Vane type engine

Abstract

The invention relates to a vane type engine which comprises a cylinder, wherein the cylinder is provided with an air inlet, an exhaust port and a power output shaft; the power output shaft is a sectional shaft with different shaft diameters; the upper and lower ends of the shaft are respectively an upper thin shaft and a lower thin shaft, and the middle section is a large shaft which is in an external gear structure; the power output shaft is provided with an upper vane shaft and a lower vane shaft which are sleeved on the power output shaft in an opposite intersected mode and are both provided with vanes; the upper cylinder wall and lower cylinder wall of the cylinder are respectively provided with an upper base shaft and a lower base shaft; the upper and lower thin shafts of the power output shaft respectively pass through the upper and lower base shafts; the upper and lower base shafts are respectively in an external gear structure and are respectively sleeved on two ends of the shaft holes of the upper and lower vane shafts; and the upper and lower vane shaft holes are respectively provided with inner teeth adaptive to the upper and lower base shafts and the larger shaft. The engine is simple and reasonable in structure and stable in operation, can output larger torsion through the power output shaft, and is economic and practical.

Description

technical field [0001] The invention relates to an engine, in particular to a vane type rotary engine which converts heat energy into mechanical energy by burning gas in a cylinder. Background technique [0002] At present, piston engines and rotary engines are most used in the market, among which piston engines use the periodic changes in the volume of compressed gas in the cylinder to push the piston to reciprocate in the cylinder to complete the four stages of air intake, compression, work, and exhaust. The shortcomings of this working process are mainly in the following aspects: the vibration is too large during operation, and the up and down movement of the piston when the piston engine is running will cause a large vibration of the body, which has high requirements for installation; the noise is too large during operation. , The torque is small during operation, and they have to be lined up to increase the torque, which requires consideration of the pace of each single...

[0002] At present, piston engines and rotary engines are most used in the market. Piston engines use the periodic changes in the volume of compressed gas in the cylinder to push the piston in the cylinder. The reciprocating motion completes the four working processes of air intake, compression, work, and exhaust. The shortcomings are mainly in the following aspects: the vibration is too large during operation, and the up and down movement of the piston when the piston engine is running will cause the body to move greatly. There are high requirements for installation; the noise is too loud during operation, and the torque is small during operation, so they have to be arranged in order to increase the torque, which requires consideration of the pace of each single engine; Rods and other complex designs reduce the reliability of the machine

The deficiencies of the rotary engine include: the high fuel consumption of the rotary engine, which is mainly because the shape of the combustion chamber of the rotary engine is not conducive to complete combustion, and the flame propagation path is long, which increases the consumption of fuel and engine oil; the output power is large, But the torque is low; the route of the rotor moving in the cylinder is in the shape of 8, and the movement is more complicated
