The internal meshing of the drum gear coupling has the same number of teeth, which is divided into two types: straight teeth and drum teeth. The spherical surface is located on the gear shaft. The tooth side clearance is larger than that of ordinary gears. Roller gear couplings. Can allow larger angular displacement (compared to straight tooth coupling). It can improve tooth surface contact, increase torque capacity, and extend the service life of the transmission device.

In the work of the gear clutch, the two shafts produce relative displacement. The transmission shaft is usually a thick and uniform shaft. The two ends of the shaft are welded with universal joint forks and splined shaft heads. The sliding sleeve is in the middle of the transmission shaft structure, and one end of the shaft head is connected to the flange plate through the spline; In the rear drive shaft structure, the sliding sleeve and the axle fork cooperate with each other.

The axle fork can slide axially along the sliding sleeve so that the sliding sleeve can slide axially. The transmission shaft can be extended and contracted to adapt to the relative relationship between the rear axle and the frame during automobile operation. When the position changes, the two ends of the transmission shaft are respectively connected with the input shaft and the output shaft by a cross shaft universal joint. 1. Before leaving the factory, the assembly of the drive shaft must be strictly inspected, and the balance sheet must be welded in the appropriate position to meet the dynamic balance requirements of the drive shaft assembly.

In order to ensure the original assembly position of the moving shaft, spray two relatively white painted arrows on the outer surface of the shaft tube of the rear drive shaft and the spline sliding fork to ensure that the assembly position of the drive shaft is checked before leaving the factory. In addition, all disassembled drive shafts must be installed in a straight line when reinstalling. 3. When installing the rear axle assembly on the whole vehicle, the opening of the sliding spline sealing sleeve should be provided to prevent the transmission shaft from entering the rain cement sand from the matching key, which affects the service life of the transmission shaft. 4. When the transmission shaft isOEM UF CV Joint Manufacture designed and arranged on the whole vehicle, ensure that the product nβ of the working angle β of the transmission shaft universal joint and the rotation speed n of the transmission shaft is less than 18,000.
