Description

Bearing retainer with oil groove

Technical Field

The utility model relates to a bearing retainer especially relates to a take bearing retainer of oil groove.

Background

The three-row roller type variable pitch bearing of the wind generating set has the basic performances of long service life, low vibration, low noise, small rotating moment, high reliability and the like. After the engineering plastic retainer is assembled, the retainer is completely attached to the rolling body, and lubricating oil can be coated on the rolling body and the retainer before use. During operation, the retainer can bear the combined action of loads such as axial force, radial force, overturning moment and the like, after the bearing works for a period of time, because the raceway and the rolling element are in contact fatigue, abrasion and debris easily occur, and the debris is embedded into the engineering plastic retainer to scratch the rolling element, so that severe scratches of the rolling element are caused, and the service life of the bearing is further influenced.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: in order to overcome the defects existing in the prior art, the utility model provides a bearing retainer with an oil groove.

The technical scheme is as follows: in order to achieve the purpose, the bearing retainer with the oil groove comprises a base body, wherein notches for fixing a bearing roller or a bearing ball are arranged on the base body along the circumferential direction, and a plurality of notches are distributed along the circumferential direction of the base body in an array manner; form the splice bar between two adjacent notches, the splice bar is provided with the oil groove towards the side of notch, the oil groove is extended to radial medial surface by the radial lateral surface of base member.

Furthermore, the oil grooves on the two side faces of the same connecting rib are aligned one by one.

Furthermore, the oil grooves on the two side faces of the same connecting rib are distributed in a staggered mode.

Further, the base body is integrally formed.

Further, the base body is surrounded by a plurality of segments to form a mold.

Further, the oil grooves on the side faces of the adjacent connecting ribs of the adjacent subsections are also distributed in a staggered mode.

Further, the oil groove is arc-shaped.

Further, the base material is POM polyformaldehyde.

The utility model discloses a take bearing holder of oil groove has following technological effect at least:

(1) the oil grooves are formed in the side faces of the connecting ribs of the base body, can increase smoothness of grease, improve lubricating effect, and meanwhile can prevent fragments generated by fatigue wear of the bearing from being embedded into the engineering plastic retainer to scratch the rolling body, so that the service life of the bearing is prolonged;

(2) the scheme provides two oil groove distribution modes, namely alignment distribution and staggered distribution, and compared with alignment oil groove distribution, the grease distributed in a staggered oil groove has higher fluidity;

(3) the crisscross distributed oil groove that this scheme provided can guarantee the intensity of splice bar.

Detailed Description

The principles and features of the present invention will be described with reference to the accompanying fig. 1 to 5, wherein the examples are provided only for explaining the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1, wherein the radially outer side refers to side a and the radially inner side refers to side B.

Example one

A bearing retainer with an oil groove comprises a base body 1 made of POM polyformaldehyde materials. The substrate 1 is surrounded by a plurality of arc-shaped segments 5 to form a circle. The base body 1 is provided with notches 2, the notches 2 are used for mounting bearing rollers or bearing balls, and each notch 2 is correspondingly provided with one bearing roller or bearing ball. The plurality of notches 2 are uniformly distributed in an array along the circumferential direction of the base body 1. Form splice bar 3 before two adjacent notches 2, splice bar 3 is provided with oil groove 4 on the side towards notch 2, oil groove 4 can improve the mobility of grease, and then improves the lubricated effect of whole holder. Specifically, all be provided with many oil grooves 4 on the side of splice bar 3 towards notch 2, the notch 2 of 3 both sides of same splice bar aligns the distribution one by one respectively, oil groove 4 is arc.

Example two

A bearing retainer with an oil groove comprises a base body 1 made of POM polyformaldehyde materials. The substrate 1 is surrounded by a plurality of arc-shaped segments 5 to form a circle. The base body 1 is provided with notches 2, the notches 2 are used for mounting bearing rollers or bearing balls, and each notch 2 is correspondingly provided with one bearing roller or bearing ball. The plurality of notches 2 are uniformly distributed in an array along the circumferential direction of the base body 1. Form splice bar 3 before two adjacent notches 2, splice bar 3 is provided with oil groove 4 on the side towards notch 2, oil groove 4 can improve the mobility of grease, and then improves the lubricated effect of whole holder. Specifically, splice bar 3 all is provided with many oil grooves 4 on the side towards notch 2, and the notch 2 of 3 both sides of same splice bar is crisscross the distribution respectively, and is adjacent oil groove 4 on the 3 sides of the adjacent splice bar of segmentation 5 is also crisscross the distribution. The oil groove 4 is arc-shaped.

Compare embodiment one, the 4 distributions of oil groove of this embodiment alternating-type can make the mobility of grease higher, have better lubricated effect, and can guarantee the intensity of splice bar 3.
