Abstract
The invention discloses a kind of dual-seal ball bearing, including inner ring, outer ring and it is placed in inner ring and the ball of outer ring, dust cap is respectively arranged with the both sides of the ball, both sides positioned at ball on the inside of the outer ring are respectively arranged with a neck, the inner surface of the neck both sides has a thickness difference, a plasticity cushion block is provided with the inside of the neck, the dust cap is arranged in the neck, and the inner side of dust cap and the contact outside of the plasticity cushion block.Compared with prior art, the present invention sets plasticity cushion block in neck, and dust cap is fixed on plasticity cushion block by jump ring, so as to which the rigid contact between original dust cap and bearing outer ring is become into flexible contact, improve the stability of dust cap, difficult for drop-off, dust cap forms multi-sealed between plasticity cushion block and jump ring.
Description
Technical field
The present invention relates to a kind of ball bearing, specifically a kind of dual-seal ball bearing with dust cap.
Background technology
Ball bearing structure is made up of inner ring, outer ring, the ball for being placed in inner ring and outer ring and dust cap.Dust cap passes through card
Spring is fixed on the both sides between bearing internal external circle.Bearing arrangement is close so as to influence easily by impulsive force in assembling or maintenance
Feng Xing.
The content of the invention
The technical problems to be solved by the invention are to be directed to above-mentioned the deficiencies in the prior art, and providing one kind prevents dust cap
Drop and ensure the doubling sealed bearing of Internal and external cycle sealing property.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of dual-seal ball bearing, including inner ring, outer ring and inner ring and the ball of outer ring are placed in, the two of the ball
Side is respectively arranged with dust cap, it is characterised in that：Both sides positioned at ball on the inside of the outer ring are respectively arranged with a neck, should
The inner surface of neck both sides has a thickness difference, and a plasticity cushion block, the dust cap are provided with the inside of the neck
It is arranged in the neck, and the inner side of dust cap and the contact outside of the plasticity cushion block.
A jump ring is additionally provided with the neck, the jump ring is located at the outside of the dust cap.
The inner surface that the lower surface of the plasticity cushion block is protruded from the inside of the neck；The lower surface of the jump ring is convex
For the lower surface of the plasticity cushion block.
The dust cap includes the first planar portions, the second planar portions, the 3rd planar portions and fourth plane portion, and described first is flat
Face is parallel with the 3rd planar portions, and second planar portions are inclined-plane and connection the first planar portions and the 3rd planar portions, and described the
Four planar portions and the 3rd planar portions vertical connection；First planar portions are between the jump ring and plasticity cushion block, institute
State the central area that the 3rd planar portions are located at the ball.
Compared with prior art, the present invention sets plasticity cushion block in neck, and dust cap is fixed on into modeling by jump ring
Property cushion block on, so as to which the rigid contact between original dust cap and bearing outer ring is become into flexible contact, improve dust cap
Stability, difficult for drop-off, dust cap forms multi-sealed between plasticity cushion block and jump ring.Meanwhile plasticity cushion block and
The lower end of jump ring such as protrudes from bearing inner race inner surface, there is provided more preferable position-limiting action, it is more difficult to come off.Dust cap it is upper
Clinoplain positioned at ball central area, the stress under the reset condition of dust cap is optimized, is unlikely to deform, improve dust-proof energy
Power.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Wherein：1st, inner ring；2nd, outer ring；3rd, steel ball；4th, dust cap；41st, the first planar portions；42nd, the second planar portions；43rd,
Three planar portions；44th, fourth plane portion；5th, jump ring；6th, plasticity cushion block；7th, neck.
Embodiment
Below in conjunction with the accompanying drawings, the present invention is elaborated：
As shown in figure 1, a kind of dual-seal ball bearing, including inner ring 1, outer ring 2 and the ball for being placed in inner ring 1 and outer 2 circle
3.A neck 7 is respectively arranged with positioned at the both sides of ball in the inner side of outer ring 2, the inner surface of the neck both sides has a thickness
Poor H, have in neck and be disposed with plasticity cushion block 6, dust cap 4 and jump ring 5 from inside to outside.
The lower surface of plasticity cushion block 6 protrudes from the inner surface of outer ring on the inside of neck；The lower surface of jump ring 5 protrudes from plasticity pad
The lower surface of block.
Dust cap 4 includes the first planar portions 41, the second planar portions 42, the 3rd planar portions 43 and fourth plane portion 44, and first
Planar portions 41 are parallel with the 3rd planar portions 43, and the second planar portions 42 are inclined-plane and connect the first planar portions 41 and the 3rd planar portions
43, fourth plane portion 44 and the vertical connection of the 3rd planar portions 43.First planar portions 41 are between jump ring 5 and plasticity cushion block 6, and
Three planar portions are located at the central area of ball 3.
In the present embodiment, plasticity cushion block 6 is polytetrafluoroethylplastic plastic.
The invention is not limited in described embodiment, those skilled in the art is i.e. public in the spirit for not departing from the present invention
In the range of opening, can still make some amendment or change, therefore the scope of the present invention using the scope that claims limit as
It is accurate.
