Abstract

The invention relates to a support bearing for a shafting hanger of an automobile. The support bearing comprises an inner bearing ring; an outer bearing ring is arranged at the outer side of the inner bearing ring; a plurality of bearing rollers are arranged between the inner bearing ring and the outer bearing ring along a circumferential direction; two sides located between the inner bearing ring and the outer bearing ring are provided with a first sealing ring and a second sealing ring; the first sealing ring comprises a reinforcing layer, a first fixture block and a second fixture block; the reinforcing layer is arranged in the first sealing ring; and the second sealing ring is of an H-shaped structure. In use of the support bearing, sealing performance can be improved under the action of the first sealing ring and the second sealing ring, and external silt, dust and the like can be prevented from entering the bearing, so the service life of the bearing can be effectively prolonged.

Description

A kind of truck drive shaft hanger supports bearing

Technical field

The present invention relates to automobile technical field, relate in particular to a kind of truck drive shaft hanger supports bearing.

Background technology

In China country newest standards " term and definition of automobile and trailer type " (GB/T3730.1-2001) to automobile just like giving a definition: by power drive, the vehicle with the non-track carrying of more than 4 or 4 wheel, is mainly used in: carrying personnel and (or) goods; The vehicle of traction carrying personnel and (or) goods; Specific use. Passenger car is mainly used in carrying passenger and personal luggage and (or) interim article in its design and technical characteristic, and including operating seat, passenger car is no more than at most 9 seats.

Bearing is a kind of important spare part in contemporary plant equipment. Its major function is supported mechanical rotary body, reduces the coefficient of friction in its motion process, and ensures its rotating accuracy.

Press the difference of motor element frictional property, bearing can be divided into rolling bearing and the large class of sliding bearing two. Wherein standardization of rolling bearing, seriation, but its radial dimension, vibration and noise are larger compared with sliding bearing, and price is also higher.

Rolling bearing is generally made up of outer ring, inner ring, rolling element and retainer four parts, is made up of strictly speaking outer ring, inner ring, rolling element, retainer, sealing, the large part of lubricating oil six. Mainly possess outer ring, inner ring, rolling element and just can surely mean rolling bearing. Press the shape of rolling element, rolling bearing is divided into ball bearing and the large class of roller bearing two.

The automobile bearing of prior art is under poor environment, and the impurity such as silt, dust easily affect coordinating of sealing lip on sealing ring and inner ring and outer ring, cause the inner roller of bearing easily to wear and tear, and cause the service life of bearing short.

Summary of the invention

The object of the invention is in order to overcome the deficiencies in the prior art, a kind of truck drive shaft hanger supports bearing is provided.

The present invention is achieved through the following technical solutions:

A kind of truck drive shaft hanger supports bearing, comprise bearing inner race, described bearing inner race outside is provided with bearing outer ring, between described bearing inner race, bearing outer ring, circumferencial direction is provided with several bearing rollers, between described bearing inner race, bearing outer ring, on both sides, be provided with the first sealing ring, the second sealing ring, described the first sealing ring comprises enhancement Layer, the first fixture block and the second fixture block, and described enhancement Layer is arranged on the first sealing ring inside, and described the second sealing ring is H type structure.

As the preferred technical solution of the present invention, described enhancement Layer is that wire quality is made.

As the preferred technical solution of the present invention, one-body molded between described the first fixture block and the second fixture block and the first sealing ring.

As the preferred technical solution of the present invention, between described the second sealing ring and bearing inner race, bearing outer ring for being fastenedly connected.

Compared with prior art, the invention has the beneficial effects as follows: the present invention is by arranging the first sealing ring, the second sealing ring, while use like this, under the effect of the first sealing ring, the second sealing ring, can improve sealing, avoid extraneous silt, dust etc. to enter bearing inside simultaneously, effectively increased the life-span that bearing uses.

Brief description of the drawings

Fig. 2 is A portion structure for amplifying schematic diagram in Fig. 1.

Detailed description of the invention

In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated. Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.

Refer to Fig. 1 and Fig. 2, Fig. 1 is structural representation of the present invention, and Fig. 2 is A portion structure for amplifying schematic diagram in Fig. 1.

A kind of truck drive shaft hanger supports bearing, comprise bearing inner race 1, described bearing inner race 1 outside is provided with bearing outer ring 2, described bearing inner race 1, between bearing outer ring 2, circumferencial direction is provided with several bearing rollers 3, described bearing inner race 1, between bearing outer ring 2, on both sides, be provided with the first sealing ring 4, the second sealing ring 5, described the first sealing ring 4 comprises enhancement Layer 401, the first fixture block 402 and the second fixture block 403, wherein said enhancement Layer 401 is made for wire quality, and one-body molded between described the first fixture block 402 and the second fixture block 403 and the first sealing ring 4, can improve like this sealing of the first sealing ring 4.

Described enhancement Layer 401 is arranged on the first sealing ring 4 inside, and described the second sealing ring 5 is H type structure, between wherein said the second sealing ring 5 and bearing inner race 1, bearing outer ring 2 for being fastenedly connected. While use like this, under the effect of the first sealing ring 4, the second sealing ring 5, can improve sealing, avoid extraneous silt, dust etc. to enter bearing inside simultaneously, effectively increase the life-span that bearing uses.

In description of the invention, it will be appreciated that, term " orientation or the position relationship of the instruction such as " center ", " top ", " end ", " interior ", " outward " they are based on orientation shown in the drawings or position relationship; be only the present invention for convenience of description and simplified characterization; instead of indicate or imply that the device of indication or element must have specific orientation, construct and operation with specific orientation, therefore can not be interpreted as limitation of the present invention.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
