Abstract
The utility model discloses a low friction deep groove is holder for ball bearing sets up between bearing inner race and bearing inner circle, including the holder body with evenly set up a plurality of pockets on the holder body, the steel ball is installed in the downthehole equal embedding of each pocket, the pocket constitute jointly by sphere region and plane region. The utility model has the advantages that: the bearing friction heat-generating device has the advantage of reducing the bearing friction, and the bearing friction heat-generating is reduced by more than 20%.
Description
Technical Field
The utility model relates to a deep groove ball bearing field, concretely relates to low friction holder for deep groove ball bearing.
Background
Deep groove ball bearings are widely used as rolling bearings due to their advantage of low friction, which is an important indicator of bearings for their frictional properties, friction being the root cause of bearing damage in most cases. The retainer has 6 degrees of freedom in the bearing, and when the bearing operates, the contact friction between the steel balls and the retainer is a main friction source of the bearing. As the bearing speed increases, the fraction of friction becomes higher and higher in the proportion of the total bearing friction.
The shape of the existing cage pocket is designed to be spherical, the radius of the steel ball is close to that of the pocket, the contact area is large, lubricating oil is difficult to enter the contact area of the steel ball and the cage pocket, and the friction between the steel ball and the cage pocket generates heat greatly. The design of the conventional retainer becomes a key factor for restricting the further improvement of the rotating speed of the bearing, the increasingly improved application requirements cannot be met, and how to improve the rotating speed of the bearing needs to be considered from the design level.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a low friction deep groove is holder for ball bearing, change the shape of steel ball and holder pocket contact department into squarely, reduce the area of contact of steel ball and holder pocket, increase the circulation of lubricating oil to reach the purpose that reduces friction.
The purpose of the utility model is accomplished through following technical scheme: the retainer for the low-friction deep groove ball bearing is arranged between a bearing outer ring and a bearing inner ring and comprises a retainer body and a plurality of pockets which are uniformly arranged on the retainer body, a steel ball is embedded into each pocket, and each pocket consists of a spherical area and a planar area.
As a preferable technical scheme, the upper, lower, front, rear and left side surfaces of the pocket contacted with the steel ball are plane areas, and the rest areas of the pocket contacted with the steel ball are spherical areas.
The utility model has the advantages that: the bearing friction heat-generating device has the advantage of reducing the bearing friction, and the bearing friction heat-generating is reduced by more than 20%.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural view of the pocket.
Description of reference numerals: the bearing comprises a bearing outer ring 1, a bearing inner ring 2, a retainer body 3, a steel ball 4, a pocket 5, a spherical area 5-1 and a plane area 5-2.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in the attached drawing, the retainer for the low-friction deep groove ball bearing is arranged between a bearing outer ring 1 and a bearing inner ring 2 and comprises a retainer body 3 and a plurality of pockets 5 uniformly arranged on the retainer body 3, a steel ball 4 is embedded in each pocket 5, and the pockets 5 are formed by a spherical area 5-1 and a plane area 5-2.
As a preferable technical scheme, the upper, lower, front, rear and left side surfaces of the pocket 5 contacted with the steel ball 4 are plane areas 5-2, and the rest areas of the pocket 5 contacted with the steel ball 4 are spherical areas 5-1.
The utility model discloses a working process: the steel ball 4 is arranged in the cage pocket 5, when in use, along with the rotation of the bearing, the bearing inner ring 2 drives the steel ball 4 to rotate, and the steel ball 4 drives the cage body 3 to rotate by pushing the cage pocket 5; the shape of the contact part of the steel ball 4 and the pocket 5 is changed into the combination of a spherical surface and a plane, so that the contact area of the steel ball 4 and the cage pocket 5 can be effectively reduced, lubricating oil easily enters the contact area of the steel ball 4 and the cage pocket 5, and bearing friction is reduced.
Adopt the utility model discloses the structure has effectively reduced the bearing friction. The test shows that under the same condition, the friction heating of the bearing can be reduced by more than 20% compared with the prior structure.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
