Abstract
The present invention discloses a kind of pure rolling deep groove 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 deep groove 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 deep groove ball bearing, belong to field of bearings.
Background technology
The deep groove ball bearing for either still expiring ball with retainer cannot solve the problems, such as ball and raceway groove sliding friction,
Deep groove ball bearing with retainer causes the sliding friction of ball and raceway groove due to the friction between ball and retainer, and expires ball
Deep groove ball bearing due to two neighboring ball simultaneously stand under load during work, when the two ball contacts, ball is rubbed with raceway groove
Wipe resistance to be increased dramatically, sliding friction occur, particularly in high-speed overload, ball and bearing channel easily wear and tear burn, use
Short life, 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 deep groove ball bearing, ball and bearing channel reality
Existing pure rolling, linear velocity are 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 deep groove ball bearing, which includes bearing outer ring, bearing inner race, some big balls and little ball, in bearing
Arrange between outer ring that big ball and little ball, big ball and little ball interval are laid, described 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 deep groove ball bearing of the present invention, ball realize pure rolling with bearing channel, and coefficient of friction is little, the linear speed for bearing
Degree is high, and bearing capacity is big, and noise is little, and reliability is high.
The application of pure rolling deep groove ball bearing of the present invention not only promotes metallurgy, electric power, building machinery, construction material, the energy
Etc. the development of industry, moreover it is possible to meet answering for the high-end fields such as automobile, wind-powered electricity generation, high-grade lathe, high ferro, Aero-Space and national defense and military
With.
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 deep groove ball bearing, including bearing outer ring 1, bearing inner race 2, some big balls 3
With little ball 4, big ball 3 and little ball 4, big ball 3 and the interval of little ball 4 cloth between bearing outer ring 1 and bearing inner race 2, are arranged
If 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 value 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, phase
Adjacent two balls stand under load simultaneously, ball are increased dramatically with the frictional resistance of raceway groove, the sliding friction for easily locking occur and producing；
The value of d1-d2 is too big, and little ball 4 is too big with channel gap, 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 to rub when ball deep groove ball bearing works
Wiping 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 4.56 seconds, and NSK
Rotation stopped after 2.18 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-groove grooved ball bearing, is also suitable on multiple row deep groove ball bearing, not only promote it is metallurgical,
The development of the industries such as electric power, building machinery, construction material, the energy, moreover it is possible to meet automobile, wind-powered electricity generation, high-grade lathe, high ferro, aviation
The application of the high-end field such as space flight 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.
