Abstract

The invention belongs to the technical field of bearings, and in particular relates to a cylindrical roller bearing, which includes an outer ring, an inner ring and several rollers. There are flanges extending outward at both ends, and the inner ring has a shaft hole. The shaft hole of the inner ring passes through the flange along its axis direction, and the inner peripheral surface of the flange is provided with an arc-shaped groove communicating with the shaft hole. , the arc-shaped groove is slidingly provided with a matching arc-shaped plate, the inner surface of the arc-shaped plate is fixed with an arc-shaped rubber block, and the arc-shaped plate is pushed by tightening the locking screw, and the arc-shaped rubber block is held against On the rotating shaft, so as to realize the axial fixation of the bearing on the rotating shaft, wherein, the arc-shaped plate can evenly set off the arc-shaped rubber block, so that the arc-shaped rubber block can better touch the rotating shaft, and the contact between the arc-shaped rubber block and the rotating shaft The large area allows the bearing to be axially positioned on the rotating shaft more reliably.

Description

technical field [0001] The invention belongs to the technical field of bearings, in particular to a cylindrical roller bearing. Background technique [0002] Cylindrical roller bearings are often used in large and medium-sized electric motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, vibrating screens, and lifting and transportation machinery. For positioning, additional axial positioning components such as bearing housings, positioning sleeves, etc. are required, which makes the assembly of the bearings on the rotating shaft more cumbersome and complicated. Contents of the invention [0003] In order to solve the problem that the bearing itself cannot achieve axial positioning in the prior art, a cylindrical roller bearing is now provided. [0004] In order to achieve the above object, the technical solution adopted by the present invention is, a cylindrical roller bearing, including an outer r...
