Rotor mechanism and rotary vane engine

Abstract

The invention discloses a rotor mechanism and a rotary vane engine. The rotary vane engine comprises a machine shell assembly, a rotating shaft part and the rotor mechanism, the rotor mechanism comprises a rotor seat and at least one set of vane group, a first channel is arranged on the rotor seat, each set of vane group comprises a first vane and a second vane which are rotatably connected to the rotor seat, the machine shell assembly is provided with a machine shell inner cavity, a first input channel and a first output channel, the rotor mechanism is located in the machine shell inner cavity and connected with the rotating shaft part, the first vane and the second vane can rotate to abut against the wall face of the machine shell inner cavity under the action of fluid pressure in the first channel so that a combustion cavity can be separated in the machine shell inner cavity, the combustion cavity can drive the rotor mechanism to rotate through combustion expansion of fuel so as to have different states, and the first input channel and the first output channel can communicate with the combustion cavities in the different states correspondingly. According to the rotor mechanism and the rotary vane engine, by means of the pressure of fluid, abutting of the vanes can be stable and reliable, and the use reliability is improved.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a rotor mechanism and a vane engine.

[0002] Among the existing engines, the engines with relatively mature technology are mainly reciprocating piston engines and rotary engines. For rotary engines, the abutment between the blades on the rotor and the inner wall of the casing is generally through the blades themselves. The rotational inertia of the leaf itself or the elastic force of the spring is used to abut against the inner wall of the casing through the rotational inertia of the leaf itself, the effectiveness of the abutment is poor, and abutment failure is prone to occur. Affect the sealing of the chamber separated by the leaf; for the method of abutting the leaf and the inner cavity wall of the casing through the elastic force of the spring, due to the spring has a certain service life, it may occur after a long period of use. Elastic failure will affect the service life of the engine. At the same time, it is easy to cause a gap between the blade and the inner wall of the casing, which will affect the sealing of the chamber separated by the blade. Regular maintenance is required, and the setting of the elastic member will cause the rotor mechanism to The connection structure is more complicated, the assembly and disassembly are more troublesome, and it is not easy to use
