Abstract

PURPOSE:To improve the efficiency of power transmission through reducing resistance and loss of heat by forming a closed circuit circulating a compressor driven by a power shaft and a rotary machine driven by gas pressure and filling the closed circuit with the light gas such as helium and the like. CONSTITUTION:A closed circuit of fluid is formed by connecting the exhaust side of a compressor 2 driven by a power shaft 1 to the air intake side of a rotary machine 3 driven by the fluid pressure and also connecting the air intake side of the compressor 2 to the exhaust side of the rotary machine 3 by means of air introducing pipes 4, 5 respectively. The closed circuit is filled with light gas such as helium, hydrogen and the like as a medium for power. Further, an air separator 6, pressure absorption tank 7 and a gas replenishment device 9 are provided in the middle of the air introducing pipe 5. At the time of letting the light gas flow through driving the compressor 2 and transmitting the rotatory power to the rotary machine 3 by means of this device, improvement of efficiency as the power transmission device can be attained due to slight resistance and loss of heat because the medium is a light gas.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that uses gas as a power medium to transmit power.

Conventional work equipment A rotary machine consisting of an air motor is often used due to its lightweight characteristics, but air becomes high temperature when compressed by a compressor, and this heat is lost, resulting in a loss of power. .

In addition, self-cooling occurs due to expansion within the motor, and the volume and pressure ratio do not increase, resulting in considerably poor energy efficiency.

According to the present invention, the heat loss due to adiabatic compression and adiabatic expansion of helium is approximately 70 inches per the same volume of air, and the intake air of the compressor is filled with gas cooled by the adiabatic expansion book inside the rotating machine, resulting in significant efficiency. It will be an improvement.

Also, air is quite heavy.1. gg/A'), and for this reason, during high-speed operation, the exhaust from the exhaust port was blocked by its own inertia, and the high-speed movement of the motor was blocked, but helium weighs about 14 inches. This makes high-speed movement possible. According to experiments, 2
The one with 9100 rpm became 368.00 rpm with helium. If you include the increase in torque, the output will increase by about 50%.

The present invention will be described in detail below based on the drawings.

1 is a driving shaft, 2 is a compressor installed so as to be driven by the driving shaft 1, and 3 is a rotary machine driven by fluid pressure, and its shaft 3' is a passive shaft, that is, the power transmitted from the driving shaft 1 to the passive shaft I. Related to transmission devices.

4. The exhaust side of the compressor 2 and the intake side of the rotating machine 3, and the intake side of the compressor 2 and the exhaust side of the rotating machine 3, etc., are connected to each other.4. -5 to form a closed fluid circuit surrounding the compressor 2 and rotating machine 3.
The closed circuit is filled with helium, a lightweight gas, as a power medium.

In addition, an air separator 6 and a pressure absorption tank 7 are installed in the middle of the air guide pipe 5.
, there are embodiments in which a gas replenishment device 9 is further provided.

In the figure, 8 is a pressure regulating valve, 10 is an air buffer tank, 11.12
．． 13 is a pulp, 14.15 is a joint, and the air separator 6 gives a rotating flow to the power medium and when air is mixed in the medium, the medium is a light gas, so the heavy air is separated. - It is constructed so that it moves toward the outer periphery and is pulled out from the pulp 13 by mental force.

According to the present invention, when the driving shaft 1 rotates to drive the compressor 2 and flow a lightweight gas to transmit rotational power to the rotary machine 3, since the medium is a lightweight gas such as hydrogen or helium, the inertia of the medium is Since the resistance is small and the heat generated is small, heat loss is small and a thermally closed circuit is formed, and the efficiency of the power transmission device is improved.

In addition, when equipped with 9C/111111 m 6 of air, the air can be removed to ensure stable operation, and when a gas replenishment device 9 is provided via the pressure regulating valve 8, the internal pressure can be maintained above a certain level. If the pressure absorption tank 7 is installed, the capacity of the low pressure part between the rotary machine 3 and the compressor 2 should be made sufficiently large. Even if gas flows in, it is well buffered and has the advantage of being able to replace the air guide pipe in the low-pressure section with one that has low pressure resistance.

In actual use, it is convenient to make the block A part into one unit and attach the rotary machine using joints 14 and 15.

Further, in the above-mentioned embodiments, helium was used as the lightweight gas, but the lightweight gas may be hydrogen or the like, or even a mixed gas of helium and hydrogen.
