Abstract
The present invention belongs to mechanical manufacture, which concretely relates to a bearing device, and the bearing device adopts dynamic and static pressure technology; a bearing sleeve is arranged on a bearing, and is a rotary sleeve, and an oil film layer is arranged between a fixing seat and the bearing sleeve, and between the bearing sleeve and a shaft. When a rotating sleeve rotates at a high speed, stable dynamic pressure is generated between the rotating sleeve and the shaft, and between the rotating sleeve and the fixing seat, thereby reducing the vibration of the shaft, reducing abrasion and friction and enhancing the rigidity and the precision of the shaft. The present invention is especially suitable for occasions where a shaft can only rotate at a low speed, but the requirements of the rigidity and the precision of the shaft are very high, such as the output shaft of a worm wheel gearbox.
Description
Technical field
The invention belongs to the mechanical manufacturing method class, specifically is a kind of method of controlling static-pressure sliding bearing.
Background technique
Static-pressure sliding bearing is an a kind of bearing that reduces friction and wear, raising axle kinematic accuracy by the pressure of the liquid (gas) between axle and bearing layer.In the very high occasion of some rigidity required precisions, the technology that adopts active and static pressure to combine utilizes drive unit to make axle produce high speed rotating, the axle of high speed rotating and oil (gas) rete between the bearing produce stable kinetic pressure, to reduce vibration, reduce wearing and tearing, and improve the rigidity and the precision of axle greatly.But also there is certain narrow limitation in this dynamic and hydrostatic bearing, in some special occasion, axle does not allow high speed rotating and can only make low speed rotation the time (as the output shaft of worm wheel gearbox), when if the rigidity of requirement axle and precision are very high again, the method that existing general employing high-speed rotating shaft produces active and static pressure just can not be used.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, disclose a kind of method of controlling static-pressure sliding bearing, it makes it to rotate by the live axle bearing sleeve and produces stable active and static pressure, thereby reduces vibration, improves the rigidity and the precision of axle.
The present invention realizes in the following manner:
A kind of method of controlling static-pressure sliding bearing, described static-pressure sliding bearing comprises a rotatable bearing housing, between bearing fixed seat and bearing housing, bearing housing and axle, be provided with oil lamella, it is characterized in that: use a drive motor to drive the bearing housing rotation, to produce stable active and static pressure.
During bearing housing high speed rotating of the present invention, because between bearing housing and the axle, produce stable kinetic pressure between bearing housing and the bearing fixed seat, thereby reduce the vibration of axle, reduce and wear and tear.
A kind of method of controlling static-pressure sliding bearing of the present invention also can be between bearing housing and axle, between bearing housing and the bearing fixed seat air film layer is set.
The present invention adopts the active and static pressure technology, between bearing fixed seat and bearing housing, bearing housing and axle oil lamella or air film layer is set, and the bearing housing by high speed rotating is to produce the steady dynamic static pressure.Between general state lower shaft and bearing housing, be static pressure between bearing housing and the bearing fixed seat, when in case of necessity, drive motor drives the bearing housing rotation, makes and produces stable kinetic pressure between axle and bearing housing, bearing housing and fixed base, thereby reduce the vibration of axle, reduce wearing and tearing.Can only do under the situation of low speed rotation (as the output shaft of worm wheel gearbox) at some, use the present invention can reach good effect.
Description of drawings
The bearing means structural representation that Fig. 1 makes for the inventive method.
