Abstract
The invention relates to a dual-worm pair clearance eliminating device for realizing self-adaptive adjustment of a clearance eliminating damp. A clearance eliminating worm is meshed with a clearance eliminating worm; a worm bearing and a worm bracket support the clearance eliminating worm; a steel sleeve is connected with a flange disk to form a cylinder body; an axle is assembled with a right flange disk, an axle sleeve, a left flange disk, a bearing and a locking nut to form a cylinder piston, and connected with the clearance eliminating worm through a screw; a pressure sensor can respectively detect pressure of A and B oil cavities of the cylinder piston, an electromagnetic steering valve can control the oil supplies of oil cylinders A and B; the pressure oil provided by the power device controls pressure of an oil outlet through a proportional depressurizing valve; a central controller processes pressure signals of a load sensor and a pressure sensor, and controls the pressure of the proportional depressurizing valve; and thereby, the axial displacement of the cylinder piston is realized, and the purpose of self-adaptively adjusting the clearance elimination according to the load change is reached; meanwhile, the dual-worm pair clearance eliminating device also can play the function of eliminating the clearance when the worm pairs are rotated in positive and reverse directions.
Description
Technical field
The present invention relates to twin worm pair to disappear gap swirl gear, the backlash eliminating equipment particularly utilizing damping adaptive to adjust on the secondary swirl gear of the highi degree of accuracy twin worm of load variations.
Background technique
According to the transmission principle of worm gear pair, it is in the process of calibration, only has a lateral tooth flank of worm and worm wheel to contact, the opposite side flank of tooth because of processing or assembly error certainly exist gap.Although the twin worm pair of current employing disappears, by adjusting the axially displaced of gap worm screw that disappear, gap swirl gear can ensure that twin worm pair is gapless in the process of transmission, but the resistance that gap worm screw is axially displaced because promotion disappears is nonadjustable, the maximum case only needed according to load preloads, negative effect is brought to the transmission accuracy of swirl gear and working stability, also increases power loss simultaneously.
Summary of the invention
The object of this invention is to provide that a kind of structure is simple, principle is reliable, the backlash eliminating equipment of the gap damping adaptive adjustment that can realize disappearing according to load variations.
The technical solution adopted in the present invention is: a kind of secondary backlash eliminating equipment of twin worm of the gap damping adaptive adjustment that realizes disappearing, the gap that disappears worm screw and anti-backlash worm wheel are meshed, worm bearing and endless screw support support the gap worm screw that disappears, steel bushing is connected with flange plate and is combined into cylinder body, axle forms cylinder plug with right flange plate, axle sleeve, left flange plate, bearing and sealed nut phase Assembly, and be connected with the gap worm screw that disappears by screw, pressure transducer and respectively detection cylinder plug A, B oil pocket pressure, the charge oil pressure of hydraulic control system to A, B oil pocket controls.
Described hydraulic control system comprises solenoid directional control valve, solenoid directional control valve can control oil cylinder A and B chamber fuel feeding, the pressure oil passing ratio reduction valve that power plant provide realizes oil outlet Stress control, central control unit to load sensor and pressure transducer, pressure signal process, and the pressure of control ratio reduction valve.
The present invention has following beneficial effect:
The present invention is processed by the load signal of central control unit to load sensor, the pressure of comparative example reduction valve regulates simultaneously, thus the adjustment realized A, B oil pocket pressure, and the signal of pressure transducer can feed back to central control unit, reach the object of the axially displaced gap resistance self-adaptative adjustment that disappears of the gap worm screw that disappears be connected with cylinder plug.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is agent structure schematic diagram of the present invention;
In figure: the gap that disappears worm screw 1, anti-backlash worm wheel 2, worm bearing 3, endless screw support 4, right flange plate 5, steel bushing 6, axle sleeve 7, flange plate 8, sealed nut 9, axle 10, left flange plate 11, bearing 12, pressure transducer (13,14), solenoid directional control valve 15, proportional pressure-reducing valve 16, power plant 17, central control unit 18, load sensor 19.
The hydraulic fluid port of A, B pressure oil.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.
See Fig. 1, installation concrete in figure and Placement have, a kind of secondary backlash eliminating equipment of twin worm of the gap damping adaptive adjustment that realizes disappearing, the gap that disappears worm screw 1 and anti-backlash worm wheel 2 are meshed, worm bearing 3 and endless screw support 4 support the gap worm screw 2 that disappears, steel bushing 6 is connected with flange plate 8 and is combined into cylinder body, axle 10 and right flange plate 5, axle sleeve 7, left flange plate 11, bearing 12 and sealed nut 9 phase Assembly form cylinder plug, and be connected with the gap worm screw 1 that disappears by screw, pressure transducer 13 and 14 detects cylinder plug A respectively, B oil pocket pressure, hydraulic control system is to A, the charge oil pressure of B oil pocket controls.
Further, described hydraulic control system comprises solenoid directional control valve 15, solenoid directional control valve 15 can control oil cylinder A and B chamber fuel feeding, the pressure oil passing ratio reduction valve 16 that power plant 17 provide realizes oil outlet Stress control, the signal of central control unit 18 pairs of load sensors 19 and pressure transducer 13 and 14 processes, and the pressure of control ratio reduction valve 16.
Device specific works process of the present invention and principle are:
Steel bushing 6 and flange plate 8 are combined to form cylinder body, axle 10 forms cylinder plug with right flange plate 5, axle sleeve 7, left flange plate 11, bearing 12 and sealed nut 9 phase Assembly, and be connected with the gap worm screw 1 that disappears by screw, load signal is passed to central control unit 18 by load sensor 19, central control unit 18 realizes forward or the negative pressures control of comparative example reduction valve 16 by the pressure signal of processing pressure sensor 13,14, thus realize the axially displaced of cylinder plug, reach the object of the gap damping that to disappear according to load variations self-adaptative adjustment.Select left position (or the right position) work of solenoid directional control valve 15, (or left) to the right of the gap worm screw 1 that can realize disappearing is mobile, thus the gap effect that disappears all can played when realizing worm gear pair clockwise and anticlockwise.
