Description

Technical Field

[0001] The utility model relates to the technical field of press-fit connection, in particular to a transmission shaft moving joint press-in device. Background Art

[0002] A drive shaft usually refers to a mechanical shaft used to transmit power and torque. They can transfer power from the engine to the drive wheels of a vehicle or the working parts of a mechanical device. A movable joint is a movable connecting part in a mechanical device. It is usually used to connect two parts and allow them to move relative to each other. The design of the movable joint allows adjacent parts to move relative to each other when necessary while maintaining sufficient connection strength and stability.

[0003] The existing transmission shaft and movable joint are connected by splines. When the movable joint and the transmission shaft are connected, the splines of the movable joint and the transmission shaft need to be connected. When the existing transmission shaft and movable joint are pressed into each other, the transmission shaft and the movable joint often need to be pressed into the equipment for fixing. After the transmission shaft and the movable joint are fixed, the transmission shaft and the movable joint cannot correspond to each other. Furthermore, when the transmission shaft and the movable joint are misaligned, it is inconvenient to adjust them. Therefore, the wire is easily broken when pressed in, resulting in unqualified product quality and poor stability.

[0004] For this purpose, a transmission shaft movable joint pressing device is proposed. Utility Model Content
