Abstract
The utility model relates to a novel high-speed bearing retainer, which comprises a bearing retainer. The novel high-speed bearing retainer has the following characteristics: each pocket of the bearing retainer is of a concave shape, the four corners of which are circular arc-shaped corners, and the depth of the concave is equal to the radius of a loaded roller. The utility model has the following advantages: in the practical operation of a bearing, the noise-reducing performance of the improved retainer is improved, and after the bearing is mounted, the failure rate of operating disassembly can be reduced.
Description
Technical field
The utility model relates to a kind of bearing cage, particularly a kind of novel high speed bearing cage.
Background technique
Rolling bearing is a mechanical sector application important foundation part very widely, no matter be aircraft, automobile, boats and ships, lathe, or household electric appliance, IT machine etc., every place that rotation is arranged all be unable to do without bearing.Bearing cage is a part of bearing, its main effect: 1, that rolling element is equally spaced, be distributed on the circumference of raceway, and run foul of each other and rub between rolling element when preventing work; 2. guiding and drive rolling element roll on correct raceway; At the 6002 model bearings of my our company, installation is installed and working strength influences on motor, the retainer of bearing is subjected to very big impact force, and when using simultaneously with the high viscosity grease, be easy to cause the retainer noise to increase, frequency vibration changes very greatly in causing.Tackle this problem and design is improved,, reduce the failure rate of bearing on motor to improve the noise reduction sound performance of retainer.
Summary of the invention
The purpose of this utility model is that the retainer that solves the bearing that 6002 model bearings exist in the prior art is subjected to very big impact force, cause the retainer noise easily and cause in the problem of frequency vibration, a kind of novel high speed bearing cage is provided.The utility model designs a kind of novel high speed bearing cage, comprises bearing cage, it is characterized in that: it is the concave shape of arc round angle that the pocket hole of bearing cage is four jiaos, and the degree of depth of concave shape is the radius of institute's dress rolling element.The utility model has the advantages that.Retainer after this improvement mainly is for solving bearing in real work, improve retainer noise reduction sound performance, reduce the failure rate that bearing installation back falsework looses.
Description of drawings
Accompanying drawing is a structure partial schematic representation of the present utility model.
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Embodiment
The retainer of bearing originally easy viscous when bearing operation is lived steel ball, causes the intermediate frequency instability.And the utility model is in order to reduce the amount of contact of steel ball and retainer.Increase the pocket hole shifting amount of retainer, increase the flexibility of steel ball.Increase is to the lubrication of steel ball.
Claims (1)
1, a kind of novel high speed bearing cage comprises bearing cage, it is characterized in that: it is the concave shape of arc round angle that the pocket hole of bearing cage is four jiaos, and the degree of depth of concave shape is the radius of institute's dress rolling element.
