Abstract
The utility model discloses a kind of dynamic and hydrostatic bearing, it includes bearing body (1), circumferentially spaced on the medial wall of bearing body (1) it is provided with multiple work oil groove (2), it is characterized in that: the circumferentially arranged oil supply tank (3) having an annular on the medial wall of bearing body (1), the oil groove (2) that respectively works is connected with oil supply tank (3) respectively, and described bearing body (1) is provided with the fuel feed hole (4) for supplying oil supply tank (3) fluid.This utility model provides a kind of dynamic and hydrostatic bearing, and the blocking probability that its fuel feed hole occurs is low, thus reduces fault rate.
Description
Technical field
This utility model relates to the technical field of bearing, specifically a kind of dynamic and hydrostatic bearing.
Background technology
So-called dynamic and hydrostatic bearing refers under hydrostatic lubrication state, again can be in work under hydrodynamic lubrication state
The sliding bearing made.Owing to contacting between bearing with axle is fluid pressure, therefore without direct rigid contact, its resistance that rubs
Power is little, noise is low, for the abrasion of bearing and axle is little and service life is long, so being more and more applied to high-precision
In industrial processes, but dynamic and hydrostatic bearing to realize the active force depending primarily on each work oil groove for axle that works normally
Form balance, i.e. each work oil groove high pressure conditions to be kept, and meanwhile oil liquid pressure is low in oil feed line, thus be accordingly used in
The aperture of the fuel feed hole supplying each work oil groove is inevitable less, is i.e. realized the pressurize of work oil groove by aperture supply fluid, but
Be small-bore fuel feed hole again be susceptible to blocking, the especially work oil groove of the dynamic and hydrostatic bearing of prior art is the most more,
And the most each self-corresponding fuel feed hole that is provided with of each work oil groove, as long as wherein any one fuel feed hole generation blocking will be made
The work oil groove becoming corresponding lost efficacy, thus caused whole bearing normally to work, after more seriously axle one side tilts with
Bearing contacts firmly, causes axle and bearing to scrap, this reason that dynamic and hydrostatic bearing fault rate in industry is the highest the most just it
One.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of dynamic and hydrostatic bearing, the blocking that its fuel feed hole occurs
Probability is low, thus reduces fault rate.
Technical solution adopted in the utility model is: provide a kind of dynamic and hydrostatic bearing, and it includes bearing body, and bearing is originally
Circumferentially spaced on the medial wall of body it is provided with multiple work oil groove, it is characterised in that: on the medial wall of bearing body circumferentially
Being provided with the oil supply tank of an annular, each work oil groove is connected with oil supply tank respectively, and described bearing body is provided with for supplying
The fuel feed hole of oil supply tank fluid.
Being provided with an oil-recovery tank respectively between two work oil grooves of arbitrary neighborhood, oil-recovery tank deviates from the side of oil supply tank and is provided with
Fuel-displaced breach, for discharging the fluid in oil-recovery tank.
Described oil supply tank is positioned at bearing body and sequentially passes through along its length direction along self axial centre position, oil supply tank
Wear the sidewall of each work oil groove, be used for supplying work oil groove fluid.
Described oil supply tank is deeply more than the groove depth of work oil groove along bearing body radial slot.
Work oil groove is divided into two sub-oil grooves of symmetry by described oil supply tank, and two sub-oil grooves are respectively with oil supply tank even
Logical.
Described work oil groove is four, and four work oil grooves are uniformly distributed along the circumference of bearing body.
Described fuel feed hole is connected with oil supply tank by an aperture.
Described fuel feed hole is one.Single fuel feed hole is arranged, and decreases the risk of the fuel feed hole blocking of small-bore.
After using above structure, first dynamic and hydrostatic bearing of the present utility model compared with prior art has the advantage that,
This bearing uses macropore single oilhole oil-feed, compares traditional each oil pocket and joins fuel feed hole to have technique, assembling simple, and can
Well control temperature rise, secondly, each work oil groove can be carried out fuel feeding by oil supply tank.

Detailed description of the invention
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
This utility model provides a kind of dynamic and hydrostatic bearing, and it includes bearing body 1, along week on the medial wall of bearing body 1
To being arranged at intervals with multiple work oil groove 2, it is characterised in that: circumferentially arranged on the medial wall of bearing body 1 have an annular
Oil supply tank 3, each work oil groove 2 is connected with oil supply tank 3 respectively, and described bearing body 1 is provided with for supplying oil supply tank 3 fluid
Fuel feed hole 4.
Being provided with an oil-recovery tank 5 respectively between two work oil grooves 2 of arbitrary neighborhood, oil-recovery tank 5 deviates from the side of oil supply tank 3
It is provided with fuel-displaced breach 5.1, for being discharged by the fluid in oil-recovery tank 5.
Described oil supply tank 3 is positioned at bearing body 1 and depends on along its length direction along self axial centre position, oil supply tank 3
The sequential sidewall wearing each work oil groove 2, is used for supplying work oil groove 2 fluid.
Described oil supply tank 3 is deeply more than the groove depth of work oil groove 2 along bearing body 1 radial slot.
