Abstract

The utility model provides a rotary wheel interconnected cylinder internal-combustion air compressor, in which an internal combustion power cylinder, a piston and an air compression cylinder, and a piston are combined into a whole. The rotary wheel interconnected cylinder internal-combustion air compressor can do work coaxially by a single cylinder, a plurality of cylinder, a single piston and a plurality of piston, having the advantages of low specific fuel consumption, light specific weight, small specific volume and specific cost saving. The utility model is composed of a multi-cylinder coupled crank shaft sheathed with a flywheel, a piston pin connected with an external gear, a double-ended piston shifted by the piston pin in reciprocation, the air cylinder of an internal-combustion engine, an air compression cylinder, an internal gear, etc. In the utility model, the traditional internal loss of the work which is output by the crank shaft and a connecting rod is omitted. The rotary wheel interconnected cylinder internal-combustion air compressor which has the advantages of light weight and is suitable for mobile pneumatic machines can be widely used for earth and rock cutting works on mining areas, roads, etc.

Description

Rotary wheel interconnected cylinder IC air compressor

The utility model relates to a kind of air compressor, and especially a kind of is the rotary wheel interconnected cylinder internal combustion air compressor of power with the internal-combustion engine.

Existing air compressor is a power with internal-combustion engine or motor, and reciprocating piston or vane pump are the composite structure of air compressor, and so device certainly will consume certain conversion and transmit merit, and weight/power ratio, specific volume, all is difficult for economization than cost.

The purpose of this utility model provides a kind of with combustion power cylinder, piston and air compression cylinder, piston coenosarc, but single cylinder, multi-cylinder, single piston, the coaxial work done of many pistons, thus realize that specific fuel consumption is low, and weight/power ratio is light, specific volume is little, than the serial internal combustion air compressor of cost province.

The utility model is by inside and outside gear, and wrist pin, cylinder of internal-combustion engine, air compression cylinder, multi-cylinder interlock bent axle, flywheel and double-head piston are formed.

Further describe below in conjunction with accompanying drawing.

Fig. 1 is a hypocycloid m=2 track schematic representation.

Fig. 2 creates into duplex cylinder internal combustion air compressor structural representation for cycloid.

The utility model Structure Mechanism is taken from the hypocycloid equation of the cycloid of mathematical theory.Its definition is: a circumference rolls along the inside of another circumference and when fricton-tight, curve of a bit being retouched on the circumference.The utility model design equation parameter is got A/a=m=2.A is moving circle radius in the formula, and A is for to decide circle radius, and as Fig. 1, (1) is fixed round ring gear among the figure, and (2) are the circle external gear, and (3) are round go up more (being wrist pin), and (9) are that on the circle a bit be the track of wrist pin linear reciprocating motion.Fixed circle is fixed on the support, and moving circle is realized rotation and revolution with bent axle for bearing ordering about of bent axle, and rotation is that m is a to-and-fro motion of wrist pin (3) do with the ratio of revolution.The double-head piston (7) that place double-end cylinder this moment is under the stirring of wrist pin (3), and internal-combustion engine air compressor program is routinely worked respectively in cylinder (4), (8), realizes directly transmitting the internal combustion air compressor work overall process of merit.The main function of bent axle is in order to connect a plurality of so two-way ram work and accept the inertia of flywheel control.

As Fig. 2, the internal gear (1) of this rotary wheel interconnected cylinder internal combustion air compressor is fixed on the support, be with multi-cylinder interlock bent axle (5) the supporting external gear (2) of flywheel (6), the wrist pin (3) that connects external gear (2) double-head piston (7) with bearing housing, and two is respectively cylinder of internal-combustion engine (4) and air compression cylinder (8).Feature of the present utility model is: as the air compressor that combustion power drives, it is to be finished in the duplex cylinder body by the double-head piston of straight reciprocating motion that its conversion is transmitted, and has saved traditional in-fighting of passing through bent axle, link rod output work.

Rotary wheel interconnected cylinder internal combustion air compressor conversion loss of the present utility model is little, and weight/power ratio is light, is applicable to portable pneumatic machinery, can be widely used in the cubic metres of earth and stone such as mine, road and dig engineering.
