Description
Technical field
The utility model belongs to sports equipment technical field, especially relates to a kind of roller bearing abrasion-proof structure.
Background technique
Roller bearing outer ring adopts the full-complement cylinder roller bearing that collar wall is thicker, and the outer diameter face of roller has cylindrical and arc, can coordinate according to use occasion design with roller surface.Utilize this outer ring, roller can directly roll on raceway, and can bear comparatively heavy load and impact load.Common roller bearing, such as V-arrangement roller bearing in use also exists many deficiencies, such as, during use, main strength is at the bottom of the V-shaped groove of roller bearing outer ring, so just make the V-shaped groove bottom land of roller bearing easily and roller surface mutually wear and tear, and make very easily produce noise with the mutual friction of raceway phase in use because roller bearing outer ring mostly is rigid material, and less stable.
In order to solve prior art Problems existing, people have carried out long-term exploration, propose solution miscellaneous.Such as, Chinese patent literature discloses a kind of track roller bearing [application number: 201320188264.5], include outer ring, inner ring and rolling element, described track roller bearing is also closed by clutch shaft bearing and the second bearing and forms, described clutch shaft bearing comprises the first outer ring, the first inner ring and the first rolling element, described second bearing includes the second outer ring, the second inner ring and the second rolling element, and the outer circumferential face of described first outer ring and the second outer ring is combined to form the ring-shaped guide rail groove of indent.Such scheme to some extent solves the problem of existing roller bearing poor stability, but the program still also exists: V-shaped groove bottom land easily and roller surface mutually wear and tear, very easily produce the problems such as noise with the mutual friction of raceway phase during use.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of simple and reasonable, the roller bearing abrasion-proof structure that roller bearing V-shaped groove bottom land not easily weares and teares mutually with roller surface.
For achieving the above object, the utility model have employed following technical proposal: this roller bearing abrasion-proof structure, comprise and be arranged on bearing outer ring outer circumferential and the circular groove caved inward, notch to the bottom land of described circular groove slopes inwardly setting gradually, it is characterized in that, described circular groove bottom land is provided with the annular groove caved inward, roll in described annular groove and be provided with some rolling elements, and annular groove is exposed in described rolling element end, circular groove week is provided with annular rolling ring to the periphery, and described annular rolling ring week to the inside with rolling element mutually against setting.Because annular rolling ring can rotate relative to circular groove circumference, during use, annular rolling ring contacts with roller surface, and annular rolling ring can roll on rolling surface, can prevent the wearing and tearing of this roller bearing like this.
In above-mentioned roller bearing abrasion-proof structure, the cross section of described circular groove is in the V-arrangement with the plane of inclination that two are symmetrically set, and described circular groove and annular rolling ring are all coaxially arranged with bearing outer ring.
In above-mentioned roller bearing abrasion-proof structure, described plane of inclination is provided with annular recess, and described annular rolling ring two ends are respectively against being arranged in annular recess.
In above-mentioned roller bearing abrasion-proof structure, the cross section of described annular groove is circular arc, and the center line of annular groove overlaps with the center line of circular groove.
In above-mentioned roller bearing abrasion-proof structure, described plane of inclination is equipped with some ringwise first flexible projections and the second flexible projection, the first described flexible projection is different from the thickness of the second flexible projection, and the first described flexible projection and the second flexible projection are crisscross arranged one by one.
In above-mentioned roller bearing abrasion-proof structure, and the second flexible projection difference circumference evenly arranges and the first flexible projection is connected with bearing outer ring by position structure with the second flexible projection for the first described flexible projection.
In above-mentioned roller bearing abrasion-proof structure, described position structure comprises some circumferences and is arranged on locating column on plane of inclination, and described locating column inserts in the first flexible projection and the second flexible projection.
In above-mentioned roller bearing abrasion-proof structure, the notch of described circular groove both sides extends to bearing outer ring two ends and forms curved transition sections in outer circumferential, bearing outer ring two ends.
Compared with prior art, the advantage of this roller bearing abrasion-proof structure is: good stability, intensity is high, not easily skidding is there is between roller bearing and raceway during use, stability of rotation, and can prevent from producing noise in using process because annular antislip ring is made up of flexible material, and the wearing and tearing of roller bearing groove can be prevented.
