Embodiment Construction

[0030] It can be seen from the background art that the installation reliability of the bearing dust cover is low, and the bearing dust cover is easy to fall off.

[0031] It is known that the bearing includes a bearing outer ring, a bearing inner ring, rolling elements, a cage and a bearing dust cover, and the bearing outer ring is provided with a bearing dust cover installation groove, wherein the bearing inner ring is located inside the bearing outer ring, the two The rolling elements limited by the cage are arranged between them, and the bearing dust cover is arranged at both ends of the bearing, and snapped into the bearing dust cover installation groove of the bearing outer ring.

[0032] However, when the bearing dust cover is installed in the bearing dust cover installation groove of the bearing outer ring, the bearing dust cover may not be deformed according to the expected deformation amount, thereby causing the bearing dust cover to fall off.

[0033] In order to sol...

Abstract

The embodiment of the invention provides a bearing and a bearing dust cover. The bearing dust cover comprises a dust cover head, the dust cover head comprises an outer bearing ring contact part in contact with the inner surface of an outer bearing ring, and the outer surface of the outer bearing ring contact part is embossed. According to the bearing and the bearing dust cover, the installation reliability of the bearing dust cover can be improved, and the falling probability of the bearing dust cover can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to the field of mechanical equipment, in particular to a bearing and a bearing dust cover. Background technique [0002] Bearing is an important part of mechanical equipment, which is set between the parts that generate relative rotation. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement and ensure its rotation accuracy. [0003] Rolling bearing is a kind of bearing, including bearing inner ring, bearing outer ring, rolling elements and cage. In order to ensure the cleanliness of the inside of the rolling bearing, prevent the entry of pollutants, and prevent the leakage of grease inside the rolling bearing, there will be a set at the end of the rolling bearing. Bearing dust cover. [0004] However, during use, the bearing dust cover has fallen off, resulting in a decline in the dustproof effect. [0005] Therefore, how to improve the reliab...
