Description

Technical Field

[0001] The utility model belongs to the technical field of cylindrical roller bearings, and particularly relates to a cylindrical roller bearing with separable end face ribs. Background Art

[0002] A cylindrical roller bearing is a rolling bearing, which mainly consists of an outer ring, an inner ring, cylindrical rollers and a cage. When the shaft rotates, the inner ring rotates accordingly, and the cylindrical rollers roll between the outer ring and the inner ring. Since the rollers are in rolling contact with the inner and outer rings rather than sliding contact, the frictional force is relatively small. The cylindrical roller bearing mainly bears radial loads, that is, the forces perpendicular to the axis of the bearing. At the same time, according to different designs and application scenarios, it can also bear a certain degree of axial load.

[0003] The end face ribs of a cylindrical roller bearing are generally integrally structured with the bearing body, which increases the difficulty and cost during the processing, and is not convenient enough during installation and maintenance. When the components inside the bearing fail and need to be repaired or replaced, the integral end face ribs may hinder the operation, increasing the complexity and time cost of the repair. Therefore, it is necessary to provide a cylindrical roller bearing with separable end face ribs, which can achieve the functions of being easy to process, having a stable installation and being able to be separated conveniently when needed on the premise of ensuring the normal operation of the bearing, improving the production efficiency, reducing the maintenance cost, and meeting the requirements of different industrial application scenarios.

A cage 2 is arranged in the inner cavity of the mounting hole shell 1. A plurality of cylindrical rollers 3 are annularly distributed on the surface of the cage 2. A plurality of embedded holes 7 adapted to the cylindrical rollers 3 are annularly formed on the surface of the cage 2. An outer ring 4 is fixedly connected to the inner cavity of the mounting hole shell 1. The inner wall of the outer ring 4 is in rolling contact with the surface of the cylindrical rollers 3. Ribs 5 are arranged on both sides of the mounting hole shell 1. Mounting assemblies 6 are arranged at the front and rear ends of one side of the ribs 5. The mounting assembly 6 includes limit blocks 61 fixedly connected to the front and rear sides of the ribs 5. Limit slots 62 adapted to the limit blocks 61 are formed at the front and rear ends of both sides of the mounting hole shell 1.

At the same time, the limit locking block 61 is snapped into the inner cavity of the limit slot 62. Then, the user penetrates the screw 64 from one side of the limit locking block 61 to the other side, and threads the screw 64 with the mounting hole housing 1. After the screw 64 is tightened, the retaining edge 5 is stably installed on both sides of the mounting hole housing 1. The cylindrical rollers 3 and the outer ring 4 are limited and protected by the retaining edge 5. Finally, the user snaps the sealing cover 65 into the inner cavity of the circular housing 63 to shield and protect the screw 64 through the sealing cover 65.
