Problems solved by technology
[0004] In the crank-and-rod mechanism in the prior art, during the power transmission process of the piston, the crankshaft rotation will be affected by the alternating gas pressure, reciprocating inertial force and centrifugal force of each cylinder, as well as the bending moment and torque caused by these forces. Forced torsional vibration occurs, forming complex alternating stress and additional stress of torsional or bending vibration. When the stress concentration is severe and the stress on the crankshaft exceeds its fatigue strength, the crankshaft will break, which will lead to failure of the crank connecting rod mechanism. normal work

The invention discloses a reciprocating-rotating motion conversion mechanism. The mechanism comprises a main rotating shaft module, a synchronous crankshaft, a connecting rod set and a machine body; the main rotating shaft module includes at least one main rotating shaft module unit; the each unit includes at least two reciprocating motion pieces, a planet crankshaft, a left support crankshaft and a right support crankshaft; the left support crankshaft and the right support crankshaft are respectively arranged at the left and right two ends of the planet crankshaft; a left support neck of the planet crankshaft is matched and connected with a terminal crank pin at the right end of the left support crankshaft; a right support neck is matched and connected with a terminal crank pin at the left end of the right support crankshaft; a rotating shaft of the synchronous crankshaft is parallel to the main rotating shaft; and a connecting rod of the connecting rod set is connected with a synchronous crankshaft crank pin of the synchronous crankshaft and a connecting rod crank pin of the left support crankshaft or the right support crankshaft in the corresponding position or the support neck of the planet crankshaft. The reciprocating-rotating motion conversion mechanism realizes rotary output or rotary input through an output shaft or an input shaft arranged on the synchronous crankshaft.
Description
[0001] This application claims the priority of the Chinese invention patent application with the application date of December 30, 2015, the Chinese patent application number 201511031170.7, and the title of "a reciprocating-rotary motion conversion mechanism". technical field [0002] This application relates to the mechanical field, specifically a reciprocating-rotating motion conversion mechanism. The present application also provides an internal combustion engine, a compressor and a water pump using the above-mentioned reciprocating-rotating motion conversion mechanism. Background technique [0003] In a traditional internal combustion engine, the reciprocating motion of the piston is usually converted into the rotational motion of the crankshaft through a crank-link mechanism, and then the crankshaft drives the corresponding moving parts to output power externally. In a traditional compressor, the rotary motion of the crankshaft is converted into the reciprocating motion...
