How to calculate the force acting on the gear ? Here i want to calculate the torque of the gear box. And we had 2 problems ,they are : 1 . Our conveyor gear box gear teeth is breaking ,its geared motor and the details details is RPM 1410 & gearbox will undergo few jerks . HP 20 Gear ratio 1410/40 2 . 6 "Rollers geared motor is tripping frequently , Motor details is 1.5 H.P Suggest me. Nithin

It sounds as though there is too much material on the conveyor.

Reasons for conveyor gear box gear teeth breaking could be due to high backlash between gear and pinion & less contact between them (besides overloading). Please check the contact at mesh area between gear and pinion. It should at least 50% in length as well as in width. In case of line contact at tip of the teeth (due to high backlash), whole torque is transmitted through a very small area resulting in extremely high cantilever force acting at root of the teeth. This force some times uproots the teeth.
