Description
Technical field
The utility model belongs to auto parts field, and in particular to a kind of sealed vehicle transmission axle bearing.
Background technology
Heavy-duty car transmission shaft is the important leverage of automobile effectively operation and service life, and rolling bearing is truck drive shaft support
The critical component of assembly.It is often under the environment such as high temperature, low temperature, high humidity, dusty in transmission shaft work.Automobile is adding
In speed, deceleration rough ride, transmission shaft will produce the axial displacement of about 10-20mm with support, if the displacement directly passes through bearing
It acts in transmission shaft support, transmission shaft is easily caused to support earlier period damage.
Meanwhile sealed vehicle transmission axle bearing dust seal is the important guarantor of truck drive shaft effectively operation and service life
Barrier, the rolling bearing of transmission shaft is the critical component of vehicle driving shaft assembly, and transmission shaft is needed in the fabrication process by high temperature
Vulcanization, high temperature and pressure cleaning corrosion etc. processes, if occur in this process bearing water inlet phenomenon, corrosive liquid know from experience directly into
Enter Bearing inner, bearing working surface corrosion, bearing damage is caused transmission shaft to be caused to scrap.
Utility model content
The purpose of this utility model is to provide a kind of sealed vehicle transmission axle bearing with long service life.
Based on above-mentioned purpose, the utility model adopts the following technical solution：Sealed vehicle transmission axle bearing, including annular
Inner ring and outer ring, the width of inner ring is more than the width of outer ring, forms annular gap between outer ring and inner ring, in annular gap
It is furnished with steel ball, retainer is circumferentially with outside steel ball, annular gap both sides are equipped with sealing ring, dustproof cover, ring are equipped on the outside of sealing ring
The hollow space in shape gap is marked with lubricating grease.
Further, the dustproof cover includes main body, the first antelabium and the second antelabium.The body normal of dustproof cover is in inner ring
The main body of outer surface, dustproof cover is equipped with the first antelabium to annular gap internal protrusion close to one end of inner ring, and the first antelabium leans on
Nearly inner ring outer surface contact surface is equipped with the horizontal through hole of a diameter of 1 ~ 1.5mm, and the main body other end of dustproof cover is equipped with the second antelabium,
The main body junction of second antelabium and dustproof cover is obliquely installed, and the elongated end of the second antelabium is connected with bending section；Inner surface
Two edges position is equipped with fixed groove, is fastened in fixed groove at the top of bending section.
Further, the free end of the bending section of the dustproof cover is bent from outer ring to inner ring direction, bending section free end
Outer end face stretch out annular gap.
Further, the inner ring inner surface is equipped with annular lubricant slot.
Further, the width of outer ring is 2/3rds of inner race width.
The radial internal clearance minimum value of bearing provided by the utility model is 0.03mm, maximum value 0.035mm.
Compared with prior art, the utility model has the following advantages：
（1）The utility model increases sealing ring on the inside of traditional dustproof cover, enhances dust seal effect, reduces
The influence of corrosive liquids and dust to Bearing inner, extends the service life of bearing；
（2）The width of inner ring is more than the width of outer ring, in the case where ensureing that inner race width is constant, is passed not influencing bearing
It is appropriate to reduce outer ring width in the case of dynamic effect, the quality of bearing can be reduced, the burden of transmission shaft is reduced, increases transmission
The service life of axis；
（3）The horizontal through hole being arranged on the first antelabium of dustproof cover can provide cushioning effect, and reduction is caused by running car
Transmission shaft and influence of the bracing displacement to bearing, improve bearing service life；
（4）Inner ring inner surface is equipped with annular lubricant slot, it is possible to reduce the abrasion between transmission shaft and bearing extends bearing
Service life.
In conclusion the utility model is simple in structure, service life is long.
