Abstract
A driving control sliding bearing is mainly formed by a bearing outer ring (1), a connection plate (2), position sensors (3), throttling holes (4), a piezoelectric ceramic actuator (5), throttling blocks (6), a spindle (7), a pipeline (8) and an oil pump (9). Four evenly distributed throttling holes (4) are processed on the bearing outer ring (1), and the piezoelectric ceramic actuator (5) and the throttling blocks (6) are arranged above the throttling holes (4), then the connection plate is arranged, four position sensors (3) are arranged on the bearing outer ring (1), and the spindle is arranged inside the bearing outer ring (1). The connection plate (2) is directly connected with a hydraulic pipe (8), and high pressure oil is provided through the oil pump (9). The driving control sliding bearing has the advantages of being compact in structure, low in cost, high in integration degree and the like and can be applied to the fields of machine tool industries, heavy industries, iron and steel industries and the like.
Description
Technical field
This invention belongs to mechanical transmission fields, particularly a kind of ACTIVE CONTROL sliding bearing.
Background technique
Sliding bearing is widely used in the large-scale rotating equipment of low-speed heave-load.Traditional picture east bearing accuracy is uncontrollable, and is therefore very high to accuracy of manufacturing and installation precision requirement, increased manufacture cost.At present; Filmatic bearing precision with active control function is largely improved, and the main path of ACTIVE CONTROL has: bearing shell is adjusted through the different driving mode in (1), changes outer race, interior annular shape; With the change oil clearance, but its adaptive ability is not enough; (2) adopt magnetic fluid, ER fluid fluid etc. to change fluid property, its control system more complicated; (3) adopt and to carry out the closed loop control bearing arrangement, but since highi degree of accuracy guiding valve and servovalve cost than higher, low-response, the control accuracy of small flow is low, not seen widespread use arrives industrial field.
Summary of the invention
The object of the invention is exactly the shortcoming that overcomes the above-mentioned background technology, and provides a kind of precision high ACTIVE CONTROL sliding bearing.
A kind of ACTIVE CONTROL sliding bearing involved in the present invention, this device mainly is made up of bearing outer ring 1, connecting plate 2, position transducer 3, throttle orifice 4, piezoelectric ceramic actuator 5, throttle block 6, main shaft 7, hydraulic pipe line 8, oil pump 9 and control circuit; Four throttle orifices 4 in the equal portion of bearing outer ring 1 processing, and, connecting plate 2 is installed then in that piezoelectric ceramic actuator 5 and throttle block 6 are installed above throttle orifice 4, at bearing outer ring 1 four position transducers 3 are installed, main shaft 7 is installed in the inside of bearing outer ring 1; Connecting plate 2 directly links to each other with hydraulic tube 8, through oil pump 9 high pressure oil is provided; During work, oil pump is carried 9 and is flow through pipeline 8, supplies high pressure oil through connecting plate 2 and throttle orifice 4 to the inner chamber of bearing outer ring 1; Promote main shaft 7 and overcome the outer effect of carrying, between main shaft 7 and bearing outer ring 1, form oil film, did the time spent in outer year when main shaft 7 receives changing; Squint in main shaft 7 positions; Position transducer 3 detects position offset and feeds back to control system, and control system is applied the change of control voltage for piezoelectric ceramic actuator 5 and presses driving throttle block 6 to move, change the size of throttle orifice 4; Control is regulated the position of main shaft 7 through the flow of the hydraulic oil of throttle orifice 4.
ACTIVE CONTROL sliding bearing of the present invention is on the filmatic bearing basis based on the capillary throttling, changes capillary diameter through intellectual materials such as piezoelectric constant, the closed loop control of adjustment throttling comparison filmatic bearing intelligence.It has compact structure, cost is low and the level of integration advantages of higher, and is applicable in fields such as machine tool industry, heavy duty industrial and Iron And Steel Industry.
