An Idler Gear is used in engines to transmit rotational motion between two gears or shafts. The primary function of the idler gear is to transmit rotary movement from one shaft to another parallel shaft with proper gear mesh. It acts as an intermediary gear, ensuring smooth and efficient power transmission between other engine components.Attributes:• Ensures that power is distributed evenly and efficiently• Helps to reduce the size of the drive engineApplications:An Idler Gear has a specific number of teeth, which must match the pitch diameter and tooth profile of the driving and driven gears to ensure proper meshing and consistent power transmission.
