Abstract

The invention relates to a cam-type air compressor. A cam (9) is fixed on a power shaft (1); an air cylinder (6) is arranged an air cylinder fixed shaft (4) of a bracket (3) and can swing; the air cylinder fixed shaft (4) is fixed on the bracket (3); an oscillating bar (5) is movably arranged on the bracket (3) and can swing; the oscillating bar (5) is contacted with the cam (9) through an oscillating bar roller (11); a piston rod of the air cylinder (6) is movably connected with the oscillating bar (5); and the bracket (3) is fixed by a fixed base (2). When the cam-type air compressor operates, the power shaft (1) and the cam (9) rotates, the oscillating bar (5) is pushed by the cam (9); the oscillating bar (5) transfers thrust to the piston rod of the air cylinder (6); and compressed air generated by the air cylinder (6) is outputted outwards through an exhaust pipe (8). When the oscillating bar roller (11) on the oscillating bar (5) rolls over the culminating point of convex teeth of the cam (9), the oscillating bar (5) swings inwards under the action of a return spring (10) of the oscillating bar, so that the piston rod of the air cylinder (6) is driven to extrude, a negative pressure is generated in the air cylinder (6), and the air cylinder (6) performs air suction through an air filter (7); and when the next convex tooth of the cam (9) arrives, the processes of air compression and exhaust of the next time are formed to perform reciprocating circulation.

Description

Cam-type air compressor

Affiliated technical field

Patent of the present invention relates to a kind of cammingly air compression plant, and doing work with the rotation of cam makes compressed-air actuated working cylinder reciprocating motion of the pistons produce pressurized air.

Background technique

Air compressor in the market all is bent axle, link rod structure.Promptly utilize the interior centre-crank shaft of rotating band engine-driven air compressor cylinder head of motor to rotate, make the connecting rod to-and-fro motion that is connected on the bent axle, promote reciprocating motion of the pistons and produce pressurized air, this equipment is to utilize electric energy to produce compressed-air actuated effective means.But utilize wind energy, when water can be produced pressurized air, adopting cam, swing link type structure is mode preferably, because that the diameter of cam can be designed is very big, on big cam radius, cam tooth can be set more, need not speed increaser just can increase the frequency of okperation of compression cylinder under the big slow-revving situation of moment, thisly produce pressurized air with the cam rotation mode and have its special applied environment and energy to utilize usefulness.

Summary of the invention

1: when cam following mechanical axis on the line shaft rotates, on the axle tilt fixing radially the variation of radius make the piston rod to-and-fro motion of air compression cylinder produce pressurized air by fork.The number of teeth of cam 〉=1, number of cylinders 〉=1, the cam number of teeth and number of cylinders are arranged in pairs or groups mutually and are made the work of the uniform countercylinder group of action of cam moment.

2: axle is fixed with cam, cylinder group and cylinder frame etc. rotate, the fork on the rotating turret and the piston rod of cylinder also make cylinder produce pressurized air moving reciprocatingly relatively, the number of teeth of cam 〉=1, arrange in pairs or groups mutually and make the work of the uniform countercylinder group of action of cam moment in number of cylinders 〉=1, the cam number of teeth and number of cylinders.

Structurally, if the force side of piston rod directly contacts with cam, tailpiece of the piston rod can be subjected to the effect of two power, one is the radial force that cam is given piston rod, this is the active force that needs, another power is the tangential force of cam to piston rod, this power can make the frictional force of piston and cylinder wall increase, cause excessive wearing and tearing, make the lost of life of cylinder and piston, so will increase a fork of eliminating tangential force between cam and piston rod, the tangential force of axle overhead cam just can not be delivered on the piston rod like this.Be provided with Returnning spring at fork, under the effect of Returnning spring power, drive piston and piston rod and inwardly move, at this moment cylinder suction.Outwards move at action of cam lower piston and piston rod, this moment cylinder compresses and discharge pressurized gas, the continuous production pressurized air of circulation like this.

The invention has the beneficial effects as follows, under the bigger situation of the slow moment of line shaft speed, need not speeder and just can produce pressurized air, capacity usage ratio height simple in structure by the reasonable use energy.

Description of drawings

Illustrate that below in conjunction with accompanying drawing the present invention is further described.

In the accompanying drawing: 1. line shaft, 2. fixed pedestal, 3. carriage, 4. cylinder stationary axle, 5. fork, 6. cylinder, 7. air filter, 8. outlet pipe, 9. cam, 10. fork return spring, 11 fork roller bearings.

Embodiment

Accompanying drawing cam (9) is fixed on the line shaft (1).Cylinder (6) is installed on the cylinder stationary axle (4) of carriage (3) and can swings, cylinder stationary axle (4) is fixed on the carriage (3), fork (5) is movably arranged on the carriage (3) and can swings, fork (5) is to contact by fork roller bearing (11) with cam (9), the piston rod of cylinder (6) and fork (5) flexibly connect, and carriage (3) pedestal (2) that is fixed is fixing.During work, line shaft (1), cam (9) rotate, and fork (5) is boosted by cam (9), and fork (5) passes to the piston rod of cylinder (6) with thrust, cylinder (6) produce pressurized air by outlet pipe (8) to outside output pressurized air.When the fork roller bearing (11) on the fork (5) rolls across the peak of cam (9) double wedge, fork (5) is inwardly swing under the effect of fork return spring (10), the piston rod that drive cylinder (6) this moment stretches out, cylinder this moment (6) forms negative pressure, and cylinder (6) is air-breathing by air filter (7).When next double wedge of cam (9) comes then, form the process of air compression and exhaust next time, reciprocation cycle.
