Bevel Gearbox Rapid Development

Sijie Industrial Co.,Ltd | Updated: Jul 27, 2017

With the rapid development of the railway industry, Bevel Gearbox for the railway construction, maintenance and repair of large-scale road maintenance machinery has also been rapid development. At present, widely used in China's large-scale railway road maintenance machinery are the following: tamping car, stable car, cleaning machine, Bevel Gearbox with ballast truck, rail grinding and so on. Each kind of mechanical axle gear box according to its own work needs, have their own unique drive design, but as an important part of the road maintenance machinery, Bevel Gearbox they must meet the following requirements: ① high-speed driving and can quickly enter and exit the block ; ② their own operations need to travel; ③ different types of mechanical linked to the needs of running. Bevel Gearbox This paper mainly analyzes the working structure and transmission principle of DC-32 tamping car and WD-320 stable axle gear box, Bevel Gearbox and explains the fault handling method through practical case.

The axle gearbox is the last part of the drive system that transmits power to the wheel pair, Bevel Gearbox reducing the speed of the drive shaft or hydraulic motor, increasing the torque, and driving the wheel to rotate. In a variety of large-scale road maintenance machinery, axle gear box structure, Bevel Gearbox speed ratio is not the same, Bevel Gearbox the current domestic use WD-320 stable car drive system and DC-32 tamping car basically the same, so the two axles Gearboxes are basically the same. Bevel Gearbox In this part of the structure of the structure of only tamping car axle gear box as an example to analyze.

DC-32 tamping car has three axle gear box, Bevel Gearbox divided into active bogie axle gear box (hereinafter referred to as axle gear box Ⅰ) and driven bogie axle gear box (hereinafter referred to as axle gear box Ⅱ) two types. DC-32 tamping car with high-speed, Bevel Gearbox low-speed two sets of travel transmission system, Bevel Gearbox the high-speed travel using hydraulic mechanical transmission, low-speed travel using hydrostatic transmission.

When the rammer is traveling at high speed, the two axes of the front bogie are the active shafts. The drive route is: engine → hydraulic torque converter → gearbox → output shaft → transfer case → drive shaft → axle gear box → wheel.

When the truck is running, it is required to start, brake or commut for the step-by-step tamping operation. The drive route is: engine → hydraulic gearbox → oil pump → oil motor → gear box → drive shaft → power change Box output shaft → drive shaft → transfer case → drive shaft → axle gear box → front bogie → wheel. Bevel Gearbox At the same time, another oil motor (auxiliary motor) drives a bogie of the axle as an auxiliary drive to increase the wheel traction force.

The axle gear case II is provided with a clutch operated by a cylinder, and when the high speed travels, the gear 8 is separated from the gear 1. When the work is running, the gear 8 is engaged with the gear 1 by the air control cylinder, and the axle becomes the driving shaft. Bevel Gearbox This type of axle gear box has a clutch shaft design, Bevel Gearbox so in the two conditions of conversion, Bevel Gearbox if the control part of the cylinder can not successfully complete the movement of gear 8, it will lead to damage to the entire transmission system, therefore, Bevel Gearbox usually must pay attention to Clutch air cylinder control part of the inspection and maintenance.
