Deep Groove Ball Bearing Specification

Deep Groove Ball Bearing Description

The reasons for the failure of the automobile gearbox bearing are: the gear meshing gap is abnormal; the metal on the tooth surface of the gear is peeled off, the teeth are broken, and the assembly is dislocated; the lack of lubricating oil causes poor lubrication; Abnormal noise problem; the bolts of the gearbox casing are loose; the groove of the shift lever and the shift fork in the manual gearbox is loose; the inferior automatic transmission oil has been replaced. The gearbox is a device that changes the speed ratio and the direction of movement. It is used in automobiles, tractors, ships, machine tools and various machines to change the torque, speed and direction of movement from the driving shaft to the driven shaft according to different working conditions. . Gearbox, also known as transmission, is used to change the speed and torque from the engine, and can fix or divide gears to change the transmission ratio of the output shaft and the input shaft. There are three types of automatic transmissions commonly used in automobiles, namely cvt transmission, dual clutch transmission and AT transmission.
