Abstract
The invention discloses an airplane takeoff assisting system of a marine worm and wormwheel device. The assisting system is a pure mechanical system and does not need energy form conversion and an energy storage device. The feature of interconverting rotary motion and linear motion by the worm and wormwheel device is applied to convert the mechanical rotary motion of a marine main engine into the mechanical linear motion of an assistor; the feature that drive, slave drive and self-lock of the worm and wormwheel device are irreversible is applied to resist the negative feedback force of setback acceleration on the assistor when an airplane takes off.
Description
Technical field: the present invention relates to a kind of peculiar to vessel, that utilize marine main engine power system energy, system that worm and wormwheel device boosting is taken off.
Technical background: existingly peculiar to vesselly take off assist system, be utilize steam expansion to promote piston to produce thrust, or electrical energy drive linear electric motors produce thrust, boosting is taken off.
Summary of the invention: the present invention be to provide a kind of peculiar to vessel, worm and wormwheel device, use marine main engine power system energy, by power-transfer clutch and gear arrangement transferring energy, boosting terminal velocity is adjustable set take off assist system.
Existing steam piston assist system, needs the boiler (if main frame is not steam turbine) independent of marine main engine and steam stowage arrangement, steam cylinder piston system; Existing linear electric motors assist system, needs electrical generator and capacitor-discharge device, linear induction motor system.If boiler or electrical generator can share with marine main engine, but due to centralized release energy during boosting, at least need independently energy storage device.The present invention does not need independently power system, but shares with marine main engine system.The present invention does not need independently energy storing device yet, and ship power system self can provide powerful instantaneous mechanical kinergety.Existing steam piston boosting, or linear electric motors boosting are relative complex and accurate system.Power-transfer clutch of the present invention, gear arrangement and worm and wormwheel device are pure mechanicals device, relatively simple and inaccurate, and the comparing reliability of pure mechanical device is higher, are more suitable for working environment and the state of upheaval on boats and ships.Assist system of the present invention, is the energy delivery system of pure machinery, does not need the conversion of form of energy, can directly be provided by ship power system.When taking off, the boats and ships of tens thousand of tons full speed ahead under marine engine full power promotes, and engine system possesses enough large rotor inertia, meets assist system energy requirement now.
Accompanying drawing illustrates: Fig. 1 is system flowchart of the present invention.
Detailed description of the invention: first the requirement to change-speed box is described, this change-speed box is electrodeless adjustable speed change-speed box, and this type of change-speed box has been applied on some automobile at present, and principle does not have problems.The pre-set different gear of this change-speed box, to adapt to acceleration/accel and the rate request of different aircraft accelerated take-off.Task of the present invention completes as follows, as Fig. 1, when aircraft needs accelerated take-off, change-speed box entered shelves on the gear of correspondence.At this time, in this work system, the rotating speed r of steamer host work
1determine, boosting distance AB determines, the tooth pitch of worm and wormwheel is determined, the linear velocity that B point is crossed in this kind of aircraft accelerated take-off is determined, the linear acceleration of boosting process is determined.Another two important working parameters in this work system can be determined thus: the time t of B point crossed by worm gear
2, and the rotating speed r of worm screw when B point crossed by worm gear
2.During accelerated take-off work, t
1moment power-transfer clutch closes, and is r by rotating speed
1main frame moment of torsion pass to t
1moment rotating speed is the transmission input C of zero, through the electrodeless variable-speed of change-speed box, at regulation moment t
2it is r that transmission output D obtains rotating speed
2moment of torsion export, by the driving device of 1: 1 transmitting ratio, by t
1to t
2time, D end are from zero to r
2rotary torque pass to worm and wormwheel device, worm and wormwheel device converts rotary motion to straight-line motion, and worm gear moves to B point from A point, and reaches required linear velocity, completes accelerated take-off.
T simultaneously
2spacing and the braking of time trigger system, disengaging of clutch, worm screw stops operating.The transmission self-locking had due to worm and wormwheel device and irreversible feature, namely wrom tooth spiral angle determines that the active of worm and wormwheel is driven.In this device, setting rotary motion is active movement, and straight-line motion is driven motions.After worm screw stops operating, the follow-up straight line setback acceleration taken off of aircraft can not transmit back system, can not affect the follow-up of aircraft and take off.If necessary, can, in the outer end of worm screw B point, one section be stayed not have threaded empty screw rod, just in case in spacing and disengaging of clutch all lost efficacy, make worm screw dally, and be unlikely to generation push rod accident.
Claims (1)
1. one kind directly uses that marine main engine mechanokinetic is peculiar to vessel takes off assist system, it is characterized in that marine main engine power is by power-transfer clutch, buncher, worm and wormwheel device, main frame Rotational mechanical movement is converted to linear mechanical motion, and boosting is taken off.
