SERIES M3 Fluid & Power EXPLANATION & USE OF RATINGS & SERVICE FACTORS 0503 Gear unit selection is made by comparing the actual loads with catalog ratings. Catalog ratings are based on a standard set of loading conditions, whereas actual load conditions vary according to the type of application. Service Factors are therefore used to calculate an equivalent load to compare with catalog ratings. i.e. Equivalent Torque = Application Torque x Service Factor Mechanical Service Factor 1. Calculate total external inertia (gearbox inertia + load inertia reflected to the gearbox input). 2. Determine motor...

SERIES M3 Fluid & Power OVERHUNG & AXIAL LOADS (lbf) ON SHAFTS 0503 Maximum permissible overhung loads When a sprocket, gear etc. is mounted on the shaft, the calculation 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, etc. should be mounted on a separate shaft, flexibly coupled and supported in its own bearings, or the gear unit shaft should be...
