Abstract

The utility model provides a fluid pressure large threshold value reinforced driving device composed of a movable plate A, a fixed plate B and a shaft C which is connected with a motor through the plates A and B by a stepless speed changer. The fluid pressure large threshold value reinforced driving device has small volume and strong driving force. The fluid pressure large threshold value reinforced driving device can be used for the propeller such as the power equipment of the airplane, the train and the ship operated in the air and in the water.

Description

Fluid pressure large threshold value reinforced driving device

The utility model relates to a kind of fluid pressure actuator, and the big threshold value of especially a kind of hydrodynamic pressure is strengthened drive unit.

The Bernoulli law is pointed out: place the object of fluid, faster than reflecting surface, then fluid will produce the flow velocity power of lifting on surface faster of pointing to as the flow velocity of a certain surfactant fluid.The agent of this law is the propeller on the wing of aircraft and aircraft, naval vessel, and the two has no difference in essence.But the fluid dynamic of the wing, slurry has only when their mass motions and could produce, and generally with regard to material, the movement velocity on their upper and lower surfaces is identical, just because the curvature difference, just form the speed difference of fluid on upper and lower surface, thereby only by the decision of liquid speed difference, this has suppressed the performance of power to a great extent for generation fluid dynamic, fluid dynamic value.

The purpose of this utility model is fundamentally to abandon this negative phenomena, provides a kind of utilization to produce hydrokinetic device by the fluid pressure difference between dynamic and static relatively stress surface.

This fluid power plant is by moving plate A, decide plate B, axle C, stepless speed variator D and motor E constitute.

Further describe below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

As figure, moving plate A overlaps, overlaps with deciding the form of plate B with airtight or friction (being ball, roller, needle roller etc.), and A, B plate can be circular, also can be other shapes.The A plate can directly be connected with axle C, or is connected with axle C by indirect modes such as gear, chain, belts, with its rotation.The B plate invests the fluid dynamic reflecting surface of A plate by screw, tenon or other fixing device, does not move with A.An end and the A of axle C connect, and the other end then is connected with stepless speed variator D, and D is connected with motor E again since stepless speed variator D must, when not needing D, a C then passes through modes such as gear, chain, belt and is connected with motor E.

Like this, when engine-driving A rotated, the B plate was static, and fluid (as air) A relatively has speed, and relative B then speed is O.According to the Bernoulli law, the two must produce a fluid dynamic by B sensing A, and rotating speed is big more, and power is also big more, may ultimately reach an existing Bernoulli law maximum that application apparatus is beyond one's reach.

The big threshold value of this hydrodynamic pressure is strengthened drive unit and be can be applicable at air, hydrogymnastic advancing means, as the drive unit of aircraft, vehicle, boats and ships.Because the volume of this device is little, driving force is strong, for vehicle of ground motion and so on, can not be subjected to or be subjected to less landform, the influence of condition, and vehicle can be done universal rotation on the ground, this device also can substitute existing propeller device, and the vertical takeoff and landing that realizes jet plane.
