What is a sheave and pulley?
Sheaves and pulleys are wheels with a flat or grooved edge that transmit rotational force from one shaft to another when connected with a V-belt or gearbelt. They are used to power fans, pumps, and conveyors.
What is a motor sheave?
A sheave (/ʃiːv/) or pulley wheel is a grooved wheel often used for holding a belt, wire rope, or rope and incorporated into a pulley. This allows the wire or rope to move freely, minimizing friction and wear on the cable. Sheaves can be used to redirect a cable or rope, lift loads, and transmit power.
What are sheaves mechanical?
A sheave (pronounced “shiv”) is a wheel or roller with a groove along its edge for holding a belt, rope or cable. When hung between two supports with a belt, rope or cable, one or more sheaves make up a pulley. The words sheave and pulley are sometimes used interchangeably.

- Fixed: A fixed pulley has an axle mounted in bearings attached to a supporting structure.
- Movable: A movable pulley has an axle in a movable block.
- Compound: A combination of fixed and movable pulleys forms a block and tackle.

Is an idler pulley the same as a tension pulley?
The physical difference between an idler pulley and a tensioner pulley is a simple adjustable bolt. Tensioner pulleys are mounted on this bolt, and idler pulleys are not. They also differ in purpose. Idler pulleys spin in order to move belts to different places.
What is a pulley sheave?
Pulley block including sheave. A sheave (/ʃiːv/) is a pulley with a grooved wheel for holding a belt, wire rope, or rope. The grooved wheel spins on an axle or bearing inside the frame of the block. This allows the wire or rope to move freely minimizing friction and wear on the cable.
What is a driven pulley?
A driven pulley is a pulley connected to a belt that moves in reaction to a driving pulley powered by a motor or some other energy source. It is a reactive component within a pulley system and is not capable of driving the system on its own.
