# compute the maximum resisting torque that can be overcome by the system at the shaft axis

A 2Nm motor M is used to drive the system through a gear drive and a chain drive. the overall reduction ratio is to be between 16:1 and 18:1, and at an output speed of 6rpm.

• i would like to design a gear and chain drives of this system and select the suitable ball bearings for the shaft – dumisani mthethwa Nov 12 '19 at 10:05
$$T_{out,max} = i \cdot T_{mot,max} = 32 Nm \dots 36 Nm$$ for 'typical' electric motors at low speed.
