Description

A kind of shield bearing
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of shield bearing.
Background technique
Bearing is a kind of very important component in machinery, at mechanical field, be used widely, it and axle are used in conjunction with the motion that can supported mechanical solid of rotation rotates in a circumferential direction, in mechanical transmission course, not only can play fixation, and can reduce load friction factor, reduce resistance to motion, reduce wear.When other parts produce relative movement each other on axle, friction factor and retainer shaft central position that bearing can be used to reduce in power transmission process are fixed.A lot of bearings need the working environment long time running that environment is severe, dust is larger, easily wearing and tearing, avoid outside the ball of bearing is directly exposed to, the working life that prevents entering dust and can effectively improve bearing, a lot of designers have set up dust cover on bearing, avoid by dust, being invaded in ball.
China patent CN 202348987 U disclose a kind of shield bearing, this shield bearing mainly comprises bearing outer ring, bearing inner race and steel ball, between bearing outer ring and bearing inner race, arrange several steel balls, bearing outer ring dustproof groove is all offered in the both sides of the inner headed face of bearing outer ring, between bearing outer ring and bearing inner race, arrange dust cover, the edge of dust cover arranges groove, and groove snaps in the bearing outer ring dustproof groove of bearing outer ring.The bearing that installs dust cover additional can effectively avoid the dust of job site to enter bearing inside at the construction field (site), thereby has avoided the inner stuck point phenomenon of bearing.
But the dust cover clamping in above-mentioned patent is not firm, easily come off, and leave larger gap between dust cover and retainer, still have dust and enter bearing is caused to wearing and tearing, this dustproof cover structure is firm not in addition.
Summary of the invention
The problems referred to above that the utility model exists for existing technology, provide a kind of shield bearing, and technical problem to be solved in the utility model is: how by improving the intensity of bearing sealed ring, thereby improve the sealability of seal ring.
The object of the invention can realize by following technical proposal:
A kind of shield bearing, described bearing comprises bearing inner race and bearing outer ring, between described bearing inner race and bearing outer ring, be provided with some balls, between described bearing inner race and bearing outer ring, be also provided with the retainer for keeping ball position, it is characterized in that, the internal surface of described bearing outer ring is provided with draw-in groove one, the outer surface of described bearing inner race is provided with draw-in groove two, described bearing also comprises seal ring, the outer periphery of described seal ring and inner periphery respectively with described draw-in groove one and draw-in groove two interference fit, described seal ring forms a fold projection by flanging.
Its principle is as follows: in the utility model, seal ring outer periphery is connected in draw-in groove one, seal ring inner periphery is connected in draw-in groove two, bearing is played to good seal action, prevent that dust from entering in ball and retainer, the wearing and tearing of dust to ball have been avoided entering in ball and retainer, greatly improved the working life of bearing, the outer periphery of seal ring and inner periphery respectively with draw-in groove one and draw-in groove two interference fit, make sealability better, can also anti-sealing or other liquid enter bearing inside, ball and retainer are caused to corrosion; Seal ring forms a fold projection by flanging, can increase the bulk strength of seal ring, and makes the connective stability of seal ring and bearing better, avoids seal ring to come off from bearing, and then improves the anti-dust performance of seal ring.
In above-mentioned a kind of shield bearing, described draw-in groove one, draw-in groove two and seal ring are to be symmetrical two groups along described ball distributing line, and described ball and retainer are all positioned at the space that described bearing inner race, bearing outer ring and seal ring form.Near the bearing surface wind of outer end, easily enter dust under normal circumstances, but whole ball and retainer are sealed with two groups of seal rings, can make ball and retainer be isolated from the outside out completely, dust-proof effect is better, and bearing can adapt to more complicated and rugged environment like this.
In above-mentioned a kind of shield bearing, in the confined space that described seal ring forms, be marked with lubricant oil.The bearing inner race of bearing and bearing outer ring relative movement, ball runs up, and frictional force is the smaller the better, increases lubricant oil, can play lubrication effect, reduces friction, and reduces wear, and improves the working life of bearing.
In above-mentioned a kind of shield bearing, on the outer periphery of described seal ring and inner periphery, be also provided with flange, described draw-in groove one and draw-in groove two edges are provided with flange, and described flanging is resisted against on described boss.In the junction on limit, two ends, easily exist gap that dust is entered, increase boss and flanging, increased area of contact, flanging end socket place stress distribution more rational, level and smooth, and avoid occurring crack in stress compare great district, simultaneously more firm.
In above-mentioned a kind of shield bearing, described seal ring adopts silicone rubber to make.Silicone rubber has certain elasticity and hardness, effective with the interference fit seal of bearing shaft bearing outer-ring and bearing inner race, and supporting effect is strong, can resist certain extraneous impact force.
In above-mentioned a kind of shield bearing, described retainer adopts stainless steel to make.Stainless steel hardness is high, not easy to wear, be difficult for getting rusty, and smooth skin friction is little.
Compared with prior art, the utlity model has following advantage:
1, in this bearing the outer periphery of seal ring and inner periphery respectively with draw-in groove one and draw-in groove two interference fit, good sealing effect.
2, in this bearing, the interface of seal ring and bearing inner race and bearing outer ring goes out to be provided with boss and flanging, has increased area of contact, flange end socket place stress distribution more rational, level and smooth, and avoid occurring crack in stress compare great district, simultaneously more firm.
3, in this bearing, seal ring is provided with the fold projection towards ball, gains in strength.
