Description
Technical field
The utility model relates to a kind of mechanical transmission, and specifically a kind of will rotatablely moving converts the conversion equipment of to-and-fro motion or reverse conversion to.
Background technique
As everyone knows, with rotatablely move and the prior art of reciprocating mutual conversion in what extensively adopt is the crankshaft-link rod drive technology, for example application in internal combustion engine.As internal-combustion engine, make the heat energy that enters the fuel in the cylinder be transformed into mechanical energy efficiently, fuel is burnt under high as far as possible compression ratio, and must perfect combustion.Because the burning of fuel needs the regular hour, this just requires piston that a static time is arranged when top dead center, but because in crankshaft-linking rod drive mechanism, the to-and-fro motion that rotatablely moves with piston of bent axle is continuous interlock, it can not provide a static time to piston, thereby the fuel perfect combustion that can not guarantee to enter cylinder, can not efficiently heat energy be transformed into mechanical energy.
For this reason, Chinese patent ZL00233101.2 has proposed a kind of rotatablely moving and reciprocating new drive device, and it comprises bent axle, alien, rotator frame and the push rod that is connected described rotator frame one side at least; Described crankshaft installed is on crankshaft base, and it is made of main bottle neck, crank, inferior bent neck; Described rotator frame is installed between two cranks of described bent axle, and described alien is cylindrical, is arranged in the loose slot in the rotator frame, and is coupling with described bent neck; The upper and lower rotator frame loose slot that is provided with of described rotator frame; Described alien's loose slot has arcuate surface.During arcuate surface in the alien runs to loose slot, push rod will be done the stop of certain hour at top dead center, and this just provides the sufficient time for the burning of fuel, helps the abundant burning of fuel, improve the efficient of internal-combustion engine.Structure of drive device, because the spacing between the arcuate surface at the middle part of alien's loose slot is greater than the spacing between the parallel plane of two ends, after the alien enters the arcuate surface zone, under reciprocal action of inertia, can produce mechanical shock between alien and the loose slot, cause the device fluctuation of service, and easily cause parts to damage.
Summary of the invention
To be solved in the utility model is existing rotatablely moving and reciprocating conversion equipment fluctuation of service, the flimsy shortcoming of parts, and a kind of follow-on conversion equipment is provided.The technological scheme that addresses the above problem employing is: rotatablely move and reciprocating conversion equipment, comprise bent axle, alien, rotator frame and the push rod that is connected described rotator frame one side at least; Described crankshaft installed is on crankshaft base, and it is made of main bottle neck, crank, inferior bent neck; Described rotator frame is installed between two cranks of described bent axle, and described alien is cylindrical, is arranged in the loose slot in the rotator frame, and is coupling with described bent neck; The upper and lower rotator frame loose slot that is provided with of described rotator frame; Described alien's loose slot has at least one section arcuate surface, and has identical groove width.
Of the present utility model rotatablely move and reciprocating conversion equipment, because alien's loose slot has essentially identical groove width, so the alien can not produce mechanical shock when moving therein, makes whole device stable and reliable operation, and can improve working life.
When the terminal reality of push rod is used the parts that need do reciprocating linear motion can be installed, as piston.When the alien moved more than axis, it is up that piston is; When the alien moved below axis, it is descending that piston is.If axis is defined as the up angle that stops in advance with the driving angle of the pairing crankshaft-link rod of arc shaped surface on top, stop the angle and axis is defined as downlink delays with the driving angle of the pairing crankshaft-link rod of arc shaped surface of bottom, the stop angle that provided of rotator frame arc shaped surface is up angle and the downlink delays stop angle sum of stopping in advance so.Described alien's loose slot can be that central shaft is provided with axisymmetricly with the push rod, and bigger stop angle can be provided, and for fuel provides more period of combustion, but requires starter motor that bigger moment of torsion is arranged, and is fit to diesel engine.
Described alien's loose slot also can be asymmetric groove, push rod with the cambered surface on top less than the cambered surface of push rod with the bottom.The stop angle that rotator frame provided like this is less, but little to the torque demand of starter motor, is fit to petrol engine work.When push rod was reduced to limit position with the cambered surface on top, the up angle that stops in advance was zero, and the stop angle that this moment, the rotator frame arc shaped surface was provided equals downlink delays and stops the angle.
Described alien's loose slot can also have the continuous arcuate surface of plurality of sections, and the stop angle that its rotator frame arc shaped surface is provided can obtain by accumulative total.The width of best described alien's loose slot equals or is slightly larger than alien's diameter, guarantees alien's held stationary rolling-operation in loose slot.
