Abstract
The utility model 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 utility model, 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 utility model 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
The utility model aim, which is to provide, can overcome traditional single lip seal sealing structure effect poor, and sealing wear is big, axis
Hold a kind of deep groove ball bearing seal assembly that internal grease leaks serious problem.
The technical solution adopted in the utility model is: a kind of deep groove ball bearing seal assembly, it is characterised in that it includes outer
Circle, 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,
Seal lips the other end and with offer oil groove on the contact surface of inner ring；It seals lips and steel skeleton constitutes sealing ring；Sealing
The outer diameter and outer ring Interference contact of circle, the internal diameter and inner ring Interference contact of sealing ring；Retainer, steel ball be located at outer ring and inner ring it
Between.
Using the utility model, extraneous particle and dirt are not easy directly to contact with sealing lips, extend 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
The gas discharge expanded when can be by bearing operation, prevents lubricating grease excessive, further improves sealing performance, and pass through steel skeleton
It is positioned with the Interference contact of inner surface, positioning is convenient, and processing technology is simple.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is that contact schematic diagram of the lips with inner ring is sealed in the utility model.
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 utility model is described in further detail with reference to the accompanying drawing.
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.
