Method for eliminating torsion inertia force of double-rotor piston engine

Abstract

The invention discloses a method for eliminating the torsion inertia force of a double-rotor piston engine. The double-rotor piston engine comprises two sets of power units each of which consists of a power cylinder assembly and a differential driving assembly connected with the power cylinder assembly; and a reverse synchronization assembly for offsetting the torsion inertia force produced when parts in the power units do non-uniform rotation is arranged between the two sets of the power units. The double-rotor piston engine designed by the method has no torsion inertia force and has the advantages of various power output modes, reliability and high adaptability, and transmits stably.

Description

technical field [0001] The invention mainly relates to the design field of a double-rotor piston engine, in particular to a method for eliminating torsional inertia force. Background technique [0002] Piston engines mainly include reciprocating piston engines and rotary piston engines. A crank linkage is used for power transmission on most reciprocating piston engines. For more than 100 years, researchers have carried out extensive research on the crank connecting rod mechanism, and at the same time, they are committed to reducing the inertial load and side pressure, overcoming the dead point of motion, and improving the transmission efficiency of the engine by adding some auxiliary mechanisms. Although these studies have improved the power performance of the reciprocating piston engine to a certain extent, they have not fundamentally changed the status quo of the low power density of the engine due to the inherent defects of the power transmission part. The rotary piston...

AI Technical Summary

Problems solved by technology

The power density of this engine is relatively high, and the application prospect is promising. However, due to the complex shape of the rotor, the manufacturing cost is high, and there are difficult problems such as sealing difficulties, poor power performance at low speeds, and poor fuel economy. The superiority has not been fully utilized so far

[0003] The lower power density not only restricts the further improvement of the performance of the piston engine, but also limits the application of the piston engine in many occasions

The above two types of piston engines are limited by the inherent defects of the power transmission part, and the power density is difficult to reach 1 (Kw / Kg)

The low power density of power sources has become a bottleneck in the development of some equipment technologies

[0004] In order to improve the characteristics of traditional piston engines, various solutions have been proposed, among which the dual-rotor piston engine is a very popular research direction. Over the years, a large number of researches have been carried out at home and abroad. Breakthroughs have been made in the power transmission structure and transmission method, but the existing research on dual-rotor piston engines has not considered the problem of eliminating the torsional inertia force caused by the non-uniform rotation of the rotors.
