10 5 SERIES G Gear unit selection is made by comparing actual loads with catalogue ratings. Catalogue ratings are based on a standard set of loading conditions, whereas actual load conditions vary according to type of application. Service Factors are therefore used to calculate an equivalent load to compare with catalogue ratings. i.e. Equivalent Load = Actual Load x Service Factor echanical and Thermal Service Factor must be considered:- echanical Service Factors Fm and Fs Thermal Service Factors Ft, Fd, Fh and Fv echanical ratings and service factors Fm and Fs echanical ratings measure capacity in terms of life and/or strength, assuming 0 hr/day continuous running under uniform load conditions. Catalogue ratings allow 00% overload at starting, braking or momentarily during operation up to 0 times per day. The unit selected must therefore have a catalogue rating at least equal to half maximum overload. echanical Service Factor Fm (Table ) is used to modify the actual load according to daily operating time, and type of loading. Required mechanical power rating P(mech) = absorbed power x Fm Load characteristics for a wide range of applications are detailed in Table 3 opposite, which are used in deciding the appropriate Service Factor Fm from Table. If loading can be calculated, or accurately assessed, actual loads should be used instead modifying using Fm. For units subject to torque reversal or frequent stop/start overloads in excess of 0 times per day, the following check should be made gear unit input power capacity (kw) > Tm x Fs x n 2 x 9550 n = input speed (rev/min) Fs = number of starts factor (See table 2) For applications where high inertia loads are involved e.g. crane travel drives, slewing motion etc, or when units are to operate in extremely dusty or moist/humid atmospheres, unit selection should be referred to our Application Engineers.

12 EXPLANATION AND SE OF RATINGS AND ASSOCIATED RATING FACTORS Thermal ratings and service factors The Thermal ratings are a measure of the gear units ability to dissipate heat. If they are exceeded the lubricant may overheat and breakdown, resulting in gear failure. Thermal ratings are given on page 32 for parallel shaft units and page 46 for right angle shaft units. The following choices are available: i) No additional cooling Catalogue thermal limitations are based on the unit operating continuously in an environment with an ambient temperature equal to 25 o per hour, altitude and operating area. To account for these varying conditions, the service factors given in tables 4, 5, 6 and 7 should be applied as follows:- Ptherm = Absorbed Power Ft x Fd x Fh x Fv Ptherm = Required thermal rating (kw) Ft = Service factor for ambient temperature (see Table 4) Fd = Service factor for intermittent duty (see Table 5) Fh = Thermal service factor for altitude (see Table 6) Fv = Thermal service factor for air velocity correction (operating area) (see Table 7) Table 4.

24 aximum permissible overhung loads SERIES G When a sprocket, gear etc. is mounted on the shaft a calculation, as below, must be made to determine the overhung load on the shaft, and the results compared to the maximum permissible overhung loads tabulated. Overhung loads can be reduced by increasing the diameter of the sprocket, gear, etc. If the maximum permissible overhung load is exceeded, the sprocket, gear, extended to run in an outboard bearing. Alternatively, a larger gear is often a less expensive solution. Permissible overhung loads vary according to the direction of rotation. The values tabulated are for the most unfavourable direction with the unit transmitting full rated power and the load P applied midway along the shaft extension. ence they can sometimes be increased for a more favourable direction of rotation, or if the power transmitted is less than the rated capacity of the gear unit, or if the load is applied nearer to the gear unit case. Refer to our Application Engineers for further details. In any event, the sprocket, gear etc. should be positioned as close as possible to the gear unit case in order to reduce bearing loads and shaft stresses, and to prolong life. All units will accept 00% momentary overload on stated capacities. Overhung load (Newtons) Overhung member P = kw x 9,500,000 x K N x R where P = equivalent overhung load (Newtons) kw = power transmitted by the shaft (kilowatts) N = speed of shaft (rev/min) R = pitch radius of sprocket, etc. (mm) K = factor Note: Newton = kg = lbs.

