Arm piston linkage air compressor

Abstract

The invention discloses an arm-piston linkage type air compressor, which comprises a columniform cylinder, a transmission shaft and a compressing system arranged on the columniform cylinder, and the compressing system comprises four sets of air cylinders, pistons arranged in the air cylinders, a cam mechanism and four linked arms; the air cylinders are arranged on the cylinder wall of the columniform cylinder along the radial direction of the columniform cylinder, and the bottom of each air cylinder is provided with a one-way air inlet valve and a one-way air outlet valve; the cam mechanism is fixed on the transmission shaft and can rotate along with the transmission shaft, a flat cam is arranged at the center of the cam mechanism, and both ends of the cam mechanism are provided with symmetrically arranged driving parts; the arms are articulated end to end to form a linkage frame, moreover, the connected ends of the four arms are respectively articulated with the tails of the corresponding pistons, and the inner sidewall of each arm is provided with a working curve which is matched with a rotational locus; the cam mechanism drives the four arms to move together, so that the pistons are driven to act. The structure is simple and reliable, the manufacturing cost is low, and the efficiency is high.

Description

technical field [0001] The invention relates to the field of air compressors, in particular to an arm-piston linkage air compressor. Background technique [0002] At present, the air compressors that are widely used mainly include crankshaft crank piston type or twin-screw extrusion air compressors. The traditional crankshaft crank piston air compressors output power through the crankshaft, and drive the cylindrical cylinder piston device through the crank. The piston moves back and forth in a straight line, and the piston cooperates with the cylinder to complete the suction of air, and then compress and deliver high-pressure air. For the twin-screw extruding air compressor, it outputs high-pressure air through the high-speed rotation of the twin screws and the mutual extrusion of the threads of the two screws. [0003] However, for the above-mentioned crankshaft-crank piston air compressor, each cylinder works once for each revolution of the crankshaft, so the work efficie...

Problems solved by technology

[0003] However, for the above-mentioned crankshaft-crank piston air compressor, every revolution of the crankshaft, each cylinder works once, and the work efficiency is low, and the crankshaft and crank parts of the air compressor are difficult to machine, the production cost is high, and the machine is bulky , heavy weight, these shortcomings greatly limit the survival and development of the traditional crankshaft crank piston air compressor

As for the twin-screw extruding air compressor, it must be driven by strong power, which increases the cost of use, and the processing technology of the twin-screw is complicated, and various technical requirements are extremely high. In addition, compared with the traditional air compressor, its efficiency is not enough. 10%
