Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] figure 1 Described is the airtight scribe 1 on the top corner of the triangular rotor 6, the scribe 1 has a slot 3 on it, and an axial spring 4 is installed inside.

[0021] figure 2 It describes the scribe 1 and scribe 2 that are bonded together. The axial spring 4 inside the slot 3 provides the opposite direction axial elastic force for the scribe 1 and the scribe 2, so that the scribe 1 and the scribe 2 are closely connected with each other. The end cap 20 contacts, so that the airtightness between the dicing blade and the engine end cap 20 is good.

[0022] image 3 It is described that the dicing piece 1 and the dicing piece 2 are bonded together, and there is a gap between the bonding surfaces of the two dicing pieces, and lubricating oil can flow through it to provide lubrication for the friction between the dicing p...

Abstract

The invention discloses a heavy oil aviation rotor engine. A scribing piece for axial and radial elastic compensation sealing consists of two scribing pieces bonded together; grooves for placing springs are respectively formed in the two scribing pieces; the two scribing pieces are synchronously supported by the springs inside; and axial elastic force in two directions is provided to the scribing pieces to enable the scribing pieces to axially and tightly bond on an end cover of a rotor engine. Lubricating oil holes are respectively formed in all vertex angles of a triangular rotor; and springs are put in the lubricating oil holes for providing radial elastic force to the two scribing pieces, so that the two scribing pieces can be tightly bonded on the inner surface of a cylinder. The scribing piece for axial and radial elastic compensation sealing is excellent in air tightness of the rotor engine. The lubricating oil holes guide lubricating oil between the bonded surfaces of the two scribing pieces under the effect of centrifugal force; the centrifugal force enables the lubricating oil to permeate out from the bonded surfaces of the two scribing pieces to provide lubrication to the cylinder of the rotor engine and the scribing pieces; and the excellent lubrication can improve the durability of the rotor engine.

Description

technical field [0001] The invention relates to a long-life aviation rotary engine capable of fully burning heavy oil. Background technique [0002] In the current prior art, due to poor air tightness and serious air leakage of some rotary engines, it is difficult to ignite the rotary engines and the working efficiency decreases. Some have poor lubricating effects. During operation, the poor lubrication will cause rapid friction loss on the inner surface of the cylinder and the friction surface of the end cover. Severe friction loss will shorten the service life of the rotary engine and increase the cost of use. For example, the application number of the patent number is CN201621059478.2, the sealing sheet described in the patent of the top sealing and lubricating device of a rotor engine, the outer two are rigid sealing sheets, and the middle is a flexible sealing sheet. Wear, long-term operation will lose the lubricating effect. The application number is CN201520785291.X...
