Description
Technical field
The utility model relates to a kind of body, in particular for back and forth-the mutually H type body of the mechanism of conversion rotatablely moves.The utility model relates to the equipment that uses this H type body simultaneously.
Background technique
In machinery, need to realize to-and-fro motion in many instances and rotatablely move between mutual conversion.For example, reciprocating internal combustion engine need be converted to rotatablely moving of bent axle with the linear reciprocating motion that piston produces under the pressure of explosion of burning mixture promotes; In contrast, compressor need be converted to external motor-operated crankshaft rotating the linear reciprocating motion of piston.Above-mentioned two kinds of conversions are except the driving link difference, and it is consistent that motion of mechanism is required, and therefore, can realize that linear reciprocating motion is converted to the mechanism that rotatablely moves, and can be used for also generally that realizing rotatablely moves is converted to linear reciprocating motion.
Some linear reciprocating motions are provided under the prior art and have rotatablely moved the mechanism of conversion mutually.Usually under the technology, adopt connecting rod to realize above-mentioned conversion.Present most of internal-combustion engine, compressor all use connecting rod.The characteristics of this mechanism are, need to be connected between linear reciprocating motion spare and the rotating motion part by the connecting rod that swings back and forth, because the motion of connecting rod is to swing back and forth, this motion is a kind of compound movement, is difficult to realize the complete equilibrium of inertial force, and the swing of connecting rod can increase the side pressure of piston to the motion guide rail sidewall, cause the increase of frictional force, in addition, the existence of connecting rod also makes this mechanism need to possess certain length on vibration-direction, makes its size be difficult to further dwindle.
In order to address the above problem, Chinese patent literature CN85100358B discloses a kind of " crankshaft circular slide block reciprocating piston internal combustion engine ", Chinese patent literature CN1067741C discloses a kind of " crank and double-round slide reciprocating piston internal combustion engine ", and Chinese patent literature CN1144880A discloses a kind of " crank and multi-round slide reciprocating piston internal combustion engine ".In addition, the application number that the applicant proposed on October 16th, 2009 is in 200910236026.5 the Chinese patent application, also to have proposed a kind of axle system that adopts end axle-moving axis to be combined to form cooperates formation with reciprocating part reciprocal-rotation movement mutual conversion mechanism.
The common feature of above-mentioned novel rotation-reciprocal switching mechanism is not re-use connecting rod as to-and-fro motion and the middle transition element that rotatablely moves, and has avoided because the problem that connecting rod causes.At first, because the compound movement that does not exist connecting rod to introduce, make that all elements all are in the simple harmonic motion state in the motion, be convenient to carry out reciprocal inertia force and rotatory inertia equilibrium of forces, and can realize real complete equilibrium.Secondly, owing to do not have connecting rod, make no longer to exist for the size of arranging connecting rod and increasing on the to-and-fro motion track, the bulk that entire mechanism is occupied is able to remarkable minimizing.
Owing to there is not a connecting rod, above-mentioned back and forth-spatial arrangement of rotary motion conversion mechanism is also different with the connecting rod of existing common technology.Especially for the above-mentioned novel rotation with three to-and-fro motion elements-back and forth switching mechanism, not only can realize the complete equilibrium of its reciprocal inertia force and reciprocal inertia force square, and entire mechanism is arranged in the body of compact structure.In the body that provides for above-mentioned three to-and-fro motion elements, a kind of typical form is a H type body.
