Technical Field

The invention relates to a mechanical technology, in particular to a pneumatic engine.

Background

Pneumatic engines are widely used in many fields, from the earliest steam locomotives to modern pneumatic automobiles, and are mainly used for various pneumatic mechanical accessories originated from air compressors, such as pneumatic wrenches, air cannons and the like.

Disclosure of Invention

The invention aims to provide a pneumatic engine aiming at the defects of the prior art. The pneumatic engine has the advantages of low cost, simple assembly, high air conversion efficiency, low noise and the like.

The technical scheme for realizing the purpose of the invention is as follows:

a pneumatic engine comprises a hollow air distribution pipe and an air distribution rotating shaft, wherein a front support and a rear support are respectively arranged at two ends of the air distribution pipe, a first vent hole and a second vent hole with upward openings are arranged on the air distribution pipe, the connecting line of the central point of the first vent hole and the central point of the second vent hole is parallel to the central axis of the air distribution pipe, a first vent pipe and a second vent pipe which take the central axis of the air distribution pipe as a symmetry line are symmetrically arranged on the air distribution pipe, the central axes of the first vent pipe and the second vent pipe are both vertical to a plane formed by the connecting line of the central point of the first vent hole, the central point of the second vent hole and the central point of the central axis of the air distribution pipe, the outer ends of the first vent pipe and the second vent pipe are respectively connected with a first cylinder and a second cylinder, the first cylinder and the second cylinder are fixed on the front support, a first piston with a first connecting rod and a second piston with, the air distribution rotating shaft sequentially penetrates through the rear support, the air distribution pipe and the front support and can rotate freely, the outer wall of the air distribution rotating shaft is tightly attached to the inner wall of the air distribution pipe, the air distribution rotating shaft is sealed and airtight, one end of the air distribution rotating shaft penetrating through the front support is provided with an eccentric driving rod deviating from the central axis of the air distribution rotating shaft, the eccentric driving rod is respectively connected with one outward end of the first connecting rod and one outward end of the second connecting rod, the outer wall of the air distribution rotating shaft wrapped in the air distribution pipe is provided with a first groove and a second groove in a closed ring shape, the distance between the central line of the first groove and the central line of the second groove is equal to the distance between the central points of the first vent and the second vent, namely, the first groove is always communicated with the first vent, the second groove is always communicated with the second vent when the air distribution rotating shaft rotates, the first concave surface is milled on, the first concave surface is not communicated with the second groove, a second concave surface with the same shape as the first concave surface is milled at the opposite position of the other surface of the outer wall of the air distribution rotating shaft along the second groove to the direction of the first groove, the second concave surface is not communicated with the first groove, and the first concave surface and the second concave surface are communicated with the first vent pipe and the second vent pipe in turn when the air distribution rotating shaft rotates.

When the gas distribution rotating shaft rotates clockwise to the first concave surface and is communicated with the first vent pipe, gas enters the first groove through the first vent hole and then enters the first cylinder through the first vent pipe, the gas pressure pushes the first piston in the first cylinder to move outwards, the first piston pushes the first connecting rod to move, the first connecting rod continuously pushes the gas distribution rotating shaft to accelerate clockwise movement through the eccentric driving rod, at the moment, the eccentric driving rod pushes the second connecting rod to move, so that the second piston moves in the second cylinder to compress air in the second cylinder, the compressed air is discharged from the gas distribution pipe through the second vent pipe, the second groove and the second vent hole, when the eccentric driving rod moves to the farthest end away from the first cylinder, the first piston finishes driving, at the moment, the second groove is communicated with the second vent pipe, the gas starts to enter the second cylinder through the second vent pipe and pushes the second piston to move outwards, the second piston pushes the eccentric driving rod through the second connecting rod, so that the air distribution rotating shaft continues to accelerate clockwise, meanwhile, the first piston discharges the gas in the first cylinder out of the air distribution pipe through the first vent pipe and the first vent hole, and the air distribution rotating shaft is in a cycle, so that the circulating rotating motion of the air distribution rotating shaft can be realized by air filling and compacting of the first vent hole.

The pneumatic engine has the advantages of low cost, simple assembly, high air conversion efficiency, low noise and the like.
