Rod end spherical plain bearing structure

Abstract

The invention provides a rod end spherical plain bearing structure. Through the use of the structure, external dimensions of the whole rod end spherical plain bearing and wall thickness of an outer ring are ensured at the same time, the bearing capacity of the rod end spherical plain bearing is improved, the separation of an 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. The structure comprises the outer ring with a pull rod, and the inner ring is arranged in the outer ring; and the structure is characterized in that breaches are respectively formed in the inner sides of the both ends of the outer ring, the length of the breaches and the outer diameter of the inner ring are corresponding, the width of the breaches and the thickness of the inner ring are corresponding, the inner ring is put into the outer ring through the breaches, and anastomotic spherical contact is formed between the outer ring and the inner ring.

Description

technical field [0001] The invention relates to the technical field of bearing manufacture, in particular to a rod end joint bearing structure. Background technique [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 pull rod, or ...

[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 pull 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
