A conveyor is driven by a 2.5-hp high-starting-torque electric motor through a flexible coupling to a worm-gear speed reducer, whose speed ratio is 35, and then via a roller chain to the conveyor shaft that is to turn about 12 rpm; motor rpm is 1750. Operation is smooth, 8 hr./day and service factor can be taken as 1.2. Decide the chain pitch in inch.

Question
A conveyor is driven by a 2.5-hp high-starting-torque electric motor through a flexible
coupling to a worm-gear speed reducer, whose speed ratio is 35, and then via a
roller chain to the conveyor shaft that is to turn about 12 rpm; motor rpm is 1750.
Operation is smooth, 8 hr./day and service factor can be taken as 1.2. Decide the
chain pitch in inch.
