6 General safety information and instructions Edition General safety information and instructions Helical geared motors comprise a gearbox flanged to a 1FU8 synchronous motor. The characteristics of the synchronous motor are described in Instruction Manual Correct use The gearboxes are permitted for all applications involving traversing, hoisting and rotary motion in industrial environments. It is extremely important to observe the application conditions when using these drives (e.g. degree of protection, ambient temperature, installation altitude...). Inadmissible activities, obvious incorrect use Under certain conditions, it is inadmissible to operate helical geared motors, because this can result in erroneous functions, equipment faults or even danger to human life, for example, Aggressive air, containing acids, as cooling medium Operation outside the normal air pressure. The motors have to be de-rated if they are operated outside the normal air pressure specifications. Operation with a high air humidity or in the presence of spray water. It is forbidden to use these geared motors in hazardous zones unless it has been expressly confirmed that this is permissible. Safety equipment may neither be disabled nor modified or used differently than the way specified. Warning Warning against hazardous voltages! The geared motors are connected to the line supply voltage or to AC drive inverters/converters. Severe bodily injury or even death can occur if live components are touched. The motors have permanent magnet rotors with a high magnetic flux density and a strong force of attraction to ferro-magnetic bodies. Voltage is present at the motor terminals when the rotor spins! Danger Personnel with heart pacemakers are in danger when they come close to a disassembled rotor. Caution Data, saved on electronic data mediums can be destroyed. Correct use means that all of the information and instructions in this Instruction Manual as well as the Instruction Manuals of the mounted components according to Section 7(e.g. spring-operated brake, mounted AC drive inverter...) which are mounted to form a drive unit, are carefully observed. ❶ 6 Helical Gearbox D Instruction Manual

7 Edition Product information 2 Product information 2.1 Product description DEMAG manufactures the helical gearbox D for SIEMENS. DEMAG mounts the 1FU8 permanent-magnet synchronous motors to the gearbox and the unit is then checked and tested. The helical gearboxes, used here, are essentially identical to the gearboxes as described in Catalog M15. However, instead of 1LA7 squirrel-cage induction motors, SIEMOSYN 1FU8 permanent-magnet synchronous motors are used. For helical gearboxes D with 1FU8, there is no clear assignment between the gearbox and a particular motor. This means that there is no MRPD (Machine Readable Product Designation) for these helical geared motors. The geared motor must be engineered on an application-for-application basis (selecting the helical gearbox D, 1FU8 motors etc.). Contact partner: - your local SIEMENS office The 1FU8 synchronous motor directly drives the gearbox. This means that the motor and gearbox are flanged together. The series of helical gearboxes includes 9 gearbox sizes which can be flanged to motors having different sizes. The gearbox sizes D1 to D4 have a casing manufactured out of high quality die cast metal or chill casting, which guarantees a high degree of stability with a high power density and low intrinsic weight. Gearboxes, Sizes D5 to D9 have a gray cast iron casing. Depending on the gearbox ratio, the gearboxes are either 2-stage or 3-stage gearboxes by flanging on an additional stage. The geared motor can be optionally equipped with an integrated AC drive inverter Micromaster/Combimaster 411 (6SE64). The gearbox, motor, mounted AC drive inverter components have their own rating plates; the Instruction Manuals for the mounted components are provided when the equipment is shipped. 2.2 Scope of supply As soon as you have received your geared motor, check that the equipment which has been supplied corresponds to the associated paperwork. The helical geared motors comprise a gearbox D and a 1FU8 synchronous motor. They can also be shipped with an integrated AC drive inverter, Micromaster/Combimaster 411 (6SE64). Siemens does not accept any warranty claims for defects which are subsequently notified. Helical Gearbox D Instruction Manual 7

Machine sets may not be hoisted by simply attaching the suspension equipment to individual machines! Observe the load capacity of the hoisting equipment used. 4.2 Storage The gearboxes must be stored as follows: In dry rooms with low temperature fluctuations. In the position in which they will be used. Protected against dust and moisture. Helical Gearbox D Instruction Manual 11

12 4 Installation, mounting Edition On a wooden surface. Vibration-free (no shocks/jolts). It is not permissible to stack gearboxes one on top of the other. Note If not otherwise contractually agreed, there is a 6 month warranty for gearboxes which are conserved as standard. The warranty starts on the day that the equipment is shipped. Caution! Otherwise the gearboxes could be damaged! For longer storage times, it may be necessary to take additional measures for the 1FU8 synchronous motor. It may be necessary to check the insulation resistance of the winding. 4.3 Installing the helical geared motor Caution! Never use compressed air to clean the drives The standard drive is suitable for use under normal industrial conditions. If the ambient temperature, atmosphere or air humidity deviates from these conditions, then only special versions of the helical gearbox may be used (refer to the rating plate). Ambient temperature: From 10 C to +40 C Installation altitude: Up to 1000 m above sea level The helical gearbox should be mounted as follows The circulating air to dissipate the heat must be able to flow over the equipment without any restrictions and the hot air may not be immediately drawn-in again. No chippings of the production material may be allowed to accumulate on the helical geared motor, fall between the out-drive elements or damage the sealing ring. The oil filling and oil drain holes as well as the rating plate must be accessible. Before the unit is mounted, it must be carefully checked as to whether the helical geared motor will be operated in the mounting position as stamped on the rating plate. The amount of lubricating medium depends on the mounting position. We recommend a canopy for types of construction with air entry from the top. For air entry from the bottom, a cover must be provided at the mounting location which prevents foreign bodies dropping into the fan. Gearbox sizes, D1 D5: These gearbox sizes are not vented. If, deviating from the series units, the gearbox vent (valve) is at the side, the oil filling plug at the highest point on the gearbox is replaced by the vent valve.

