Universal hinge joint assembly of sealed angular contact oscillating bearing steel structure

Abstract

The invention discloses a universal hinge joint assembly of a sealed angular contact oscillating bearing steel structure, and relates to a universal hinge joint of an oscillating bearing steel structure. The universal hinge joint assembly comprises an upper angular contact oscillating bearing, a lower angular contact oscillating bearing, a cross mandrel, a steel casting, a bottom plate, bolts, locating pressing plates and seal rings, wherein the upper angular contact oscillating bearing and the lower angular contact oscillating bearing are provided with inner rings and outer rings; the upper inner ring of the upper angular contact oscillating bearing is tightly matched with one end of the cross mandrel; the upper outer ring of the upper angular contact oscillating bearing is connected with an inner hole of the steel casting in a matching manner; the lower inner ring of the lower angular contact oscillating bearing is tightly matched with one end of the cross mandrel; the lower outer ring of the lower angular contact oscillating bearing is connected with an inner hole of the steel casting in the matching manner; the bottom plate is pressed on the end face of the lower outer ring of the lower angular contact oscillating bearing, parallel and level to the lower end face of the steel casting, and welded with the steel casting; the seal rings are sleeved into the cross mandrel; and the seal rings are located on the steel casting by the locating pressing plates and the bolts to form the universal hinge joint assembly. In engineering application, the steel casting is connected with a member, and the cross mandrel is connected with another member.

Description

technical field [0001] The invention relates to a joint bearing steel structure universal hinge, in particular to a sealed angular contact joint bearing steel structure universal hinge assembly mainly used in steel structure construction projects. Background technique [0002] The steel structure construction project is inseparable from the hinge assembly, but the conventional pin-type hinge joint can rotate freely in one direction, but cannot rotate in other directions, and the stress generated by the rigid structure cannot be eliminated. With the rapid development of society, such nodes can no longer meet the requirements of innovative design and complex force-bearing space structure system, and the connection forms of the structure have become increasingly diversified, requiring certain nodes to have the ability of space rotation and force transmission. characteristic. [0003] Chinese patent CN2937297 discloses a steel structure rod end universal hinge joint device main...
