Torque Calculation

[Johndesign123]

Hi All,

I need to calculate the Torque for a conveyor. It is a Roller conveyor each rollers are Connected with chain. Drive the roller gear motor to roller has connected by chain again. My concern is when we calculate the Torque we need to have PCD, In this case which sprocket PCD we should consider for Torque ( I mean Gear drive sprocket PCD or Roller Sprocket pcd)

Thanks,
John
