Description

Technical Field

[0001] The present invention relates to the technical field of bearings, and in particular to a novel bearing and an assembly method thereof. Background Art

[0002] In the field of mechanical transmission, cylindrical roller bearings, thanks to their unique structural design, are able to efficiently carry large radial loads and are widely used in various industrial production scenarios. However, with the rapid development of heavy equipment technologies in aerospace, large-scale lifting equipment, and high-end machine tools, the operating conditions of these equipment have placed more stringent demands on the load-bearing performance of bearings. During operation, these heavy equipment not only faces complex and variable radial load impacts, but also must withstand significant axial forces. Due to its inherent structural limitations, a single cylindrical roller bearing cannot meet the requirements of such complex load conditions and often requires the coordinated operation of multiple bearing types such as angular contact ball bearings and tapered roller bearings. While this multi-bearing combination solution can solve the load-bearing problem, it inevitably increases the complexity of equipment assembly and maintenance costs. It also consumes more installation space, restricting the miniaturization and integration of equipment, and becoming a key bottleneck restricting the technological upgrade of heavy equipment.

[0010] Furthermore, a second annular groove is respectively provided on the outer sides of both ends of the inner ring, and the retaining spring is clamped in the second annular groove.

[0011] Furthermore, the roller is rotatably connected to the retaining ring; and / or The split rod is fixedly connected to the retaining ring; or The dividing rod is rotatably connected to the retaining ring.

[0012] According to another embodiment of the present invention, a method for assembling a novel bearing is provided, which is applied to the novel bearing of the previous embodiment and comprises the following steps: S1. Put the outer ring on the inner ring so that one side of the inner ring contacts the inner wall of the outer ring and there is a gap between the other side and the inside of the outer ring. S2. Place the rollers one by one into the gap, then move the inner ring to the center of the outer ring and move the rollers so that they are evenly arranged outside the inner ring. S3.
