Problems solved by technology

[0005] 2. The swing of the connecting rod in the crankshaft-connecting rod mechanism causes the gas pressure acting on the piston to generate a lateral pressure acting vertically on the cylinder wall, which increases the lateral friction between the piston and the cylinder wall and accelerates the wear of the cylinder wall , which not only reduces the working efficiency of the piston, but also causes the "cylinder" to make the piston unable to work
[0006] 3. Since the top and bottom dead centers of the crankshaft correspond to the top and bottom dead centers of the piston, and the rotation diameter of the crankshaft is equal to the stroke of the piston, it is necessary to install an energy storage flywheel so that the crankshaft crosses the top dead center and then ignites. The gas compression ratio in the cylinder is not at the maximum state at the moment of ignition. , reduce the gas explosion expansion pressure at the moment of ignition, and at the same time increase the resistance of starting and shifting due to the existence of the flywheel

Abstract

The invention provides a gear-tooth block meshing switching device for linear reciprocating motion and rotational motion. Four pairs of track plates are mounted in a casing, one ends of the track plates are hinged to the inner walls of the two sides of the casing, the other ends of the track plates are provided with track grooves respectively, and a track shifting mechanism lifter is arranged among the four pairs of track plates. Tooth block lines including a plurality of tooth blocks are mounted on a driving frame mechanism, sliding pins extending from two sides of each tooth block are respective disposed in each track groove, a gear fixedly mounted with a transmission shaft is arranged between the two tooth block lines, and the lifter driving device drives the lifter to lift or descend the track plates. Besides, a frame of the driving frame mechanism is connected with one end of a connecting rod, and the other end of the connecting rod is connected with a piston. The switching device is capable of realizing equivalent switching between linear reciprocating motion and rotational motion.

Description

technical field [0001] The invention relates to a reciprocating linear motion and rotary motion conversion device, in particular to a gear-rack meshing motion conversion device for mutual conversion between linear reciprocating motion and circular motion. Background technique [0002] In mechanical engineering, such as piston engines, compressors and other machines that need to convert between linear reciprocating motion and circular motion, the crankshaft (crank) connecting rod mechanism is generally used at present. [0003] The design and manufacture of the traditional crankshaft (handle) linkage mechanism has been very perfect, but there are obvious shortcomings in both theoretical analysis and practical application: [0004] 1. The conversion efficiency of the crankshaft (handle) linkage mechanism is low. Taking the piston-connecting rod-crankshaft (handle) mechanism engine as an example, the gas explosion pressure of the piston is transmitted to the crankshaft (handle...
