Thrust knuckle bearing node

Abstract

The invention relates to a thrust knuckle bearing node. The thrust knuckle bearing node comprises a pin shaft and two thrust knuckle bearings, wherein one end of the pin shaft is provided with a convex ring; the inner rings of the two thrust knuckle bearings are respectively and fixedly sleeved on the pin shaft at the two sides of the convex ring; a bearing seat are sleeved outside the outer ringsof the two thrust knuckle bearings; one end of the bearing seat is provided with limiting mechanisms for limiting the thrust knuckle bearings from moving towards one end of the bearing seat; the other end of the bearing seat is connected with a pressing cover by a locking part with adjustable looseness; the pressing cover is provided with a place-giving hole for extension and swinging of the other end of the pin shaft; the pressing cover is connected with the outer rings of the adjacent thrust knuckle bearings by spacer sleeves; the locking part is used for adjusting the locking force betweenthe pressing cover and the bearing seat to drive the matching between the spacer sleeves and the limiting mechanisms so as to loosen and tighten the outer rings and the inner rings of the thrust knuckle bearings and realize switching of the thrust knuckle bearings between the hinging connection and rigid connection. The thrust knuckle bearing node has the advantages that the design is reasonable,the adjustment is simple and convenient and free switching between hinging connection and rigid connection can be achieved.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a thrust joint bearing node. Background technique [0002] Joint bearing is a kind of spherical sliding bearing, which is mainly composed of an outer ring with an inner spherical surface and an inner ring with an outer spherical surface. The outer ring and the inner ring can rotate relative to each other to form a hinge, and have a large load capacity. Impact resistance, corrosion resistance, wear resistance, self-aligning, good lubrication and other characteristics. The traditional thrust joint bearing nodes are usually set up in pairs, and the articulation cannot be switched to a rigid connection. Contents of the invention [0003] The object of the present invention is to address the shortcomings of the prior art and provide a thrust joint bearing node with a reasonable design, a simple structure, and the ability to switch from hinged joints to rigid joints. [0004] To a...
