195-27-31220 SHAFT
The shaft is the core load-bearing and power transmission component in the mechanical transmission system of bulldozers, mainly used to support rotating parts such as gears, pulleys, bearings, etc., and transmit torque and motion. It is the "skeleton" that connects the various power systems, walking systems, and working devices of bulldozers. The working conditions of bulldozers are complex, and the shaft needs to withstand harsh conditions such as high load, impact vibration, and dust pollution. Therefore, it is necessary to have high strength, high toughness, wear resistance, and fatigue resistance.
Application of axis
transmission shaft
Function: Work in conjunction with the gearbox and drive axle to transmit engine power to the drive wheels, achieving the driving of bulldozers. As a high-speed, low support rotating body, its dynamic balance performance is crucial for transmission stability, and it needs to be adjusted through a dynamic balance test before leaving the factory.
Application: Widely used in the transmission system of tracked bulldozers, connecting the output end of the gearbox and the input end of the drive axle, especially suitable for the power transmission structure of special vehicles such as oil tankers and water trucks.
Universal joint shaft (cross shaft)
Function: The cross axis universal joint is used to achieve angle compensation between the transmission shaft, gearbox, and drive axle, adapting to the dynamic displacement of bulldozers during driving or operation.
Installation requirements: It is necessary to ensure that the universal joint forks at both ends are in the same plane to achieve constant speed transmission. The expansion joint should be close to the transmission end to reduce wear, and aligned with the balance mark and installed in place.
