Description
Technical field

Background technique
In the prior art at present, reciprocating engine, compressor and some otherly need to carry out straight reciprocating motion and generally adopt connecting rod to realize motion conversion with the machinery of the conversion mutually that rotatablely moves.
Traditional Design of Crank and manufacture are very perfect, still, no matter from theory analysis, or aspect practical application, all have obvious shortcoming:
1. connecting rod conversion efficiency is lower.Piston-connecting rod-bent axle (handle) mechanism engine of take is example, and it is upper that the combustion gas pressure of explosion of piston is delivered to bent axle (handle) through connecting rod, and bent axle (handle) is converted into moment of torsion outputting rotary power.How much mechanisms of bent axle (handle) connecting rod and motion thereof and stress are more complicated, and all parts is all in complicated three-dimensional stress state.Because crankshaft & connecting has upper and lower stop and connecting rod swing, the igniting of cylinder combustion gas must arrange ignition advance angle, now act on gaseous-pressure on piston be broken down into along the active force of connecting rod axial direction and perpendicular to cylinder axis directive effect the side pressure at casing wall, along connecting rod axial force, act on bent axle, be decomposed into again vertical crankshaft radial direction tangential force and along the normal force of radial direction, the tangential force that gaseous-pressure obtains after decomposing is much smaller than the gaseous-pressure acting on piston.The side pressure that acts on casing wall makes piston and casing wall produce very large frictional force, the uneven rotating mass rotation motion of crankshaft & connecting produces inertial force, piston axis direction total force equals to act on the algebraic sum such as gaseous-pressure and inertial force on piston, frictional force, and inertial force and frictional force are always contrary with gaseous-pressure action direction, piston axis direction total force is less than the gaseous-pressure acting on piston, by piston axis direction total force, produces bent axle tangential forces much smaller than the gaseous-pressure acting on piston.Engine output power square equals tangential force and crank throw is long-pending, and the moment of torsion of therefore being exported by bent axle tangential forces is much smaller than the moment of torsion of directly being changed by the gaseous-pressure acting on piston.Above-mentioned analysis shows that the conversion efficiency that crankshaft & connecting is converted to uniform circular motion by straight reciprocating motion is lower, and by crankshaft & connecting, to export useful work power lower for gaseous-pressure.Calculating shows that a motor is 10 to spend time igniting at ignition advance angle, and now piston total force is that maximum force only has 21 percent left/right rotation to be changed to the tangential forces that produces bent axle moment of torsion;
2. the gaseous-pressure that in crankshaft & connecting, connecting rod swing makes to act on piston produces the lateral pressure that vertically acts on casing wall, increased side-friction force between piston and casing wall is increased, the wearing and tearing of acceleration cylinder wall, not only reduced the mechanical efficiency of piston, but also can cause " card cylinder " that piston cannot be worked.The uneven rotating mass rotation motion of crankshaft & connecting produces inertial force not only affects the output power of motor, and makes motor produce vibration and noise;
3. because the upper and lower stop of bent axle is corresponding one by one with the upper and lower stop of piston, crankshaft rotating diameter equals piston stroke, accumulated energy flywheel need be set, make bent axle cross atdc igniting, in time of ignition cylinder body, gas pressure contracting is in maximum rating than not, reduce the time of ignition combustion gas outburst swelling pressure, simultaneously because flywheel exists the resistance that has increased startup and speed change.
