Coupling sleeve assembly, double-shaft type servo motor and automatic equipment

Abstract

The invention provides a coupling sleeve assembly, a double-shaft type servo motor and automatic equipment. The coupling sleeve assembly comprises a coupling sleeve and a fixing piece, wherein the coupling sleeve is provided with a shaft sleeve hole in a penetrating mode in the axial direction; a first clamping part, a second clamping part and an air outlet groove set are arranged on the circumferential wall of the coupling sleeve, the first clamping part and the second clamping part are arranged in the circumferential direction of the coupling sleeve, a first fixing hole is formed in the first clamping part, a second fixing hole is formed in the second clamping part, and the fixing piece sequentially penetrates through the first fixing hole and the second fixing hole; the first clamping part and the second clamping part are stressed to move towards the shaft sleeve hole, and the air outlet groove set communicates with the shaft sleeve hole. According to the coupling sleeve assembly, the coaxiality error between the front shaft and the rear shaft can be reduced, so abrasion of the motor shaft is reduced, and installation is convenient.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a shaft coupling sleeve assembly, a double-shaft servo motor and automation equipment. Background technique [0002] see figure 1 , split servo motor generally consists of motor front shaft 11, main bearing 121, front end cover 131, middle end cover 132, stator 141, rotor 142, brake 15, rear end cover 133, auxiliary bearing 122, encoder 161, encoder cover 162. Composed of components such as the motor rear shaft 17, it is an electromagnetic device that uses a magnetic field as a medium to convert mechanical energy and electrical energy. It is currently widely used in various fields such as industrial robots and numerical control machine tools. [0003] Such as figure 2 As shown, the connecting block assembly inside the split motor includes a front axle end connecting block 111 , a plastic connecting block 18 and a rear axle end connecting block 171 . Positioning protrusions are...

Problems solved by technology

[0004] The advantage of this structure is to reduce the temperature rise of the encoder end. However, in the actual installation process, there are errors in the process of each part of the motor, and the final assembly of the plastic connection block 18 can only be seen with the eyes, and the axis of the motor front shaft 11 cannot be guaranteed. The center is consistent with the axis of the motor rear axle 17

There is a certain gap in the fit and assembly of this connecting block, which cannot be completely tightly matched, resulting in a further increase in the coaxiality error. Due to the process, the coaxiality of the front and rear axles is poor, which will generate torsion.

After the motor has been running for a long time, the front and rear axles are worn due to torque, which affects the life of the motor
