Abstract
The utility model 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 utility model 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
It the utility model is related 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 in assembling or maintenance, easily by impulsive force, so as to influence
Sealing.
The content of the invention
Technical problem to be solved in the utility model is to be directed to above-mentioned the deficiencies in the prior art, and providing one kind prevents
Dirt lid, which drops, ensures the doubling sealed bearing of Internal and external cycle sealing property.
In order to solve the above technical problems, the technical solution adopted in the utility model 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, in the ball
Both sides be 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 card
Groove, the inner surface of the neck both sides have a thickness difference, and a plasticity cushion block is provided with the inside of the neck, described anti-
Dirt lid 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 utility model sets plasticity cushion block in neck, and is fixed dust cap by jump ring
On plasticity cushion block, so as to which the rigid contact between original dust cap and bearing outer ring is become into flexible contact, improve anti-
The stability of dirt lid, difficult for drop-off, dust cap forms multi-sealed between plasticity cushion block and jump ring.Meanwhile plasticity pad
The lower end of block and 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
The upper clinoplain positioned at ball central area, optimize the stress under the reset condition of dust cap, be unlikely to deform, improve anti-
Dirt ability.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
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 utility model is elaborated：
As shown in figure 1, a kind of dual-seal ball bearing, including inner ring 1, outer ring 2 and it is placed in inner ring 1 and outer 2 circle
Ball 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 one
Thickness difference 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 utility model is not limited to described embodiment, those skilled in the art do not depart from it is of the present utility model
In the i.e. open scope of spirit, it can still make some amendments or change, therefore rights protection scope of the present utility model is with claims
The scope of restriction is defined.
