Abstract
The utility model discloses a double-curvature deformed pocket hole type retainer which comprises a wave-shaped annular retainer body formed by connecting a plurality of pocket hole parts for containing bearing rolling bodies with a plurality of planar belt-shaped parts at intervals in sequence, wherein small and large double-curvature ball belts which are sunk inwards and concentric are arranged in the middle of the inner side of each pocket hole part; straight-line belts are arranged on the inner sides of the pocket hole parts around the small and large double-curvature ball belts respectively; arc-shaped chamfers are arranged at the joints between two adjacent pocket hole parts and the planar belt-shaped parts respectively. According to the double-curvature deformed pocket hole retainer, the technical difficulty of incapability of working for a long time and high noise during high-speed running, which are hard to overcome by a spherical or elliptic pocket hole type retainer for a long time, are effectively solved; the decibel value and the abnormal noise of bearings are greatly reduced; the service life of the bearings is prolonged.
Description
Technical field
The utility model relates to bearing cage field, specifically a kind of waveform retainer with double curvature special-shaped pocket.
Background technique
At present, the pocket hole of the deep groove ball bearing waveform retainer of domestic production is all spherical or elliposoidal substantially.This spherical or spheroid-like, makes bearing roller can not even can be caused the scuffing of bearing roller by sufficient lubrication when motion, causes bearing short working life, and the noise that bearing produces is high.Also by a little producer, by large spherical zone and straight line band, form pocket hole, but the work that can not work long hours and run up, noise is also higher.
Model utility content
The purpose of this utility model is to provide a kind of bearing roller that can make and obtains sufficient lubrication in the work that works long hours and run up, reduce deep groove ball bearing noise, and can not cause the waveform retainer with double curvature special-shaped pocket of the scuffing of deep groove ball bearing rolling element and bearing damage.
The technical solution of the utility model is as follows:
A kind of double curvature special-shaped pocket retainer, it is characterized in that: include the waveform ring-type retainer body that the pocket hole portion by a plurality of accommodating bearing rollers is connected with a plurality of plane strap successively interval and forms, the middle part of each pocket hole portion inner side has respectively and caves inward and the concentric large and small spherical zone of double curvature, inner side around the large and small spherical zone of double curvature pocket hole portion around has respectively straight line band, and the joint between adjacent two pocket hole portions and plane strap has respectively arc angling.
Described double curvature special-shaped pocket retainer, is characterized in that: in described a plurality of plane strap, be respectively equipped with rivet hole.
The beneficial effects of the utility model:
Bearing roller just contacts with the straight line band in large and small spherical zone outside with large spherical zone in the utility model pocket hole, zona glomerulosa can store grease, be used for guaranteeing that bearing roller has sufficient lubricating, the technical barrier of thereby the retainer that has effectively solved spherical packet hole or elliposoidal pocket hole is difficult to overcome for a long time always can not work long hours and run up work time high noisy, decibel value and the different sound of bearing have been reduced widely, the working life of having improved bearing.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is that the B-B of Fig. 1 is to sectional drawing;
Fig. 3 is the A place enlarged diagram of Fig. 2.
Embodiment
Referring to accompanying drawing, a kind of double curvature special-shaped pocket retainer, include the waveform ring-type retainer body that the pocket hole portion 1 by a plurality of accommodating bearing rollers is connected with a plurality of plane strap 5 successively interval and forms, the middle part of each pocket hole portion inner side has respectively and caves inward and the concentric large and small spherical zone 2,3 of double curvature, inner side around the large and small spherical zone 2,3 of double curvature pocket hole portion around has respectively straight line band 4, and the joint between adjacent two pocket hole portions and plane strap has respectively arc angling 6.
In a plurality of plane strap, be respectively equipped with rivet hole 7, so that two bearing rollers that have special-shaped double curvature pocket hole retainer and be dropped in its pocket hole portion that are involutory are linked together by rivet.
The utility model and traditional retainer are contrasted, obtain respectively the correlation test data of the two vibration acceleration and vibration velocity, specifically see the following form:
By above-mentioned comparative trial data, shown, the utility model has reached the effect that reduces bearing decibel value and different sound completely.
Claims (2)
1. a double curvature special-shaped pocket retainer, it is characterized in that: include the waveform ring-type retainer body that the pocket hole portion by a plurality of accommodating bearing rollers is connected with a plurality of plane strap successively interval and forms, the middle part of each pocket hole portion inner side has respectively and caves inward and the concentric large and small spherical zone of double curvature, inner side around the large and small spherical zone of double curvature pocket hole portion around has respectively straight line band, and the joint between adjacent two pocket hole portions and plane strap has respectively arc angling.
2. double curvature special-shaped pocket retainer according to claim 1, is characterized in that: in described a plurality of plane strap, be respectively equipped with rivet hole.
