Selection guide and Power rating of Worm Gear Boxes.

For Gear Unit selection Prime mover's maximum power rating can be taken as base for determining the actual load. The Gear Selection is made by comparing actual transmitted loads with catalogue ratings. It is important to realise that are based on standard set of load conditions, which invariably change for different conditions. Therefore service factor must be used to calculate a theoratical transmitted load or equivalent load, before comparing with catalogue rating. For calculating the same, apply the formula:-

Equivalent Load = Actual Load x Service Factor

These are some Suggestions to improve the performance of your worm speed reducers, worm gear boxes or worm geared drives. However, please note that these are suggestions based on standard set of conditions. If these are different from your results, please rely on your results and inform us.
