Abstract
The present invention relates to a kind of deep groove ball bearing seal assembly, the sealing lips of the seal assembly is L-shaped, sealing lips one end be clipped on steel skeleton, seal the other end of lips and with offer oil groove on the contact surface of inner ring；It seals lips and steel skeleton constitutes sealing ring；The outer diameter and outer ring Interference contact of sealing ring, the internal diameter and inner ring Interference contact of sealing ring；Retainer, steel ball are located between outer ring and inner ring.Using the present invention, extraneous particle and dirt are not easy directly to contact with sealing lips, extend the service life of sealing ring；Sealing lips inner ring inner surface is radially ridden over by steel skeleton to be sealed, sealed reliable, the gas discharge that the oil groove opened up expands when can be by bearing operation, prevent lubricating grease excessive, further improve sealing performance, and positioned by the Interference contact of steel skeleton and inner surface, positioning is convenient, and processing technology is simple.
Description
Technical field
The present invention relates to technical field of bearings, especially a kind of deep groove ball bearing seal assembly.
Background technique
Deep groove ball bearing structure is simple, is a most widely used class bearing.With the development of machinery industry, to deep-groove ball
The sealing requirements of bearing are higher and higher.Deep groove ball bearing need to install seal assembly in bearing both ends of the surface when using, and be in order to anti-
Only lubricating grease will not be lost in use and extraneous dust or other dirts enter Bearing inner.Currently, China exists
Design bearing aspect is sealed there are still many problems, traditional single lip seal structure is still used by many bearing producers, due to
The accuracy of manufacture is not high, causes sealing effect bad, and sealing wear is big, and leakage rouge phenomenon is serious, but single lip seal structure, manufacturing cost
It is low, therefore, single lip seal structure is improved, can improve bearing service life and enhance sealing effect is one meaningful
Project.
Summary of the invention
It is an object of the present invention to provide traditional single lip seal sealing structure effect can be overcome poor, sealing wear is big, in bearing
A kind of deep groove ball bearing seal assembly of the serious problem of portion's grease leakage.
The technical solution adopted by the present invention is that: a kind of deep groove ball bearing seal assembly, it is characterised in that it includes outer ring, steel
Skeleton, sealing lips, retainer, inner ring and steel ball, sealing lips is L-shaped, and sealing lips one end is clipped on steel skeleton, sealing lip
The other end of piece and with offer oil groove on the contact surface of inner ring；It seals lips and steel skeleton constitutes sealing ring；Outside sealing ring
Diameter and outer ring Interference contact, the internal diameter and inner ring Interference contact of sealing ring；Retainer, steel ball are located between outer ring and inner ring.
Using the present invention, extraneous particle and dirt are not easy directly to contact with sealing lips, extend the use of sealing ring
Service life；Sealing lips is radially ridden over inner ring inner surface by steel skeleton to be sealed, sealed reliable, the oil groove opened up can incite somebody to action
The gas discharge expanded when bearing operation, prevents lubricating grease excessive, further improves sealing performance, and by steel skeleton and outside
The Interference contact of circle inner surface is positioned, and positioning is convenient, and processing technology is simple.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is that contact schematic diagram of the lips with inner ring is sealed in the present invention.
In figure: outer ring 1, steel skeleton 2, sealing lips 3, retainer 4, inner ring 5, steel ball 6 and oil groove 7.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
Referring to Fig.1, Fig. 2, the deep groove ball bearing seal assembly include outer ring 1, steel skeleton 2, sealing lips 3, retainer 4,
Inner ring 5 and steel ball 6, sealing lips 3 it is L-shaped, sealing 3 one end of lips be clipped on steel skeleton 2, seal lips 3 the other end and with
Oil groove 7 is offered on the contact surface of inner ring 5；It seals lips 3 and steel skeleton 2 constitutes sealing ring；The outer diameter and 1 mistake of outer ring of sealing ring
It is full of contact, the internal diameter and 5 Interference contact of inner ring of sealing ring；Retainer 4, steel ball 6 are located between outer ring 1 and inner ring 5.
Among the above, since sealing lips 3 is clipped on 2 centre of steel skeleton, extraneous particle and dirt is not easy and sealing lip
Piece 3 directly contacts, and extends the service life of sealing ring；Determined by the Interference contact of steel skeleton 2 and 1 inner surface of outer ring
Position, positioning is convenient, keeps the seal groove processing technology of outer ring 1 simple；It is sealed using radial pressing, by steel skeleton 2 by sealing lip
Piece 3 rides over 5 inner surface of inner ring and is sealed, sealed reliable；In the state of operating, the temperature in bearing is consistently higher than bearing
Ambient temperature, the raising of temperature is so that gas expansion, makes lubricating grease have excessive possibility in bearing.But due to sealing lips
Oil groove 7 is offered on 3, the gas discharge expanded when can be by bearing operation prevents lubricating grease excessive, and play the work of oil storage lubrication
With further improving sealing performance.
