The "idler wheel" in bulldozer spare parts is a key component in the tracked walking system. It primarily supports and guides the tracks, ensuring their correct movement, and also bears part of the machine's weight. In mechanical transmission, an idler wheel (also called a gear between two gears that are not in direct contact) is a gear that plays a transmission role. It can change the rotation direction of the driven gear, making it the same as the driving gear, but it does not change the transmission ratio.
Changing Direction: In a gear train, the idler wheel can adjust the rotation direction of the output gear.
Stabilizing the System: As a "lazy wheel," the idler wheel does not rotate actively, but it can maintain the consistent direction of the front and rear gears through meshing, enhancing transmission stability.
Track support: In bulldozers, idler wheels, guide wheels, and track rollers work together to support the tracks, prevent excessive sagging, and guide their movement.
