Problems solved by technology
[0003] The present invention aims at the problem that the existing guide roller bearing assembly and the guide rail have irregular wear marks on the contact part after being used together for a period of time, which affects the running stability of the roller bearing assembly and reduces the guiding accuracy of the guide rail, and provides a guide groove with repaired wear marks. The roller bearing assembly at least includes a roller, a bearing arranged in the roller and an end cover that cooperates with the roller to fix the bearing. And a guide groove that is in multi-point contact with the guide rail, the contact point between the guide groove and the guide rail is A, the center of the guide rail is O, and the guide groove is provided with a wear groove extending inwardly in the direction of the connecting line OA

Abstract
The invention discloses a roller bearing assembly. The roller bearing assembly at least comprises a roller, a bearing arranged in the roller and an end cover matched with the roller to fix the bearing, wherein a guide groove which extends inwards in the radial direction of the roller, is in rolling fit with a guide rail and is in multi-point contact with the guide rail is formed in the outer surface of the roller, the contact point of the guide groove and the guide rail is A, and the circle center of the guide rail is O; and a grinding crack groove extending inwards in the direction of a connecting line OA is formed in the guide groove. Due to the arrangement of the grinding crack groove, the contact area of the roller and the guide rail is increased, wear during rolling fit of the roller and the guide rail is reduced, the guide accuracy is high, and the service life of a product is long.
Description
【Technical field】 [0001] The present application relates to a roller bearing assembly. 【Background technique】 [0002] The roller bearing assembly usually refers to the assembly composed of the bearing and the roller, and the roller with the guide groove and the bearing form the guide roller bearing assembly. The guide grooves of common guide roller bearing assemblies have V-shaped and arc-shaped structures. During operation, the rollers of the assembly and the arc-shaped guide rails are in contact with both sides of the V-shaped groove or the bottom of the arc-shaped groove. After the roller has been used for a period of time, irregular wear marks on the contact parts often appear, which affects the running stability of the roller bearing assembly, reduces the guiding accuracy of the guide rail, and further affects the working accuracy of the supporting mechanical equipment. 【Content of invention】 [0003] The present invention aims at the problem that the existing guide...
