Mechanism substituting cylinder crankshaft system with to-and-fro rectilinear motion mode

Abstract

The present invention relates to a kind of transmission mechanism of cylinder (comprising internal combustion engine and compressor) piston, especially to the improvement of existing crankshaft transmission mechanism, it comprises piston push rod, support base supporting piston push rod, large flywheel and eccentric shaft, piston One end of the push rod is connected with the piston of the cylinder, and the power output shaft is fixed on the large flywheel, which is connected to the running machine. The shaft overlaps with the center of the large flywheel. The body of the large flywheel is inlaid with an eccentric groove shaft smaller than the large flywheel. One side of the large flywheel is matched with the piston push rod, and the other side is fixed with a power output shaft; more than 2 are set on the piston push rod Or a plurality of zero-gram shafts that promote zero angles. On the large flywheel, two or more arc-shaped zero-gram pieces are fixed on both sides of the grooved shaft.

Description

technical field [0001] The invention relates to a transmission mechanism of a piston of a cylinder (including an internal combustion engine and a compressor), especially an improvement to the existing crankshaft transmission mechanism. Background technique [0002] Designers of internal combustion engines know that the power of the internal combustion engine has a lot to do with the transmission device. The power output of the internal combustion engine seen at present is to drive the crankshaft connecting rod mechanism through the reciprocating motion of the piston to do work and drive the machine to run. The power output of the internal combustion engine is related to the crankshaft thrust angle. The larger the thrust angle, the higher the output power, and the smaller the thrust angle, the smaller the output power. Generally, the maximum thrust angle of the crankshaft can only reach 45 degrees, so the traditional crankshaft has many disadvantages as follows: 1. When the a...

The power output of the internal combustion engine is related to the crankshaft thrust angle. The larger the thrust angle, the higher the output power, and the smaller the thrust angle, the smaller the output power. Generally, the maximum thrust angle of the crankshaft can only reach 45 degrees, so the traditional crankshaft has many disadvantages as follows: 1. When the arm is at the upper and lower dead points, the connecting rod reciprocates as a guiding motion, which will cause strong vibration and shorten the life of the machine; 2. When the crankshaft swings, the strong friction between the piston and the cylinder will increase the temperature of the lubricating oil, and the cylinder will easily lose its roundness; 3. When the crankshaft rotates, if the arc of the swing is too large, the parallel performance will be worse, the horsepower will decrease accordingly, and the vibration will be correspondingly strong, resulting in shortened machine life; 4. The arc of the crankshaft swing is too small, the piston stroke will be shortened, and the horsepower will also change accordingly Small, at this time, the combustion rate of the internal combustion engine is poor, the fuel consumption increases, and the pollutants discharged also increase

[0008] Known from the above-mentioned published patents, in order to overcome the power consumption caused by the crankshaft motion of the existing internal combustion engine, people have designed racks, gears, output power to the straight main shaft through the power transmission chain, or improved the structure of the internal combustion engine, but these There are still some shortcomings in the design: 1. The rack and gear lose useless work; 2. The rack and gear cannot run at high speed; 3. When the rack and gear are worn for a long time, the output shaft will be displaced. , affect the work of the machine, and even produce problems such as loud noise

However, this patent disclosed by the inventor still has the following problems: 1. The diameter of the small flywheel is small, and when the large flywheel is driven to rotate, the force is large, and the small flywheel is easily damaged. 2. When the axis of the large flywheel coincides with the center of the piston push rod When moving, it cannot rotate and can only rely on inertial motion, so the work cannot be continuous, that is to say, the piston push rod in linear motion becomes the zero angle when it moves in a circle (the upper dead point, the lower dead point, and the middle dead point coincide. Circumstances) exist, so that its work disappears at zero angle; 3. When the original start needs to be manually or mechanically moved the large flywheel to proceed, it is troublesome to operate
