Abstract
The utility model relates to a piston type internal combustion engine without a crankshaft, which is characterized in that a swing shaft is connected with a connecting rod piston group by a connecting rod tile in a cylinder body. A planetary wheel is connected with the swing shaft and is engaged with an external gear. Since the utility model adopts a scientific structure, the volume is reduced, and the weight is lightened. In the respect of power performance, the utility model not only solves the problems of vibration and noise, but also increases power angle at the same rotational speed. The utility model prolongs combusting time, and improves the economic performance of the internal combustion engine.
Description
The utility model relates to stroke piston combustion engine.
Piston was done linear reciprocating motion when existing stroke piston combustion engine was worked in cylinder, for the rotatablely moving of straight line motion transformation that makes piston must be used bent axle, China model utility bulletin CN2182268Y discloses partial gear of a kind of employing and a pair of tooth bar replaces crankshaft ﹠ connecting, drive the transmission shaft rotation with piston and replace crankshaft rotating, but there is following defective: when piston is done when pumping, to the topmost part or the easily damaged gear rack of foot generation impact force, and complex structure, the maintenance difficulty, poor durability.
The utility model purpose is to provide a kind of scientific structure, the Crankless piston internal-combustion engine that mechanical efficiency is high.
The realization the technical solution of the utility model is as follows: a kind of Crankless piston internal-combustion engine is characterized in that: in cylinder block, swing axis is connected with the connecting rod piston group by connecting rod bearing shell, and planet wheel connects swing axis and meshes with external gear.
External rotor is connected with swing axis, and external flywheel, internal rotor connect the swing axis of other cylinders.Above-mentioned cylinder can also can be arranged or the V-type arrangement by straight line type by 360 ° of opposed arrangements.
Owing to adopt the structure of the utility model science to make volume dwindle greatly, weight saving.Not only solve vibration and noise problem on the power performance, under same rotational speed, increased the acting angle, prolonged period of combustion, improved the Economy of internal-combustion engine.
Figure is cutd open in the side-looking of Fig. 1 the utility model.
Fig. 2 the utility model is faced and is cutd open figure.
Below in conjunction with accompanying drawing in detail embodiment is described in detail.
Embodiment: planet wheel and external gear engagement as shown in Figure 1, itself be that rotation is revolved round the sun again, swing axis is connected with the connecting rod piston group by connecting rod bearing shell on the one hand, be connected with planet wheel again on the other hand, so also rotation revolution again simultaneously, connecting rod promotes swing axis and drives planetary gear revolution when reciprocating motion of the pistons, because transferring to, the revolution of swing axis realization linear reciprocating motion rotatablely moves, as shown in Figure 2, swing axis drives the output of flywheel rotation realization power again around the revolution drive external rotor rotation of central axis, and internal rotor and other cylinder swing axiss are connected to form multi-cylinder engine.
So because a connecting rod straight line motion is not swung and needn't be considered that in the design of piston structure piston skirt is in order to overcome radial force and to play the guiding role.Make piston size can be reduced into original about 1/3 like this, and because compact structure, cylinder is arranged practicable 360 ° of opposed arrangements, except that the installation of considering other annex, engine design can be become a disc structure, promptly the every cylinder of 4 cylinder IC engines becomes 90 °, makes machine volume weight all dwindle or arrange by straight line type, V-type and also can.
