Problems solved by technology

[0002] The currently used piston compressors and piston engines use a piston crankshaft connecting rod mechanism. The piston crankshaft connecting rod mechanism becomes the reciprocating motion of the piston through the rotation of the crankshaft; The back pressure of the piston is not directly proportional. The above defects are unavoidable for the piston crankshaft and connecting rod mechanism. This defect seriously affects the structural performance of the piston compressor and the piston engine. Replacement of existing piston crankshaft linkage

Abstract

The invention discloses a fluid dynamic machine with a rotary wheel piston speed change mechanism. The fluid dynamic machine is composed of a cylinder body (2), a piston (3), a sliding connecting rod (8), a transmission shaft (4), a rotary wheel transmission device (5) and an air distribution device (6), wherein a rotary wheel disc (51 )of the rotary wheel transmission device (5) of the rotary wheel piston speed change mechanism (1) is eccentrically arranged on the shaft body of the transmission shaft (4); a guide shaft (52) on the rotary wheel disc (51) and the sliding connecting rod (8) are linked with each other; the rotary wheel disc (51) rotates eccentrically; a piston (3) does decelerated motion along with the length change of the arm of force between the axis of the guide shaft (52) and that of the transmission shaft (4); under the driving of the sliding connecting rod (8), the piston (3) performs decelerated motion from a lower stop point (20) to an upper stop point (19) and performs accelerated motion from the upper stop point (19) to the lower stop point(20).

Description

technical field [0001] The invention relates to a piston-type runner-piston speed change mechanism for fluid machinery and engines, and relates to the technical field of fluid power machinery manufacturing such as pumps, hydraulic motors, air motors, compressors, expansion power machines and engines. Background technique [0002] The currently used piston compressors and piston engines use a piston crankshaft connecting rod mechanism. The piston crankshaft connecting rod mechanism becomes the reciprocating motion of the piston through the rotation of the crankshaft; The back pressure of the piston is not directly proportional. The above defects are unavoidable for the piston crankshaft and connecting rod mechanism. This defect seriously affects the structural performance of the piston compressor and the piston engine. Replace the existing piston crankshaft connecting rod mechanism. Contents of the invention [0003] The purpose of the present invention is to provide a vol...
