Abstract
The utility model relates to a bearing unit, and particularly relates to a bearing with a novel seal ring. The bearing mainly comprises a bearing inner ring, a bearing outer ring, and a novel structure seal ring. The bearing is characterized in that the novel structure seal ring is arranged at the position of a notch of the bearing. By adopting the bearing, the target of high air-tightness is achieved by utilizing a rubber coating on a skeleton by improving the seal ring; and the sealing effect is excellent.
Description
Technical field
The utility model relates to a kind of bearing unit, specifically, relates to a kind of novel seal circle bearing that has.
Background technique
Continuous development along with the automobile industry correlation technique, requirement to its performance that cuts down the consumption of energy and anti-muddy water is more and more higher, relative, wheel hub uses ball bearing unit and conical bearing unit as its important rotation base part, requires its band seal ring more and can enclose lubricating grease in advance to reach non-maintaining purpose.But vehicle Environmental Conditions difference (desert, rainforest, severe cold, heat etc.) is very big, and therefore the sealing to bearing also proposes higher requirement.Such bearing sealed ring is installed age of a draught animal position and is adopted grinding technique more at present, but grinding process takes time and effort, and manufacturing efficiency is not high.
The model utility content
In view of the defective that prior art exists, the purpose of this utility model is that a kind of novel seal circle bearing that has will be provided, and this bearing unit can satisfy field such as automobile fully to the usage requirement of high leak tightness.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of bearing with novel seal circle mainly comprises bearing inner race, bearing outer ring, new structure seal ring, it is characterized in that: described new structure seal ring is installed on bearing age of a draught animal position.
Described new structure seal ring is made up of inner frame, rubber body and dust cover, inner frame and dust cover are formed sealed cavity, place the caulking gum body in the sealing cavity, it is characterized in that: described caulking gum body comprises the body of rubber that matches with the inner frame shape, the main lip that extends out on the body of rubber, auxiliary lip and bilateral procheilon structure; Described auxiliary lip interference fit is on the inwall of dust cover; Described bilateral procheilon structure comprises the first limit lip and the second limit lip, and the first limit lip and the equal interference fit of the second limit lip are on the inwall of dust cover.
Further preferred, the described first limit lip and body of rubber are " L " shape of inclination, and its end interference fit is on the inwall of dust cover.
Further preferred, the described first limit lip and the second limit lip are " U " shape fork structure that tilts, and the angle of inclination of two limit lips is slightly different, the length of the first limit lip is longer than the length of the second limit lip, such structure has effectively guaranteed under the situation of the first limit lip seal performance failure, the second limit lip plays the effect of double seal protection, can prevent effectively also simultaneously that the first limit lip is because of wearing and tearing, under the situation of its sealability total failure, the second limit lip plays the effect of salable protection, further improves working life.
Further preferred, described main lip and auxiliary lip are arch structure, are convenient to the rubber elasticity return.
Further preferred, the matching relationship of described main lip and dust cover is divided into two kinds of situations, and a kind of situation is that main lip interference fit is on the inwall of dust cover; Another kind of situation is the inwall that main lip does not contact dust cover.The form of these two kinds of main lips is to decide according to the situation of the interior pressure of main lip and extraneous Environmental Conditions, adopts main lip interference fit in the structural type of dust cover inwall when pressing high, extraneous dust or muddy water serious in the main lip.
The beneficial effects of the utility model
The utility model is by improving seal ring, and utilizes outer encapsulate on the skeleton to reach the purpose of high leak tightness, its sealing effect excellence.
Description of drawings
Fig. 1 is for having novel seal circle bearing local location-age of a draught animal position view;
Fig. 2 is novel seal coil structures schematic representation one;
Fig. 3 is novel seal coil structures schematic representation two.
Among the figure: 1, inner frame, 2, dust cover, 3, the caulking gum body, 3a, body of rubber, 3b, main lip, 3c, auxiliary lip, 3d, the first limit lip, the 3e second limit lip, 4, bearing inner race, 5, bearing outer ring, 6, age of a draught animal position.
Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing:
A kind of bearing with novel seal circle mainly comprises bearing inner race 4, bearing outer ring 5, new structure seal ring as Fig. 1, it is characterized in that: described new structure seal ring is installed on bearing age of a draught animal position 6.
Described new structure seal ring, as Fig. 2, shown in Figure 3, formed by inner frame 1, caulking gum body 3 and dust cover 2, inner frame 1 is formed sealed cavity with dust cover 2, place caulking gum body 3 in the sealing cavity, it is characterized in that: described caulking gum body 3 comprises the body of rubber 3a that matches with the inner frame shape, the main lip 3b that extends out on the body of rubber 3a, auxiliary lip 3c and bilateral procheilon structure; Described auxiliary lip 3c interference fit is on the inwall of dust cover; Described bilateral procheilon structure comprises the first limit lip 3d and the second limit lip 3e, and the first limit lip 3d and the second limit equal interference fit of lip 3e are on the inwall of dust cover 2.
Further preferred, the described first limit lip 3d and body of rubber 3a are " L " shape of inclination, and its end interference fit is on the inwall of dust cover 2.
Further preferred, the described first limit lip 3d and the second limit lip 3e are " U " shape fork structure that tilts, and the angle of inclination of two limit lips is slightly different, the length of the first limit lip 3d is longer than the length of the second limit lip 3e, such structure has effectively guaranteed under the situation of the first limit lip 3d sealability inefficacy, the second limit lip 3e plays the effect of double seal protection, can prevent effectively also simultaneously that the first limit lip 3d is because of wearing and tearing, under the situation of its sealability total failure, the second limit lip 3e plays the effect of salable protection, further improves working life.
Further preferred, described main lip 3b and auxiliary lip 3c are arch structure, are convenient to the rubber elasticity return.
