The torque shaft has two sections of splines. The torque shaft passes into the coal mining machine motor shaft. The motor shaft is connected to one section of the torque shaft spline, and the other section of the torque shaft spline is connected to the coal mining machine reducer; during the working process, the torque shaft completes the transmission of mechanical energy. The torque shaft is a vulnerable part in the coal mining machine equipment, and the phenomenon of tooth breaking and twisting often occurs. For coal mines with small space, it is not desirable to disassemble the coal mining machine host or the motor to replace the vulnerable part such as the torque shaft. Summary of the invention

[0003] The utility model aims to provide a motor with a torque shaft which can be easily disassembled.

[0004] A motor with an easily detachable torque shaft comprises a motor body, a motor shaft rear cover, a detachable torque shaft, a plugging cover, a retaining ring and a junction box. The junction box is assembled with the motor body. The motor shaft rear cover is assembled at the rear end of the motor body through a fastener. The plugging cover and the retaining ring are assembled inside the rear end of the hollow shaft of the motor body. One end of the detachable torque shaft is inserted into the hollow shaft of the motor body from the front end of the hollow shaft of the motor body. A shearing groove is provided at one end of the detachable torque shaft, and a disassembly thread is provided inside the end.

[0005] Preferably, torque shaft splines are provided at both ends of the detachable torque shaft, the torque shaft spline at one end of the detachable torque shaft is fitted with the hollow shaft of the motor body, and the torque shaft spline at the other end of the detachable torque shaft is used to connect with the coal mining machine.

[0006] Preferably, the detachable torque shaft is semi-hollow, and the semi-hollow is arranged at the shear groove.

[0007] The utility model fixes the rear cover of the motor shaft with screws, then installs the retaining ring into the hollow shaft of the motor body, and then assembles the plugging cover. One end of the detachable torque shaft is inserted from the hollow shaft of the motor body. The retaining ring and the plugging cover prevent the detachable torque shaft from moving axially. The part remaining inside the coal mining machine and the motor body is designed to be threaded, and the remaining part of the torque shaft can be taken out with a long threaded screw. A shearing groove is designed in the detachable torque shaft to purposefully leave a section of the torque shaft inside the coal mining machine and the motor, and this section of the torque shaft can be taken out with a long threaded screw. As a vulnerable part of coal mining equipment, the detachable torque shaft should be easy to install, disassemble, and replace during use. In this way, the structural design of the utility model realizes the easy installation, disassembly, and replacement of the torque shaft, effectively reduces the labor intensity of coal miners, and effectively ensures production efficiency.

[0011] In order to make the technical solution of the present utility model easier to understand, the technical solution of the present utility model is now clearly and completely described in the form of specific embodiments in combination with the accompanying drawings.

[0012] Please also see Figure 1 and Figure 2 The motor with a conveniently detachable torque shaft comprises a motor body 1, a motor shaft rear cover 2, a detachable torque shaft 3, a plugging cover 4, a retaining ring 5 and a junction box 6. The junction box 6 is assembled with the motor body 1. The motor shaft rear cover 2 is assembled at the rear end of the motor body 1 through fasteners. The plugging cover 4 and the retaining ring 5 are assembled inside the rear end of the hollow shaft of the motor body 1. One end of the detachable torque shaft 3 is inserted into the hollow shaft of the motor body 1 from the front end of the hollow shaft of the motor body 1. A shearing groove 30 is provided at one end of the detachable torque shaft 3, and a disassembly thread 31 is provided inside the end.

[0013] Torque shaft splines 32 are provided at both ends of the detachable torque shaft 3.
