Description

Air engine technology

The present invention relates to an engine, and more particularly to an air engine. Background technique

In the existing air engine, the crankshaft mechanism is used to drive the spindle to rotate, thereby achieving the driving purpose. The crank-link mechanism has a dead point position during the movement. When the crank-link mechanism is at the dead-end position, the transmission angle Y =0°, the force is perpendicular to the direction of motion, and the active member cannot move the follower.

For air engines, when the piston rod is in line with the connecting rod, it is the dead center position. During the operation of the air engine, the inertia of the mechanism is used to cause the piston rod to continue to move past the dead point. When the air engine is in the initial state at the dead point position, the initial velocity of the machine is zero. When there is no inertia, the inertia cannot be used to pass the dead point, so the air engine cannot be started.

Therefore, there is a need for an air engine that can prevent the air engine from being in a dead center position. Summary of the invention

As shown in Figures 1-3, the air motor of the present invention includes a body 100, a main shaft 200, a gas rainbow 300, a flywheel 400, a gas storage device 500, a control valve 600, and an angular displacement sensor (not shown). The air body 100, the main shaft 200, the gas rainbow 300, and the flywheel 400 constitute a driving device for the air engine of the present invention, and the gas storage device 500, the control valve 600 and the angular displacement sensor are used to control the operation of the driving device. more specific:

The body 100 has a lumen 100a, and the spindle 200 is rotatably coupled to the body 100 such that a portion of the spindle 200 is located within the lumen 100a. Specifically, bearings are symmetrically disposed on the two side walls of the body 100, and the main shaft 200 is disposed through the body 100 and rotatably coupled to the body 100 through bearings.

The flywheel 400 is located in the inner cavity 100a, and the flywheel 400 is fixedly coupled to the main shaft 200 through a connecting key, so that when the flywheel 400 rotates, the main shaft 200 is synchronously rotated. The side surface of the flywheel 400 is uniformly fixed with three abutting blocks 410, and the outer side surfaces 411 of the three abutting blocks 410 are disposed at an angle with the side surface of the flywheel 400, and the outer side surface 411 forms a driving surface. The three driving surfaces 411 are all disposed counterclockwise with respect to the flywheel 400 to ensure that both the main shaft 200 and the flywheel 400 rotate in a counterclockwise direction; of course, the three driving surfaces 411 can also be arranged clockwise with respect to the flywheel 400. At this time, the main shaft Both the 200 and the flywheel 400 rotate in a clockwise direction. Further, the driving surface 411 protrudes from the side of the flywheel 400.

The gas rainbow 300 has four, and four gas rainbows 300 are fixed on the side wall of the body 100. The gas rainbow 300 is evenly arranged around the flywheel 400, and the output end 320 of the gas rainbow 300 extends into the inner cavity 100a and abuts against the driving surface 411. Further, the central axis of the output end 320 of the gas rainbow 300 passes through the axis of the flywheel 400. The gas storage device 500 is equipped with a high-pressure gas, and the four gas-red devices 300 are respectively connected to the gas storage device 500, and the control valve 600 is respectively disposed on the connecting gas path of the four gas-red batteries 300 and the gas storage device 500. The angular displacement sensor measures the angular displacement of the rotation of the spindle 200, and controls the control valve 600 to be turned on or off according to the measured angular displacement amount, thereby controlling the output end 320 of the gas rainbow 300 to sequentially push the driving surface 411. Specifically, the radius of the flywheel at the end of any driving surface 411 and the radius of the flywheel at the starting end of the next driving surface 411 in the direction of rotation of the flywheel 400 form a first angle α, and the output ends of the adjacent two gas rainbows 300 A second angle β is formed between the radius of the flywheel of 320, and the first angle α is smaller than the second angle β. During the rotation of the flywheel 400, before the output end 320 of one cylinder 300 pushes a drive surface 411 to the end, the output end 320 of the adjacent other cylinder 300 begins to push the next drive surface 411.

Turning on or off; at least one control valve 600 is in an on state, the high pressure gas drives the gas rainbow 300 connected thereto, and the piston 310 drives the tetrafluoroethylene oil ring 310a and the tetrafluoroethylene piston ring 310b along the inner wall of the gas rainbow 300 Sliding, the driving output end 320 is outwardly extended to push the driving surface 411; the driving surface 411 is subjected to an urging force F passing through the axis of the flywheel 400, and a supporting force N perpendicular to the driving surface is generated on the driving surface 411. The pushing force F and the supporting force N generate a driving force f downward along the driving surface 411. Since the gas rainbow 300 is fixed, the driving force f drives the flywheel 400 to rotate in a direction opposite to the driving force f; the flywheel 400 drives the spindle 200 to rotate; The angular displacement sensor measures the angular displacement of the rotation of the spindle 200, and controls the four control valves 600 to be sequentially turned on or off according to the measured angular displacement amount, thereby controlling the gas rainbow 300. An output terminal 320 sequentially drives the push surface 411, such that the flywheel 400 has been output terminal 300 of the rainbow gas ejector 320 during rotation, so that the flywheel 400 and the spindle 200 continues to rotate.

And the first angle α formed between the radius of the flywheel at the end of any driving surface 411 and the radius of the flywheel at the beginning end of the next driving surface 411 in the direction of rotation of the flywheel 400 is smaller than the output end 320 of the adjacent two gas rainbows 300. The second angle β between the radius of the flywheel, during the rotation of the flywheel 400, the control valve 600 controls the four gas rainbows 300 to operate in sequence, when the output end 320 of the gas rainbow 300 pushes a driving surface 411 to the end, The output 320 of the adjacent cylinder 300 begins to push the next drive surface 411. The flywheel 400 is driven by the cylinder 300 at any time during the rotation. Thus, the air motor provided by the present invention does not have a dead center position, thereby preventing the air engine from starting.
