[embodiment]
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown in the figure, a kind of straight-shaft internal-combustion engine includes cylinder body 1 and body 2, in cylinder body 1, is provided with cylinder 3, in cylinder 3, is provided with piston 4, and piston 4 slidably reciprocates in cylinder body 1.
On the tooth bar slider 5, on body 2, be provided with main shaft 7 in tooth bar slider 5 in body 2, being provided with, piston 4 are connected to through connecting rod 6, main shaft 7 is provided with flywheel 8, in interior tooth bar slider 5, is provided with the intermittent gear 9 that is connected as a single entity with main shaft 7.Explosive power when utilizing burning down pushes away piston 4, and through tooth bar slider 5 is toward lower slider in connecting rod 6 promotions, the slip of interior tooth bar slider 5 then drives intermittent gear 9 and rotates, and intermittent gear 9 rotates and then drives main shaft 7 rotations, thereby realizes power output.
Specifically, said interior tooth bar slider 5 includes the interior tooth bar 10 of left and right both sides symmetry, connects through 11 transition of semicircle segmental arc between the left and right interior tooth bar 10.The tooth exterior string camber line 13 that the tooth of tooth bar 10 includes tooth depth wide 12 and is made up of to the exterior string arc line of D top line reticule in said.Said intermittent gear 9 includes the tooth depth wide 13 and the D top wide 14 that can contact and make piston 4 location with tooth exterior string camber line 13 that can contact and make piston 4 strokes with tooth depth wide 15.
