Abstract
This utility model relates to a kind of bearing preventing sealing member circumference from skidding, and it includes, inner ring and outer ring, the annular housing formed between inner ring and outer ring；It is characterized in that: it also includes dust cap, dust cap has sealing ring, is provided with a milling one R groove on the sealing kerve of corresponding bearing；Arranging a stop edge on corresponding sealing ring external diameter on sealing ring, stop edge matches with R groove.This patent uses and carries a stop edge on dust cap or sealing ring external diameter, and milling one R groove in bearing seal groove bottom makes stop edge prevent sealing member circumferential slippage in being stuck in R groove after assembling, the method facilitates feasible.
Description
Technical field
This utility model relates to a kind of bearing, is related specifically to a kind of bearing with sealing ring.
Background technology
Bearing sealed ring, a kind of bearing seal, especially a kind of ball bearing, ball bearing sealing ring is at annular
An end face on upwardly extend two conglobate projections, protruding internal diameter that described diameter is less and ball bearing
Inner ring external diameter matches, and the described projection being relatively large in diameter matches with the ball circle external diameter of ball bearing；Described sealing ring
Internal orifice dimension not less than the internal orifice dimension of ball bearing inner ring.Have and prevent that oils and fats is on fire, avoid often refueling and simple in construction etc.
Feature.In the prior art, some bearing, because using bad environments, particularly in the environment of dust is relatively big, then needs close
Seal；Sealing ring is all arranged between inner ring and outer ring, owing to using for a long time, abrasion, often causes sealing ring
The phenomenon such as aging, deforming aging rear sealing ring can rotate along with the rotation of bearing.So time length, the most just loses sealing
Effect.
Summary of the invention
The purpose of this utility model is: provides a kind of bearing preventing sealing member circumference from skidding, allows bearing no matter use many
For a long time all without occurring in the phenomenon skidded on race ring.
For completing foregoing invention purpose, this utility model is achieved in that a kind of axle preventing sealing member circumference from skidding
Holding, it includes, inner ring and outer ring, the annular housing formed between inner ring and outer ring；It is characterized in that: it also includes dust-proof
Lid, dust cap has sealing ring, is provided with a milling one R groove on the sealing kerve of corresponding bearing；On sealing ring, correspondence is close
Arranging a stop edge on seal external diameter, stop edge matches with R groove.Structure of the present utility model is designed with the stop of sealing ring
Limit and coordinating of sealing kerve, thus prevent sealing ring and slide.
Being improved further above-mentioned technical scheme, described sealing ring is step-like, dust cap and sealing ring phase
Corresponding in scalariform；The getting out of a predicament or an embarrassing situation of dust cap is pressed on the topping bar of sealing ring.Described sealing ring bore part is toed-out.
This patent uses and carries a stop edge on dust cap or sealing ring external diameter, milling one R groove in bearing seal groove bottom,
Making stop edge prevent sealing member circumferential slippage in being stuck in R groove after assembling, the method facilitates feasible.
Accompanying drawing explanation
Fig. 1 is the full schematic diagram of knot of this sealing ring and dust cap.
Fig. 2 is the schematic diagram that sealing ring engages with R groove.
Detailed description of the invention
For further description feature of the present utility model, below in conjunction with the accompanying drawings this product is made further
Bright:
As it can be seen, a kind of bearing preventing sealing member circumference from skidding, it includes, inner ring and outer ring, in inner ring and outer ring
Between the annular housing that formed, it also includes that dust cap 2, dust cap 2 have sealing ring 1, at the bottom of the seal groove of corresponding bearing
Face 3 is provided with a milling one R groove 31；Sealing ring 1 arranges on corresponding sealing ring 1 external diameter a stop edge 11, stop edge and R groove
Match.Structure of the present utility model is designed with the stop edge of sealing ring 1 and coordinating of sealing kerve, thus prevents sealing ring
1 slides.Described sealing ring 1 in step-like, dust cap 2 corresponding with sealing ring 1 in scalariform；The pressure of getting out of a predicament or an embarrassing situation of dust cap 2
On the topping bar of sealing ring 1.Described sealing ring 1 bore part is toed-out.
Bearing dustproof cover 2, sealing ring 1 is used in traditional product, simple in construction, easy for installation and practical, but assembling
Rear sealing member easily circumferentially slides in groove, easily loosens, falls lid after using a period of time, and impact is normal to be used.And this is specially
Profit carries a stop edge on dust cap 2 or sealing ring 1 external diameter, and in bearing seal groove bottom 3, milling one R groove 31, only makes after assembling
Dynamic checkpost prevents sealing member circumferential slippage in R groove, and the method facilitates feasible.
Claims (3)
1. preventing the bearing that sealing member circumference skids, it includes, inner ring and outer ring, the ring formed between inner ring and outer ring
Shape cavity；It is characterized in that: it also includes dust cap, dust cap has sealing ring, milling on the sealing kerve of corresponding bearing
