Description
Technical Field
The utility model relates to a transmission shaft technical field, concretely relates to take transmission shaft of balancing piece.
Background
The transmission shaft consists of a shaft tube, a telescopic sleeve and a universal joint. The telescopic sleeve can automatically adjust the change of the distance between the transmission and the drive axle. The universal joint ensures the change of the included angle between two axes of the output shaft of the speed changer and the input shaft of the drive axle and realizes the equal angular speed transmission of the two shafts. The transmission shaft is a fitting for a round object which is movable or rotatable by connecting or assembling various fittings, and is generally made of a light alloy steel pipe having excellent torsion resistance. In a front engine rear wheel drive vehicle, the propeller shaft is the shaft that transmits the rotation of the transmission to the final drive and may be connected by a multi-joint universal joint. The transmission shaft is a high-speed, low-bearing rotating body, so that the dynamic balance of the transmission shaft is crucial. Generally, a dynamic balance test is carried out on a transmission shaft before leaving a factory, and the transmission shaft with poor balance is adjusted by a method of welding a balance block.
However, the high temperature generated by the connection of the balance weight by welding affects the use of the transmission shaft, and the operation is troublesome.
