careful choice of the type of drive and mounting position can often avoid the need for protection of sensitive areas, particularly underneath the unit from oil leaks, however limited they may be. - The machine must be firmly fastened in place in order to prevent any vibrations. - Whenever possible, protect the reduction unit from direct sunlight and bad weather, especially when it is mounted on its vertical axis. - Make sure the air intake on the fan side is unobstructed in order to ensure that the motor is correctly cooled. - In the case of temperatures of < -5 C or > +40 C, contact Technical Assistance. - If the motor is to be started very often under load, the use of a heat probe inserted into the motor is recommended. - The various machine members (pulleys, gear wheels, couplings, etc.) must be mounted on the shafts using special threaded holes or other systems that ensure correct operation without risk of causing damage to the bearings or the external parts of the assemblies (fig.1). - Lubricate the surfaces that come into contact in order to prevent oxidation or seizure. Fig. 1 Correct and incorrect examples of pulleys mounted on the main shaft of a reduction unit. Fig. 2 A B 17

19 Installation Correct and incorrect examples of coupling connections Fig. 3 Starting up The unit should be started up gradually: do not immediately apply the maximum load the machine is able to take ; look for and correct any malfunction that may be caused by incorrect mounting. Running-in is not essential for the reduction unit to run properly since modern construction techniques for the gears and castings, the extreme cleanliness of the internal parts, and the excellent qualities of the lubricants used, ensure that the internal parts receive a high degree of protection even during the first moments. Servicing (A) (B) The pulley must be mounted on the main shaft as close as possible to the shoulder so that is does not cause excessive radial load on the bearings (fig. 2).Great care must be taken when connecting the couplings to ensure that they are well aligned, so as not to cause excessive radial load on the bearings (fig.3).when it is applied, paint must never be used on rubber parts: oil seal, etc. It must never be applied to any breather holes in plugs if they are mounted on the unit.in the case of assemblies with oil plugs, remove the closed cap used for transport and fit it with the breather plug that is supplied with the reduction unit.when the assembly is supplied without a motor, the following precautions must be followed in order to ensure that connections are properly made Mounting the motor on the pam B5/B14 flange Check that the tolerance of the motor shaft and the motor flange comply with at least one normal class of quality. Carefully clean off any trace of dirt or paint from the shaft, the centering diameter and the face of the flange. Carry out mounting operations making sure not to use force. If this is not possible, check the tolerance of the motor key and ensure that it is correctly fitted. Apply assembly grease to the shaft in order to prevent oxidation or seizure caused by contact. Good quality motors should be used in order to ensure that the unit works correctly, without vibrations or noise. Before mounting the unit on the machine, check that the principal shaft of the reduction unit rotates in the right direction. Use the oil window, if present, to check that the lubricant reaches the correct level required for the mounting position used. (C) The high degree of finish of the internal parts ensures that the unit will work correctly with only a minimum amount of servicing Generally speaking, the following rules should be followed: periodically check that the exterior of the assembly is clean, especially in the cooling areas; periodically check to see if there are any leaks, especially in the areas around the oil seals. Assemblies that are lubricated for life and thus do not have any oil plugs do not require any special maintenance except as stated above. For other assemblies, low maintenance is required with an oil change at 8/10,000 hours of use. The change of oil naturally depends on the type of environment and use to which the unit is put. Apart from the normal maintenance rules given above, make sure the breather hole in the plug is clean and, using the oil window, periodically check that there is sufficient lubricant. Should it be necessary to top up with lubricant, use the same type that is already in the reducer or one that is compatible with it. In case of doubtful incompatibility between lubricants, we recommend you empty out the oil from the gearbox completely and, before refilling with new oil, wash out the unit to remove any residue. When changing the oil, follow the previous instructions. Troubleshooting If any problems should arise when starting the unit or during its first few hours of operation, contact the after sales service unit of Motovario. The table shows a series of problems with a description of possible remedies. It should be kept in mind however that the information given is for reference only, as all the drives manufactured by Motovario are thoroughly tested and checked before they leave the factory. Please note that tampering with the assembly without prior authorization from Motovario immediately invalidates the warranty and often makes it impossible to ascertain the causes of a defect or malfunction. 18

21 Critical applications The performance given in the catalogue correspond to mounting position B3 or similar, ie. when the first stage is not entirely immersed in oil. For other mounting positions and/or particular input speeds, refer to the tables below that highlight different critical situations for each size of reduction unit. It is also necessary to take due consideration of and carefully assess the following applications by calling our Technical Service. - As a speed increasing. - Use in services that could be hazardous for people if the reduction unit fails. - Applications with especially high inertia. - Use as a lifting winch. - Applications with high dynamic strain on the case of the reduction unit. - In places with T under -5 C or over 40 C. - Use in chemically aggressive environments. - Use in a salty environment. - Mounting positions not envisaged in the catalogue. - Use in radioactive environment. - Use in environments with pressures other than atmospheric pressure - Avoid applications where even partial immersion of the reduction unit is required.

Lubrication (NMRV - MCV - NRV) Size gear reducers come pre-filled with IP TELIUM VSF, a synthetic gear oil suitable for permanent lubrication. They can be mounted in any position. Only sizes 075 and 090 should not be installed in mounting positions V5 and V6 without prior consultation with our Technical Advise Service to determine optimal lubrication conditions. Size 110 and 130 gear reducers come pre-filled with IP MELLANA OIL 220, a mineral based gear oil. Always specify mounting position if different from B3 when ordering size 110 and 130 gear reducers. Size 110 and 130 gear reducers have oil filler, drain, and level plugs. After installation, replace the closed cap fitted for transport with the breather plug prior to operating the unit. The synthetic oil used by MOTOVARIO can operate in all ambient temperatures between - 25 C and +50 C.
