Abstract
The utility model discloses a kind of pure-rolling bearing, comprise bearing protective cover and bearing main body, described bearing protective cover is by outer ring fixed hole, inner ring fixing threaded hole and outer ring fixing column, cooperation between inner ring fixing column realizes fixing, described outer ring fixed hole and inner ring fixing threaded hole have eight to be uniformly distributed, outer ring fixing column and inner ring fixing column have four to be uniformly distributed, outer ring fixed hole and inner ring fixing threaded hole are not fixed with fixing bolt with the screw of outer ring fixing column and the cooperation of inner ring fixing column, described inner ring is enclosed within the inside of outer ring, and in intermediate gap, be placed with a gear rotor.This pure-rolling bearing, adopt gear rotor to replace the structure of ball and retainer, becoming the original motion combining of sliding and roll is pure rolling, and operation is more stable compared with conventional construction, longer service life, is applicable to and the machinery that kinematic accuracy is had relatively high expectations.
Description
Technical field
The utility model relates to gear technique field, is specially a kind of pure-rolling bearing.
Background technique
Traditional bearing retainer rotates phase mutual friction precision and descends gradually noise-reducing large together with ball, for the gear transmission of some high-precision mechanical devices, traditional gear just can not meet its requirement, replace slip just to can solve this problem if adopting rolls, for this reason, we propose a kind of pure-rolling bearing.
Model utility content
The purpose of this utility model is to provide a kind of pure-rolling bearing, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme: a kind of pure-rolling bearing, comprise bearing protective cover and bearing main body, bearing protective cover comprises bearing protective cover main body, outer ring fixed hole, inner ring fixing threaded hole and gear rotor sliding-groove, bearing main body comprises outer ring, inner ring and gear rotor, described bearing protective cover is by outer ring fixed hole, inner ring fixing threaded hole and outer ring fixing column, cooperation between inner ring fixing column realizes fixing, described outer ring fixed hole and inner ring fixing threaded hole have eight to be uniformly distributed, outer ring fixing column and inner ring fixing column have four to be uniformly distributed, outer ring fixed hole and inner ring fixing threaded hole are not fixed with fixing bolt with the screw of outer ring fixing column and the cooperation of inner ring fixing column, described inner ring is enclosed within the inside of outer ring, and in intermediate gap, be placed with a gear rotor.
Preferably, described bearing main body one side is enclosed construction, and opposite side is to adopt the airtight structure of bearing protective cover.
Preferably, described bearing protective cover is provided with the smooth gear rotor sliding-groove contacting with the terminal end of gear rotor.
Preferably, the internal diameter of described outer ring is than the large 4CM of the internal diameter of inner ring.
Compared with prior art, the beneficial effects of the utility model are: this pure-rolling bearing, adopt gear rotor to replace the structure of ball and retainer, becoming the original motion combining of sliding and roll is pure rolling, operation is more stable compared with conventional construction, longer service life, is applicable to and the machinery that kinematic accuracy is had relatively high expectations.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model bearing protective cover;
Fig. 2 is bearing main body structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-2, the utility model provides a kind of technological scheme: a kind of pure-rolling bearing, comprise bearing protective cover 1 and bearing main body 2, bearing protective cover 1 comprises bearing protective cover main body 11, outer ring fixed hole 12, inner ring fixing threaded hole 13 and gear rotor sliding-groove 13, bearing main body 2 comprises outer ring 21, inner ring 22 and gear rotor 23, described bearing protective cover 1 is by outer ring fixed hole 12, inner ring fixing threaded hole 13 and outer ring fixing column 211, the cooperation that inner ring fixing column is 221 realizes fixing, described bearing main body 2 one sides are enclosed construction, opposite side is the structure that adopts bearing protective cover 1 airtight, described bearing protective cover 1 is provided with the smooth gear rotor sliding-groove 13 contacting with the terminal end of gear rotor 23, described outer ring fixed hole 12 and inner ring fixing threaded hole 13 have eight to be uniformly distributed, outer ring fixing column 211 and inner ring fixing column 221 have four to be uniformly distributed, outer ring fixed hole 12 and inner ring fixing threaded hole 13 are not fixed with the screw fixing bolt that outer ring fixing column 211 and inner ring fixing column 221 coordinate, described inner ring 22 is enclosed within the inside of outer ring 21, and in intermediate gap, be placed with 12 gear rotors 23, the internal diameter of described outer ring 21 is than the large 4CM of the internal diameter of inner ring 22.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned example embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, is therefore intended to all changes that drop in the implication and the scope that are equal to important document of claim to include in the utility model.Any reference character in claim should be considered as limiting related claim.
In addition, be to be understood that, although this specification is described according to mode of execution, but be not that each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should make specification as a whole, and the technological scheme in each embodiment also can, through appropriately combined, form other mode of executions that it will be appreciated by those skilled in the art that.
