Abstract
The utility model relates to a box of a reduction gear. The box comprises a box body, at least one bearing hole is formed in one side of the box body, the side face, with the bearing hole, of the box body is provided with a baffle for sealing, an annular protection ring is arranged on the inner surface of the bearing hole, the outer side end of the annular protection ring is provided with an annular check ring, and the inner diameter of the annular check ring is identical to that of the annular protection ring. The side face, with the bearing hole, of the box body is provided with the baffle for sealing, the annular protection ring is arranged on the inner surface of the bearing hole, and therefore the service life of the box of the reduction gear is greatly prolonged.
Description
Technical field
The utility model relates to a kind of reduction-gear housing.
Background technique
Common reduction-gear housing bearing hole does not have ring protection cover; after working long hours, be easy to cause bearing hole distortion; cause bearing to produce displacement, and common bearing hole be not around provided for sealing baffle plate, be easy to cause retarder to go wrong.
Model utility content
The technical problems to be solved in the utility model is: for solving the problem of above-mentioned existence, provide a kind of reduction-gear housing, solve short and packing less problem of common reduction-gear housing life-span.
The utility model solves the technological scheme that its technical problem adopts: a kind of reduction-gear housing; comprise casing; casing one side offers at least one bearing hole; casing offers and on bearing hole side, is provided with the baffle plate for sealing; bearing hole internal surface is provided with annular guard ring, and annular guard ring outboard end is provided with the annular retaining ring that inner diameter is identical with annular guard ring inner diameter.
Very close to each other between annular guard ring and bearing hole.
Back-up ring outer diameter is greater than bearing hole inner diameter.
The beneficial effects of the utility model are, reduction-gear housing casing of the present utility model offers the baffle plate and the bearing hole internal surface that on bearing hole side, are provided with for sealing and is provided with annular guard ring, thus working life of prolonged deceleration device case greatly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
