Problems solved by technology

Although the turbine has the advantages of simple structure, compact volume, high efficiency, and low cost, because the viscous force generated by a single smooth disk is very small, in order to increase the torque, the number of disks should be as large as possible, thin, and large in size. In this way, the rigidity is not enough and easy to deform, resulting in large eddy current deflection between disks, large vibration and other shortcomings, so it has not been widely used.

Embodiment Construction

[0010] exist figure 1 with figure 2 Among them, there is a nozzle (3) on the casing (4), and there is a rotor inside the casing (4). The rotor is composed of a disc-shaped blade (2) and a disc-shaped blade (7) fixed on the rotor shaft (6). The air vents (1) are densely covered with the disc-shaped blades, and the center of the disk-shaped blades has an air vent (5), and the vent (5) is directly facing the exhaust port (8) on the housing (4).

[0011] When working, the gas is sprayed into the housing (4) from the nozzle (3), and the air flow will form a vortex between the disc-shaped blades (2) and the disc-shaped blades (7) under the guidance of the inner side of the housing (4), The vortex drives the disk-shaped blade (2) and the disk-shaped blade (7) to rotate together, so as to realize the rotation of the rotor, and the exhaust gas after work is passed from the exhaust hole (5) in the center of the disk-shaped blade to the exhaust port (8) discharge.

Abstract

A penetrating type worm wheel comprises a nozzle, a shell and a disc-shaped blade. Small holes are densely distributed in the whole disc-shaped blade, or the disc-shaped blade is directly made of porous materials, and therefore airflow can freely penetrate through the disc-shaped blade. Therefore, when airflow flushes the disc face or gas pressures on the two sides of the disc-shaped blade are different, penetration can happen, and the viscous force of airflow on the disc face is greatly enhanced. Compared with a smooth disc of a Tesla worm wheel, the number of blades can be small, the thickness can be large, the rigidity of the penetrating type worm wheel is better than that of the thin disc of the Tesla worm wheel, the size of the worm wheel can be large, the worm wheel cannot deform, and therefore power is increased, and running is more stable and reliable.

Description

Technical field [0001] The invention relates to a penetrating turbine, which belongs to the technical field of steam turbines. Background technique [0002] The Tesla turbine, also known as a bladeless turbine, is shaped like a shaft with multiple smooth and thin discs fixed at a certain distance, and the airflow washes these disc-shaped blades from the tangential direction, using the viscous force generated by the boundary layer effect These discs are driven to rotate together with the shaft. Although the turbine has the advantages of simple structure, compact volume, high efficiency, and low cost, because the viscous force generated by a single smooth disk is very small, in order to increase the torque, the number of disks should be as large as possible, thin, and large in size. In this way, the rigidity is not enough and easy to deform, resulting in large eddy current deflection between disks, large vibration and other shortcomings, so it has not been widely used. Cont...
