Problems solved by technology
But at the same time, the rotor machine itself also has weaknesses, and the air leakage problem caused by sealing has always been a difficult point that people want to overcome.
Long-term operation will inevitably cause front and rear partial wear of the sealing plate, which may cause the sealing plate to leave the cylinder surface and cause air leakage
The above factors all belong to poor sealing performance, which in turn affects the dynamic performance of the power unit

Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.
[0026] Combined with the schematic diagrams, the processing is carried out under the premise of ensuring accuracy, and the size is set according to the specific power device.
[0027] The position of the new seal on the rotor is as follows: figure 1 As shown, the black dot represents the sealing part 1 at the top. Because it is a triangular rotor machine, there are three top radial seals. The end face sealing of the triangular rotor machine is completed by the sealing column and the end face sealing strip. The arrangement is as follows: figure 1 shown.
[0028] This article only discusses the sealing part 1 at the top, so the end face sealing strip 7 is not discussed. The clear structure at the top is as follows figure 2 shown. See the specific structure image 3...

The invention belongs to the field of mechanical seals, and is a novel seal at the top of a rotor based on a piston rotor engine. The cooperation between the needle roller seal and the two sections of sealing columns in the present invention is connected by the assembly method of the rolling body and the outer ring in the needle roller bearing, including the needle roller seal, the sealing column, the wave spring sheet; the needle roller Type seals, seal columns, and wave springs are assembled sequentially from top to bottom; there is an arc-shaped groove on the seal column along the axial direction, and the needle-type seal is placed in the arc-shaped groove; A wave spring piece, the wave spring piece is placed in the arc groove of the rotor. Among them, the needle roller seal uses its rolling seal with the inner wall of the cylinder to replace the original seal with the sliding seal with the inner wall of the cylinder, which ensures the sealing, stability and power.
Description
technical field [0001] The invention belongs to the field of mechanical seals, and is a novel seal at the top of a rotor based on a piston rotor engine. Background technique [0002] Due to its special structure and motion mode, the rotary engine has the advantages of simple structure, few parts, small size, light weight, high power-to-weight ratio, stable operation, and low production and maintenance costs, etc. that cannot be compared with reciprocating machines. Since its inception, it has attracted great attention and has become a research hotspot in the field of power machinery, and has been widely used in power devices such as automobiles, drones, missiles, small motors, and logging machinery. But at the same time, the rotor machine itself also has weaknesses, and the air leakage problem caused by sealing has always been a difficult point that people want to overcome. [0003] During the movement, the top of the rotor contacts and seals with the inner wall of the cyli...
