Fixing device facilitating surface treatment of outer-ring side surface of bearing

Abstract

The invention discloses a fixing device facilitating surface treatment of the outer-ring side surface of a bearing. The fixing device comprises a fixed seat, wherein a fixed support is arranged on the fixed seat; a rotating shaft is arranged on the fixed support; a gear is arranged on the rotating shaft in a sleeving manner; a rotating handle is arranged at one end of the rotating shaft; a limit bar is arranged on the fixed seat in a penetrating manner; a plurality of sawteeth are formed at the lower end of the limit bar and meshed with the gear; the bearing is arranged on the limit bar in a sleeving manner; an elastic support mechanism is arranged on the inner ring of the bearing and consists of an upper support block, a spring and a lower support block; and the spring is positioned between the upper support block and the lower support block. The fixing device can effectively fix the bearing with an appropriate fixing force, can well meet bearing fixing demands during treatment of the outer-ring side surface of the bearing, is low in cost and convenient to operate, can adapt to bearings of different sizes, greatly improves the outer-ring side surface treatment efficiency of the bearing, and therefore, is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of bearing production equipment, in particular to a fixing device for surface treatment on the side surface of a bearing outer ring. Background technique [0002] Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, they are used to reduce the friction coefficient during power transmission and maintain the center position of the shaft. fixed parts. Bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of mechanical load during the transmission process of the equipment. According to the different friction properties of moving elements, bearings can be divided into rolling bearings and sliding bearings. The side of the bearing outer ring must undergo surface...

AI Technical Summary

Problems solved by technology

The side of the bearing outer ring must undergo surface treatment before leaving the factory. Special tools are usually required to fix the bearing when the side of the bearing outer ring is surface treated, but the fixing effect of the existing tools does not meet the fixing requirements of the surface treatment. The cost is high, the use is inconvenient, and it cannot be adapted to bearings of different sizes, so that the surface treatment efficiency of the side surface of the outer ring of the bearing is low
