[0002] The drive shaft is an important component in the transmission device. Its function is to connect the power output end and the final output end. It is divided into full-floating drive shaft, semi-floating drive shaft and universal joint drive shaft. But no matter which type, its main structure has shaft tube, universal joint, bracket and connector. Among them, the universal joint can compensate for the angle and distance changes between the power output end and the final output end, and the bracket is an important component for supporting and fixing the drive shaft.

[0003] The drive shaft bracket is used to ensure that the drive shaft maintains the correct position during use, reduces vibration, and withstands the torque and inertia force transmitted by the drive shaft. The design and installation of the drive shaft bracket are essential to ensure the normal operation of the transmission device. Therefore, during maintenance and inspection, attention should be paid to inspecting and maintaining the drive shaft bracket, especially checking the tightness of the fixing bolts to ensure the stability of the bracket.

[0004] When installing the existing drive shaft bracket to the drive shaft, the drive shaft is held by hand to align it with the pressure head of the hydraulic equipment and keep it from shaking. Finally, the hydraulic equipment is started by using a foot switch, and the drive shaft bracket and the center connecting fork are pressed into the drive shaft by the downward force of the pressure head of the hydraulic equipment. However, the assembly process relies entirely on experience to align the center connecting fork with the pressure head during assembly. Such an operation cannot be accurately aligned. During the downward pressure of the hydraulic equipment, the spline part thereof will be damaged, resulting in a reduction in the service life of the rotating shaft and reduced installation efficiency.
