Abstract
The utility model relates to a bearing for an automobile, in particular to a double-line conical roller bearing with a combined seal ring, which mainly solves the technical problems that in the prior art, the double-line conical roller bearing used by the automobile adopts a dust cover to prevent dust, so that the sediment, impurities, water and the like can invade into the bearing from outer part, the oil in the interior of the bearing can leak without an effective seal ring, so the service life of the bearing is reduced, the decomposition cleaning cycle of the bearing is shortened, and the use cost of a user is increased. The utility model comprises an inner and an outer ring, wherein a retainer is arranged between the inner ring and the outer ring, the retainer is provided with double-line conical rollers, an inner dust cover and an outer dust cover are arranged between the inner ring and the outer ring, a sealing element is arranged between an inner framework and the outer dust cover, the sealing element comprises a sealing element body attached on the inner skeleton, the sealing element body is extended to be provided with a first lip and a second lip, wherein the first lip is contacted with the outer end of the outer dust cover, and the second lip is contacted with the inner end of the outer dust cover.
Description
Technical field
The utility model relates to a kind of automobile bearing, especially relates to a kind of double-row conical bearing with combined seal ring.
Background technique
Automobile has generally comprised inner ring, outer ring with bearing, is fixed with single-row by retainer or the biserial roller between the Internal and external cycle.Chinese patent discloses a kind of sealing double-row conical bearing (notice of authorization number: CN 2625638Y) of new structure, it comprises an outer ring with double raceway, two single raceway inner rings, two retainers, a cone spacer between two row rollers and inner ring, the external diameter of outer ring are " V " font, each adaptively has a skeleton in the exterior edge face of two retainers, the all suitable seal ring that is combined with on each skeleton, the sectional shape of skeleton, seal ring is like channel-section steel, and the material of seal ring is a rubber.Chinese patent also discloses a kind of double-row conical bearing (notice of authorization number: CN 2864213Y) of two sides band dust-proof cover, it is made up of outer ring, inner ring, tapered roller, retainer and spacer ring, the bearing outer ring both ends of the surface have dust-proof cover, and the outer ring is directly as the working surface that supports.But the used double-row conical bearing of this automobile is to adopt dust cover to prevent dust, bearing makes iron scale, slag inclusion, water etc. invade from the outside easily, thereby reduced bearing working life, it is short that bearing decomposes the Cleaning period, improved customer using cost, and the lubricating grease consumption is big, influences the operating environment cleaning.
The model utility content
The utility model provides a kind of double-row conical bearing with combined seal ring, it mainly is that the used double-row conical bearing of solution existing in prior technology automobile is to adopt dust cover to prevent dust, silt, slag inclusion, water etc. are invaded from the outside, the bearing internal grease is not because of there being effective sealing spill and leakage, thereby reduced bearing working life, it is short that bearing decomposes the Cleaning period, improved customer using cost, and the lubricating grease consumption is big, influences the technical problem of operating environment cleaning etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The double-row conical bearing of band combined seal ring of the present utility model, comprise inner ring and outer ring, be provided with retainer between inner ring and the outer ring, retainer is provided with double-row conical, be provided with inner frame of " L " type and the outer dust cover of " L " type between the end of described inner ring and outer ring, be provided with Sealing between inner frame and the outer dust cover, Sealing comprises attached to the seal body on the interior dust cover, extend first lip on the seal body, second lip, wherein the outer end of the outer dust cover of first lip contact is located, the place, the inner of the outer dust cover of second lip contact.Inner ring has cell body at the place, interior outer end of double-row conical, can take lubricating grease in, avoids double-row conical wearing and tearing inner ring when rolling.Extended first lip of seal body, second lip are blocked in the place, interior outer end of outer dust cover respectively, therefore by the dustproof lip of twice, can prevent effectively that dust from entering bearing inside.The outer dust cover of the interior dust cover of " L " type and " L " type is symmetrical arranged mutually, forms the space of a rectangle like this, can be used for placing Sealing.
As preferably, extend the 3rd lip on the described seal body, the 3rd lip is located between first lip, second lip, the middle part of the outer dust cover of the 3rd lip contact.The 3rd lip can place further that to prevent that dust from entering into bearing inner and effectively prevent bearing internal grease spill and leakage and the bearing that causes is stuck.
As preferably, described inner ring is split type, is convenient to assembling.
As preferably, the angle α of the bus of described double-row conical outer surface and bearing medial axis is 15-18 ゜, and the angle optimum alpha can be 17 ゜, can guarantee that like this double-row conical can roll swimmingly, reduces friction.
Therefore, the utlity model has bearing can change should be steadily, flexibly, the characteristics of fluent phenomenon, and be provided with combined type dust sealing mechanism at the two ends of bearing, can prevent that silt, slag inclusion, water etc. from invading bearing inside from the outside, simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is structure for amplifying schematic representation of the utility model Sealing.
Component, position and numbering among the figure: inner ring 1, outer ring 2, retainer 3, double-row conical 4, inner frame 5, outer dust cover 6, seal body 7, first lip 8, second lip 9, the 3rd lip 10.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the double-row conical bearing of the band combined seal ring of this example, use on hippocampus M1, five water chestnut N5 automobiles.As Fig. 1, an outer ring 2 and split type inner ring 1 are arranged, be provided with retainer 3 between inner ring and the outer ring, retainer is provided with double-row conical 4, and the angle α of the bus of double-row conical outer surface and bearing medial axis is 17 ゜.Be provided with end face between the end of inner ring and outer ring and be symmetrical arranged mutually with end face 6, two dust covers of outer dust cover, make it form the cavity of a rectangle, be provided with Sealing in the cavity for " L " type for the inner frame 5 of " L " type.As Fig. 2, Sealing comprises attached to the seal body on the inner frame 7, extends first lip 8, second lip 9 on the seal body, and wherein the outer end of the outer dust cover of first lip contact is located, the place, the inner of the outer dust cover of second lip contact.Also extend the 3rd lip 10, the three lips on the seal body and be located between first lip, second lip, the middle part of the outer dust cover of the 3rd lip contact.
