Description
Technical field
The invention belongs to high-speed bearing technical field, especially a kind of hydrodynamic sliding bearing device with automatic cleaning function.
Background technique
Bearing needs good lubricating under operating condition, and particularly high-speed bearing, as the oil-impregnated bearing for hard disc of computer high-speed electric expreess locomotive, hydrodynamic sliding bearing etc.It is lubricated that oil-impregnated bearing provides lubricant oil to realize by oil-containing material to bearing, and these are lubricated along with long-term use meeting variation gradually, main cause: the condition that runs up lower bearing temperature raises, and lubricating oil viscosity declines, and deleterious is accelerated deterioration of lubricant; Bearing self wearing and tearing or extraneous dust infiltrate in lubricant oil, make bearing lubrication condition variation, even further aggravate the wearing and tearing of bearing, reduce the working life of bearing.
Can better provide lubricant oil by the oil-impregnated bearing that improves material at present, but effectively not improve for the temperature rise of the middle (center) bearing that runs up and the clean filtration of lubricant oil; Improved hydrodynamic lubrication bearing can local cooling, but effect is outstanding, and cannot play a role in filtering for the impurity in lubricant oil, affects the working life of bearing.
By retrieval, find 2 sections of Patents documents: (1) a kind of oil-containing---hydrodynamic pressure bearing (CN2898417Y), wherein, hydraulic bearing comprises oil-impregnated bearing cover, in oil-impregnated bearing cover, be provided with hole, the center hole of hole and oil-impregnated bearing cover is communicated with, and the inwall of this oil-impregnated bearing cover is provided with the lubricating fluid honeycomb ducts of two groups of inclinations, and two groups of lubricating fluid honeycomb ducts are about the axis face symmetry of bearing housing.In the utility model the cyclic process of lubricating fluid be one from cooling procedure, be conducive to like this retainer shaft rotating accuracy, improve working life of bearing.(2) a kind of bearing arrangement (CN102788038A) of a mechanical fluid couple drive supplying lubricating oil, wherein, bearing arrangement comprises outer ring, rolling element, flexible body, support, oil storage volume and is communicated with oil duct.Support is a circle ring parts, and indoor design has a circular hole, and outside is designed with the cylindrical support face of some; Flexible body is thin-wall circular lopps part, produces micro-elastic distortion when work, the inner headed face of flexible body and the supporting surface of support composition oil storage volume; Circumferencial direction along flexible body is provided with some for being connected the connection oil duct of oil storage volume and outer ring with axial direction; Rolling element is delivered to flexible body work loads and makes it that resiliently deformable occur; Outer ring is a rotation class part, and its inner headed face contacts with rolling element.The bearing arrangement of this Invention Announce utilizes the interaction between part, and flexible body is out of shape and produces harmonic motion, and the pressure of lubricant oil is changed, thereby lubricant oil is fed to friction surface through being communicated with oil duct.These two sections of patent middle (center) bearing structures do not have to realize the clean filtering function of lubricant oil, play the effect in working life of effective prolongation bearing.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of hydrodynamic sliding bearing with automatic cleaning function is provided, under bearing runs up condition, lubricant oil is provided and is continued good lubricating by automatic cycle, constantly bearing is lowered the temperature and lubricant oil is filtered simultaneously, not only ensure the cleanliness of lubricant oil, and effectively extended the working life of bearing.
The technical problem that the present invention solves takes following technological scheme to realize:
Have a hydrodynamic sliding bearing for automatic cleaning function, be made up of axle sleeve and stationary axle two-part, axle sleeve is connected with outer rotor, and stationary axle maintains static relatively, and sleeve lining is a smooth cylinder, and stationary axle cylindrical coordinates with axle sleeve.It is characterized in that: stationary axle outer surface has 5 translots and two groups of man type skewed slots, wherein two translots lay respectively at man type skewed slot point of intersection place, and another 3 translots just in time distribute alternately with two groups of man type skewed slots.
Stationary axle has the oil storage pool of hollow, and oil storage pool is connected by multiple oilholes with 5 translots of stationary axle outer surface.
Oil storage pool is divided into 5 sections by 4 filter screens, and supported and fixed by 5 filter screen stands, and every section all has oilhole to be connected with stationary axle outer surface translot, then by plug cock, oil storage pool sealed.
Advantage of the present invention and good effect are:
By axle sleeve and stationary axle sufficient lubrication, in oil storage pool, fill lubricant oil, when axle sleeve starts to turn to while running up along specific, under the effect of two man type skewed slots, utilize the hydrodynamic characteristic of minute groove, lubricant oil is flowed to man type skewed slot point of intersection place by center and outermost two translots respectively, and keeps stable.Position, man type skewed slot point of intersection oil pressure raises, lubricant oil can enter in oil storage pool by entering oilhole, oil storage pool enters the pressure rising meeting of oilhole place to two side flow, lubricant oil filters automatically by filter screen, flow out oil storage pool through both sides oil outlet again, flow in the translot of stationary axle surface, under the effect of two man type skewed slots, the lubricant oil on stationary axle surface can constantly flow to position, man type skewed slot point of intersection, go round and begin again, form the two cover circulatory systems, the circulation of this lubricant oil is conducive to keep the transient equiliblium of lubricant oil, greatly improve the rotation precision of axle sleeve.
The present invention is a kind of simple in structure, design science, safe and reliable, the practical hydrodynamic sliding bearing with automatic cleaning function, under bearing runs up condition, lubricant oil automatic cycle provides and continues good lubricating, constantly bearing is lowered the temperature and filtration simultaneously, ensure the cleanliness of lubricant oil, effectively extend bearing working life.
