Liberation of diesel car gearbox bearing ablation

Liberation of diesel car gearbox bearing ablation - 2020 04 - 10 a free car, to use is 6 block transmission. In use, found that the second shaft transmission gear needle roller bearing and the second axis back-end roller bearing ablation. Fault diagnosis rule out: the practice proves that the cause of the damage phenomenon, is driving more lubricating oil shortage caused by improper operation and the transmission. The car six block transmission on the shaft of the second one to five gear gear intermediate photogenic corresponding gear meshing, the second reverse gear on a shaft and intermediate shaft soil reverse gear meshing. Due to the second axis of these gears are through with the needle roller bearing cage floating on the second shaft, therefore they are corresponding to the gear of the reverse gear on the intermediate shaft drive, turn over the second shaft, does not affect the second axis of rotation. On the other hand, the constant mesh gear transmission ratio of each are not identical. So first transmission shaft is rotated, the gear on the second shaft rotates at different speed. Under normal circumstances, intermediate shaft rotating gear oil splash up every second shaft gear lubrication. And through the oil hole of each gear oil, lubrication needle roller bearing, and after the second shaft bearing. Under the car because of driving in the mountains all the year round, big long slope more time. If often shut down slide block, make the transmission of the first shaft and intermediate shaft all cannot turn, only by the rear axle shaft power to the transmission from the second axis of rotation. Because of the intermediate shaft rotation, transmission gear oil is left in less than a second shaft. The second shaft of the gear because not enough oil, time is a bit long, the needle roller bearing block and the second axis bearing will due to lack of lubrication, and form a half dry friction, eventually lead to the bearing ablation. Therefore, when driving a car should stall is forbidden to take off the slide block. When maintenance, should pay attention to check the amount of lubricating oil transmission. Due to the transmission parts, small gap can be divided into two filling lubricating oil. A foot, let the transmission operation for a period of time secondary to upper limit. （ Source: web)
