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
Affiliated technical field
The present invention relates to a kind of annular tesla turbine, belong to the steam turbine technology field.
Background technique
Tesla's turbine claims not have the leaf turbine again, and its shape is to be fixed with a plurality of smooth and thin disks by a determining deviation on the axle, and air-flow impacts these disks from tangent direction, utilizes effect of boundary layer to drive these disks and rotates together with axle.Though that this turbine has is simple in structure, volume compact, low cost and other advantages because disk size when big rigidity yielding inadequately, eddy current is scratched greatly between dish, vibrates shortcoming such as big and fails popularization and application.
Summary of the invention
For overcoming the deficiency of existing technology, the present invention provides a kind of annular tesla turbine, and this annular tesla turbine rotor is a ring; Stator places internal rotor, and stator one end diameter is big, and an end diameter is little; On the big end of stator nozzle is arranged, the bigger formation relief opening of small end and rotor clearance, the rotor inboard is covered with annular flake; Annular flake spacing near nozzle is little, and is big near the annular flake spacing of relief opening, nozzle along rotor annulus tangent direction to rotary jet; Air-flow can form eddy current under the leading role of rotor annulus inboard, owing to be covered with the surface of contact that the inboard annular flake of annulus has increased rotor annulus and air-flow greatly, and according to effect of boundary layer; The rotor annulus will be driven rotation together by air-flow, thereby realize the rotation of rotor.This annular tesla turbine replaces the thin disk of traditional tesla turbine with the inboard annular flake of rotor annulus; Annular flake can be made of one with annulus or support and fixing from encircling; So than thin disk good rigidity, not yielding, make rotor can do to such an extent that diameter is yielding more greatly and not.The form of annular flake can have two kinds, a kind of be ring with ring between be parallel to each other and do not link to each other mutually, another kind be ring and encircle between the formation internal screw thread form that joins end to end.
The invention has the beneficial effects as follows, the size of tesla's turbine is done greatly, thereby power strengthens, efficiengy-increasing and operation are more steadily reliable.

Embodiment
In Fig. 1, stator (1) places rotor (2) inside, and the big end of stator (1) has nozzle (3); Nozzle (3) can have a plurality of, should evenly distribute, so that ejection lets during air-flow rotor (2) stressed evenly; Cross-section structure of the present invention is as shown in Figure 2; Be followed successively by rotatingshaft (4) from top to bottom, rotor loam cake (5), rotor (2).Stator (1) places rotor (2) inside, and stator (1) one end diameter is big, and an end diameter is little; On the big end of stator (1) nozzle (3) is arranged; The bigger formation relief opening in small end and rotor (2) gap (7), rotor (2) inboard is covered with annular flake (6), and is little near the annular flake spacing of nozzle (3); Annular flake spacing near relief opening (7) is big.
Gas leads to nozzle (3) by tracheae (8) during work; Spray to rotor (2) inboard by nozzle (3), air-flow can form eddy current under the leading role of rotor (2) inboard, has increased the surface of contact of rotor (2) with air-flow greatly owing to be covered with the inboard annular flake (6) of rotor (2); According to effect of boundary layer; Rotor (2) will be driven rotation together by air-flow, thereby realize the rotation of rotor (2), finish the general gas of merit and discharged by relief opening (8).
Claims (1)
1. an annular tesla turbine comprises rotor, stator and nozzle, it is characterized in that: rotor is a ring; Stator places internal rotor, and stator one end diameter is big, and an end diameter is little; On the big end of stator nozzle is arranged, the bigger formation relief opening of small end and rotor clearance, the rotor inboard is covered with annular flake; Annular flake spacing near nozzle is little, and is big near the annular flake spacing of relief opening.
