Description

Technical Field

[0001] The utility model relates to the technical field of bearings, and more specifically to a flange bearing with low friction and noise. Background Art

[0002] In the prior art, the connection and the bearing in some flange bearings are not integrated, and the bearing is installed in the flange by means of interference fit. Therefore, when such flange bearings are subjected to a large impact force, the bearing is easy to move in the connection flange or the bearing ball falls off, or even the entire bearing falls off the connection flange; and such flange bearings are easily affected by dust in the environment, resulting in poor performance; the bearings are easily damaged, and it is inconvenient to replace the flange bearings; when the flange bearings are connected to other flanges, bolts need to be installed diagonally, which is cumbersome.

[0003] The existing patent is a connecting flange used for flange bearings. The patent announcement number CN217873843U solves the problem that the flange bearing is displaced in the connecting flange when it is subjected to a large impact force; solves the problem that the bearing is contaminated by pollutants such as dust in the environment, resulting in a reduced service life and poor performance; solves the problem that the bearing in the flange bearing is difficult to replace and the flange bearing needs to be connected with other flanges. The bolts need to be installed diagonally, which is cumbersome to operate.

[0004] However, the connecting flange in patent announcement No. CN217873843U is divided into an upper end body and a lower end body connected to the upper end body, and the upper end body and the lower end body are fixedly connected by threads. Since the connection by threads is easy to cause the connection part to loosen, the axis between the end bodies and the axis between the end bodies and the bearing cannot be kept on the same axis, resulting in abnormal noise between the components and increasing the friction between the components. Therefore, we propose a flange bearing with low friction noise to solve the above-mentioned problems. Utility Model Content
