Amorphous vertical type shaft bearing

Abstract

The invention relates to an amorphous vertical type shaft bearing. The amorphous vertical type shaft bearing comprises a flange disc, a vertical type shaft, rolling bodies and a machine body, the flange disc is fixedly connected with the vertical type shaft, at least one annular groove concentric with the vertical type shaft is formed in the lower bottom surface of the flange disc, and the cross sections of the annular grooves are in an arc shape. The machine body is provided with a shaft hole for penetrating through the vertical type shaft, at least three hemispherical holes are formed in theperiphery of the upper surface shaft hole of the machine body, the positions of the hemisphere holes correspond to the annular grooves, one rolling body is arranged between each hemisphere hole and the annular grooves of the flange disc, the depth of the annular grooves and the hemispherical holes does not exceed the radius of the rolling bodies and at least one of the the radius of the annular grooves and the hemispherical holes is slightly smaller than the radius of the rolling bodies, and the radius of the arcs of the cross sections of the annular grooves and the radius of the hemispherical holes are equal to the radius of the rolling bodies. The amorphous vertical type shaft bearing has simple structure, can be produced as required, is not limited by models, the cost is low, and the service life is long.

Description

technical field [0001] The present invention relates to bearings, in particular to the internal connection structure of bearings. Background technique [0002] The vertical shaft (the axis line is perpendicular to the ground) as the carrier of power transmission is widely used in all walks of life, especially in the reaction kettle that needs to be stirred in the chemical industry, it is inseparable from the vertical shaft to transmit power. The shaft is inseparable from the bearing when transmitting power, and the shaft must be supported on the body by the bearing. Such as figure 1 As shown, the most common rolling bearing is composed of inner ring a1, outer ring a2, rolling element a3 and cage a4. The outer ring is installed in the bearing housing hole to act as a fixed support; Rotation; the rolling element is the core component of the rolling bearing, which connects the inner ring rotating with the shaft and the outer ring on the fixed frame to transmit power; the cage...

AI Technical Summary

Problems solved by technology

This has caused the following problems: the manufacturer can only use the manufacturer's inherent model, and the model is limited; all bearings have a certain service life; assembly and replacement have high technical requirements and special tools; When it is heavy and the load is heavy, it needs to be customized, the requirements for the bearing are higher, and the price is expensive
