Abstract
The invention relates to a vehicle bearing. The vehicle bearing comprises a bearing inner ring, wherein a bearing outer ring is arranged at the outer side of the bearing inner ring; multiple bearing rollers are arranged between the bearing inner ring and the bearing outer ring in the peripheral direction; a first sealing ring is arranged on one side between the bearing inner ring and the bearing outer ring, and a second sealing ring and a buckle are arranged on the other side; a sealing ring is arranged arranged on the outer side of the bearing outer ring; multiple ring inner cooling layers are arranged on the inner side wall of the bearing inner ring; multiple ring outer cooling layers are arranged on the outer side wall of the bearing outer ring; multiple inner cooling holes are formed in the peripheral direction of the bearing inner ring; and multiple outer cooling holes are formed in the outer side wall of the bearing outer ring. The bearing prevents the deformation caused by incapability of discharging heat for a long time in work; and meanwhile, the bearing is forcedly cooled through generating air currents in the inner cooling holes and the outer cooling holes in the high-speed rotating process, so that the cooling effect is improved, and the service life of the bearing is effectively prolonged.
Description
Technical field
This
inventionrelate to automobile technical field, particularly relate to
a kind of automobile bearing.
Background technique
I
country of statein newest standards " term and definition of automobile and trailer type " (GB/T3730.1-2001) to automobile just like giving a definition: by motivational drive, there is the vehicle of the non-track carrying of more than 4 or 4 wheels, be 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 thereof and (or) temporary items in its design and technical feature, and comprise operating seat, passenger car is no more than at most 9 seats.
Bearing is a kind of important spare part in contemporary machinery.Its major function is supported mechanical solid of rotation, reduces the friction factor in its movement process, and ensures its rotating accuracy.
By the difference of motor element frictional property, bearing can be divided into rolling bearing and the large class of sliding bearing two.Wherein rolling bearing standardization, seriation, but its radial dimension, vibration & noise is comparatively large 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 part, is made up of strictly speaking outer ring, inner ring, rolling element, retainer, sealing, the large part of lubricant oil six.Mainly possess outer ring, inner ring, rolling element and just surely can mean rolling bearing.By the shape of rolling element, rolling bearing is divided into ball bearing and the large class of roller bearing two.
The bearing of prior art can produce great heat after working long hours, and cannot effectively be got rid of, and makes bearing produce thermal stress deformation and damage or be out of shape, affects the normal work of bearing.
Summary of the invention
This
inventionobject be to overcome the deficiencies in the prior art, provide
a kind of automobile bearing.
This
inventionbe achieved through the following technical solutions:
a kind of automobile bearing, comprise bearing inner race, bearing outer ring is provided with outside described bearing inner race, described bearing inner race, several bearing rollers are circumferentially provided with between bearing outer ring, described bearing inner race, between bearing outer ring, side is provided with the first seal ring, opposite side is provided with the second seal ring and buckle, seal ring is provided with outside described bearing outer ring, described bearing inner race madial wall is provided with heat dissipating layer in several circles, described bearing outer ring outer side wall is provided with the outer heat dissipating layer of some circles, described bearing inner race is circumferentially provided with radiation hole in several, described bearing outer ring outer side wall is provided with several outer radiation holes.
As this
inventionoptimal technical scheme, described interior heat dissipating layer is embedded on bearing inner race madial wall, and thickness is 0.1mm ~ 0.5mm.
As this
inventionoptimal technical scheme, described outer heat dissipating layer is embedded on bearing outer ring outer side wall, and thickness is 0.1mm ~ 0.5mm.
As this
inventionoptimal technical scheme, described interior radiation hole, outer radiation hole shape are circular or oval.
Compared with prior art, originally
inventionbeneficial effect be: this
inventionby arranging outer heat dissipating layer, interior heat dissipating layer, interior radiation hole and outer radiation hole, during such use, the thermal stress in bearing can be discharged in time under the effect of heat dissipating layer, interior heat dissipating layer outside, bearing is avoided to produce distortion loose cannot the discharge of the heat that works long hours, simultaneously bearing in high-speed rotation in radiation hole and the inner air that produces of outer radiation hole flow forced heat radiation carried out to bearing, improve radiating effect, the effective life-span increasing bearing and use.
