Motor torque shaft convenient to replace, demount and mount

Abstract

The invention relates to the field of motor parts, in particular to a motor torque shaft convenient to replace, demount and mount. The motor torque shaft comprises a torque shaft body. A first spline in keying fit with a rocker arm is arranged at one end of the torque shaft body. The middle and the other end of the torque shaft body are provided with a second spline and a third spline respectively, wherein the second spline and the third spline are matched with a rotating shaft of a motor. A blind hole is formed in the end of the part, with the third spline, of the torque shaft body, and the axial length of the blind hole is larger than that of the third spline. An annular groove is formed in the position, close to the second spline and at one end of the third spline, on the torque shaft body, a bearing is installed in the blind hole concentric with the bearing, and a pull rod is inserted in an inner ring of the bearing. The motor torque shaft convenient to replace, demount and mount is simple in structure, convenient to operate, flexible in use, high in reliability, convenient to replace and capable of meeting the requirement for safety maintenance in a coal mining machine, and mine production is not influenced.

Description

technical field [0001] The invention relates to the field of motor components, in particular to a motor torque shaft which is easy to replace and disassemble. Background technique [0002] In the prior art, there are many types of motor torque shafts, but most of them have complex structures and different application occasions. Generally, the motor torque shafts installed on the shearer motors have complex structures and many moving parts, making equipment maintenance difficult and costly. High cost and poor reliability. However, when the coal shearer cuts gangue, the resistance is too large, causing the motor torque shaft that plays a protective role to be easily broken. Therefore, it is necessary to research and invent a simple and practical motor torque shaft to solve the complicated problems in the maintenance of mechanical equipment. Contents of the invention [0003] In order to solve many problems existing in the current shearer motor torque shaft, the invention pr...
