Explanation & Use of Ratings & Service Factors Gear unit selection is made by comparing actual loads with catalog ratings. Catalog 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 catalog ratings. i.e. Equivalent Load = Actual Load x Service Factor Two types of Service Factor must be considered: Mechanical Service Factor Fm and Thermal Service Factor Ft Mechanical ratings and service factor Fm Table 1. Mechanical service factor Fm...

Selection Procedure Motorized Units EXAMPLE APPLICATION DETAILS Absorbed power of driven machine = 0.50 HP Output speed of gearbox or Input speed of machine = 58 RPM Application = Uniformly loaded belt conveyor Duration of service (hours per day) = 24hrs Ambient temperature = 68oF 1 DETERMINE MECHANICAL SERVICE FACTOR (Fm) Refer to Load Classication by Application, table 3, page 8 Application = Uniformly loaded belt conveyor Conveyors-uniformly loaded or fed apron assembly belt bucket chain Refer to mechanical service factor (Fm), table 1, page 7 Duration of service (hours per day) = 24hrs...

Selection Procedure Motorized Units 4 CHECK OUTPUT TORQUE Output torque of selected unit must be equal or more than required output torque at gearbox outputshaft. Required output torque at gearbox outputshaft = 389 lb.in Selected unit’s output torque = 700 lb.in, therefore unit is acceptable (See B0410 30:1 reducer rating on page 65) 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 OUTPUT OUTPUT MECH RATIO TORQUE SPEED S.F. (LB-IN) UNIT DESIGNATION Selected unit’s service factor (Fm) =...

Selection Procedure Reducer Units EXAMPLE APPLICATION DETAILS Absorbed power of driven machine = 0.375 HP Output speed of gearbox or Input speed of machine = 30 RPM Application = Uniformly loaded belt conveyor Duration of service (hours per day) = 24 hrs Motor speed = 3 phase electric motor, 4 pole, 1750 RPM Ambient temperature = 68oF 2 DETERMINE MECHANICAL SERVICE FACTOR (Fm) Refer to Load Classication by Application, table 3, page 7 Application = 1 DETERMINE RATIO OF GEARBOX REQUIRED Motor speed Gearbox output speed Refer to rating tables (pages 65 - 68) for nearest standard ratio...

Selection Procedure Reducer Units If the application requires greater output torque then the input power must be increased, in which case the input power rating of the reducer must be checked. Required motor power = Input power x 100 Efciency Next largest motor is 0.75 Hp (The B0610 60:1 is rated for 0.98 Hp and is acceptable) 6 DETERMINE THERMAL SERVICE FACTOR (Ft) 6 DETERMINE THERMAL SERVICE FACTOR (Ft) Refer to table 2, page 6 Refer to table 2, page 7 Ambient temperature = 68oF Ambient temperature = 68oF 7 CHECK THERMAL CAPACITY OF GEARBOX SELECTED DETERMINE THERMAL INPUT POWER CAPACITY...
