Description
Technical field
The utility model relates to a kind of bearing, specifically a kind of outer ring annular knurl bearing belongs to technical field of bearings.
Background technique
Plastic bearing refers generally to wrap one layer of plastics outside bearing, and plastic material is usually nylon, polyformaldehyde and work
Engineering plastics polypropylene etc..Outsourcing plastics have certain hardness, the certain self-lubrication of anti-impact force, antifriction scrape along.Plastic axis
Holding is the recent domestic industry newly risen, and is widely used, on mechanical equipment, industrial flow-line, furniture and Hardware fitting all
It has a wide range of applications.
The plastic bearing of the prior art, due to the rubbing action between covered plastics layer and belt, operational process can generate friction
Heat softens covered plastics layer, and covered plastics layer is caused to produce relative sliding with bearing outer ring, can generate between plastics and bearing outer ring opposite
Rotation, influences bearing service life.
Summary of the invention
In place of the purpose of this utility model is to overcome above-mentioned deficiency, so that providing one kind can increase and plastics binding force
Outer ring annular knurl bearing prolonged the service life with improving bearing arrangement intensity.
According to technical solution provided by the utility model, a kind of outer ring knurled shaft, which is contracted, includes bearing outer ring, bearing inner race, steel
Ball, retainer and sealing ring, bearing inner race are arranged concentrically in bearing outer ring, are equipped between bearing inner race and bearing outer ring multiple
For positioning the retainer of each steel ball, multiple circumferentially equally distributed ball installations are equipped in each retainer
Chamber rolls one steel ball of installation in each ball installation cavity, it is characterized in that: the bearing outer ring external peripheral surface is equipped at least
One annular groove being circumferentially distributed, annular groove center are equipped with annular knurl.
Further, retainer two sides are respectively equipped with sealing ring, and the Internal and external cycle of sealing ring is respectively and outside bearing inner race, bearing
Circle interference fit, so that sealing ring is in impaction state.
Further, annular groove is two.
Further, annular knurl is straight knurling.
Compared with the prior art the utility model has the advantage that
The utility model structure is simple, compact, reasonable, and circumferentially recessed is equipped on the outer surface of bearing outer ring
Slot is machined with straight knurling on groove, increases the binding force of plastics and bearing, improve the quality of plastic bearing, extend
The service life of bearing.
Detailed description of the invention
Fig. 1 is the utility model main view.
Description of symbols: 1- bearing outer ring, 2- bearing inner race, 3- steel ball, 4- retainer, 5- sealing ring, 6- annular groove, 7-
Annular knurl.
Specific embodiment
The utility model will be further described in conjunction with the embodiment in attached drawing below:
As shown in Figure 1, the utility model mainly includes bearing outer ring 1, bearing inner race 2, steel ball 3, retainer 4 and sealing ring
5。
Bearing inner race 2 is arranged concentrically in bearing outer ring 1, is equipped between bearing inner race 2 and bearing outer ring 1 multiple for fixed
The retainer 4 of each steel ball 3 in position, each retainer 4 is interior to be equipped with multiple circumferentially equally distributed ball installation cavitys, often
One steel ball 3 of installation is rolled in a ball installation cavity.
4 two sides of retainer are respectively equipped with sealing ring 5, the Internal and external cycle of sealing ring 5 respectively with bearing inner race 2,1 mistake of bearing outer ring
It is full of cooperation, so that sealing ring 5 is in impaction state.
In order to improve the binding force of bearing outer ring and covered plastics layer, 1 external peripheral surface of bearing outer ring is equipped at least one
A annular groove 6 being circumferentially distributed, 6 center of annular groove are equipped with annular knurl 7, and the annular knurl 7 is straight knurling.
In embodiment as shown in Figure 1, the annular groove 6 is two.
The utility model structure is simple, compact, reasonable, and circumferentially recessed is equipped on the outer surface of bearing outer ring
Slot is machined with straight knurling on groove, increases the binding force of plastics and bearing, improve the quality of plastic bearing, extend
The service life of bearing.
