Knuckle bearing structure

Abstract

The invention relates to a knuckle bearing structure. The knuckle bearing structure comprises an outer ring with a pulling rod, wherein the outer ring is internally provided with an inner ring. The knuckle bearing structure is characterized in that the inner sides of the two ends of the outer ring are respectively provided with a gap; the length of the gap corresponds to the outer diameter of the inner ring; the width of the gap corresponds to the thickness of the inner ring; the inner ring is placed in the outer ring by the gaps; and the outer ring and the inner ring form matched spherical-surface contact. The knuckle bearing structure has the advantages that the inner sides of the two ends of the outer ring are respectively provided with the gap, the length of the gap corresponds to the outer diameter of the inner ring, the width of the gap corresponds to the thickness of the inner ring, the inner ring is horizontally placed in the gaps and is placed into the outer ring by rotation, and the outer ring and the inner ring form matched spherical-surface contact, and since the inner ring is placed into the outer ring by rotation, the separation of the inner ring and the outer ring is conveniently realized, the convenient replacement of the inner ring or the outer ring is realized and the production cost is effectively reduced.

[0002] The joint bearing is a spherical sliding bearing. The basic type is composed of an inner and outer ring with a spherical sliding spherical contact surface. The inner ring and the outer ring are processed and formed at one time. The rod end joint bearing is provided with a pulling rod on the outer ring of the joint bearing. existing see figure 1 , the structure of the rod end joint bearing is composed of an outer ring 1 with an inner spherical surface and a pull rod and an inner ring 2 with an outer spherical surface. Since the rod end joint bearing structure has a pull rod, the inner ring and the outer ring cannot be Processing and forming, the existing structure of the rod end spherical plain bearing is usually to use the basic type of spherical plain bearing embedded in a jacket 3 with a tie rod, or to set the flanging on the outer ring, put the inner ring into the outer ring and then close the flanging, To put the inner ring into the outer ring, because the rod end spherical plain bearing needs to bear a large load, the basic type of spherical plain bearing is embedded in a casing with a tie rod. While ensuring the overall size of the rod end spherical plain bearing, it is bound to It is necessary to reduce the wall thickness of the outer ring, which reduces the radial bearing capacity of the rod end joint bearing; set the flange on the outer ring, put the inner ring into the outer ring and then close the flange to realize the inner ring into the outer ring. In the outer ring, the radial force is small, and the inner ring and the outer ring cannot be separated after forming, and the inner ring or the outer ring cannot be replaced after being damaged, so they have to be scrapped as a whole, which increases the production cost
