Description

Technical Field

[0001] The utility model relates to the technical field of inner surface grinding of a bearing ring, in particular to a device for grinding the inner surface of a bearing ring. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different friction properties of the moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial dimensions, vibrations and noise are larger, and their prices are also higher. Rolling bearings generally consist of four parts: outer ring, inner ring, rolling element and cage. According to the shape of the rolling element, rolling bearings are divided into two categories: ball bearings and roller bearings.

[0003] However, it is not particularly easy to grind the inner ring of a bearing, because the inner ring is annular in structure, and the inner ring of the bearing itself is easy to rotate during grinding, which brings more inconvenience to the grinding. In addition, the bearing is a precision part, and the fixing of the bearing during grinding is easy to damage the bearing. Therefore, a grinding device is needed that is more convenient for grinding the inner ring of the bearing and less likely to damage the bearing.

[0004] To this end, we propose a bearing ring inner surface grinding device. Utility Model Content
