A 60 hp air pump blower in 18hr/day service running at a speed of 500 rpm is driven by means of a multiple v-belt drive which is powered by a compressor-stator motor with speed 1300 rpm. The center distance must be between 30 to 40 inches and the available driver sheave diameter iS 14 inches.
Recommend a multiple v-belt drive
that respects the following condition stated.
A 2hp motor is to drive a food shredder. The motor is projected to run at 1450 rpm and the required speed at the food shredder is 60 rpm. Design a double reduction drive consisting of belt and chain for this application.
Please give solution and show drawing if needed
A chain drive is desired to couple a gearmotor with a bucket elevator. The 40
hp. gearmotor will operate at 350 rpm and the elevator drive shaft must operate
as close to 60 rpm as possible. Select an appropriate chain size,
commercially available sprockets, and number of links for a chain. Also calculate
the actual chain speed and the center distance.
