Embodiment
As depicted in figs. 1 and 2, non-link rod reciprocating piston engine capable of changing output speed of the present invention, comprise cylinder sleeve 4, following cylinder sleeve 12 and output mechanism, be provided with reciprocating piston 5 between last cylinder sleeve 4 and the following cylinder sleeve 12, reciprocating piston 5 top and bottom are provided with piston ring 6, last cylinder sleeve 4 tops and following cylinder sleeve 12 bottoms are provided with spark plug 2, intake valve 1 and exhaust valve 3, described output mechanism comprises rotary-piston 7-1 and is fixed on the eccentric shaft 7-2 of 7-1 on the rotary-piston, be fixed on the circular limited ring 8 on the pedestal 14 and be arranged on pto 11 on the bearing support 15, rotary-piston 7-1 is arranged in the round hole 13 in the reciprocating piston 5 and can rotates in circle hole 13, the eccentric shaft 7-2 end of passing circular limited ring 8 is provided with planetary pinion 9, and pto 11 is provided with the sun gear 10 that meshes with planetary pinion 9 near circular limited ring 8 central positions.In addition, described circular limited ring 8 inside radiuss are the throw of eccentric of eccentric shaft 7-2 and the radius sum of eccentric shaft 7-2, like this, the rotating speed of pto 11 equals the rotating speed sum that sun gear 10 is passed in planetary pinion 9 revolution rotating speeds and planetary pinion 9 rotations, so non-link rod reciprocating piston engine capable of changing output speed of the present invention has the variable characteristics of output speed, can design different output speeds by different application, when circular limited ring 8 internal surfaces are smooth, the present invention approximately is the twice of old-fashioned engine speed, when circular limited ring 8 changes the ring that has internal tooth into, also has an output at a slow speed.Output mechanism of the present invention also is applicable to the motor that four cylinders are above, and the present invention is that example illustrates working principle of the present invention with the twin cylinder engine just.
As shown in Figure 3, described eccentric shaft 7-2 two cephalic pars are provided with the identical planetary pinion of the number of teeth 9, be fixed on the circular limited ring 8 on the pedestal 14 and be arranged on pto 11 on the bearing support 15, pto 11 next doors are provided with the lazy-tongs that make eccentric shaft 7-2 two ends revolution synchronous, eliminate the unbalanced of the revolution simultaneous bias of eccentric shaft 7-2 and the suffered side pressure of rotary-piston 7-1; Described lazy-tongs are made up of synchronizing shaft 16 and the synchromesh gear 17 that is fixed on synchronizing shaft 16 two ends, sun gear 10 engagements on synchromesh gear 17 and the pto 11.
As shown in Figure 4, reciprocating piston 5 moves downward, the upper cylinder air inlet, the lower cylinder exhaust, rotary-piston 7-1 and planetary pinion 9 turn clockwise, and the planetary pinion 9 clockwise rotations and the sun gear 10 that revolves round the sun around sun gear 10, and drive counterclockwise are rotated counterclockwise outputting power.
As shown in Figure 5, reciprocating piston 5 moves downward, the upper cylinder air inlet, the lower cylinder exhaust, rotary-piston 7-1 and planetary pinion 9 turn clockwise, and planetary pinion 9 clockwise rotations are also revolved round the sun around sun gear 10 counterclockwise, and drive sun gear 10 is rotated counterclockwise outputting power, the mutual constraint that turns to of planetary pinion 9 and sun gear 10, rotary-piston 7-1 and planetary pinion 9 are one, so rotary-piston 7-1 can not reverse at this moment.
As shown in Figure 6, reciprocating piston 5 moves to minimum point, and the upper cylinder air inlet is finished, and the lower cylinder exhaust is finished, and planetary pinion 9 moves to minimum point.
As shown in Figure 7, reciprocating piston 5 moves upward, the upper cylinder compressed mixed gas, and the lower cylinder air inlet, the planetary pinion 9 clockwise rotations and the sun gear 10 that revolves round the sun around sun gear 10, and drive counterclockwise are rotated counterclockwise outputting power.
As shown in Figure 8, reciprocating piston 5 moves to top dead center, to the upper cylinder igniting, and blast, gas promotes reciprocating piston 5 and moves downward, and lower cylinder begins compressed mixed gas.
As shown in Figure 9, reciprocating piston 5 moves upward, the upper cylinder exhaust, and the explosion gas of lower cylinder promotes reciprocating piston 5 and moves upward, the planetary pinion 9 clockwise rotations and the sun gear 10 that revolves round the sun around sun gear 10, and drive counterclockwise are rotated counterclockwise outputting power.
As shown in figure 10, when reciprocating piston 5 moves downward, eccentric shaft 7-2 is in left side, rotary-piston 7-1 medial axis, and eccentric shaft 7-2 plays point action, rotary-piston 7-1 is subjected to downward power, prop up dot center and take back, so rotary-piston 7-1 turns clockwise-rotation, eccentric shaft 7-2 moves downward-revolves round the sun along circular limited ring 8 simultaneously.
As shown in figure 11, when reciprocating piston 5 moves upward, eccentric shaft 7-2 is on right side, rotary-piston 7-1 medial axis, and eccentric shaft 7-2 plays point action, rotary-piston 7-1 is subjected to power upwards, prop up dot center and take over, so rotary-piston 7-1 turns clockwise-rotation, eccentric shaft 7-2 moves upward-revolves round the sun along circular limited ring 8 simultaneously.
Rotary-piston goes at top dead center position the rotating rule disorder can not occur when 90 degree or 270 are spent, because except that above-mentioned reason, the mutual constraint that turns to of planetary pinion 9 and sun gear 10, rotary-piston 7-1 and planetary pinion 9 are one, so rotary-piston 7-1 reversal phenomenon can not occur at this.
