Closed spiral rotating device and power transmission system

Abstract

The invention discloses a closed spiral rotating device and a power transmission system. The device comprises a closed shell, a propeller, a transmission shaft, a bearing, a piston assembly, a mediumin the closed shell, a power transmission system and the like, the piston assembly is composed of a piston cavity, a piston, a spring, a limiting block, a fluid inlet-outlet hole and the like. The piston assembly comprises a non-spring type piston assembly and a spring type piston assembly; the medium in the closed shell comprises water and gas. The propeller is installed in a closed shell with apiston assembly. The piston is mounted in a piston cavity reserved in the closed shell; one of two ends of the upper part of the piston extends out; a limiting block is mounted above the piston; a spring is mounted between the piston and the limiting block; the limiting block is provided with a fluid inlet and outlet hole, the propeller is installed in a set high-pressure closed shell, noise caused by the propeller can be lowered, the pressure difference between the upper surface and the lower surface of the propeller can be kept stable, and therefore when an airplane and the like operate at high altitude, the propelling force generated by the propeller can be kept stable, and high parameters can be kept.

Description

technical field [0001] The invention relates to a screw rotating device and a power transmission system, in particular to a propeller of a submarine, a submersible, an aircraft, an aerospace vehicle, etc., and a corresponding device and a power transmission system. Background technique [0002] Submarines and airplanes driven by propellers use the engine to provide continuous rotation power for the propellers, and the propellers push the fluid to obtain reaction force or pressure difference to generate lift and power. Working in the water body or the atmosphere has the following defects: the high-speed rotation of the propeller and the friction of the fluid and the noise caused by the operation of the engine will spread with the carrier to the surrounding; When working, the pressure of the working environment of the propeller is relatively low, and the low pressure will increase the idling degree of the engine and then affect the propulsion of the propeller. The reduction of...

[0002] Submarines and airplanes driven by propellers use the engine to provide continuous rotation power for the propellers, and the propellers push the fluid to obtain reaction force or pressure difference to generate lift and power. Working in the water body or the atmosphere has the following defects: the high-speed rotation of the propeller and the friction of the fluid and the noise caused by the operation of the engine will spread with the carrier to the surrounding; When working, the pressure of the working environment of the propeller is relatively low, and the low pressure will increase the idling degree of the engine and then affect the propulsion of the propeller. The reduction of the propulsion of the propeller will reduce the lift and running speed of the aircraft and submarine accordingly. Small; third, when the propeller is installed on the aircraft, its radar reflection area is relatively large, and when it is installed on a submarine and submerged in shallow seas, it will produce defects such as dragging mud and halo, which are not conducive to stealth
