Abstract
The utility model discloses a pneumatic screw engine, which comprises a machine base, a machine cover, a closed cover, a bearing and a through cover, wherein an inlet is formed on the machine cover; an outlet is formed on the machine base; the machine base and the machine cover enclose to form a cavity through the closed cover and the through cove; a main shaft is arranged in the cavity of the machine base and the machine cover; one end of the main shaft passes through the through cover and is arranged outside the machine base cavity; one or more helical wheels are fixed on the main shaft in the machine base cavity; one or more helical worm wheels can be also fixed on the main shaft; and one or more combinations of the helical wheels and the helical worm wheels can be also fixed on the main shaft. In the pneumatic screw engine, the steam or hot air of industrial after heat serves as a power source to drive the helical wheels and the helical worm wheels to drive the main shaft to work. Due to the adoption of a single shaft structure, compared with the prior art, the pneumatic screw engine has the following advantages of high speed, light load, no exhaust pulse phenomenon of helical rotation, low pneumatic noise, low vibration, good working environment, high volumetric efficiency and long service life.
Description
Technical field
The utility model relates to a kind of pneumatic helical engine.
Background technique
In existing device for generating power by waste heat, adopt twin-screw power engine, i.e. biaxial system mostly.The radial load of double-screw compressor gas is big, so the main frame bearing life of double-screw compressor is shorter, can only work under low exhaust pressure, and the axle bending deflection easily of twin-screw, cause the back lash big, leak also greatlyyer, added clearance volume, so volumetric efficiency is low slightly.It is bigger to impact the gearing noise and the vibration that are produced in addition between the twin-screw flank of tooth mutually.There is engagement pair in its transmission of twin-screw power engine, the requirement on machining accuracy height, and Equipment Requirement height, meshing wear are also inevitable, and the life-span is restricted, and maintenance and operating cost are higher.
The model utility content
The purpose of this utility model just provides that a kind of simple in structure, long service life, operation expense are low, the pneumatic helical engine of high working efficiency.
Pneumatic helical engine of the present utility model, comprise support, cover, stifle, bearing, Tong Gai, have import on the cover, outlet is located on the support, support and cover surround cavity by stifle, Tong Gai, main shaft is by in the cavity of Bearing Installation between support and cover, one end of main shaft passes logical lid and is located at outside the support cavity, be fixed with one or more helical wheel on the main shaft in the support cavity, also can be fixed with one or more helical turbine on the main shaft, also can be fixed with the combination of one or more helical wheel and helical turbine on the main shaft.
Pneumatic helical engine of the present utility model is to utilize the steam of industrial exhaust heat or hot gas to be power source, and drive helical wheel, helical turbine do work motion of main shaft, because it adopts single-shaft configuration, compared with prior art have the following advantages:
1, high speed light loading, the no exhaust pulsation phenomenon of spiral rotation, pneumatic noise is little, vibrate for a short time, and working environment is better, and does not have the gearing noise that mutual impact is produced between the twin-screw flank of tooth;
2, when work, screw axis can bending deflection, does not have engagement, leaks for a short time, and adding does not have clearance volume, so the volumetric efficiency height;
3, spiral symmetry on the screw axis circumference, gas (vapour) the body radial force that acts on the spiral is cancelled out each other, so the bearing of spiral be not subjected to any axially and the effect of radial force, the bearing life of spiral is prolonged.
