What does the idler pulley mount to?
Function. The idler pulley is one pulley in a set that drives the belt system of a vehicle. The idler pulley regulates the belts that connect to the crankshaft and are used to produce movement in numerous engine accessories, such as the alternator, steering pump and air-conditioner compressor.
How are two pulleys used in a belt system?
Two pulleys can be used to create a simple belt and pulley system, in which a belt is looped between the two pulleys. One pulley is the “driving pulley”, and as it spins, it transmits power through the belt either via friction or teeth, thus spinning a “driven pulley”.
What do you call the supporting shell of a pulley?
In the case of a pulley supported by a frame or shell that does not transfer power to a shaft, but is used to guide the cable or exert a force, the supporting shell is called a block, and the pulley may be called a sheave. A pulley may have a groove or grooves between flanges around its circumference to locate the cable or belt.
What happens when a belt falls off a pulley?
The belt becomes lose and is unable to maintain required tension. When belt wobbling continues for some time, it can partially or fully push the belt off the pulley so the pulley continues rotating with nothing on it.
Which is the last pulley to fit on a lawn mower?
The last pulley to fit is the crank pulley (engine pulley). A tension-ed belt, is a deck drive belt that is always tight on the pulleys.

What’s the difference between a fixed and movable pulley?
Fixed Pulley: A pulley whose axis is fixed in place. It can rotate, but it cannot translate in any direction freely. Movable Pulley: A pulley that can both rotate and translate based on the motions of the pulley or belt.

What kind of pulley can rotate and translate?
Fixed Pulley: A pulley whose axis is fixed in place. It can rotate, but it cannot translate in any direction freely. Movable Pulley: A pulley that can both rotate and translate based on the motions of the pulley or belt. This is commonly used in block and tackle systems, which I’ll explain later.
