Abstract
The utility model discloses a kind of novel bearing sealing rings, it is related to sealing ring technical field.It includes outer skeleton, inner frame, rubber and Magnetic adhesive, the surface of outer skeleton is bonded with rubber, the surface of inner frame is bonded with Magnetic adhesive, the exocoel of maze-type structure is formed between outer skeleton and inner frame, first bending part of the exocoel, which is provided with, does not contact lip, this, which does not contact lip, can not only block the foreign matters such as muddy water, while will not generate torque；Second bending part of inner cavity is provided with reversed lip, and reversed lip can block external muddy water, can also prevent internal grease from leaking out.The utility model is using double-lip and does not contact labyrinth structure, torque is effectively reduced, while not increasing product occupied space, does not change original mounting means, does not increase product cost, improves performance, use easy to spread.
Description
Technical field
The utility model relates to sealing ring technical fields, and in particular to a kind of novel bearing sealing ring.
Background technique
Currently, bearing is to guarantee sealing when in use, use three lip contact type sealing structures, torque is big, is unable to satisfy more
The light-weighted demand in market rotates difficultly, and space is limited, is not only not easy to client and installs and uses, and is at high cost, passes simultaneously
The bearing arrangement of system does not monitor the function of vehicle wheel rotational speed, influences properties of product, and properties of product are more single.Bearing industry not
Under the disconnected background for reducing bearing torque, to guarantee sealing performance, under the premise of seal lip contact force need to be kept, it can be promoted
Space very little.To solve the above-mentioned problems, it is particularly necessary to design a kind of novel bearing sealed ring.
Summary of the invention
In view of the shortcomings of the prior art, the utility model aims to provide a kind of novel bearing sealing ring,
Structure is simple, and design rationally, using double-lip and does not contact labyrinth structure, torque is effectively reduced, occupies little space simultaneously, is convenient for
Client installs and uses, and improves performance, practical, use easy to spread.
To achieve the goals above, the utility model is achieved through the following technical solutions: a kind of novel bearing is close
Seal, including outer skeleton, inner frame, rubber and Magnetic adhesive, the surface of outer skeleton are bonded with rubber, and the surface of inner frame is bonded with
Magnetic adhesive is formed with the exocoel of maze-type structure between outer skeleton and inner frame, the first bending part of the exocoel, which is provided with, not to be connect
Lip is touched, this, which does not contact lip, can not only block the foreign matters such as muddy water, while will not generate torque；Second bending part of inner cavity is set
It is equipped with reversed lip, reversed lip can block external muddy water, can also prevent internal grease from leaking out.
Preferably, the rubber is bonded as one after adding sulphur with outer skeleton, the Magnetic adhesive add after sulphur with in-seam
Frame is bonded as one.
Preferably, the Magnetic adhesive is compound using strontium ferrite magnetic powder or barium ferrite magnetic powder and butyronitrile synthetic rubber
Made of Magnetic adhesive, good combination property is moderate, and retentivity and thermal stability are high.
The utility model has the beneficial effects that the present apparatus does not contact labyrinth structure by reducing contact lip quantity, increase, drop
Low torque；By the magnetic circle number of magnetic poles of detection, vehicle wheel rotational speed can be monitored；This is compact-sized, is not influencing what client installed and used
Meanwhile greatly improve properties of product, while not increasing product occupied space, do not change original mounting means, do not increase product at
This, has a extensive future.
Detailed description of the invention
It is described in detail the utility model with reference to the accompanying drawings and detailed description；
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
Referring to Fig.1, present embodiment uses following technical scheme: a kind of novel bearing sealing ring, including outer skeleton
1, inner frame 2, rubber 3 and Magnetic adhesive 4, the surface of outer skeleton 1 are bonded with rubber 3, and the surface of inner frame 2 is bonded with Magnetic adhesive 4,
The exocoel 5 of maze-type structure is formed between outer skeleton 1 and inner frame 2, the first bending part of the exocoel 5, which is provided with, does not contact lip
Mouth 6, the second bending part of inner cavity 8 is provided with reversed lip 7.
It is worth noting that, being bonded as one after the rubber 3 plus sulphur with outer skeleton 1, after the Magnetic adhesive 4 plus sulphur
It is bonded as one with inner frame 2；Vulcanize rubber and Magnetic adhesive, increase intensity and mechanical performance, there is physically better characteristic.
In addition, the Magnetic adhesive 4 it is compound using strontium ferrite magnetic powder or barium ferrite magnetic powder and butyronitrile synthetic rubber and
At Magnetic adhesive, compared to the vectolite magnetic powder generallyd use on the market, comprehensive performance is more preferable, moderate, retentivity
And thermal stability is high.
For present embodiment in use, be fitted in the end face of bearing, which can stop the muddy water, different in outside
Object enters, while can also seal Bearing inner grease leakage.Specifically, its working principle is that: added in this ring structure
Labyrinth structure is not contacted, is provided in labyrinth and does not contact 7 two lip 6, reversed lip lip configurations, compared to three traditional lips
Contact type sealing structure reduces by a lip, substantially reduces torque；Wherein, maze-type structure makes the external muddy water to splash, different
Object need to turn it is several it is curved can just touch lip, from source reduce foreign matter entrance, without contact lip 6 then by inside and outside skeleton
Between the muddy water foreign matter that sprays into of gap block, and torque will not be generated, reversed lip 7 substitutes traditional pair by a lip
Lip can block external muddy water and seal internal grease, guarantee air-tightness.
Present embodiment uses Magnetic adhesive, which is used for the hub bearing of vehicle, passes through the magnetic circle magnetic pole of detection
Number can monitor the revolving speed of wheel, and provide the wear surface of seal lip, effectively expansion performance；This ring structure is compact, accounts for
Small with space, it is convenient to install and use, while greatly improving performance, while not changing original mounting means, does not increase product cost,
Have a vast market application prospect.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
