Double-clamping stopper bearing

Abstract

The invention provides a double-clamping stopper bearing comprising an inner ring, an outer ring, a rolling body and a retainer, wherein the rolling surface and the vertical surface of the outer ring are both provided with snap ring grooves; the snap ring groove on each rolling surface and the snap ring groove on the vertical surface which is on the right with 30 degrees of the snap ring groove on each rolling surface form a pair of snap bayonets, and each pair of snap bayonets differs with 30 degrees and simultaneously snap; the shape of the snap ring groove is tetrahedron, sphere or other structures convenient to snap; the snap ring grooves on the rolling surface and the vertical surface can have same figures or different figures. The invention has the obvious effect that the rolling surface and the vertical surface of the outer ring are both provided with the snap ring grooves, and each pair of snap bayonets simultaneously snaps, thus effectively snapping fast operating bearings in time, reducing brake time, and obtaining obvious effect.

Description

technical field [0001] The invention relates to a bearing, in particular to a double-card stop bearing. Background technique [0002] Bearings are fixed parts in machinery. When other parts move relative to each other on the shaft, the parts used to maintain the center position of the shaft and control the movement are called bearings. [0003] In terms of its function, it should be a support, that is, it is used to support the shaft literally, but this is only part of its function. The essence of support is to be able to bear radial loads. It can also be understood that it is used to fix the shaft. It is to fix the shaft so that it can only achieve rotation, while controlling its axial and radial movement. The consequence of a motor without bearings is that it cannot work at all. Because the shaft may move in any direction, and the motor is required to only rotate when it is working. Theoretically speaking, it is impossible to achieve the function of transmission. Not ...

AI Technical Summary

Problems solved by technology

Theoretically speaking, it is impossible to achieve the function of transmission. Not only that, but the bearing will also affect the transmission. In order to reduce this influence, good lubrication must be achieved on the bearing of the high-speed shaft. Some bearings themselves have been lubricated, called pre-lubricated bearings, and Most of the bearings must have lubricating oil. When running at high speed, the friction will not only increase the energy consumption, but what is more terrible is that it is easy to damage the bearings.
