Description

Turbine with vane and rotor assembly

This application claims priority based on Korean Patent Application No. 10-2018-0161350 filed on December 13, 2018 and Korean Patent Application No. 10-2019-0027498 filed on March 11, 2019, above All content disclosed in the specification and drawings of the applications is included in the present application.

The present invention relates to a turbine having an assembly of vanes and rotors, and more particularly, to a turbine having an assembly of vanes and rotors having a structure in which the rotor rotates to generate rotational force due to fluid pressure.

Turbine is a device that converts the pressure of a working fluid, such as water, oil, gas, steam, etc. into rotational motion to perform various mechanical tasks, and is very useful for internal power conversion means of automobiles, generators, and engines.

Various structures are currently known as such turbines. In most turbines, a configuration in which a fluid pressure is converted into a rotational motion by a propeller is widely used. However, this method usually operates in such a way that fluid flows in and out perpendicularly to the rotating surface formed as the blades of the propeller rotate, so the efficiency is significantly lowered when the area of the rotating surface and the flow area of the fluid do not match. There is a problem, and there is a vulnerability in that the flow of the fluid is disturbed by means of supporting the propeller.

Alternatively, the technique of rotating the blade by applying a working fluid in a tangential direction to the circumference of the propeller rotating surface is also used, but in this case, the rotation of the propeller may be disturbed due to the resistance caused by the supplied fluid. A very accurate design for the inlet and outlet is required, and there is a problem in that rotation efficiency is low because inflow and outflow of fluid are not performed quickly.

The present invention was devised in consideration of the above points, and the structure for guiding the vanes and improving the structure by which the fluid moves by the movement of the vanes to improve the rotational efficiency of the vanes and rotors with improved rotation efficiency is improved. The aim is to provide a turbine with an assembly.

In order to achieve the above object, the present invention is a body having a fluid inlet hole for the inlet and outlet of the working fluid; A rotor disposed in the interior space of the body and having a plurality of first vane guide grooves radially formed at predetermined intervals along the circumference; A rotating shaft fixed to the center of the rotor; A plurality of vanes that are one-to-one corresponding to the plurality of first vane guide grooves and are slidably fitted to enter and exit the first vane guide grooves; And a cover having a circular second vane guide groove which is formed on an inner surface and an axial hole through which the rotating shaft is fitted and guides the vane, and includes, wherein the axial hole is the second vane guide It is formed at a position off the center of the groove, and when the working fluid is supplied through the fluid entry hole, the rotor rotates and the plurality of vanes slide forward and backward along the first vane guide groove, respectively. It provides a turbine characterized in that it repeatedly protrudes outward on the outer peripheral surface of the.

A vane arm fitted to the second vane guide groove may be provided at least at one end in the vertical direction of the vane.

In the rotor, a guide hole into which the vane arm can be fitted is formed radially, and the vane arm is fitted into the guide hole to prevent the vane from leaving the rotor.

It is preferable that a fluid receiving space adjacent to the vane and in communication with the first vane guide groove is provided in the rotor in the state where the vanes are assembled.

The fluid inlet hole is an arc of a predetermined length in a circumferential direction on one side of the body.

It is preferably a long hole formed in the form.

It may further include; an air vent hole formed on the other side of the body.

The turbine with the vane and rotor assembly according to the present invention has the following effects.

First, since the fluid pressure balance is adjusted by the interaction of the vane, vane arm, vane guide groove, and fluid receiving space, the number of parts can be reduced because the vane can be easily reciprocated in the rotor without an elastic member such as a spring. .

Second, since the vane is constrained within the rotor and does not deviate from the outside of the rotor, stable rotation can be achieved even at high speed.

Third, when the fluid pressure is generated, leakage of the fluid is low even at low speed and torque fluctuation is small in relation to the pressure generation.

Fourth, since it can be manufactured in a compact size, it has low production cost and is convenient to carry and move.

1 to 3, the turbine according to a preferred embodiment of the present invention is a ring body (1), a rotor (5) disposed inside the body (1) and the rotating shaft (4) fixed to the center, It includes a plurality of vanes 8 radially assembled at predetermined intervals along the circumference of the rotor 5 and a lid 3 for capping the upper and lower openings of the body 1.

The body 1 is composed of a ring-shaped frame in which a fluid inlet hole 2 for inflow and outflow of a working fluid is formed on one side. The fluid inlet hole 2 is made of an elongated hole formed in an arc shape by a predetermined length in a circumferential direction on one side of the body 1. The shape, number, and location of the fluid entry and exit holes 2 are not limited to those shown in the drawings, and can be variously modified. In addition, the fluid inlet hole 2 may be configured as a separation type in which a portion into which the working fluid flows is formed on one side of the body 1 and a portion on which the discharged fluid is formed on the other side of the body 1.

