[0002] A spline sleeve is a mechanical part used to connect and transmit torque. It is usually made of metal material and has high strength and wear resistance. The surface of the spline sleeve is usually processed with spline teeth, which can mesh with the spline teeth of other parts (such as gears, shafts, etc.). When the spline sleeve is connected to other parts, the meshing surfaces between them will produce a large contact stress, thereby being able to transmit a large torque. In practical applications, spline sleeves are widely used in various mechanical equipment, such as motors, reducers, automobile transmission systems, etc. The design and manufacture of spline sleeves need to take into account many factors such as materials, strength, hardness, wear resistance, etc., in order to meet the use requirements under different working conditions.

[0003] The motor rotor spline sleeve is a connecting component used on the motor rotor. However, the traditional spline sleeve still has some shortcomings. For example, its structure is relatively fixed and the connection with the connecting component is relatively tight. Therefore, it is difficult to disassemble it when it needs to be replaced or maintained, making the maintenance process time-consuming, labor-intensive and inefficient. Therefore, a motor rotor spline sleeve is proposed to address the above problems. Utility Model Content
