Description
Technical field
The invention belongs to high-speed bearing technical field, especially a kind of hydrodynamic sliding bearing dress with automatic cleaning function
Put.
Background technology
Bearing needs good lubrication, particularly high-speed bearing under operating condition, is such as used for hard disc of computer electricity at a high speed
The oiliness bearing of machine, hydrodynamic sliding bearing etc..Oiliness bearing provides lubricating oil to realize lubrication by oil-containing material to bearing, this
A little lubrications can gradually be deteriorated with long-term use, main cause：Bearing temperature is raised under the conditions of running at high speed, under lubricating oil viscosity
Drop, effect is deteriorated, and accelerates deterioration of lubricant；Bearing itself is worn and torn or external dust is penetrated into lubricating oil, makes bearing lubrication condition
It is deteriorated, or even is further exacerbated by the abrasion of bearing, reduces the service life of bearing.
Lubricating oil can be preferably provided by improving the oiliness bearing of material at present, but for the middle (center) bearing that runs at high speed
Temperature rise and the cleaning of lubricating oil filtering are efficiently modified；Improved hydrodynamic lubrication bearing can be with local cooling, but effect is simultaneously
Do not protrude, and can not be played a role in filtering for the impurity in lubricating oil, influence the service life of bearing.
By retrieval, 2 Patents documents are found：(1) a kind of oil-containing --- hydrodynamic pressure bearing (CN2898417Y),
Wherein, hydrodynamic bearing includes being provided with hole in oiliness bearing set, oiliness bearing set, and hole connects with the centre bore that oiliness bearing covers
Logical, the inwall of oiliness bearing set is provided with two groups of inclined lubricating fluid honeycomb ducts, and two groups of lubricating fluid honeycomb ducts are on bearing
The axis face of set is symmetrical.In the utility model the cyclic process of lubricating fluid be one from cooling procedure, be so conducive to keep
The rotating accuracy of axle, the service life for improving bearing.(2) a kind of mechanical fluid coupling driving supplies the bearing arrangement of lubricating oil
(CN102788038A), wherein, bearing arrangement includes outer ring, rolling element, flexible body, supporter, oil storage volume and connects oil duct.
Supporter is a circle ring parts, and indoor design has a circular hole, and exterior design has a number of cylindrical support face；Flexible body
For thin-wall circular ring parts, small elastic deformation is produced during work, the inner headed face of flexible body and the supporting surface composition of supporter are stored up
Oily volume；Along the circumferentially and axially direction of flexible body be provided with it is some be used to connecting oil storage volume and outer ring connect oil
Road；Service load is delivered to flexible body and brings it about elastic deformation by rolling element；Outer ring is a rotation class part, its inner headed face
Contacted with rolling element.The bearing arrangement of the Invention Announce utilizes the interaction between part, and flexible body deforms and produces harmonic wave
Motion, makes the pressure of lubricating oil change, so that lubricating oil is fed to friction surface through connecting oil duct.In this two patents
Bearing arrangement plays a part of effectively extending bearing service life without that can realize the cleaning filtering function of lubricating oil.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art there is provided a kind of dynamic pressure sliding axle with automatic cleaning function
Hold, under the conditions of bearing runs at high speed, lubricating oil is provided by automatic cycle continues good lubrication, while constantly entering to bearing
Row cools and lubricating oil is filtered, and not only ensure that the cleanliness factor of lubricating oil, and effectively extends the use longevity of bearing
Life.
Present invention solves the technical problem that taking following technical scheme to realize：
A kind of hydrodynamic sliding bearing with automatic cleaning function, is made up of axle sleeve and fixing axle two parts, axle sleeve with it is outer
Rotor is connected, and fixing axle is then relatively fixed motionless, and sleeve lining is a smooth cylinder, and fixing axle is cylindrical to match somebody with somebody with axle sleeve
Close.It is characterized in that：There are 5 translots and two groups of herringbone skewed slots in fixing axle outer surface, and two of which translot is located at herringbone respectively
Shape skewed slot intersection, another 3 translots just distribute alternately with two groups of herringbone skewed slots.
Fixing axle has hollow oil storage pool, and oil storage pool is connected with 5 translots of fixing axle outer surface by multiple oilholes
It is logical.
Oil storage pool is divided into 5 sections by 4 pieces of screen packs, and is supported fixation by 5 filter screen stands, and every section has oilhole
It is connected with fixing axle outer surface translot, then is closed oil storage pool by plug cock.
Advantages and positive effects of the present invention are：
By axle sleeve and fixing axle sufficient lubrication, lubricating oil is filled in oil storage pool, when axle sleeve starts to transport at a high speed along specific steering
When turning, under two herringbone skewed slot effects, using the hydrodynamic characteristic of minute groove, lubricating oil is respectively by center and outermost
Two translots of side flow to herringbone skewed slot intersection, and keep stable.The oil pressure rise of herringbone skewed slot crosspoint position,
Lubricating oil can be entered in oil storage pool by entering oilhole, and oil storage pool, which enters pressure rise at oilhole, to be flowed to both sides, and lubricating oil passes through
Screen pack is filtered automatically, then flows out oil storage pool by both sides oil outlet, is flowed into the translot of fixing axle surface, in two people
In the presence of font skewed slot, the lubricating oil on fixing axle surface constantly can flow to herringbone skewed slot crosspoint position, go round and begin again,
Two sets of circulatory systems are formed, the circulation of this lubricating oil is conducive to keeping the dynamic equilibrium of lubricating oil, greatly improves turning for axle sleeve
Dynamic precision.
The present invention is a kind of simple in construction, design science, safe and reliable, practical moving with automatic cleaning function
Sliding bearing is pressed, lubricating oil automatic cycle, which is provided, under the conditions of bearing runs at high speed continues good lubrication, while constantly to axle
Hold and cooled and filtration, it is ensured that the cleanliness factor of lubricating oil, effectively extension bearing service life.
