Abstract

The invention discloses a spline shaft dismounting device, used for taking out a spline shaft with the top extending out of a sleeve from the sleeve. The spline shaft dismounting device comprises: a fixed cylinder body provided with an external thread on the outer surface and sleeved and fixed to a sleeve; a torsion barrel provided with a threaded hole matched with the external thread, wherein the torsion barrel moves in the axial direction of the fixed barrel through rotary matching of the threaded hole and the external thread; an elastic lining sleeved and fixed to the top of the spline shaft, wherein the elastic lining faces the end face of the torsion cylinder and is used for being in contact with the torsion cylinder. when the torsion cylinder is controlled to move in the direction facing the elastic lining, the torsion cylinder applies acting force to the end face, facing the torsion cylinder, of the elastic lining, so that the elastic lining and the spline shaft are synchronously pushed away from the sleeve by the torsion cylinder, and then the spline shaft is separated from the sleeve; the device which is convenient to operate and simple in structure solves the problem that the spline shaft is difficult to disassemble during interference fit connection.

Description

technical field [0001] The invention relates to the technical field of mechanical assembly disassembly equipment, in particular to a spline shaft disassembly device. Background technique [0002] Spline connection is widely used in mechanical transmission connection assemblies because of its simple structure, easy processing, and ability to transmit torsion. Generally speaking, the spline connection often adopts a clearance fit, which is relatively easy to disassemble, and there is no situation where the spline shaft is difficult to disassemble from the assembly, but when the spline connection has an interference fit with a large amount of interference, It can be difficult to disassemble the splined shaft from the splined assembly. [0003] A common example is: when an engine is overhauled, the interference fit of the spline connection has often been bonded during the use of the previous life cycle. In addition to a certain amount of interference, the spline shaft is even m...
