Abstract
The present invention discloses a kind of rolling angular contact ball bearing, including bearing outer ring, bearing inner race, some big balls and little ball, between bearing internal external circle, set solid arranges that big ball and little ball, big ball and little ball interval are laid, the pure rolling angular contact ball bearing of the present invention, ball realizes pure rolling with bearing channel, bear linear velocity high, bearing capacity is big, and noise is little, reliability is high, life-span length.
Description
Technical field
The present invention relates to a kind of roll angular contact ball bearing, particularly pure rolling angular contact ball bearing.
Background technology
Angular contact ball bearing either with retainer or original full ball cannot solve ball and raceway groove sliding friction
Problem, the angular contact ball bearing with retainer causes ball and the slip of raceway groove to rub due to the friction between ball and retainer
Wipe, and the angular contact ball bearing of full ball is due to two neighboring ball stand under load simultaneously during work, when the two ball contacts, ball
It is increased dramatically with the frictional resistance of raceway groove, sliding friction occurs, particularly in high-speed overload, ball is easily worn and torn with bearing channel
Burn, service life are short, it is impossible to meet high demand.
The content of the invention
For the deficiencies in the prior art, the invention provides a kind of pure rolling angular contact ball bearing, ball and bearing channel
Pure rolling is realized, linear velocity is high, and bearing capacity is big, and noise is little, and reliability is high, life-span length.
To reach above-mentioned purpose, the present invention is achieved by the following technical solutions：
A kind of to roll angular contact ball bearing, which includes bearing outer ring, bearing inner race, some big balls and little ball, bearing
Arrange between Internal and external cycle that big ball and little ball, big ball and little ball interval are laid, large and small ball is without retainer.
Further, the diameter d2 of the little ball less than big ball diameter d1, wherein the value of d1-d2 be 0.01～
0.1mm。
Further, the gap s=0.01～0.15mm of the adjacent big ball and little ball.
The full ball angular contact ball bearing of the present invention, ball realize pure rolling with bearing channel, and coefficient of friction is little, the line for bearing
Speed is high, and bearing capacity is big, and noise is little, and reliability is high.
The application of pure rolling angular contact ball bearing of the present invention not only promotes metallurgy, electric power, building machinery, construction material, energy
The development of the industries such as source, moreover it is possible to meet the high-end fields such as automobile, wind-powered electricity generation, high-grade lathe, high ferro, Aero-Space and national defense and military
Using.
Description of the drawings
Fig. 1 is one front schematic view of the embodiment of the present invention.
Fig. 2 is embodiment of the present invention one side schematic diagram
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings：
Embodiment：Such as Fig. 1-2, a kind of rolling angular contact ball bearing, including bearing outer ring 1, bearing inner race 2, some big rollings
Pearl 3 and little ball 4, between bearing outer ring 1 and bearing inner race 2, set solid arranges big ball 3 and little ball 4, big ball 3 and little ball
4 intervals are laid, and big ball 3 and little ball 4 are without retainer.
Such as Fig. 1, the diameter d2 of the diameter d1 and little ball 4 of big ball 3, it is 0.01 that both diameter differences are the value of d1-d2
Foozle of the value scope of～0.1mm, d1-d2 much larger than ball, is through scientific design.The value of d1-d2 is too little, adjacent
Two balls simultaneously stand under load, ball are increased dramatically with the frictional resistance of raceway groove, the sliding friction for easily locking occur and producing；d1-
The value of d2 is too big, and little ball 4 is too big with the gap of raceway groove, play easily occurs, and noise is big, or even affects normal work.
Such as Fig. 1, size ball is to lay little ball 4 between two neighboring big ball 3 by small one and large one interval laying.Work
When making, each ball had not only revolved round the sun but also rotation, and due to the presence of diameter difference, big ball 3 is primarily subjected to load, as interval is laid, greatly
The sense of rotation of ball 3 is consistent, now the pure friction rolling of 3 stand under load of big ball, and coefficient of friction is little, although little ball 4 and big ball 3
The reverse rotation of CONTACT WITH FRICTION, but as not stand under load, coefficient of friction are little, it is nearly free from frictional resistance.Therefore, solve original full
As simultaneously stand under load causes the slip that the frictional resistance of ball and raceway groove is increased dramatically and occurs when ball angular contact ball bearing works
Friction problem.
As the gap s=0.01～0.15mm of Fig. 1, big ball 3 and little ball 4, gap are too little, ball is easily stuck, high
At once wear and tear during fast heavy duty burn；Gap is too big, and play easily occurs in ball, and noise is big, affects normal work.
The present invention solves the problems, such as that ball and raceway groove cannot realize pure rolling friction, by with NSK same model bearings
Contrast test, i.e., with same moment of torsion swivel bearing, test bearing rotational time：Present invention rotation stopped after 5.26 seconds, and NSK
Rotation stopped after 2.45 seconds, and its frictional resistance is substantially reduced, and under the operating mode of high-speed overload, effect is more significantly.
The present invention is applicable not only to single-row angular contact ball bearing, is also suitable, not only promotes on multiple row angular contact ball bearing
The development of the industries such as metallurgy, electric power, building machinery, construction material, the energy, moreover it is possible to meet automobile, wind-powered electricity generation, high-grade lathe, high ferro,
The application of the high-end field such as Aero-Space and national defense and military.
Described above, only using the embodiment of this origination techniques content, any those skilled in the art use this wound
Make done modification, change, all belong to the interest field of this creation opinion, and be not limited to those disclosed embodiments.
