Features of the front idler
The front idler is a wheel that does not perform work, and has a certain energy storage effect, which is helpful to the stability of the system. Idler wheels are very common in machinery and it helps to connect shafts in the distance. It just changes the steering and does not change the gear train transmission ratio.
The difference between front idler, tensioner and guide wheel
Front idler gear is a gear that is sandwiched between two gears and meshes with both gears. Its role is only to change the relationship between the rotation direction of the two gears before and after it.
Tensioning wheels appear in belt drive or chain drive. Its role is to tension the belt or chain, reduce the vibration and energy loss during their movement, and change the position.
The guide wheel, as the name suggests, mainly plays a guiding role. In the design of the wheel train, in order to meet the design requirements and overall dimensions, the direction of the belt is more complicated. The steering wheel is designed to meet the design angle in achieving the design requirements.
