[0002] A spline sleeve is a mechanical connector that matches a shaft and is often used to achieve rotational transmission. It is often a sleeve-shaped part with grooves inside that match the splines on the shaft to achieve fixation and transmit torque. The design and manufacture of the spline sleeve needs to consider factors such as the size and shape of the splines on the shaft and sleeve to ensure the matching and transmission accuracy between the sleeve and the shaft.

[0003] When the existing high-precision rotating spline sleeve structure is used in conjunction with a spline shaft, the inner wall of the spline sleeve is easily worn severely. If it is not lubricated in time, the service life of the spline sleeve is easily shortened. In addition, since the spline sleeve is adapted to the spline shaft, it is inconvenient to embed the spline shaft into the spline sleeve. Therefore, a high-precision rotating spline sleeve is needed to solve the above problems. Utility Model Content

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1.
