Abstract
The utility model relates to a driving wheel fixing part in an elevator reduction box. A driving wheel comprises a gear-shaped wheel body and a boss which protrudes from one side of the wheel body. A round concave groove is arranged in an axial outer end of the boss, wherein the round concave groove and the wheel body are of the same axis. One side face of the boss of the driving wheel faces a reduction box cover plate. The driving wheel fixing part in the elevator reduction box is characterized by comprising a columnar limiting rod which extends horizontally and is matched with the concave groove and a sheet connecting part which extends longitudinally. According to the driving wheel fixing part in the elevator reduction box, the driving wheel fixing part is independent from the reduction box cover plate, section surface of the limiting rod is small, the abrasion is small and the whole fixing part can be replaced conveniently. A damping structure can be arranged on the outer periphery of the limiting rod. The friction between the driving wheel and the fixing part is reduced, the driving wheel rotates smoothly and the noise is reduced.

For achieving the above object, the technical solution adopted in the utility model is: the drive wheel fixed block in a kind of elevator gear reducer box, described drive wheel comprises the gear shape wheel body and protrudes the boss of wheel body one side, described boss axial outer end is provided with the circular groove coaxial with wheel body, boss one side of described drive wheel is characterized in that to the speed reducer cover plate: comprise the column position-limited lever of horizontal expansion and described groove fit and the sheet joint of longitudinal extension.
In preferred embodiment of the utility model, further comprise the diameter of described position-limited lever less than boss groove internal diameter, the position-limited lever cross-wise direction is mutually on four positions of an angle of 90 degrees along correspondence separately and radially is provided with damping spring.
In preferred embodiment of the utility model, further comprise between the position-limited lever of described drive wheel fixed block and the joint also being provided with the column reinforcing part, described reinforcing part diameter is greater than the position-limited lever diameter.
In preferred embodiment of the utility model, further comprise described position-limited lever, reinforcing part, the coaxial setting of joint, the joint cross-wise direction has four fixed holes that are mutually an angle of 90 degrees, and the circumferential position of described four fixed holes is corresponding one by one with the position of described four damping springs.
In preferred embodiment of the utility model, comprise that further described position-limited lever diameter is 4/5 of described boss groove internal diameter.
In preferred embodiment of the utility model, comprise that further described reinforcing part diameter is spacing shank diameter 3-4 times.
The utility model has solved the defective that exists in the background technique, and drive wheel fixed block of the present utility model is independent of the speed reducer cover plate, and the position-limited lever sectional area is little, weares and teares little, and whole fixed block is changed convenient.Can shock-damping structure be set in the position-limited lever periphery, be conducive to reduce the friction between drive wheel and fixed block, drive wheel be rotated more steady, reduce simultaneously noise.
