Abstract
The invention provides an annular double-piston engine, comprising a shell, an end cover, a piston and a spindle, wherein the shell is a round barrel, the shell forms a front cylinder compression chamber with a front end cover and a front piston, the shell forms a rear cylinder combustion chamber with a rear end cover and a rear piston, the middle part of the shell is provided with a guide slot, the front piston and the rear piston are connected by virtue of a connecting piece, the connecting piece is provided with a guide plate and a guide wheel, the guide plate is arranged in the guide slot, the spindle penetrates through the whole shell and is arranged at the position of a central axis, the spindle is provided with a convex column inside the shell, the convex column is provided with a groove which is in a sinusoid curve shape along the side of a cylinder, the groove divides the convex column into a front convex column and a rear convex column, and the guide wheel is placed into the groove and can move in the groove. The annular double-piston engine provided by the invention has main characteristics that: heat dissipation effect is good, and a water-cooling system or an air-cooling system can be simplified; structure is compact, and number of parts is low; and torque is high, rotating speed is low, the cam part of the spindle at the middle part is a reducer, and no additional reducer is required.
Description
Technical field
The invention belongs to a kind of annular double piston engine.
Background technique
At present, piston aviation engine still is widely used in middle-size and small-size aircraft, particularly as the power plant of General Aviation.Along with the continuous development of the design and fabrication technology of aircraft, its power plant are had higher requirement.And current most of piston aviation engine is to adopt constituent and retarder to slow down, and this must increase the weight of motor, reduces the power-weight ratio of motor, thereby reduces the Economy of motor.In the aeronautical technology field of " struggling for alleviating each gram weight ", it is valuable as gold to alleviate each gram weight.
Summary of the invention
The object of the invention just provides a kind of compact structure, makes simply, operates steadily, and has good scattering property, and the big annular piston motor of moment of torsion of pistons work generation.
Annular double piston engine of the present invention comprises housing, front cover, rear end cover, secondary piston, back piston, main shaft, and housing is a circular cylinder body; Cylinder plenum chamber before housing and front cover, secondary piston constitute, housing and rear end cover, back piston constitute cylinder firing chamber, back, and the housing medium position also has four guiding grooves; Secondary piston is connected through link with back piston, and guiding piece and guide wheel are housed on the link, and guiding piece is located in the guiding groove; And can be in guiding groove move left and right, main shaft is through whole housing, and is in the central axis position; Main shaft has a projection in enclosure interior, has the groove that is sinusoidal shape along cylindrical side on the projection, has two peak valleys on it; Groove has been divided into preceding projection and back projection to projection, and the integral body of preceding projection and back projection formation is as the retarder of motor, and guide wheel is placed in the groove; Can in groove, move, promote main shaft and produce moment of torsion, preceding cylinder plenum chamber is communicated with the outer tube of cylinder firing chamber, back through alignment of shafts through hole or housing.
Annular double piston engine of the present invention, combustion gas is the cylinder combustion chambers burn in the back, promotes back piston and travels forward; Thereby drive the preceding cylinder plenum chamber gas of secondary piston compression, meanwhile, guide wheel moves in curved slot; Make main shaft produce moment of torsion, one in piston back and forth, the main shaft half turn; Make main-shaft torque very big, the gas after the secondary piston compression can flow to cylinder firing chamber, back again through the outer tube of alignment of shafts through hole or housing, for cylinder firing chamber, back provides pressurized gas.
Annular double piston engine main characteristics of the present invention is: 1, good heat dissipation effect, can simplify constituent or air cooling system; 2, compact structure, number of spare parts is few; 3, moment of torsion is big, and rotating speed is low, and the cam portion of middle main shaft is exactly a retarder, does not need other retarder.
