Description
Technical field
The utility model relates to a kind of bearing sealed ring, especially a kind of rubber structure bearing seal check ring.
Background technique
Needle roller need to be kept more flexible to a large amount of lubricating grease is added between its outer ring and inner ring when needle bearing use
Ground rotation, and needle roller can generate axial motion in rotation, cause partial lubrication rouge can by related spilling, after rotating for a long time,
Lubricating grease can be reduced constantly, be reduced to the lubricating ability of needle roller, make the increased friction of needle roller Yu outer ring, interior interannular, and extraneous
Dust impurity is also easily accessible in needle bearing, leads to inordinate wear, so as to shorten the service life of needle bearing.
To solve the problems, such as that needle bearing lubricating grease overflows and extraneous dust impurity enters, it is common that in needle bearing two sides
It jumps a queue rubber seal.However, current rubber seal coil structures are single, needle bearing is opened when stopping operating by the condition of high temperature
Begin to cool down, its internal generation vapour lock can be made, and current rubber seal bearing capacity is weaker, not only will increase seal clearance makes
Sealing performance decline, and root can be accelerated chew to reduce the service life.
Summary of the invention
The purpose of this utility model is to provide a kind of rubber structure bearing seal check rings, it improves rubber by reinforcing ring
The bearing capacity of sealing ring body, prolongs the service life, and sealing lip can effectively inside and outside two way seal, effect be more preferable.
Realize above-mentioned purpose, the utility model takes following technical proposals: a kind of rubber structure bearing seal check ring, including
Rubber seal ontology and reinforcing ring, the rubber seal ontology shape are annular shape, rubber seal outer body end
Face is coaxially recessed with annular groove, and the reinforcing ring insertion is fixed in the annular groove, rubber seal ontology outer ring surface with it is interior
Side end face intersection location rounding off, rubber seal ontology inner ring surface are equipped with sealing lip, the sealing lip along its circumferencial direction
It is capitate along the section of rubber seal ontology radial direction, and its tup is positioned against on the inside of rubber seal ontology, hammers tail position into shape
It sets as annular groove side cell wall corresponding with reinforcing ring inner ring surface, hammer handle position is vertical with rubber seal ontology inner ring surface
It is connected, rubber seal body diameter is D and the internal diameter clearance fit with outer race, and gap value is 0.05 ~ 0.15, sealing lip
Lip diameter is d and is interference fitted with the outer diameter of bearing inner ring that magnitude of interference is 0.3 ~ 0.41, sealing the surface chamfer R, R of sealing lip
Value is 4 ~ 5.
Compared with prior art, the utility model has the beneficial effects that the utility model is mainly in needle bearing, energy
Lubricating grease is enough effectively reduced to overflow and while extraneous dust impurity enters, pass through reinforcing ring and improve holding for rubber seal ontology
Pressure energy power reduces influence of the vapour lock to seal clearance, slows down root and chews and prolongs the service life, structure of sealing lip advantages of simple,
Effective inside and outside two way seal is played to needle bearing, effect is more preferable.
Detailed description of the invention
Fig. 1 is the axonometric drawing of the rubber structure bearing seal check ring of the utility model；
Fig. 2 is the A direction view of Fig. 1；
Fig. 3 is the schematic diagram of the section structure of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, to the technical solution in the utility model carry out it is clear,
It being fully described by, it is clear that described embodiment is only a part of the embodiment of utility model, instead of all the embodiments,
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
Every other embodiment, fall within the protection scope of the utility model.
Specific embodiment 1: the utility model discloses a kind of rubber structure bearing sealing guards as shown in Fig. 1 ~ Fig. 3
Circle, including rubber seal ontology 1 and reinforcing ring 2,1 shape of rubber seal ontology are annular shape, rubber seal
1 end face outside of ontology is coaxially recessed with annular groove 1-1, and the insertion of reinforcing ring 2 is fixed in the annular groove 1-1, and rubber is close
1 outer ring surface of seal ontology and inner side end intersection location rounding off, 1 inner ring surface of rubber seal ontology are set along its circumferencial direction
There is sealing lip 1-2, the sealing lip 1-2 is capitate along the radial section of rubber seal ontology 1, and its tup is positioned against rubber
1 inside of glue sealing ring body, hammers tail position into shape as annular groove 1-1 side cell wall corresponding with 2 inner ring surface of reinforcing ring, hammer handle
Position is vertically connected with 1 inner ring surface of rubber seal ontology, and 1 outer diameter of rubber seal ontology is D and the internal diameter with outer race
Clearance fit, gap value are 0.05 ~ 0.15, and sealing lip 1-2 lip diameter is d and is interference fitted with the outer diameter of bearing inner ring, mistake
The amount of being full of is 0.3 ~ 0.41, and sealing surface chamfer R, the R value of sealing lip 1-2 is 4 ~ 5.
Specific embodiment 2: as shown in figure 3, present embodiment is made furtherly to specific embodiment one
