Abstract
The utility model relates to a joint bearing, which comprises a bearing outer ring and an inner ring. The joint bearing is characterized in that an inner edge of the bearing outer ring is provided with an assembling groove, the width of the assembling groove is equal to the thickness of the inner ring, and the height of the assembling groove is equal to the largest outer diameter of the inner ring. An outer edge of the inner ring is provided with a plastic coating. As the outer ring is provided with the assembling groove, the joint bearing is assembled and disassembled conveniently. The outer edge of the inner ring is provided with the plastic coating, and then the joint bearing is fine in wear resistance, long in service life without adding lubricating grease and convenient in using and maintenance.
Description
Technical field
The utility model relates to a kind of bearing, is specifically related to a kind of joint shaft bearing.
Background technique
Normally used joint shaft bearing, by extrusion modling, maintenance is poor; Another is that this structure needs axial restraint in use with the structural type of outer shroud design mix half, uses inconvenient; Also have wear resistance and working life in order to improve joint shaft bearing, normally design has oil groove between the joint shaft bearing inside and outside ring, needs regularly to add lubricant grease in oil groove, otherwise just might damage bearing.So existing joint shaft bearing structure and processing technology complexity, working service is poor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, makes easily, does not need lubricating oil filling fat, and working service is joint shaft bearing easily.
Joint shaft bearing of the present utility model includes outer race and interior ring, it is characterized in that the inner edge of described outer shroud is provided with fitting recess, and the width of fitting recess equates that with the thickness of interior ring the height of fitting recess equates with the maximum outside diameter of interior ring.
In order to realize this purpose better, the outside of described interior ring is provided with plastic coating.
Joint shaft bearing of the present utility model is because outer shroud is provided with fitting recess, and mounting or dismounting are convenient; In plastic coating is arranged on the outside of ring, wear resistance is good, long service life, do not need lubricating oil filling fat, working service convenient.

Embodiment
Joint shaft bearing of the present utility model is made up of outer shroud 2 and interior ring 4, and the outside of interior ring 4 is provided with Ni Fulong plastic coating 1, and the inner edge of outer shroud 2 is provided with fitting recess 3.The width of fitting recess 3 equates that with the thickness of interior ring 4 promptly the width of fitting recess 3 is if choose 30 millimeters, and the thickness of interior ring 4 is also chosen 30 millimeters.The height of fitting recess 3 equates that with the maximum outside diameter of interior ring 4 promptly the height of fitting recess 3 is if get 40 millimeters, and the maximum outside diameter of interior ring 4 is also got 40 millimeters.Ring 4 is laterally packed in the outer shroud 2 in during assembling, and interior ring 4 revolves to turn 90 degrees to working state and gets final product.In ring 4 when outer shroud 2 in, rotating, 2 of outer shrouds contacts with plastic coating 1 on interior ring 4 outsides, plastic coating 1 plays self-lubricating function, the while has also increased the wear resistance of outer shroud 2, the working life of raising bearing.
Claims (2)
1. joint shaft bearing, contain outer race (2) and interior ring (4), it is characterized in that: the inner edge of described outer shroud (2) is provided with fitting recess (3), and the width of fitting recess (3) equates that with the thickness of interior ring (4) height of fitting recess (3) equates with the maximum outside diameter of interior ring (4).
