Abstract
The present invention relates to a kind of bearing, specifically a kind of outer ring annular knurl bearing belongs to technical field of bearings.It includes bearing outer ring, bearing inner race, steel ball, retainer and sealing ring, and bearing outer ring external peripheral surface is equipped at least one annular groove being circumferentially distributed, and annular groove center is equipped with annular knurl.The invention has the advantages of simple structure, compactness and reasonable structure, and groove circumferentially is equipped on the outer surface of bearing outer ring, straight knurling is machined on groove, increases the binding force of plastics and bearing, improve the quality of plastic bearing, extend the service life of bearing.
Description
Technical field
The present invention relates to a kind of bearing, specifically a kind of outer ring annular knurl bearing belongs to technical field of bearings.
Background technology
Plastic bearing refers generally to the outside packet last layer plastics in bearing, and plastic material is usually nylon, polyformaldehyde and work
Engineering plastics polypropylene etc..Outsourcing plastics have certain hardness, the certain self lubricity of anti-impact force, antifriction scrape along.Plastic axis
It is the recent domestic industry newly risen to hold, 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 will produce friction
Heat makes covered plastics layer soften, and covered plastics layer is caused to be produced relative sliding with bearing outer ring, will produce between plastics and bearing outer ring opposite
Rotation, influences bearing service life.
Invention content
It is an object of the present invention to overcome the above deficiencies, to provide it is a kind of can increase it is outer with plastics binding force
Circle annular knurl bearing is prolonged the service life with improving bearing arrangement intensity.
According to technical solution provided by the invention, a kind of outer ring knurled shaft contract include bearing outer ring, bearing inner race, steel ball,
Retainer and sealing ring, bearing inner race are arranged concentrically in bearing outer ring, and multiple use are equipped between bearing inner race and bearing outer ring
In the retainer for positioning each steel ball, each retainer is interior to be equipped with multiple circumferentially equally distributed ball installation cavitys,
One steel ball of installation is rolled in each ball installation cavity, it is characterized in that：The bearing outer ring external peripheral surface is equipped at least one
A annular groove being circumferentially distributed, annular groove center are equipped with annular knurl.
Further, retainer both sides are respectively equipped with sealing ring, the Internal and external cycle of sealing ring respectively with 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 present invention has the following advantages：
The invention has the advantages of simple structure, compactness and reasonable structure, is equipped with groove circumferentially on the outer surface of bearing outer ring, on groove
It is machined with straight knurling, increases the binding force of plastics and bearing, improves the quality of plastic bearing, extends the use of bearing
Service life.
Description of the drawings
Fig. 1 is front view of the present invention.
Reference sign：1- bearing outer rings, 2- bearing inner races, 3- steel balls, 4- retainers, 5- sealing rings, 6- annular grooves, 7-
Annular knurl.
Specific implementation mode
The present invention will be further described in conjunction with the embodiment in attached drawing below：
As shown in Figure 1, the invention mainly comprises bearing outer ring 1, bearing inner race 2, steel ball 3, retainer 4 and sealing rings 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 in position 3 is equipped with multiple circumferentially equally distributed ball installation cavitys in each retainer 4, often
One steel ball 3 of installation is rolled in a ball installation cavity.
4 both 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 the 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 invention has the advantages of simple structure, compactness and reasonable structure, and groove circumferentially is equipped on the outer surface of bearing outer ring, recessed
It is machined with straight knurling on slot, increases the binding force of plastics and bearing, improves the quality of plastic bearing, extends bearing
Service life.
