Technical field
The present invention relates to technical field of bearings more particularly to a kind of bearings of anti-suck fluid.
Background technology
Bearing is for determining rotary shaft and other parts relative motion position, playing the parts of bearing or guiding role.
The major function of bearing is supporting rotating shaft or other movable bodies, guides rotation or moving movement and bears by axis or parts on shaft
The load being transmitted to.Bearing has been base parts and components indispensable in contemporary mechanical equipment, is answered in national economy every profession and trade
With very extensive, its precision, performance, life and reliability play the precision, performance, life and reliability of host decisive
Effect.
According to the difference of the friction properties of the moving elements, bearing can be divided into rolling bearing and sliding bearing two major classes.Wherein roll
Bearing is generally made of outer ring, inner ring, rolling element and four part of retainer, is strictly speaking by outer ring, inner ring, rolling element, guarantor
Hold frame, sealing, six big part of lubricating oil composition.In simple terms, it may be defined as long as having outer ring, inner ring, rolling element to roll
Bearing.By the shape of rolling element, rolling bearing is divided into ball bearing and roller bearing two major classes.
It is a kind of 201320265239.2 bearings announced according to Chinese Patent Application No., including in outer race and bearing
Ring is equipped with ball between the outer race and bearing inner ring, which is radially equipped with an at least lubrication channel, in bearing
Ring is equipped with an at least lubrication hole in an axial direction, which is connected with lubrication channel, and the ball is hollow-core construction.This structure
Bearing is by offering lubrication channel, although its lubricant effect can be improved, fluid is entered by lubrication channel in bearing cavity
When portion, it is susceptible to fluid suck-back, to cause lubricant effect and heat dissipation performance to reduce.
Invention content
The present invention provides a kind of bearing of anti-suck fluid to overcome deficiency in the prior art.
The present invention is achieved through the following technical solutions：
A kind of bearing of anti-suck fluid, including bearing outer ring, bearing inner race, bearing outer ring cooperate with bearing inner race,
Multiple balls are installed, on retainer, adjacent ball is connected ball sleeve by retainer between bearing outer ring and bearing inner race
It is connected together, the ball grooves for installing ball is offered on the bearing inner race, lubricating oil is offered on the bearing inner race
The section in road, the oil leab is trapezoidal, and the big one end of oil leab diameter is oil inlet, the small one end of oil leab diameter
For oil outlet；And it is internally provided with filter plate in the oil leab, spring, the bullet are installed on the inner wall of the filter plate
One end of spring is connected with steel ball.
As the preferred technical solution of the present invention, which further includes left side dust-proofing ring and right side dust-proofing ring, the left side
Dust-proofing ring is mounted in left side cavity between bearing outer ring and bearing inner race, the right side dust-proofing ring be mounted on bearing outer ring and
In right side cavity between bearing inner race.
As the preferred technical solution of the present invention, the elastic stiffness of the spring is smaller.
As the preferred technical solution of the present invention, the outer wall of the filter plate is mounted on the inner wall of the oil leab,
And the filter plate is made of stainless steel.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is by being provided with oil leab, oil leab
Larger diameter end be oil inlet, smaller diameter end is oil outlet, and is equipped with filter plate inside the oil leab, can to profit
Lubricating oil liquid is filtered, and prevents the impurity in lubricating oil from causing to wear to ball, while by being provided with spring, spring it is rigid
Degree is smaller, and spring is connect with steel ball, and steel ball can be sealed the smaller diameter end of oil leab, prevent in bearing working mistake
Cheng Zhong, lubricating oil are flowed out from oil leab, generate suck-back phenomenon.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Referring to Fig. 1, Fig. 1 is the structural diagram of the present invention.
A kind of bearing of anti-suck fluid, including bearing outer ring 1, bearing inner race 2, bearing outer ring 1 and bearing inner race 2
It cooperates, multiple balls 3 is installed between bearing outer ring 1 and bearing inner race 2, ball 3 is sleeved on retainer 4, adjacent
Ball 3 is linked together by retainer 4, and the ball grooves 5 for installing ball 3, the axis are offered on the bearing inner race 2
Hold and offer oil leab 6 on inner ring 2, the section of the oil leab 6 be it is trapezoidal, the big one end of 6 diameter of oil leab be into
Hydraulic fluid port, the small one end of 6 diameter of oil leab are oil outlet；And it is internally provided with filter plate 7, the mistake in the oil leab 6
Spring 8 is installed on the inner wall of filter plate 7, the elastic stiffness of the spring 8 is smaller, and one end of the spring 8 is connected with steel ball 9,
