Abstract
The invention discloses a retainer with double curvature special-shaped pockets. The retainer comprises wavy ring retainer body composed by a plurality of pocket portions for accommodating bearing rollers and a plurality of planar ribbon portions which are connected at intervals. The middle part inside of each pocket portion is provided with concentric double curvature large and small spherical zones which concave inward; the inner sides of the pocket portions surrounding the double curvature large and small spherical zones are provided with linear belts; and connecting parts between adjacent two pocket portions and planar ribbon portions are provided with arc-shaped reverse angles. The retainer effectively overcomes the technical problems that a retainer with spherical pockets or ellipsoidal pockets can not work for a long time and have high noise when being operated at a high speed, greatly reduce decibel values and abnormal noise of a bearing, and prolongs the service life of the bearing.
Description
Technical field
The present invention relates to the bearing cage field, specifically a kind of wave-shaped retainer with double curvature special-shaped pocket.
Background technique
At present, the pocket hole of the deep groove ball bearing wave-shaped retainer of domestic production is all spherical or elliposoidal basically.This spherical or spheroid-like, make 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 the pocket hole, but the work that can not work long hours and run up, noise is also higher.
Summary of the invention
The purpose of this invention is to provide a kind of bearing roller that can make and obtain sufficient lubrication in the work that works long hours and run up, reduce the deep groove ball bearing noise, and can not cause the wave-shaped retainer with double curvature special-shaped pocket of the scuffing of deep groove ball bearing rolling element and bearing damage.
Technological scheme of the present invention is as follows:
A kind of retainer with double curvature special-shaped pocket, it is characterized in that: include the waveform ring-type retainer body that the pocket hole section by a plurality of accommodating bearing rollers is connected with a plurality of planes strap interval successively and forms, the middle part of each pocket hole section inboard has respectively and caves inward and the concentric large and small spherical zone of double curvature, inboard around the pocket hole section around the large and small spherical zone of double curvature has respectively the straight line band, and the joint between the strap of Bu Yu plane, adjacent two pocket holes has respectively arc angling.
The described retainer with double curvature special-shaped pocket is characterized in that: on the strap of described a plurality of planes, be respectively equipped with rivet hole.
Beneficial effect of the present invention:
Bearing roller just contacts with the straight line band in the large and small spherical zone outside with large spherical zone in pocket of the present invention 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.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
The B-B that Fig. 2 is Fig. 1 is to sectional drawing;
The A-A that Fig. 3 is Fig. 1 is to sectional drawing.
Embodiment
Referring to accompanying drawing, a kind of retainer with double curvature special-shaped pocket, include the waveform ring-type retainer body that the pocket hole section 1 by a plurality of accommodating bearing rollers is connected with a plurality of planes strap 5 interval successively and forms, the middle part of each pocket hole section inboard has respectively and caves inward and the concentric large and small spherical zone 2,3 of double curvature, inboard around the large and small spherical zone 2,3 of double curvature pocket hole section on every side has respectively straight line band 4, and the joint between the strap of Bu Yu plane, adjacent two pocket holes has respectively arc angling 6.
Be respectively equipped with rivet hole 7 on the strap of a plurality of planes, so that by rivet, two bearing rollers that have special-shaped double curvature pocket hole retainer and be dropped in its pocket hole section that are involutory are linked together.
The present invention and traditional retainer are contrasted, are obtained respectively the correlation test data of the two vibration acceleration and vibration velocity, specifically seen the following form:
By above-mentioned comparative trial data, shown, the present invention has reached the effect that reduces bearing decibel value and different sound fully.
Claims (2)
1. the retainer with double curvature special-shaped pocket, it is characterized in that: include the waveform ring-type retainer body that the pocket hole section by a plurality of accommodating bearing rollers is connected with a plurality of planes strap interval successively and forms, the middle part of each pocket hole section inboard has respectively and caves inward and the concentric large and small spherical zone of double curvature, inboard around the pocket hole section around the large and small spherical zone of double curvature has respectively the straight line band, and the joint between the strap of Bu Yu plane, adjacent two pocket holes has respectively arc angling.
2. the retainer with double curvature special-shaped pocket according to claim 1, is characterized in that: on the strap of described a plurality of planes, be respectively equipped with rivet hole.
