Description
Technical field
The present invention relates to taper roll bearing, and in particular to a kind of wear-resisting double-row conical bearing.
Background technology
It is well known that bearing is a kind of conventional standard component, taper roll bearing therein due to can bear thrust axially and radially simultaneously and small volume and be widely used.But for a long time due to being limited by its structure and the accuracy of manufacture, it is generally used for middle low-speed heave-load industry, but recently as the continuous breakthrough of its correlation technique, its accuracy of manufacture and rotating speed are all enhanced, its less volume and excellent performance are just paid close attention to by vast auto manufacturing, therefore exploitation low noise, high speed taper roll bearing are the problems that bearing industry has been working hard capture for a long time.
The appearance of taper roll bearing, its advantage are directed to construction design of journal bearings in itself.This bearing is typically to be made up of four parts, i.e., cone, maintain a row roller, and outer ring by frame shape retainer on inner ring.The inner ring of same bearing and outer ring can be assembling, can also be separation.The latter is being assembled on axle or is being convenient in bearing block.For its bearing feature, taper roll bearing can bear the synthetic load of radial load, axial load, or both.On the other hand, for its volume, rolling element caused linear contact lay under load, assign the peak load bearing capacity of conical bearing, taper roll bearing can primely substitute the combination of different type bearing simultaneously, to bear the axially and radially load of various gears, thus in the case where bearing has same life, space shared by conical bearing, the volume than one group of combination bearing of cylindrical roller and ball are much smaller.Bearing also has the advantages that rigidity is big, performance is good simultaneously, so it is widely used in all machine drivings based on automobile.
At the same time, due to the special construction of taper roll bearing, although having above-mentioned many advantages and feature, also along with it is inevitable the shortcomings that.Plane contacts between inner ring, outer ring and taper roller, each other with slip, so bigger than the Friction Moment of Ball Bearings of same size is more；Secondly by the limitation of existing product design method, the friction that bearing is run more is caused to increase, lack of lubrication；Thus it is typically only capable to be applied to the use of middle low speed occasion, and it is fatal that this shortcoming is increasingly used for high speed situation to market and user.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide it is a kind of go slick, the wear-resisting double-row conical bearing that frictional resistance is low.The present invention technical thought be, taper roller is placed under closed environment, unimpeded lubrication channel is formed between taper roller and inner ring, outer ring, retainer, make taper roller in motion process, its surface is separated by one layer of complete hydrodynamic lubrication oil film, make neat liquid friction of the friction between taper roller and inner ring, outer ring, retainer for lubricating oil film interlayer, significantly decrease the friction of whole bearing, reduce heating, improve bearing accuracy.
The technical solution adopted by the present invention is as follows.
A kind of wear-resisting double-row conical bearing, including：
Overall outer ring, the outer ring have the coniform outer ring raceway face of the biserial formed in its inner peripheral surface；
Inner ring component, including a pair of inner ring elements, each inner ring element all have the coniform inner ring raceway face formed on its outer circumferential surface, and each inner ring element path side has path side flange, and each big footpath side of inner ring element has big footpath side flange；
Some taper rollers, the taper roller are circumferentially configured and freely rolled between inner ring roller surface and outer ring raceway face；
Keep frame member, including a pair of retainers, each retainer keeps taper roller using the multiple pocket holes formed between its multiple pillar and path side ring portion and big footpath side ring portion, wherein, annular array configures vertically for the path side ring portion and big footpath side ring portion, the multiple pillar links in the big footpath side ring portion and path side ring portion vertically, and circumferentially substantially equally spacedly sets；
The lateral surface of the outer end of two retainers is provided with outer seal sleeve；Radially outer surface is provided with annular recess at the middle part of outer ring, and annular recess is provided with fuel feed hole；Progressively arc-shaped transition between the inner ring raceway face of inner ring element and path side flange, big footpath side flange；Radially outer surface is provided with circular fin at the middle part of outer ring.
As optimal technical scheme, outer ring raceway face, inner ring raceway face, retainer are equipped with meshed grooves on the contact side with taper roller；The meshed grooves are made up of two groups of orthogonal grooves.
Beneficial effects of the present invention are as follows.
Inventor passes through substantial amounts of experimental study, it was found that the main reason for causing friction for a long time be due to taper roller with inner ring, outer ring contact area it is big caused by.The inner ring of taper roll bearing, contact of the outer ring with taper roller are changed to hydrodynamic lubrication liquid by face contact and contacted by the present invention, fundamentally improve bearing pivoting friction contact conditions, annular recess is provided with fuel feed hole simultaneously, be advantageous to that bearing friction power is greatly lowered, extend bearing life, improve rotating speed.Friction and caloric value when greatly reducing bearing working.Provided with circular fin, thickness of the bearing in main stress side is increased, improves device and stability.Be arranged on roller or inner ring, outer ring, the meshed grooves on retainer ensure that lubricating oil in taper roller rotation process, can be efficiently entering between the rolling surface of taper roller and inner ring, outer ring, retainer, improve lubricant effect.
