Description

Joint bearing

Technical Field

The utility model relates to a joint bearing.

Background

The joint bearing is a spherical sliding bearing, which is commonly used for swinging motion at low speed, rotating motion and tilting motion within a certain angle range, and generally comprises an inner ring and an outer ring, wherein the inner ring and the outer ring are respectively provided with an outer spherical surface and an inner spherical surface which can be in sliding abutting fit, and the sliding abutting of the outer spherical surface and the inner spherical surface forms a certain angle rotating swing between equipment parts connected with the inner ring and the outer ring.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects in the prior art, the utility model provides the joint bearing with larger adjustment range.

In order to achieve the purpose, the utility model provides a joint bearing which comprises an outer ring and an inner ring, wherein a first inner spherical surface is arranged on the outer ring, a first outer spherical surface is arranged on the inner ring, the first inner spherical surface and the first outer spherical surface are in sliding butt joint, the joint bearing also comprises a protective shell, the protective shell is in sleeve fit with the outer ring, a second inner spherical surface is arranged on the protective shell, a second outer spherical surface is arranged on the outer ring, the second inner spherical surface and the second outer spherical surface are in sliding butt joint, and a stud forming rotary connection of the protective shell and the outer ring is arranged between the protective shell and the outer ring in a penetrating mode.

The technical scheme has the advantages that: through setting up and cup joint the complex protective housing with the outer lane, and set up sphere and the second outer sphere of the second of slip butt between outer lane and protective housing, make can relative activity between outer lane and the protective housing, and set up between protective housing and the outer lane and constitute both and rotate the bolt post of connecting then can inject the relative rotation who uses the bolt post as the axis with both range of motion, and the regulation bolt post is worn the point and just can be adjusted the injecing to protective housing and outer lane range of motion, when increase joint bearing amplitude of regulation promptly, can also be according to the scene needs, through the regulation bolt post position, adjust the range of regulation, on the other hand can guarantee the stable connection between protective housing and the outer lane.

The utility model may further be arranged to: the bolt column comprises a cap part, a threaded part and a front part, the cap part can be abutted and limited with the peripheral wall of the protective shell, the threaded part is threaded on the protective shell, and the front part is rotatably inserted on the second outer spherical surface of the outer ring.

Through further setting up, the embolus includes cap portion, spiro union portion and anterior, constitutes location between them by the spiro union cooperation between spiro union portion and the protective case to it is spacing to the whole degree of stretching into of embolus by butt between cap portion and protective case, later by rotating between anterior and the outer lane insert establish, thereby make the normal running fit between protective case and the outer lane.

The utility model may further be arranged to: the front part is arranged to be gradually reduced, and a conical groove for inserting the front part is formed in the second outer spherical surface of the outer ring.

Through further setting up, adjust the holistic degree of stretching into of embolus, can be through from butt to interference butt between front end and the taper groove to progressively strengthen the magnitude of interference, adjust the frictional force between embolus and the outer lane, adjust the relative rotation between protective housing and the outer lane and need exert the force.

The utility model may further be arranged to: the periphery wall department of outer lane be provided with the elasticity gasket, the elasticity gasket cup joint on the bolt and with the cap between the elasticity butt.

Through further setting, at the progressively in-process that gos deep into of embolus, the elastic gasket deformation power between cap portion and the outer lane strengthens, avoids between anterior and the outer lane frictional force too big, leads to the rotatory problem of embolus to take place.

The utility model may further be arranged to: the first inner spherical surface of the outer ring is provided with mounting grooves at two ends, and the distance between the two mounting grooves is equal to the diameter length of the inner ring.

Through further setting up, set up the mounting groove, be convenient for pack the inner circle into among the outer lane.
