Crank-round slider mechanism, crank shaft thereof and equipment using same

Abstract

The invention discloses a crank-round slider mechanism, which comprises round sliders, a reciprocating component, a crank shaft and a machine frame, wherein the crank shaft comprises cranks positioned at two ends and main journals positioned between the two cranks; the cranks and the main journals have a common rotating shaft which is a crank rotating shaft; two coaxial crank pins extend out fromtwo ends of the main journal respectively to the end faces of the two cranks, which face the main journals; the distance between the axes of the two crank pin and the crank rotating shaft is e; the round slider is provided with an eccentric round hole; two round sliders having a phase difference of 180 degrees and fixed together are sleeved on each crank pin and the two round sliders of adjacent main journals have the same phase; the reciprocating component is arranged in a guide rail on the machine frame; each round slider can be rotationally arranged in a round slider accommodating hole of the reciprocating component; the guide rails of the reciprocating component corresponding to the round sliders with the same phase are arranged in parallel; and the guide rails of the reciprocating component corresponding to the round sliders with the phase difference of 180 degrees are vertical to each other. The mechanism of the invention can improve the bending resistance and deformation resistance of the crank shaft so that the stability of the mechanism is effectively improved. The invention also provides the crank shaft of the crank-round slider mechanism and equipment using the mechanism.

Description

technical field [0001] The invention relates to a mechanism for mutual conversion between reciprocating motion and rotary motion, in particular to a crank circular slider mechanism. The invention also relates to a crankshaft of the crank circular slider mechanism and a device using the mechanism. Background technique [0002] In conventional internal combustion engines and compressors, the conversion between the reciprocating motion of the piston and the rotational motion of the crankshaft is achieved by a crank-and-rod mechanism. However, due to the existence of the connecting rod, the internal combustion engine and compressor of the crank linkage mechanism have disadvantages such as bulky, heavy, and poor balance performance. [0003] In order to solve the problems referred to above, the Chinese patent whose approval announcement date is January 13, 1988 and whose announcement number is CN85100358B discloses a kind of "crank circular slider reciprocating piston internal c...
