A portable joint bearing rolling closing device

Abstract

The invention discloses a portable joint bearing rolling and closing device. The device mainly comprises a positioning base, a rolling head, a tightening nut and steel balls; the positioning base is provided with a boss for fixing a bearing base to guarantee the fixing firmness of the bearing base; the rolling head is a rolling force applying part; a hexagon is designed in middle of the rolling head for conveniently applying force in use; semicircular grooves are designed on the upper and lower surfaces of the rolling head; the groove on the upper surface cooperates with the tightening nut, and the steel ball is placed in the groove, so that the tightening nut is not rotated along with rotation of the rolling head; the groove on the lower surface cooperates with the bearing base, and the steel ball is placed in the groove; and the steel ball achieves the effects of rolling and closing during moving to fix a joint bearing in the bearing base. The device is simple in structure, smaller in part size, low in weight and convenient to carry; and in particular, the portable joint bearing rolling and closing device can achieve preferable effects on outer field operation and repair.

Description

technical field [0001] The invention relates to a closing device, in particular to a portable joint bearing rolling closing device. Background technique [0002] The spherical plain bearing is composed of an inner ring and an outer ring. When the spherical plain bearing is used, the outer ring of the spherical plain bearing needs to be fixed on the bearing seat. The bearing shaft is designed with a V-shaped groove. When installing the joint bearing, it is necessary to close the side of the V-shaped groove on the outer ring of the bearing. [0003] At present, there are two main closing methods. One is to use static pressure, using a press to press one side of the V-shaped groove to deform and flang it, and press it on the outer surface of the bearing to fix the bearing. It is necessary to apply a large external force to make the V-groove flanging by means of static pressure, and a hydraulic press is generally used to realize the application of external force. The hydrauli...

AI Technical Summary

Problems solved by technology

The joint bearing is turned over and closed by the rollers, and the closure is closed by sliding friction, the friction force is large, the wear is fast, the rollers need to be replaced frequently, and the cost is high; and the structure is large, which is not conducive to carrying in field operations
