In order to prevent the low natural vibration frequency of the drive shaft, how to prevent the vibration of the drive shaft? At high speed, the co-seismic surface causes strong vibration of the drive shaft. Usually, the car drive shaft is selected as a hollow shaft.

1. Avoid the deformation of the transmission shaft, ensure that the telescopic fork and shaft tube point to mark in the assembly line, the rotor dynamic balance sheet does not fall down, and the welding and repair of the transmission shaft does not tilt, so as to maintain the balance of the transmission shaft.

2. If the cross shaft motor shaft of universal coupling and the rolling bearing are damaged and cooperate with each other too much, or the distance between the inner hole of the cross shaft of the motor shaft and the middle of the management center of the cross shaft is too large, which leads to the shaking of the cross shaft, it will also make the pivot line of the drive shaft shift its arc axis, causing the shaking condition should be repaired or replaced immediately.

3. If the anchor bolt at the connection between the transmission shaft and the gearbox or the rear axle boss of the automobile is loose, it should be tightened in accordance with the specified torque.

How to prevent shafts from shaking? In order to prevent the low natural vibration frequency of the drive shaft and the strong vibration of the drive shaft caused by the common vibration surface at high speed, the hollow shaft is usually selected for the car drive shaft. Because in the transmission of the same torque condition, the hollow shaft has a higher critical speed ratio, in order to make the drive shaft only long, some vehicles to drive shaft into each section and installed in the middle of the support plate, and all the drive shaft before loading after rotor dynamic balance experiment.

Therefore, in the application and maintenance of the whole process, must ensure the following three points: (1) to avoid the deformation of the transmission shaft, to ensure that the assembly line telescopic fork and shaft tube pointing mark, the rotor dynamic balance sheet does not fall, welding repair transmission shaft is not tilted, in order to maintain the balance of the transmission shaft. (2) such as universal coupling cross shaft motor shaft and rolling bearing after damage with each other is too open, or cross shaft motor shaft inner hole to the middle of the cross shaft management center specification distance is too large lead to the shaking of the cross shaft, will also make the drive shaft pivot line offset its arc axis, resulting in shaking should be repaired or replaced immediately. (3) If the anchor bolt at the connection between the transmission shaft and the gearbox or the rear axle boss of the automobile is loose, it should be tightened in accordance with the specified torque.

The drive shaft has a solid shaft and a hollow shaft. How to prevent shafts from shaking? In order to reduce the quality of the drive shaft, save materials, improve the strength and stiffness of the shaft, the drive shaft is mostly hollow shaft, generally with a thickness of 1.5 ~3.0mm of thin steel coil welding, super heavy truck is directly using seamless steel pipe.

The drive shaft is the main force transmission component in the universal transmission device. How to prevent shafts from shaking? It is usually used to connect the transmission (or sub-brake) to the drive axle and, in the case of the steering drive axle and the split drive axle, to connect the differential to the drive wheels.

For tight bearings, how to prevent shafts from shaking? You can hold the drive shaft or the telescopic sleeve by hand and knock the universal joint fork with a hammer to make the cross shaft impact the bearing sleeve and shake out the roller needle.
