A kind of multifunctional pneumatic machine

Affiliated technical field

The present invention relates to pneumatic motor, the pneumatic motor of particularly a kind of piston and connecting rod non contact transmission energy.

Background technique

Pneumatic motor is the mechanical kinetic energy machine of compressed-air actuated potential energy converting and energy for rotation.Conversion regime has two big classes at present: rotary piston class and reciprocating piston class.

The rotary piston class directly is converted to the pressure of air and rotatablely moves, have simple in structure, volume is little, lightweight advantage, but the sealing technique complexity of rotary piston, poor air-tightness, maintenance difficulty in addition generally is used for the miniature pneumatic instrument.

For rotatablely moving, therefore advantage such as the reciprocating piston sealing technique has reliably, tightness is good, energy conversion rate is high, maintenance is simple has obtained utilization widely to the reciprocating piston class the pressure indirect conversion of air.But under existing, it shows shortcoming:

The first, to-and-fro motion being converted to the mechanism that rotatablely moves is connecting rod---crank mechanism, and many one deck mechanical mechanisms descend the whole mechanical efficiency of pneumatic motor with regard to many one deck mechanical losss.

The second, back and forth----rotation switching mechanism complex structure takes up room greatly, makes the pneumatic motor volume big, and weight increases.

Three, back and forth the mechanical motion of----rotation switching mechanism produces a large amount of heat, needs a cover liquid lubrication mechanism to guarantee its proper functioning.

Four, in high-power multi-cylinder pneumatic motor, the piston of each cylinder is by connecting rod--and-crank mechanism joins together mutually and pins down, and ties down mutually between each cylinder under light load condition, not only wastes energy, and brings unnecessary wearing and tearing.

Summary of the invention

At the shortcoming of back and forth----rotation pneumatic motor, the present invention makes reciprocal----rotating machinery into contactless magnetic force transmission by the mechanicals efforts transmission, improves the performance and the function of pneumatic motor.

The present invention in order to realize the technological scheme that its purpose adopts is: a kind of multifunctional pneumatic machine, comprise pressurized air I/O pipeline, power system, it is characterized in that, described power system comprises casing, cylinder, piston, rotor, stator, pto, casing is the shell of power system, it is horizontal cylindric that main body is, uniform at least one cylinder on the radial cross section of casing, the central shaft of cylinder overlaps with a diameter in casing cross section, cylinder wall and casing are in aggregates, the mouth that joins with pressurized air I/O pipeline is arranged on the cylinder, piston is in cylinder, can be along the cylinder axial motion, stator is a U-shaped permanent magnet, magnetic pole with two projectioies, its bottom joins with piston, when piston runs to lower dead center, two extended pistons of projection of U-shaped permanent magnet, pto axially passes casing central authorities, itself and casing join by bearing, rotor is the disk of leaf lobe type, each leaf lobe has magnetic, and two magnetic pole magnetic pole divides routine leaf lobe both sides, and rotor is installed on the casing internally-powered output shaft, can drive the pto rotation, when stator with piston motion when the lower dead center, two of the U-shaped permanent magnet projectioies can be wrapped up the leaf lobe of rotor on the stator, the magnetic pole of stator is adjacent with the epitrochanterian magnetic pole same sex.

Described cylinder and piston in combination are four, are evenly distributed on respectively on the casing longitudinal cross-section.

Described rotor is the disk with leaf lobe type of three leaf lobes.

On pto, be equipped with information disk.

Outside casing, also include with micro-processor controlled suction valve and outlet valve, be installed in the both sides of the mouth that joins with pressurized air I/O pipeline on each cylinder respectively.

Beneficial effect of the present invention

The first, magnetic transmits pneumatic motor and saves complicated connecting rod---crank mechanism, simple in structure, volume is little, in light weight.

The second, reciprocal----rotation conversion of magnetic transmission pneumatic motor is contactless, nothing rubs, empty calory, need not liquid lubrication mechanism, mechanical efficiency height, energy conversion rate height.

Three, magnetic transmits pneumatic motor, and each cylinder piston motion is separate, and microcomputer is controlled each cylinder acting according to loading condition.Under light load condition, can do work by a cylinder, other cylinder is had a rest, and not only saves the energy, and reduces unnecessary wearing and tearing, improves working life.

Four, transmit pneumatic motor toward magnetic, by each cylinder acting of microcomputer control, can output power, also can export multiple motion mode, one-machine-multi-function.
