Bevel Gearbox Reduce The Speed
The axle gearbox is the last part of the drive system that transmits power to the wheel pair, reducing the speed of the drive shaft or hydraulic motor, increasing the torque and driving the wheel to rotate. Bevel Gearbox In a variety of large-scale road maintenance machinery, axle gear box structure, speed ratio is not the same, 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.
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, low-speed two sets of travel system, the high-speed travel using hydraulic mechanical transmission, low-speed travel using static hydraulic drive.
When the rammer is traveling at high speed, Bevel Gearbox the two axes of the front bogie are the driving shafts. The drive route is: engine → hydraulic torque converter → gearbox → output shaft → transfer case → drive shaft → axle gear box → wheel.
When the tamping machine 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 Box output shaft → drive shaft → transfer box → drive shaft → axle gear box → front bogie → wheel. At the same time, another oil motor (auxiliary motor) drives the rear of the bogie as an auxiliary drive to increase the wheel traction.
The structure of axle gearbox. Bevel Gearbox The gear box is used in Figure 4 shows the unipolar cylindrical gear mode, mainly composed of two shafts. The input shaft 5 is a first shaft whose inlet is connected to the motor by splines and a small straight cylindrical gear 8 which is slidable in the axial direction by means of splines. Bevel Gearbox The axle 3 is the second axis, Bevel Gearbox and the shaft is press-fitted with a large spur gear 1 to drive the axle to rotate. Bevel Gearbox The axle gearbox is provided with a cylinder-operated clutch which is engaged with the large cylindrical gear 1 by pushing the fork 7 on the clutch shaft 6 to drive the small straight cylindrical gear 8 to be engaged.
