Abstract
The invention discloses one kind without retainer high speed roller bearing, including outer ring, inner ring, carrying rolling element and separation rolling element composition；It is characterized in that：Inner ring, outer ring are installed with one heart, and carrying rolling element routinely requires to be arranged on the raceway circumference that outer ring and inner ring are constituted, and carrying rolling element adds separation rolling element between any two, and the diameter for separating rolling element is slightly less than carrying rolling element.It is an advantage of the invention that：Traditional retainer is replaced using rolling element is separated, avoid the frictional heating and wear-out failure problem in conventional high rate bearing between retainer and rolling element, simultaneously because the cladding without retainer, the radiating condition of carrying rolling element will also be greatly improved, so as to improve the high speed performance of bearing；Retainer is eliminated, the life-span of bearing and Jing Yin performance can be effectively improved.
Description
Technical field
The present invention relates to high speed roller bearing field, more particularly to one kind is without retainer high speed roller bearing, Neng Gougeng
The good use requirement for meeting the high-speed bearings such as aero-engine, high ferro.
Background technology
With hair of the high speed machine high speed bearing such as aero-engine to frictional heating and wear problem increasingly sensitivity
Exhibition requires, more and more sharp the problems such as friction heat dissipation problem between traditional retainer and rolling element, wear-out failure.Traditional solution
Certainly method is to improve constantly the requirement to retainer, it is desirable to which the material of retainer also requires thermal conductivity in addition to some strength
Well, friction factor is small, wearability is good, impact flexibility is strong, density is smaller and linear expansion coefficient and rolling element are close, machining accuracy is high
Etc. rigors, cause current technology means to become the limit, room for improvement is limited.
One kind proposed by the present invention can preferably avoid above mentioned problem, compared to tradition without retainer high speed roller bearing
Rolling bearing, replace traditional retainer using rolling element is separated, it is to avoid retainer and rolling element in conventional high rate bearing
Between frictional heating and wear-out failure problem, simultaneously because the cladding without retainer, carry the radiating condition of rolling element
It will be greatly improved, and so as to improve the high speed performance of bearing, can also effectively improve the life-span of bearing and Jing Yin performance.Compared to patent
（The patent No.：201410621736.6）The advantage of the full type rolling bearing of proposition is：Structure is simpler reliable, Neng Goushi
For high speed situation.
The content of the invention
The present invention solves the technical problem of for present in current high-speed bearing between rolling element and retainer
The bearing lubrication effect that frictional heating, excessive wear are caused, which deteriorates, causes bearing running hot, excessive wear to cause what retainer was destroyed
Problem.
In order to solve the above technical problems, a kind of technical scheme that the present invention is used is：One kind is without retainer high speed scroll axle
Hold, including outer ring, inner ring, carrying rolling element and separation rolling element composition；It is characterized in that：Inner ring, outer ring are installed with one heart, carrying
Rolling element routinely requires to be arranged on the raceway circumference that outer ring and inner ring are constituted, and carrying rolling element adds separation rolling between any two
Kinetoplast, the diameter for separating rolling element is slightly less than carrying rolling element.
Carrying rolling element described further can be existing various rolling element, comprising：Circular ball, cylindrical roller, rolling
Pin etc., carrying rolling element is evenly distributed on the raceway between inner ring and outer ring by means of separating the buffer action of rolling element.
Further, the separation rolling element construction profile is moistened with rolling element is carried with the solid such as graphitiferous or immersion oil ceramics
The lightweight of lubrication prescription, soft material make, and its diameter is slightly less than the diameter of carrying rolling element, it is spaced be evenly distributed on inner ring and
On raceway between outer ring.
The beneficial effects of the invention are as follows：First, traditional retainer is replaced using separating rolling element, it is to avoid conventional high rate axle
The frictional heating and wear-out failure problem between retainer and rolling element are held, simultaneously because the cladding without retainer, carrying
The radiating condition of rolling element will also be greatly improved, so as to improve the high speed performance of bearing；2nd, separate and roll relative complex holding
For frame, manufacturing process can be simplified, manufacturing cost is reduced；3rd, broken down in particular cases in lubricating system, separate rolling
The self lubricity of kinetoplast is also beneficial to maintain the of short duration work of bearing；4th, retainer is eliminated, the life-span of bearing can be effectively improved
With Jing Yin performance.

Fig. 3 is the dimensional structure diagram of a preferred embodiment of the present invention.
It is attached：The mark of each part is as follows in figure：1st, outer ring；2nd, inner ring；3rd, rolling element is carried；4th, rolling element is separated.
Embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention are more
It is easy to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
Fig. 1-3 are referred to, the embodiment of the present invention includes：One kind is without retainer high speed roller bearing, including outer ring（1）, it is interior
Circle（2）, carrying rolling element（3）With separation rolling element（4）Composition；It is characterized in that：Inner ring（2）, outer ring（1）Install, hold with one heart
Carry rolling element（3）Routinely require to be arranged in outer ring（1）And inner ring（2）On the raceway circumference of composition, rolling element is carried（3）Two-by-two
Between add separate rolling element（4）, separate rolling element（4）Diameter be slightly less than carrying rolling element（3）.Carry rolling element（3）With
Separate rolling element（4）It is alternately arranged, separates rolling element（4）The retainer of substitution traditional bearing plays the scattered carrying rolling element of separation
Effect, the gentle touchdown friction that rolling element is subjected only to itself centrifugal force and adjacent carrying rolling element is separated during bearing working
Power, is not subject to other service loads, only plays a part of separating and lubricating bearing rolling element.
Carrying rolling element of the present invention（3）It can be existing various rolling element, carry rolling element（3）By means of separating
Rolling element（4）Buffer action be evenly distributed on inner ring（2）And outer ring（1）Between raceway on, play normal bearing roller
Support bearing effect.
Separation rolling element of the present invention（4）Construction profile is solid with graphitiferous or immersion oil ceramics etc. with rolling element is carried
The lightweight of body lubricant, soft material make, and its diameter is slightly less than carrying rolling element（3）Diameter, it is spaced to be uniformly distributed
In inner ring（1）And outer ring（2）Between raceway on, separate rolling element the effect for functioning as traditional retainer, make rolling
Body is uniformly distributed, while having lubrication concurrently.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
Equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or other related technology necks are used in indirectly
Domain, is similarly included in scope of patent protection of the present invention.
