Embodiment
Have the motor that rotates link pin and comprise piston 1, cylinder 2, connecting rod 3, connecting rod rotating dog gear 4, connecting rod rotating dog 5, bent axle 6, crankpin 7, double sided gear 9 and other gear 10,11,12 (Fig. 1,2,3,4,5).
By connecting rod rotating dog 5, connecting rod 3 one ends are connected on the piston 1, and an end is connected on the bent axle 6.The connecting rod rotating dog gear made from connecting rod rotating dog 54 moves on crankpin 7.Connecting rod rotating dog gear 4 and connecting rod rotating dog 5 can be used as an integral body and make, and assemble up after perhaps making respectively.Similarly, gear 11 and 12 can be used as an integral body and makes, and assembles up after perhaps making respectively.
The gear 9 that inner and outer surface all has wheel tooth is located on the axle of bent axle 6.Described gear 9 links with connecting rod rotating dog gear 4 and moves with connecting rod rotating dog gear 4, and wherein connecting rod rotating dog gear 4 is positioned on the crankpin 7 and with connecting rod rotating dog 5 and links to each other.Described gear 10,11,12 interconnects and is connected on the bent axle 6, by driving the connecting rod rotating dog gear 4 that links to each other with connecting rod rotating dog 5 is moved in double sided gear 9 and they.
The counterrotating on crankpin 7 of connecting rod rotating dog gear 4, rotating amount equal the poor of bent axle 6 and double sided gear 9 rotating amounts.When bent axle 6 rotations, described double sided gear 9 rotations on being supported on bent axle 6 axis of connecting rod rotating dog gear 4 and connecting rod rotating dog 5.But rotatablely moving of bent axle 6 is different with described gear 9, and because this rotating speed difference, connecting rod rotating dog gear 4 makes the axis rotation of connecting rod rotating dog 5 around crankpin 7.
In this rotatablely moves, because the axis of connecting rod rotating dog gear 4 and connecting rod rotating dog 5 is different, so connecting rod rotating dog 5 axis are around the axis rotation of connecting rod rotating dog gear 4 and crankpin 7, and because the difference of axis, the rotating center of connecting rod 3 changes in rotary movement.
When the connecting rod rotating dog gear 4 with 5 motions of connecting rod rotating dog makes connecting rod 3 motions,, directly do not depend on the motion of crankpin 7 although connecting rod 3 links to each other with piston 1 with bent axle 6; The motion of bent axle 6 is independent of connecting rod 3.This has produced difference between the rotating diameter of stroke of piston route between the last lower dead center and crankpin 7.In this case, connecting rod 3 carries out elliptic motion on crankpin 7, rather than circular movement.
Explained later also shows that in Fig. 2 and 3 connecting rod rotating dog gear 4 rotates the motion of the piston 1 under the half-turn situation when bent axle 6 changes a whole circle.
The operating procedure of motor when figure 2 illustrates piston 1 and from the top dead center to the lower dead center, moving downward.
Connecting rod 3 be centered close to the position higher than the axis of crankpin 7, wherein the axis of crankpin 7 and connecting rod rotating dog 5 moves into straight line.In this case, piston 1 applies bigger pressure by connecting rod 5 to crankpin 7, in addition, because the motion at connecting rod 3 centers makes bent axle 6 rotating moment arms big, so the bigger rotating force that on bent axle 6, forms.And, except acting on, connecting rod 3 makes on the crankpin 7 bent axle 6 rotation, and double sided gear 9 and other gear 10,11,12 also impel bent axle 6 rotations.Because too much pressure and moment loading are on bent axle 6, the power of motor has been strengthened.
Fig. 2 also shows when piston 1 moves upward from the lower dead center to the top dead center, the operating procedure of motor.In the described movement process of piston 1 in cylinder 2, connecting rod 3 be centered close to the position lower than crankpin 7, wherein the axis of crankpin 7 and connecting rod rotating dog 5 moves into straight line.When piston 1 carries out described moving upward than bent axle 6 slowlyer, more weak at the opposite force that exhaust stroke acts on the piston 1, easier thereby bleeding becomes.
As shown in Figure 3, the length of piston 1 in cylinder 2 is more a little than the length shown in Fig. 2.In this case, enter cylinder 2, can produce motor efficiently by allowing more air-fuel mixture.
In Fig. 4, can see that turn around if connecting rod rotating dog gear 4 revolves to revolve when turning around at bent axle 6, then crankpin 7 rotation round diameters are bigger than the length of stroke of piston 1 in cylinder 2.
In having the motor that rotates link pin, when piston 1 moves downward from the top dead center to the lower dead center than crankpin 7 slowlyer, high pressure is used more effectively, and allows to use the fuel of low rate of combustion and make high speed engine, particularly for diesel-fueled engine.
Can also use chain, sprocket wheel, electronics and hydraulic system substitute all gears that use in the utility model.In addition, because timing can cause spark delay to reduce in advance in petrol engine,, thereby can produce quieter and motor more efficiently so the opposite force that acts on the piston 1 is littler.Make the motor to be manufactured on the thermomechanics effectively and can not to diminish environment the firing time of reserving.And, good igniting and high efficiency can be provided in two-stroke engine.
