JP6537001B1 - Lubrication system for reciprocating part of vane for vane engine. - Google Patents

Abstract

A method of lubricating a reciprocating portion of a vane so that solid contact does not occur in a slit of a rotor. SOLUTION: A liquid containing a sinter-resistant heat-resistant powder such as silicon carbide or silicon nitride is applied to the rear end of the vane reciprocating part and the inlet of the slit accommodating the vane reciprocating part, and they are fitted together and re-sintered When the opposing wall surfaces approach, the gas pressure between them increases, and when the wall surfaces separate, the gas pressure between them decreases. When an external force is applied to the wall, the wall moves and balances. As a result, the reciprocating portion of the vane floats in the slit and can be lubricated and sealed with high pressure gas to prevent individual contact. 【Selection chart】 None

  Without the use of lubricating oil, the reciprocating part of the vane must be in solid contact in the slit of the rotor containing it.

  A porous cover is provided at the rear end of the reciprocating portion of the vane, and a porous mouth ring is also provided at the outlet of the slit portion of the rotor that accommodates the vane reciprocating portion. Apply a liquid containing sintered heat-resistant powder such as silicon carbide and silicon nitride to the rear end of the vane reciprocating part and the porous cover, and apply silicon carbide and silicon nitride to the slit outlet and the porous die. Apply a liquid containing a sinterable heat-resistant powder, fit in each other, re-sinter it and integrate it.

  The width and thickness of the reciprocating part of the vane and the slit have a difference of several tens to several hundreds of μm, and by injecting high pressure gas from the porous part, the opposing wall surfaces approach and the gas pressure in between increases and the wall surface As it leaves, the gas pressure in between falls. The opposite side of the wall is the same, and the wall becomes stable when the gas pressure in the vicinity of both walls is balanced. When an external force is applied to the wall, the wall moves and balances. This causes the reciprocating portion of the vane to float in the slit. This is the lubrication and seal of the reciprocating part of the vane.

  It is possible to avoid the solid contact of the vane reciprocating part with the vane tip of the vane engine and to fully exhibit the function of the vane engine.

  High pressure gas supply holes are used when producing rotors and vanes with carbon fiber, vinyl chloride resin and other destructible structural materials, silicon carbide and silicon nitride sinterable heat resistant particles, silicon carbide and silicon nitride such as sinterable heat resistant powder, etc. And burnout of vinyl chloride resin and other burnable structural materials. Also, lubrication of the rotor bearings, seals between the rotor and the side case, etc. are all performed with high pressure gas.

  There is no example.

  Although the conventional engine is a heat engine, in order to eliminate the contradiction to cool, a lubricating seal with high pressure gas is used to increase the rate of converting heat to effective energy. Also, referring to the Carnot cycle, increase the heat supply (combustion) temperature as much as possible, increase the expansion coefficient to make the exhaust temperature as low as possible, and make steam from the exhaust heat and press it into the working chamber Enables thermal efficiency of around 60%, and enables halving, lightweight and compact of harmless exhaust and global warming gas. This allows the heat engine to see technological developments from steam engines to gasoline diesel engines and from gasoline diesel engines to vane engines.
