Abstract
Axial fixity 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, this novel axial fixity bearing is provided with the counter sink at bearing inner race, can use the screw to fix the bearing epaxial, prevents axial displacement, and in addition, the shield can prevent that impurity from getting into the bearing, and quantitative emollient and suitable rolling interval can reduce the bleeding of lubricant, have prolonged the life of bearing.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of can the bearing of axial restraint.
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.
Axial restraint between the axle of prior art and bearing, generally all by the position of the shaft shoulder at a rigid bearing, another side is then fixing with nut, lock washer or spring flange etc.This mode is shorter or on axle journal in the inconvenient situation of machining screw at axle, between the two fixing just more difficult.
Summary of the invention
The purpose of this utility model is the problems referred to above existed for existing bearing, provides one can be shorter or on axle journal in the inconvenient situation of machining screw at axle, the axial restraint bearing also can conveniently installed.
The technological scheme that the utility model solves the problems of the technologies described above and adopts is: axial restraint 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, described bearing inner race is provided with counter sink, bearing can be fixed on axle with screw, prevents from moving axially.
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, this novel novel axial rigid bearing, bearing inner race is provided with counter sink, bearing can be fixed on axle with screw, prevents from moving axially, in addition, dust cover can prevent impurity from entering bearing, and bleeding of lubricant can be reduced in quantitative oiling agent and suitable rolling gap, extends 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.
Axial restraint 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.Described bearing inner race 2 is provided with counter sink 21, bearing can be fixed on axle with screw, prevents from moving axially.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 12 for rolling element running, the outer side wall of described bearing inner race is provided with the rolling surface 22 for rolling element running, and the gap between described rolling surface 12,22 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.
This novel novel axial rigid bearing, bearing inner race is provided with counter sink, bearing can be fixed on axle with screw, prevent from moving axially, in addition, dust cover can prevent impurity from entering bearing, and bleeding of lubricant can be reduced in quantitative oiling agent and suitable rolling gap, 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.
