Embodiment Construction

[0042] The present invention will now be further described in detail in conjunction with the accompanying drawings, which are simplified schematic diagrams, only schematically illustrating the basic structure and working methods of the present invention, so they only show the configurations related to the present invention.

[0043] Such as figure 2 As shown, the end surface lubrication and sealing structure of the rotor engine disclosed in this embodiment includes the end surface texture structure 2 on the end surface of the rotor main body 1 and the magnetic fluid lubricant 3 . It is characterized in that: when the rotor main body 1 rotates at high speed in the engine cylinder, the end face texture structure 2 can store a small amount of lubricating oil, thereby forming a lubricating oil film between the end face of the rotor and the end face of the cylinder head, improving the lubrication and sealing performance between the two; The end surface texture structure 2 is unifo...

Abstract

The invention discloses an end face lubricating and sealing structure of a rotor engine, and belongs to the technical field of small rotor engines. The end face lubricating and sealing structure comprises an end face texture structure located on the end face of a rotor body and a magnetofluid lubricant. The magnetofluid lubricant is mainly composed of a base solution, magnetic solid particles and a surfactant. The end face texture structure is a micro-modeling bionic diatom texture with a three-level hole shape, and magnetic surface textures which are evenly arranged and used for forming magnetic force with the magnetofluid lubricant are arranged in the end face texture structure. The end face texture structure is filled with the magnetofluid lubricant. By means of the end face lubricating and sealing structure, good lubricating and sealing performance of the end face of the small rotor engine can be guaranteed, wear of the rotor end face and the cylinder cover end face is reduced, and then the service life of the small rotor engine is prolonged; and in addition, the viscosity of the magnetofluid lubricant is controlled by adjusting an external magnetic field, and therefore the dynamic pressure characteristic of a lubricating film is changed, and the bearing performance and sealing and lubricating performance of the rotor end face and the cylinder cover end face are adjusted.

Description

technical field [0001] The invention relates to an end face lubricating and sealing structure of a small and medium-sized rotor engine, and belongs to the technical field of small-sized rotor engines. Background technique [0002] In the miniaturized electromechanical industry, such as small car range extenders, small unmanned aerial vehicles, military individual combat systems, small robots, etc., batteries are currently the main source of power for these devices. Due to the disadvantages of low energy density and short service life of the battery, it is gradually unable to meet the demand. Even the current relatively advanced lithium-ion battery has an energy density far lower than that of the internal combustion engine, which is only about 1 / 20 of the internal combustion engine. Therefore, how to provide small power devices with high energy density, high reliability and long life for these small devices has become an increasingly prominent problem. [0003] The developme...
