& SERVICE FACTORS 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 Mechanical ratings and service factor Fm Mechanical ratings measure capacity in terms of life and/or strength, assuming 10 hr/day continuous running under uniform load conditions. Catalogue ratings allow 100% overload...

SELECTION PROCEDURE 4 CHECK OUTPUT TORQUE Output torque (M2) of selected unit must be equal or more than required output torque at gearbox outputshaft. Required output torque at gearbox outputshaft = 98 Nm. However the output torque is only 84 against the requirement of 98 Nm, hence a unit fitted with a 1.1 kW motor is required (page 41). Selected unit's output torque (M2) = 123 Nm, therefore the torque from a 1.1 kW motor is acceptable. 5 CHECK SERVICE FACTOR Service factor (Fm) of selected unit must be equal or more than required service factor. Required service factor of gearbox = 1.25 UNIT...