21 Edition Commissioning 5 Commissioning 5.1 Prerequisites The transport company must be immediately notified if any damage is identified when the equipment is received; it may be necessary to stop any commissioning work. Only commission the geared motors, if: You have read all of the relevant Instruction Manuals (gearbox, motor...) and the operating company has given you detailed instructions. The Instruction Manuals must be available at the installation location. You are qualified and have been suitably trained. You are not under the influence of drugs, alcohol or medication which could have a negative impact on your reaction or the way you work The general accident prevention, operating and installation regulations have been taken into account (e.g. DIN-VDE 0100/0113). Before commissioning, ensure the following Heat can be easily dissipated (e.g. the cooling slots are free) It is absolutely guaranteed that the drive unit doesn't represent potential danger (e.g. there is no danger as a result of rotating parts or components under voltage). The gearbox is correctly mounted and the drive elements secured. There are no other sources of potential danger. All electrical connections of the motor have been correctly implemented and the plug connectors are tight and cannot become loose. All motor protective devices are active. The drive can rotate freely. If the drive is to be tested without drive-out element, the key, if available, is secured so that it cannot fly out. Helical Gearbox D Instruction Manual 21

22 5 Commissioning Edition Checks during commissioning Please ensure, that: The helical geared motor runs perfectly (e.g. no speed fluctuations, no significant noise). There are no oil leaks. There is no significant vibration. ❶ 22 Helical Gearbox D Instruction Manual

23 Edition Service and maintenance 6 Service and maintenance Only carry-out service and installation work if: You are trained and knowledgeable in this particular area. The motors are disconnected from the power source and are not rotating. There is no danger (e.g. danger of crushing, slipping etc.). The motors are locked-out so that they cannot be powered-up again (circuitbreaker/main switch in the off position and locked-out). All cables, motor terminals are in a no-voltage condition (use a voltmeter to determine this). Always work with insulated tools. Always use the original manufacturer's spare parts. 6.1 Checking before starting work and during work When defects or damage occur, it is not permissible that the helical geared motor is commissioned and it must be immediately shut down! It may only be commissioned after the fault has been removed. Checking the helical geared motor Type of check: Measure: External damage Inform the person responsible Oil leak Inform the person responsible Unusual noise when operational Inform the person responsible Accumulated dirt Remove the accumulated dirt 6.2 Gearboxes/oil lubrication The gearboxes are filled with lubricant in the plant. The quantity of oil depends on the type of construction and the mounting position of the helical geared motor. This is stamped on the rating plate. Standard lubricants are used if no data has been specified Oil quality As standard, a mineral oil according to DIN , CLP 220 is used, Helical Gearbox D Instruction Manual 23

24 6 Service and maintenance Edition e.g.: BP ENERGOL GR-XP 220 ESSO Spartan EP 220 SHELL Omala Oel 220 Mobilgear 630 Aral Degol BG 220 Synthetic oils can also be used for special ambient conditions or where there are increased requirements placed on the gearboxes Oil level monitoring The oil level can only be visibly checked if the gearbox was ordered with an oil sight glass. Under normal operating conditions, the lubricant should be changed after operating hours however, at the latest every 4 years. The oil must be changed earlier than this under exceptional operating conditions, e.g. increased ambient temperatures or extreme temperature fluctuations. Checking the oil status The oil should only be checked when the gearbox is in a warm operational state immediately after the motor has been powered-down so that the oil has been optimally distributed in the gearbox. Danger Danger - hot gearbox oil can cause burns! Drain the oil at the oil drain plug (plug in accordance with DIN 908). Check the oil properties (color, consistency, metal particles). If the oil is dirty, change it. Dispose of the old oil in an environmentally friendly way Oil change The oil should only be changed when the gearbox is in a warm operational state. This allows all of the oil to be drained (the warm oil has a lower viscosity). Danger Danger - hot gearbox oil can cause burns! Place a container under the oil drain plug Remove the oil drain plug and also one oil filling plug. Completely drain the oil. If the oil is extremely dirty, flush out again (refer to Flushing)! Insert the oil drain plug and tighten to a torque corresponding to the following table. Fill new oil through the oil filling hole (the oil quantity is stamped on the rating plate). 24 Helical Gearbox D Instruction Manual

25 Edition Service and maintenance Tighten the oil filling plug or the vent valve to a torque corresponding to the following Table 6-1. Table 6-1 Tightening torque oil filling, oil drain plug, vent valve Plug Tightening torque [Nm] M10 x 1 5 M16 x Flushing If the oil is extremely dirty then we recommend that after the oil has been changed, the gearbox is flushed before new oil is filled. Take twice the quantity of flushing fluid than that specified for the quantity of oil. The flushing oil should have a viscosity of between mm²/s at 40 C. The flushing oil can be drained after several minutes with the gearbox operating under no-load conditions. By flushing several times, with the gearbox running under noload conditions, and if possible with alternating directions of rotation, the remainder of the old lubricant can also be completely removed and drained. Note Dispose of old oil in an environmentally-compatible fashion! 6.3 Mounting, disassembly, direct drive-in Gearbox sizes, D1 D5 2-stage 3-stage Fig. 6-1 Gearbox sizes D1 D5 Disassembly: 1.
