Embodiment Construction

[0008] exist figure 1 Among them, the stator (1) is placed inside the rotor (2), and the big end of the stator (1) is provided with nozzles (3). There can be multiple nozzles (3), which should be evenly distributed so that the rotor (2) Evenly stressed, the cross-sectional structure of the present invention is as figure 2 As shown, from top to bottom are rotating shaft (4), rotor upper cover (5), and rotor (2). The stator (1) is placed inside the rotor (2). One end of the stator (1) has a large diameter and the other end has a small diameter. There is a nozzle (3) on the large end of the stator (1), and a large gap between the small end and the rotor (2) forms an exhaust gas. The mouth (7), the inner side of the rotor (2) is covered with annular thin slices (6), the annular thin slices near the nozzle (3) have a small spacing, and the annular thin slices near the exhaust port (7) have a large spacing.

Abstract

The invention provides an annular Tesla turbine. A rotor of the ring-shaped Tesla turbine is made into a circular ring; a stator is arranged inside the rotor; the stator has bigger diameter at one end and smaller diameter at the other end; the bigger end of the stator is provided with a spray nozzle; the smaller end of the stator and the rotor have a bigger gap to form an exhaust port; annular thin sheets are fully distributed at the internal side of the rotor; the annular thin sheets close to the spray nozzle have small gaps and the annular thin sheets close to the exhaust port have big gaps; the spray nozzle injects the air toward the rotor along the tangent line direction of the circular ring; an airflow can form a vortex flow under the guide action of the internal side of the circular ring and drive the circular ring to rotate together, so that the rotation of the rotor is realized. The annular Tesla turbine disclosed by the invention can replace a thin circular tray of the traditional Tesla turbine by using the annular thin sheets at the internal side of the circular ring; the annular thin sheets can be integrated with the circular ring into a whole or are supported and fixed from the ring, the rigidity of the annular thin sheets is better than that of the thin circular tray, and the thin sheets are not easy to deform, so that the diameter of the rotor can be bigger and rotor are not easy to deform, accordingly, the power is increased, the efficiency is improved and the operation process is stable and reliable.

Description

Technical field [0001] The invention relates to an annular Tesla 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. The airflow hits these discs from a tangential direction, and the boundary layer effect drives these discs and the shaft Turn together. Although the turbine has the advantages of simple structure, compact volume, and low cost, it has not been widely used because of the disadvantages of insufficient rigidity and easy deformation when the disk size is large, large eddy current deflection between disks, and large vibration. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a ring-shaped Tesla turbine. The rotor of the ring-shaped Tesla turbine is circular, and the stator is placed inside the rotor. One end o...
