Abstract
The invention discloses a hydrostatic sliding bearing with one or more movable pads and relates to the field of sliding bearings. The hydrostatic sliding bearing with one or more movable pads comprises a bearing body, wherein one or more oil cylinders are arranged on the bearing body; a piston is arranged in each oil cylinder; each piston extends in the radial direction of the bearing body, and hydrostatic pads are in supporting connection with the tail end of the piston; an oil supply hole is formed in each oil cylinder; and a throttle is arranged on each piston. By adoption of the hydrostatic sliding bearing provided by the invention, the bearing position and the radial clearance can be controlled, so that the bearing neck position can be controlled within a relatively wide range, and then the bearing neck vibration abatement or a special axis motion orbit can be realized.
Description
Technical field
The present invention relates to sliding bearing field, be specifically related to a kind of mobile watt static-pressure sliding bearing.
Background technology
Sliding bearing is widely applied in rotating machinery, can be divided into hydrodynamic sliding bearing, static-pressure sliding bearing and hybrid sliding bearing by operation principle.Wherein, hydrostatic bearing has good control characteristic.At industrial circle, the application scenario that bearing characteristics is controlled gets more and more, for instance the monitor in real time that vibration characteristics and the stability of large rotating machinery are carried out, the compensation improving machine tool rotary precision controls.Along with the application of round surface non-in mechanical field gets more and more, such as the variation ellipse skirt section of electromotor, horn mouth special pinhole etc., the processing to this kind of curved surface, require again revolution axle journal is carried out oval axle center TRAJECTORY CONTROL.
Current hydrostatic bearing, it is all by changing oil pocket Stress control axle journal position, the radius clearance of bearing and axle journal can not change, and range of accommodation is confined in the interstice coverage of bearing, is restricted needing the occasion that main spindle's is adjusted in a big way.
Summary of the invention
The technical problem to be solved in the present invention is to provide one and can position of bearings and radius clearance be controlled, the movement watt static-pressure sliding bearing of vibration suppression or special axes movement locus to realize axle journal.
For solving above-mentioned technical problem, the present invention provides technical scheme as follows:
A kind of mobile watt static-pressure sliding bearing, including bearing body, described bearing body is provided with at least one oil cylinder, it is provided with piston in described oil cylinder, described piston is along the radial direction of described bearing body and stretches end bearing and is connected to static pressure tile fragment, described oil cylinder is provided for oilhole, described piston is provided with reducer.
Further, the surface configuration of described static pressure tile fragment has and the static-pressure oil chamber of described reducer UNICOM.
Further, described oil cylinder and static pressure tile fragment are multiple and are evenly arranged on described bearing body.
Further, the quantity of described oil cylinder and static pressure tile fragment is 2-8.
Further, described reducer is capillary tube.
Further, described reducer is aperture.
Further, described static pressure tile fragment has at least a way moving under the drive of piston, and all the other are fixed.
The method have the advantages that
Compared with prior art, the movement watt static-pressure sliding bearing of the present invention is in the course of the work, pressure oil enters oil cylinder from oil supplying hole, enter in static pressure tile fragment through throttle orifice, form bearing capacity, in oil cylinder under the effect of oil pressure thrust and bearing capacity, piston can with the dynamic and static pressure tile fragment radial direction way moving along bearing body, it is achieved that the adjustment to position of bearings and gap.The present invention can be used for the control to axle journal position, to realize the vibration suppression to axle journal or the motion of special orbit of shaft center.
Accompanying drawing explanation
Fig. 1 is the structural representation of the movement watt static-pressure sliding bearing of the present invention.
Detailed description of the invention
For making the technical problem to be solved in the present invention, technical scheme and advantage clearly, it is described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The present invention provides a kind of mobile watt static-pressure sliding bearing, as shown in Figure 1, including bearing body 1, bearing body 1 is provided with at least one oil cylinder 3, piston 4 it is provided with in oil cylinder 3, piston 4 is connected to static pressure tile fragment 2 along radial direction and the end bearing of bearing body 1, oil cylinder 3 is provided for oilhole 5, piston 4 is provided with reducer 6.
The movement watt static-pressure sliding bearing of the present invention is in the course of the work, pressure oil enters oil cylinder 3 from oil supplying hole 5, enter in static pressure tile fragment 2 through reducer 6, form bearing capacity, in oil cylinder 3 under the effect of oil pressure thrust and bearing capacity, piston 4 can with the dynamic and static pressure tile fragment 2 radial direction way moving along bearing body 1, it is achieved that the adjustment to position of bearings and gap.The present invention can be used for the control to axle journal position, it is achieved vibration suppression or the special axes movement locus to axle journal.
As a modification of the present invention, the surface of static pressure tile fragment 2 can be provided with and the static-pressure oil chamber 7 of reducer 6 UNICOM.Pressure oil enters oil cylinder 3 from oil supplying hole 5, enters static-pressure oil chamber 7 through reducer 6, forms bearing capacity.
Preferably, oil cylinder 3 and static pressure tile fragment can be multiple and be evenly arranged on bearing body 1.And the quantity of oil cylinder 3 and static pressure tile fragment can be 2-8.
Further, reducer 6 can be capillary tube, it is also possible to for orifice restriction, to realize the flow-control to the pressure oil entered in static-pressure oil chamber 7.As the another kind of improvement of the present invention, static pressure tile fragment 2 have at least one can under the drive of piston 4 way moving, all the other can be fixed.This control mode to static pressure tile fragment 2 way moving, it is possible to achieve the rectilinear movement in axle center, can realize the curvilinear motion in axle center equally.
The above is the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from principle of the present invention; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
