Abstract
The invention relates to a speed reducing mechanism for testing an underwater high-speed aircraft, comprising an outer sleeve, speed reducing plates, a spring, a pin puller and a pin shaft, wherein peripheral equipment is a control system; the even pairs of speed reducing plates are symmetrically distributed on the circumference of the outer sleeve, and are connected with the outer sleeve by rotary shafts; the side surfaces of the speed reducing plates are provided with small holes; the pin puller is arranged on the outer sleeve; simultaneously a movable pin of the pin puller is arranged in the small holes, is used for fixing the speed reducing plates and is connected with the control system; and one end of the spring is fixedly connected in the outer sleeve, and the other end of the spring is connected with the speed reducing plates in a butting manner. After the control system sends out an actuating signal, the pin puller actuates, the movable pin releases from the small holes at the side surfaces of the speed reducing plates, so that the speed reducing plates lose fixed support and expand quickly and synchronously under the action of the spring and head resistance of fluid, and the expanded speed reducing plates generate resistance so as to reduce the speed of the underwater aircraft.
Description
Technical field
The present invention relates to the test of a kind of underwater high-speed navigation device and use speed reduction gearing, belong to a kind of mechanical device structure field.
Background technology
Because underwater high-speed navigation device will have a wide range of applications in future, in the process of research underwater high-speed navigation device, need test by submarine navigation and verify, how reliable recovery high speed aircraft becomes the key technical problem that must consider in process of the test.When using rocket propulsion under water, the speed of underwater high-speed navigation device can reach more than the 100m/s, and is in stabilized conditions.At the navigation latter end, aircraft becomes unpowered inertia motion, moving situation is by the stable instability that becomes, at this moment, aircraft still is under the fair speed, and underwater high-speed navigation device is used to reduce high speed aircraft sub aqua sport speed exactly with speed reduction gearing, shortens underwater high-speed navigation device unsteady motion time and move distance, help safety, reliable recovery underwater high-speed navigation device, thereby obtain test figures.
Summary of the invention
The invention provides a kind of underwater high-speed navigation device test speed reduction gearing, this speed reduction gearing increases resistance under water by launching flap, can effectively reduce the kinematic velocity of underwater high-speed navigation device.
Speed reduction gearing is used in the test of a kind of underwater high-speed navigation device, comprises outer sleeve, flap, and torsion spring, pin drift and rotating shaft, external equipment is control system; Wherein: flap is even-even and symmetrical distribution on the circumference of outer sleeve, flap is connected with outer sleeve by rotating shaft, the flap side has aperture, pin drift is installed on the outer sleeve, simultaneously the movable pin of pin drift is contained in the aperture of flap side and is used for fixing flap, and movable pin links to each other with control system; Torsion spring one end is fixedly connected on outer sleeve inside, and the other end and conflict with flap is connected.
The position that speed reduction gearing is installed is before the power section of aircraft; For guaranteeing the intensity of flap, the thickness of flap is 1: 1 with the width ratio.
Mode of operation: after control system provides actuating signal, the pin drift action, movable pin is deviate from from the aperture of flap side, make flap lose fixed pedestal, flap is rapid synchronous expansion under the effect of torsion spring and fluid head resistance, the flap that launches produces resistance, makes the submarine navigation device reduction of speed.
Beneficial effect:
1. speed reduction gearing can symmetry launch: the flap symmetric arrangement of speed reduction gearing, and can symmetry launch, produce uniform resistance thereby launch the back, after launching, flap expansion process river is in stabilized conditions to keep aircraft.
2. speed reduction gearing can synchronous expansion: the actuating signal of speed reduction gearing is provided synchronously by control system, and flap launches simultaneously, guarantees that aircraft in moderating process, produces the moment of symmetry to aircraft.
