Abstract
The utility model relates to an automotive bearing, in particular to a single sealing lip combined-sealing double-row conical roller bearing with tension springs, which mainly solves the technical problems that in the prior art, a double-row conical roller bearing used by an automobile only adopts outer frameworks and sealing rings to prevent dust, the whole sealing device has poorer supporting force, the bearing oxidizes easily the iron sheets, and impurities, water, and the like are easy to intrude into the bearing from the outside, so that the service life of the bearing is reduced, the decomposing and cleaning cycle of the bearing is short, the use cost of a user is increased, the lubricating grease consumption is large, the operating environment cleanness is influenced, and the like. The utility model comprises inner rings and outer rings, wherein retainers are arranged between the inner rings and the outer rings and are provided with double-row conical rollers, two symmetrically arranged inner rings are provided, a cutting ferrule is arranged between the inner rings, inner frameworks with L-shaped cross sections and L-shaped dustproof covers are arranged between the end parts of the inner rings and the outer rings, sealing rings are arranged between the inner frameworks and the dust-proof covers, and the sealing rings wrap the tension springs.
Description
Technical field
The utility model relates to a kind of automobile bearing, especially relates to a kind of double-row conical bearing of combined labyrinth and carbon gland of the single sealing lip with extension spring.
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 just adopts outer skeleton and seal ring to prevent dust, the supporting force of whole sealing device is relatively poor, 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 of combined labyrinth and carbon gland of the single sealing lip with extension spring, it mainly is to solve the used double-row conical bearing of existing in prior technology automobile just to adopt outer skeleton and seal ring to prevent dust, the supporting force of whole sealing device is relatively poor, 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 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 the combined labyrinth and carbon gland of a kind of single sealing lip with extension spring 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, it is characterized in that described inner ring is symmetrically arranged two, be provided with cutting ferrule therebetween, be provided with section between the end of inner ring and outer ring and be inner frame of " L " type and the dust cover of " L " type, be provided with seal ring between inner frame and the dust cover, seal ring is enclosed with extension spring.After the dust cover of the inner frame of " L " type and " L " type is symmetrical arranged mutually, form the space of a rectangle like this, can be used for placing seal ring.Seal ring forms a hook type and hooks extension spring, under the effect of extension spring, can all the time seal ring be fixed on the dust cover like this, increases the contact force of seal ring and dust cover, prevent bearing in use grease spill, cause whole bearing failure.
As preferably, described seal ring is located on the dust cover, and seal ring is provided with a sealing lip, and sealing lip end and inner frame are fixed together.The body of seal ring is compressed on the dust cover, is close on the inner frame after its sealing lip extends upward, and the inner of inner frame curves inwardly.Single sealing lip is lived the clearance seal between dust cover and the inner frame, thereby can prevent effectively that dust from invading bearing inside.
Therefore, the seal ring place of the utility model between inner frame and dust cover is provided with extension spring, the seal ring of inside tightly can be compressed on the inner ring, prevent seal ring in use grease spill, can effectively prevent bearing failure, simple and reasonable for structure.

Accompanying drawing 2 is A portion structure for amplifying schematic representation of Fig. 1.
Component, position and numbering among the figure: inner ring 1, outer ring 2, retainer 3, double-row conical 4, cutting ferrule 5, inner frame 6, dust cover 7, seal ring 8, extension spring 9.
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 combined labyrinth and carbon gland of a kind of single sealing lip with extension spring of this example as Fig. 1, has inner ring 1 and outer ring 2, be provided with retainer 3 between inner ring and the outer ring, retainer is provided with double-row conical 4, and inner ring is symmetrically arranged two, is provided with cutting ferrule therebetween.As Fig. 2, be provided with section between the end of inner ring and outer ring and be inner frame 6 of " L " type and the dust cover 7 of " L " type, inner frame and dust cover are oppositely arranged, and be provided with the seal ring 8 of hook type between inner frame and the dust cover, seal ring is enclosed with extension spring 9, the body of seal ring is located on the dust cover 7, and seal ring is provided with a sealing lip, and sealing lip end and inner frame 6 are fixed together.
During use, assemble inner ring 1, outer ring 2, double-row conical 4 after, inner frame 6, dust cover 7, seal ring 8 be pressed onto between inner ring 1 and 2 ends, outer ring get final product.At last whole double-row conical bearing is packed into and can use in the automobile.
The above only is a specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and variation of being done or modification all are encompassed among the claim of the present utility model.
