Abstract
The utility model relates to technical field of bearings, especially a kind of bearing sealed ring, the skeleton to play a supportive role in rubber bodies and rubber bodies including circular ring shape, it is characterized by: the protrusion for being provided with circular ring shape on rubber bodies outer circumference surface is mutually interference fitted with the groove on bearing outer ring inner peripheral surface, rubber bodies inside edge is provided with the first sealing lip and the second sealing lip, first sealing lip, which is pressed on the outer end face of bearing inner race, prevents dust from entering, second sealing lip is withstood on the outer circumference surface of bearing inner race, and is tilted towards ball direction.The bearing sealed ring of the utility model seals outer circumference surface and the end face of bearing inner race using double envelope bead structures respectively, while playing the role of preventing dust from leaking into lubricating grease, and structure is simple, and easy for installation, practicability is good.
Description
Technical field
The utility model relates to technical field of bearings, especially a kind of bearing sealed ring.
Background technique
With the development of mechanical industry, the requirement to bearing is also higher and higher, more especially with sand-dust impurity etc.
Severe working condition seriously affects the service life of bearing if dust enters Bearing inner.
Seal bearing in operation, bearing temperature raising can make Bearing inner generate air motion, since pressure becomes larger, gas
Stream can be discharged to outside bearing, while lubricating grease can be discharged outside bearing and generate lubricating grease spillover, and lubricating grease is very few, Bearing Grinding
It damages speed to accelerate, in a few thing situation, it is extraneous that the lubricating grease of spilling is possible to pollution.
Utility model content
Purpose of the utility model is to solve bearing, dust enters the problem of leaking with lubricating grease during operation,
And provide a kind of bearing sealed ring.
The technical solution adopted in the utility model are as follows: a kind of bearing sealed ring, rubber bodies and rubber bodies including circular ring shape
The skeleton inside to play a supportive role, be provided on rubber bodies outer circumference surface the protrusion of circular ring shape with it is recessed on bearing outer ring inner peripheral surface
Slot is mutually interference fitted, and rubber bodies inside edge is provided with the first sealing lip and the second sealing lip, and the first sealing lip is pressed in bearing inner race
Outer end face on prevent dust from entering, the second sealing lip is withstood on the outer circumference surface of bearing inner race, and towards ball direction tilt.
Further, the protrusion is provided with elastic groove towards bearing outer end surface side.
Further, oil storage tank is provided between first sealing lip and the second sealing lip.
The utility model has the beneficial effects that the bearing sealed ring of the utility model seals axis using double envelope bead structures respectively
Outer circumference surface and the end face of inner ring are held, while playing the role of preventing dust from leaking into lubricating grease, structure is simple, installation side
Just, practicability is good.
Detailed description of the invention
Fig. 1 is the main view of the utility model.
In figure: 1- rubber bodies, 2- skeleton, 3- protrusion, the first sealing lip of 4-, the second sealing lip of 5-, 6- elastic groove, 7- oil storage
Slot.
Specific embodiment
The utility model is described further with reference to the accompanying drawing.
As shown in Figure 1, a kind of bearing sealed ring, the bone that plays a supportive role in rubber bodies 1 and rubber bodies 1 including circular ring shape
Frame 2 is provided with the protrusion 3 of circular ring shape on 1 outer circumference surface of rubber bodies and the groove on bearing outer ring inner peripheral surface is mutually interference fitted,
Protrusion 3 is provided with elastic groove 6 towards bearing outer end surface side, and 1 inside edge of rubber bodies is provided with the first sealing lip 4 and the second sealing lip,
First sealing lip 4, which is pressed on the outer end face of bearing inner race, prevents dust from entering, and the second sealing lip 5 withstands on the excircle of bearing inner race
It on face, and is tilted towards ball direction, is provided with oil storage tank 7 between the first sealing lip 4 and the second sealing lip 5.
Specific embodiment is the further explanation to the utility model rather than limits, and is come to those of ordinary skill in the art
It says and further transformation is done to structure in the case where not departing from the utility model in essence content, and all these transformation all should belong to
The protection scope of the appended claims for the utility model.
