Reciprocating-rotating power converting mechanism without crank, and its engine and compressor

Abstract

The present invention discloses a reciprocating-rotating power converting mechanism without crankshaft, and its engine and compressor, wherein the power changeover mechanism consists of the alligatoring ring frame 1, the power wheel 2 and the planet wheel 3 connected with the reciprocating power unit replaces the conventional crankshaft connecting rod system; the planet wheel 3 adopting the power wheel 2 as a center wheel and adopting the pull rod 23 as a swiveling jib can revolute around the power shaft 20 and rotate, and is respectively in cross-over connection with the power wheel 2 and the alligatoring ring frame 1, though transmission parts such as wheel gears; the foreside and the rear are end respectively ganged with the power wheel 2 and the alligatoring ring frame 1; then the reciprocating movement of the alligatoring ring frame 1 can be transformed into the continuous rotating motion of the power wheel 2, and the continuous rotating motion of the power wheel 2 can alao be transformed into the periodic reciprocating movement of the alligatoring ring frame 1; said power changeover mechanism as well as engine and compressor etc. using the mechanism are characterized by simple structure, high transmission efficiency, high energy conversion efficiency, excellent discharging performances and the like.

Description

technical field [0001] The present invention relates to a power conversion mechanism for mutual conversion of reciprocating linear motion and rotary power; it also relates to a piston engine, a compressor, etc. using the power conversion mechanism. Background technique [0002] In the mechanical field, we often need to convert reciprocating motion and rotary power, especially piston engines (including gasoline, diesel, gas and other internal combustion engines, or steam engines, etc.), and piston air or refrigerant compressors, etc., their The main function needs to rely on this kind of power conversion mechanism to realize. [0003] The most widely used power conversion mechanism at present is the crankshaft-connecting rod mechanism. For example, since the piston engine was invented more than a hundred years ago, this traditional mechanism is still almost completely used; When the pressure is the highest, the rotational torque may be the small...

Problems solved by technology

[0003] The most widely used power conversion mechanism at present is the crankshaft-connecting rod mechanism. For example, since the piston engine was invented more than a hundred years ago, this traditional mechanism is still almost completely used; When the pressure is the highest, the rotational torque may be the smallest, but when the rotational torque gradually increases to the maximum, the working power has been attenuated by more than half; in addition, under the action of the constantly changing torque, the side pressure generated by the piston on the cylinder wall increases the resistance and intensifies the Wear between critical components

Its disadvantages are: because it adopts the design of "intermittent meshing between incomplete gear and rack", the teeth that mesh first will be subject to considerable impact, which will affect its service life; in addition, when the engine speed is in a large range When changing, the synchronous operation between the gear and the rack is not easy to control, and misalignment may occur, resulting in more serious consequences