When the fluid is a gas, the other side of the body 1, preferably the other side of the fluid inlet hole 2 with reference to the center of the body 1, is discharged by discharging to the outside of the body 1 in advance before discharging the gas An air vent hole 11 for adjusting pressure may be formed. Here, the shape, number, and location of the air vent hole 11 are not limited to those shown in the drawings and can be variously modified.

The rotor 5 is rotatably arranged in the inner space of the body 1. The rotor 5 is arranged such that its center is eccentric to one side with respect to the center of the body 1. Therefore, as shown in FIG. 4, one side of the rotor 5 (A, hereinafter referred to as a'contact portion') is disposed substantially in contact or adjacent to one inner wall of the body 1, the other of the rotor 5 The side (B) is spaced from the inner wall of the body (1) to form a space to be filled with fluid.

The rotating shaft 4 is fixed to the center of the rotor 5 and penetrates the cover 3 coupled to the body 1 and is exposed to the outside.

A plurality of first vane guide grooves 6 are formed at a predetermined interval along the circumference of the rotor 5. Each first vane guide groove (6) is fitted with a vane (8) and arranged radially. The first vane guide groove 6 is formed to a size capable of guiding the vane 8 sliding forward and backward in the radial direction of the rotor 5.

The plurality of vanes 8 correspond one to one to the plurality of first vane guide grooves 6 formed in the rotor 5 and are fitted into the first vane guide grooves 6 so that they can slide forward and backward to the rotor 5 Is assembled. The vane 8 is formed in a substantially flat shape, and both ends of the width direction are formed to be round. At the upper and lower ends of the vane 8, a vane arm 9 having a cylindrical (or elliptical column) shape that can be fitted to the second vane guide groove 10 is protruded. The vane 8 slides forward and backward along the first vane guide groove 6 and repeatedly protrudes outward from the outer circumferential surface of the rotor 5, thereby substantially acting as a piston.

As shown in FIG. 4, the rotor 5 is provided with a fluid receiving space 6a adjacent to the vane 8 in a state where the vane 8 is assembled and at the same time communicating with the first vane guide groove 6. When the rotor 5 is set to rotate clockwise, the fluid receiving space 6a is preferably located on the right side of the vane 8. That is, from the viewpoint of looking down the rotor 5 in FIG. 4, a plurality of vanes 8 are respectively assembled in the first vane guide groove 6, and the fluid receiving space is located on the right side of each vane 8 ( 6a) exists. The fluid receiving space 6a is filled with fluid during operation of the turbine. When the rotor 5 rotates clockwise, the fluid remaining in the fluid receiving space 6a enters the contact portion A before the vane 8 and is compressed, and after passing through the contact portion A, the pressure again decreases. It serves to balance pressure. By this pressure balance adjustment action, the vane 8 can smoothly slide forward and backward in the first vane guide groove 6 to perform piston movement.

The cover 3 is configured in a disc shape to cap the upper and lower opening portions of the body 1. On the cover 3, an axis hole 3a into which the rotation shaft 4 is fitted is formed eccentrically. The shaft hole 3a is formed at a position off the center of the second vane guide groove 10. As illustrated in FIG. 5, a circular second vane guide groove 10 is formed on the inner surface of the cover 3 to guide the movement of the vane 8. The vane arm 9 is inserted into the second vane guide groove 10 so that the vane arm 9 moves along the second vane guide groove 10 when the vane 8 is moved. That is, the second vane guide groove 10 serves to guide the movement of the vane arm 9. It is preferable that a step is formed around the second vane guide groove 10 to guide the peripheral portion of the vane arm 9.

In the rotor 5, a guide elongated hole 7 through which a vane arm 9 is fitted is formed radially. The vane arm 9 is constrained by the guide hole 7 formed in the rotor 5 to prevent the vane 8 from leaving the rotor 5. The guide hole 7 is formed radially on the upper and lower plane portions of the rotor 5 and communicates with the first vane guide groove 6.

When the working fluid is supplied through the fluid inlet hole 2, while the rotor 5 rotates, the plurality of vanes 8 slide forward and backward with respect to the first vane guide groove 6, so that the vanes 8 are repeated. By protruding outward from the outer circumferential surface of the rotor 5, the piston moves to interact with the working fluid.

In addition, when the rotor 5 is rotated, the vane arm 9 provided on the upper and lower ends of the vane 8 is inserted into the second vane guide groove 10 provided in the cover 3, and thus the second vane guide groove 10 Let's go along the circular path. That is, by maintaining the contact of the vane arm 9 with the second vane guide groove 10, the movement of the vane 8 rotating together with the rotor 5 is guided. When the vane (8) slides forward and protrudes outside the outer circumferential surface of the rotor (5), the vane arm (9) is constrained by the guide hole (7) to prevent the vane (8) from escaping out of the rotor (5). do.

Additionally, a separate guide ring is additionally installed on the inner wall of the body 1 and the end of the vane 8 can be rotated in close contact with the guide ring.
