Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a high-speed anti-impact engine bearing. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. According to the different friction properties of the moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Engines often also need to use bearings for transmission. Although the engine bearings currently used can meet normal use requirements, they still have defects in actual use. For example, a bearing provided by the authorization announcement number CN209654433U has a simple structure and can prevent the displacement of the outer ring of the bearing after it is connected to the bearing mounting seat. The connection is more secure, which effectively extends the service life of the bearing and is worthy of wide promotion.

[0003] However, the anti-impact effect of this patent is not ideal. During use, the bearing is prone to friction and collision with the connecting parts, which can easily cause serious wear of the bearing over time, thereby causing bearing damage and affecting the service life of the bearing. Therefore, a high-speed anti-impact engine bearing is now proposed. Utility Model Content
