An Idler Gear is used in the transmission system of a vehicle. It is typically located between the reverse gear and the output shaft and is responsible for maintaining proper spacing between the gears in the gear train. That rotates freely on its shaft and meshes with the other gears in the gear train to transmit torque and rotational motion,Attributes:• Designed to be compact and can be used in confined spaces• Provided with key space in the gear arrangement for proper alignmentApplications:An Idler gear converts the fluid pressure into mechanical energy to drive machinery efficiently, provided with key space in the gear arrangement for proper alignment.
