Problems solved by technology

When the piston compresses the gas, the stroke of the piston is not proportional to the back pressure on the piston after the gas is compressed. The above defects are unavoidable in the piston crankshaft and connecting rod mechanism. This defect seriously affects the structural performance of the piston compressor and piston engine. There is an urgent need for a piston speed change mechanism that adapts to changes in gas pressure to replace the existing piston crankshaft linkage mechanism. I applied for a patent on June 27, 2014, application number: Patent name: with a rotary piston speed change mechanism Fluid power machinery, but this invention still has defects such as complex structure and poor stability, and needs to be further improved

Abstract

The invention relates to a fluid dynamic machine with a turning wheel transmission piston speed-changing mechanism. The fluid dynamic machine comprises a machine body (1), an air cylinder piston linkage mechanism (2) and a turning wheel transmission mechanism (3), wherein a turning wheel disc (11) and a transmission shaft (10) of the turning wheel transmission mechanism (3) are concentrically or eccentrically mounted, a turning wheel groove (13) is formed in a disc surface (14) of the turning wheel disc (11), a turning wheel body (12) is supported and mounted in the turning wheel groove (13) through a bearing, a rotating shaft (18) is mounted on the turning wheel body (12), and a connecting rod sleeve (9) at the tail of a connecting rod (6) sleeves the outer part of the rotating shaft (18); the turning wheel disc (11) rotates, and the turning wheel body (12) drives the connecting rod (6) and a piston (6) to do the variable-speed reciprocating motion.

Description

technical field [0001] The invention relates to a rotary transmission piston transmission mechanism for fluid machinery and engines, and relates to the technical field of fluid power machinery manufacturing such as fans, compressors, expansion power machines and engines. Background technique [0002] What used piston compressor and piston engine adopted at present is a piston crankshaft connecting rod mechanism, and the piston crankshaft connecting rod mechanism becomes the reciprocating motion of piston by crankshaft rotation. When the piston compresses the gas, the stroke of the piston is not proportional to the back pressure on the piston after the gas is compressed. The above defects are unavoidable in the piston crankshaft and connecting rod mechanism. This defect seriously affects the structural performance of the piston compressor and piston engine. There is an urgent need for a piston speed change mechanism that adapts to changes in gas pressure to replace the existi...
