Abstract
Outer lane annular knurl bearing, including bearing inner race, bearing inner race, holder, rolling element and shield, the holder is located between bearing inner race and the bearing inner race, the rolling element is located on the holder, the rolling element takes place to roll and then drives the holder and rotates, in the rotational clearance between holder and bearing inner race, the bearing inner race and the rolling element between rolling interval in all fill and have emollient, the utility model discloses outer lane annular knurl bearing is equipped with on bearing inner race's surface along the recess of circumference extension, and processing has the straight knurling on the recess, has increased the cohesion of plastics with the bearing, has promoted the quality that the bearing was moulded to the package, has prolonged the life of bearing.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of outer ring annular knurl bearing.
Background technique
Bearing rises fixing in mechanical transmission course and reduces the parts of load friction factor, alternatively, when other parts produce relative movement each other on axle, is used for reducing the fixing parts of friction factor in power transmission process and retainer shaft central position.Bearing is a kind of very important component in contemporary machinery.Its major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.
Plastic bearing refers generally to wrap one deck plastics in the outside of bearing, and plastic material is generally nylon PA, polyoxymethylene POM and engineering plastics polypropylene, pp.Outsourcing plastics have certain hardness, anti-impact force, wear-resistingly to examine and certain self-lubricating type.Plastic bearing is the industry of recent domestic new rise, and it is widely used, and in machinery, industrial flow-line, furniture and hardware fitting all has a wide range of applications.The plastic bearing of prior art, have between plastics and bearing in conjunction with illusive phenomenon, can produce relative rotation between plastics and bearing outer ring, affect the normal use of bearing.
Summary of the invention
The purpose of this utility model is the problems referred to above existed for existing plastic bearing, and providing a kind of can increase the outer ring annular knurl bearing of making a concerted effort with plastic tie.
The technological scheme that the utility model solves the problems of the technologies described above and adopts is: outer ring annular knurl bearing, comprise bearing outer ring, bearing inner race, retainer, rolling element and dust cover, described retainer is located between bearing outer ring and bearing inner race, described rolling element is located on retainer, described rolling element occurs to roll and then drive retainer to rotate, described retainer and bearing outer ring, in running clearance between bearing inner race and and rolling element between rolling gap in be all filled with oiling agent, it is characterized in that: the both sides at described bearing outer ring and bearing inner race edge are provided with draw-in groove, dust cover is fastened in this draw-in groove.
As improvement, the outer surface of described bearing outer ring is provided with groove circumferentially, and groove is processed with straight knurling.
As improvement, described rolling element is steel ball, is made up of GCr15 steel.
As improvement, described bearing outer ring and bearing inner race are made by GCr15 steel, the madial wall of described bearing outer ring is provided with the rolling surface for rolling element running, the outer side wall of described bearing inner race is provided with the rolling surface for rolling element running, and the gap between described rolling surface and rolling element is 0.0013-0.002mm.
As improvement, described oiling agent is lubricant oil or lubricating grease, and filling out fat amount is 0.12-0.18g.
Compared with prior art, the utility model has the advantage of: adopt technique scheme, the utility model outer ring annular knurl bearing, the outer surface of bearing outer ring is provided with groove circumferentially, groove is processed with straight knurling, add the combination force of plastics and bearing, improve the quality of plastic bearing, extend the working life of bearing.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
Outer ring annular knurl bearing as described in Figure 1, comprise bearing outer ring 1, bearing inner race 2, retainer 3, rolling element 4 and dust cover 5, described retainer 3 is located between bearing outer ring 1 and bearing inner race 2, described rolling element 4 is located on retainer 3, described rolling element 4 occurs to roll and then drive retainer 3 to rotate, described retainer 3 and bearing outer ring 1, in running clearance between bearing inner race 2 and and rolling element 4 between rolling gap in be all filled with oiling agent, it is characterized in that: the both sides at described bearing outer ring 1 and bearing inner race 2 edge are provided with draw-in groove 11, dust cover 5 is fastened in draw-in groove 11.The outer surface of described bearing outer ring 1 is provided with groove 12 circumferentially, groove 12 is processed with straight knurling 13.Described rolling element 4 is steel ball, is made up of GCr15 steel.Described bearing outer ring 1 and bearing inner race 2 are made by GCr15 steel, the madial wall of described bearing outer ring is provided with the rolling surface 14 for rolling element running, the outer side wall of described bearing inner race is provided with the rolling surface 21 for rolling element running, and the gap between described rolling surface 14,21 and rolling element 4 is 0.0013-0.002mm.Described oiling agent is lubricant oil or lubricating grease, and filling out fat amount is 0.12-0.18g.
The utility model outer ring annular knurl bearing, the outer surface of bearing outer ring is provided with groove circumferentially, groove is processed with straight knurling, adds the combination force of plastics and bearing, improves the quality of plastic bearing, extends the working life of bearing.
Above disclosedly be only a kind of preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
