Idler gears transfer motion between two gears moving in the same direction or create space between them. Multiple idlers can be used to connect gears or get around obstructions. In a manual transmission, the reverse gear uses an idler gear to change the direction of rotation. When two gears are directly next to each other, […]
An idler wheel keeps a belt or chain taut and away from obstructions. Most are made of plastic or aluminum and rarely require maintenance. The tensioner bracket is responsible for maintaining the integrity of the serpentine belt system, and the idler wheel needs to be replaced when it starts to get noisy. An idler wheel […]
A belt idler pulley maintains proper tension on a fan belt, preventing excessive movement and belt pulling. It can be smooth or multi-ribbed and is commonly equipped with a zero-maintenance sealed bearing. A squeak or grinding sound may indicate a broken or weak spring or damaged bearing. A belt idler is a pulley that applies […]
Idler pulleys are used in automotive applications to replace non-existent accessories or provide tension to belts. There are four types of pulleys: crankshaft, accessory, idler, and AC idler. AC idler pulleys can replace air conditioning compressors or tension belts on vehicles with air conditioning. The term “idler pulley” can refer to a couple of different […]
An idler sprocket maintains chain tension in a chain drive system, preventing premature bearing and chain failure. It can be made of various materials and should be installed on the opposite side of the chain between the drive and driven sprockets. Maintenance is minimal. An idler sprocket is a device used to maintain tension in […]
