Abstract
The invention relates to an automatic clutch device with a constant-power flow direction. The automatic clutch device is used for a manual operation mechanism of an airplane cabin door and a manual manipulating device of a winch. At present, according to an automatic clutch device with the constant-power flow direction, a multi-wedge-block-pawl structure or a ratchet-wheel-pawl structure is commonly used, and a specific input end and a specific output end are included; when power is transmitted in the direction from the input end to the output end, wedge blocks are separated from a brake device, and a clutch spindle normally works to transmit power; but in the reverse-power transmission direction, the wedge blocks enter the brake position, the spindle keeps braking, and idling in the reverse-power transmission direction cannot be achieved; and the automatic clutch device has the beneficial effects of being simple in structure, light and small in size. The condition that a manual operation mechanism is dragged to rotate is avoided, non-work wear of most parts in the manual operation mechanism is reduced, the service life of the parts is prolonged, and economic benefits are obvious. Therefore, the automatic clutch device has the great economic application value.
Description
Technical field
The present invention relates to one and determine power flow direction automatic clutch device, for the operating mechanism of aircraft hatch door and the operating device of winch.
Background technology
Determine the automatic clutch device of power flow direction at present, the many voussoirs of general use or ratchet-pawl structures, there is specific input terminus and output terminal, when transmitting power (namely along power transimission positive dirction) along input terminus to output terminal, voussoir departs from braking position, and clutch spindle normal operation transmits power; But voussoir enters braking position when reverse power transmission direction, main shaft maintenance braking, idle running when reverse power transmits direction (one end keeps not moving) can not be realized by dragging rotation, one end.
Summary of the invention
Technical problem to be solved by this invention is: determine power flow direction automatic clutch device by provided by the invention, it is achieved unidirectional delivery power.
One determines power flow direction automatic clutch device, for realizing unidirectional power transimission, this device comprises right shell body, to top ripple spring, left shell, input shaft, angular contact bearing, steel ball, tunnel shaft, stiction sheet, movable friction plate, output shaft, needle roller thrust, maintenance frame component, thrust packing ring, axle sleeve, deep groove ball bearing and angular contact ball bearing, wherein
Described left shell and right shell body are bolted; The end of described input shaft has the annular shaft shoulder, this annular shaft shoulder end face, around circumferentially there being some tapered holes, input shaft is fixed in left shell at axle journal place by angular contact bearing; The middle part of described tunnel shaft has annular protrusion, has some tapered holes on an end face of this annular protrusion, corresponding with the tapered hole of the annular shaft shoulder; Steel ball is arranged between relative tapered hole; Another end face at described annular protrusion intersects suit stiction sheet and movable friction plate successively, with spline joint between tunnel shaft and movable friction plate, with spline joint between stiction sheet and output shaft; Output shaft and right shell body, axially by needle roller thrust, frame component and thrust packing ring position with keeping, are being located radial through deep groove ball bearing; To top ripple spring in the centre hole of described tunnel shaft, located by the step hole of axle sleeve, angular contact ball bearing and output shaft inside.
When oppositely inputting, output shaft and movable friction plate rotate, and due to the effect to top ripple spring, be separated, cannot transmit moment of torsion between movable friction plate with stiction sheet; When just to input, the tapered hole on input shaft can promote steel ball to do vertically and move by a small margin, is overcoming by two groups of friction plates compressions after to top ripple spring, and output shaft can move together along with input shaft.
Useful effect: use this automatic clutch device in the dynamo-electric formula aircraft hatch door actuation mechanism of manual input function possessing, have the advantages that structure is simple, weight is light, volume is little, effectively avoid manual flexible axle by dragging situation about rotating, decrease the non-service wear of the flexible axle overwhelming majority, extending the work-ing life of flexible axle, economic benefit is obvious. Therefore, the power flow direction automatic clutch device of determining of this type not passive rotation has very big Economic Application and is worth.
Accompanying drawing explanation
Fig. 1 is the structural representation of automatic clutch device of the present invention.
1. left shell; 2. deep groove ball bearing; 3. output shaft; 4. axle sleeve; 5. angular contact ball bearing; 6. pair top ripple spring; 7. thrust packing ring; 8. needle roller thrust and maintenance frame component; 9. stiction sheet; 10. movable friction plate; 11. tunnel shafts; 12. steel balls; 13. angular contact bearings; 14. right shell bodies; 15. input shafts
Embodiment
In the example depicted in figure 1, whole structure is included between left shell 14 and right shell body 1, and power only allows to be passed to output shaft 3 from input shaft 15. When action torque on output shaft 3 and rotating speed (no matter clockwise or counterclockwise), output shaft and movable friction plate 10 rotate by dragging, but due to the effect to top ripple spring 6, positive pressure is not had between movable friction plate 10 and stiction sheet 9, moment of torsion cannot be transmitted, namely stiction sheet 9 and input shaft 15 can not keep, and output shaft keeps by dragging idle running; When input shaft 15 initiatively running (no matter clockwise or counterclockwise), annular slope on input shaft 15 can promote steel ball 12 to do vertically and move by a small margin, after overcoming the resistance to top ripple spring 6 (only needing the stroke of 0.1～0.2mm), two groups of friction plates are compressed, output shaft can move together along with input shaft, and device can transmit moment along this direction.