Similarly they can sometimes be increased if the power transmitted is less than the rated capacity of the gear unit. Thrust capacities tabulated refer to outputshafts, and are calculated without any overhung loads being applied.

69 IPORTANT Product Safety Information General - The following information is important in ensuring safety. It must be brought to the attention of personnel involved in the selection of the equipment, those responsible for the design of the machinery in which it is to be incorporated and those involved in its installation, use and maintenance. The equipment will operate safely provided it is selected, installed, used and maintained properly. As with any power transmission equipment proper precautions must be taken as indicated in the following paragraphs, to ensure safety. Potential azards - these are not necessarily listed in any order of severity as the degree of danger varies in individual circumstances. It is important therefore that the list is studied in its entirety:- ) Fire/Explosion (a) Oil mists and vapour are generated within gear units. It is therefore dangerous to use naked lights in the proximity of gearbox o C), certain materials (rubber, plastics, etc.) may decompose and produce fumes. Care should be taken to avoid exposure to the fumes, and the remains of burned or overheated plastic/rubber materials should be handled with rubber gloves. 2) Guards - Rotating shafts and couplings must be guarded to eliminate the possibility of physical contact or entanglement of clothing. It 3) Noise - igh speed gearboxes and gearbox driven machinery may produce noise levels which are damaging to the hearing with prolonged exposure. Ear defenders should be provided for personnel in these circumstances. Reference should be made to the Department of Employment Code of Practice for reducing exposure of employed persons to noise. 4) Lifting - Where provided (on larger units) only the lifting points or eyebolts must be used for lifting operations (see maintenance manual or general arrangement drawing for lifting point positions). Failure to use the lifting points provided may result in personal injury and/or damage to the product or surrounding equipment. Keep clear of raised equipment. 5) Lubricants and Lubrication lubricants. (b) The lubrication status of the equipment must be checked before commissioning. Read and carry out all instructions on the lubricant plate and in the installation and maintenance literature. eed all warning tags. Failure to do so could result in mechanical damage and in extreme cases risk of injury to personnel. associated equipment, in order to prevent the machinery being started. 7) Installation, aintenance and Storage (a) In the event that equipment is to be held in storage, for a period exceeding 6 months, prior to installation or commissioning, application engineering must be consulted regarding special preservation requirements. nless otherwise agreed, equipment must be stored in a building protected from extremes of temperature and humidity to prevent deterioration. The rotating components (gears and shafts) must be turned a few revolutions once a month (to prevent bearings brinelling). (b) External gearbox components may be supplied with preservative materials applied, in the form of a "waxed" tape overwrap or wax white spirit as a solvent. Preservatives applied to the internal parts of the gear units do not require removal prior to operation. personnel. (d) Before working on a gearbox or associated equipment, ensure that the load has been removed from the system to eliminate the possibility of any movement of the machinery and isolate power supply. Where necessary, provide mechanical means to ensure the machinery cannot move or rotate. Ensure removal of such devices after work is complete. (e) Ensure the proper maintenance of gearboxes in operation. se only the correct tools and approved spare parts for repair and maintenance. Consult the aintenance anual before dismantling or performing maintenance work. 8) ot Surfaces and Lubricants equipment to cool before servicing or performing adjustments. 9) Selection and Design (a) Where gear units provide a backstop facility, ensure that back-up systems are provided if failure of the backstop device would endanger personnel or result in damage. (b) The driving and driven equipment must be correctly selected to ensure that the complete machinery installation will perform satisfactorily, avoiding system critical speeds, system torsional vibration, etc. (c) The equipment must not be operated in an environment or at speeds, powers, torques or with external loads beyond those for which it was designed. (d) As improvements in design are being made continually the contents of this catalogue are not to be regarded as binding in detail, and drawings and capacities are subject to alterations without notice. the gear units.
