JOCKEY PULLEY Meaning and
Definition
-
A jockey pulley, also known as a tensioner pulley or idler pulley, is a rotating component used in mechanical systems that are driven by belts. It is designed to maintain the proper tension on the belt by adjusting its position or by applying a controlled force against the belt.
The jockey pulley is typically used in conjunction with other pulleys to redirect the belt's path and increase its contact area with the driving and driven pulleys. This arrangement allows for efficient power transfer and prevents slippage or excessive wear of the belt.
The jockey pulley is usually mounted on a movable arm or bracket, allowing for adjustment of the belt tension. This adjustment is crucial to ensure optimal performance and prevent premature failure of the belt and other related components. By maintaining the appropriate tension, the jockey pulley reduces vibrations, noise, and belt wear, thus extending the overall lifespan of the system.
In automotive applications, a jockey pulley is commonly found in the engine's accessory belt drive system, where it ensures proper tension on the serpentine belt that drives various accessories like the alternator, power steering pump, and air conditioning compressor.
Overall, a jockey pulley plays a vital role in belt-driven systems by providing tension control and ensuring smooth and reliable operation.

Etymology of JOCKEY PULLEY
The word "jockey pulley" has a clear etymology derived from its literal meaning.
The term "pulley" dates back to the 14th century and originates from the Old French word "polie", which means a small wheel with a groove or rim around which a cord or rope can run. The Old French word itself can be traced back to the Latin word "polos", which means "pivot" or "axis".
The word "jockey", on the other hand, is derived from the Middle English word "jogge", which means "to ride quickly". Over time, it developed to refer to a professional horse rider or someone who competes in horse racing.
