Problems solved by technology
[0003] In order to improve the passability of the equipment and the maintainability of the traction motor in the current thin coal seam shearer, the traction motor is installed vertically on the upper surface of the shearer body in the motor housing of the shearer body. This installation method often causes the traction motor to The axial positioning of the shaft is unreliable and easy to loosen, which will lead to the failure of the end face seal of the traction motor after loosening

The invention discloses a coal mining machine traction motor installation structure and a coal mining machine. A machine body of the coal mining machine is provided with a motor shell, a traction motor is installed in the motor shell, the traction motor comprises a first end face and a second end face which are arranged in the axial direction of an output shaft of the traction motor, and the traction motor extends out of the second end face. The motor shell comprises a first inner side face and a positioning component arranged on the first inner side face, the first inner side face corresponds to the first end face, and the positioning component abuts against the first end face so as to apply jacking force to the first end face in the axial direction of the traction motor. The traction motor can be well axially positioned, the positioning is reliable, and the sealing effectiveness of the end face of the traction motor is ensured.
Description
technical field [0001] The invention relates to the technical field of mining equipment, in particular to an installation structure of a coal shearer traction motor and a coal shearer. Background technique [0002] Coal mine underground fully mechanized mining equipment mainly includes hydraulic supports, scraper conveyors and shearers, among which hydraulic supports are used to support the roof; scraper conveyors are used to transport materials, and the pin rails of scraper conveyors provide running tracks for shearers; The fuselage of the shearer is equipped with travel gear, traction motor and rocker arm, the travel gear meshes with the pin rail, and the traction motor is used to drive the travel gear to rotate so that the shearer travels along the pin rail. During the process, the cutter on the rocker drum rotates and cuts the coal seam, and the cut coal is output through the scraper conveyor. [0003] In order to improve the passability of the equipment and the maintai...
