Embodiment
Two great institutions of the utility model shaft gear formula staight shank internal-combustion engine are made up of straight shank link lever mechanism and distribution device; The connecting rod 1 of straight shank link lever mechanism is connected with piston 6 by wrist pin 8, is fixed with tooth bar 2 on the connecting rod 1; There are two rotatingshafts 3 to be installed on the cylinder body in the shaft gear formula staight shank motor and can rotate, connecting rod 1 passes from the semicircular gear 4 on two rotatingshafts 3, all be fixed with on the every rotatingshaft 3 and transmit gear 5 and semicircular gear 4, transmit gear 5 and intermediate gear 11 engagements, semicircular gear 4 can or separate with tooth bar 2 engagements; Intermediate gear 11 is fixed in the cylinder body on the jack shaft 12 on the cylinder body, flywheel 10 is fixed on outside the cylinder body on the jack shaft 12 on the cylinder body; Timing gear be fixed on the jack shaft 12 or two rotatingshafts 3 in wherein rotatingshaft 3 on.
Install for convenience and make, the tooth bar 2 on the connecting rod 1 can separately be made connecting rod 1 and tooth bar 2 during fabrication and be fixed together, also can manufacture an integral body to connecting rod 1 and tooth bar 2; Semicircular gear 4 on the rotatingshaft 3 fits together after can separating manufacturing to rotatingshaft 3 and semicircular gear 4 during fabrication again, also can manufacture an integral body to rotatingshaft 3 and semicircular gear 4.Transmit the power of coming out in order to make rotatingshaft 3 can transmit connecting rod 1, the sense of rotation of shaft gear formula staight shank internal-combustion engine two rotatingshafts 3 when work angular velocity identical, rotation equates; Tooth bar 2 on connecting rod 1 can not mesh simultaneously with the semicircular gear 4 on two rotatingshafts 3, can only with semicircular gear 4 engagements on wherein the rotatingshaft 3.Can proper functioning for semicircular gear 4, semicircular gear 4 is half of an overall gear or fewer than half tooth.For power transmission efficiency that improves shaft gear formula staight shank internal-combustion engine and the loss that reduces power, adopt straight shank link lever mechanism to replace connecting rod, semicircular gear 4 on the rotatingshaft 3 and the tooth bar 2 on the connecting rod 1 have replaced the crank throw of the bent axle of connecting rod; Connecting rod 1 time is to do straight line motion in work, and when working stroke, the tooth bar on the connecting rod 1 promotes semicircular gear 4 and rotates, and when air-breathing, compression, exhaust stroke, is that semicircular gear 4 rotates and promotes connecting rod 1 and piston 6 is done straight line motion.
After the utility model shaft gear formula staight shank internal-combustion engine installs, pilot engine, flywheel 10 drives rotatingshafts 3 and rotates, and drives semicircular gear 4 again and rotates and promote connecting rod 1 and do straight line motion, makes piston 6 do air inlet, compression, acting, four stroke of exhaust in cylinder sleeve 7.During the motor proper functioning, the tooth of the semicircular gear 4 on rotatingshaft 3 continues rotation and promotes connecting rods 1 with tooth bar 2 engagements and piston 6 moves to lower dead center, air or burning mixture are sucked in firing chamber 9 and the cylinder sleeve, when piston 6 arrives lower dead center, the tooth of this semicircular gear 4 on one side separates with tooth bar 2, finishes intake stroke.At this moment, the tooth of the semicircular gear 4 of another side continues rotation and meshes with this tooth bar 2 on one side, promoting piston 6 moves and air or burning mixture in compression and combustion chamber and the cylinder sleeve to top dead center, when piston 6 arrives top dead center, the tooth of this semicircular gear 4 on one side separates with tooth bar 2, finishes compression stroke.At this moment, the inflammable mixture after the compression is lighted in air mixing burning after oil nozzle ejection high pressure fuel and the compression or spark plug discharge, the firing chamber internal cause breaks out and generation power, promoting piston 6 moves to lower dead center, promote connecting rod 1 to move again and make the tooth engagement of tooth bar 2 and the semicircular gear 4 that just rotates to this and promote semicircular gear 4 to continue rotation, when piston 6 arrived lower dead center, the tooth of this semicircular gear 4 on one side separated with tooth bar 2 again, finishes working stroke.At this moment, the tooth of the semicircular gear 4 of another side continues rotation and meshes with this tooth bar 2 on one side, promoting piston 6 moves and the waste gas after burning that promotes in cylinder sleeve and the firing chamber is got rid of outside the cylinder body to top dead center, when piston 6 arrives top dead center, the tooth of this semicircular gear 4 on one side separates with tooth bar 2 again, finishes exhaust stroke.Piston 6 constantly moves toward doing complex line with connecting rod 1, drives two rotations that rotatingshaft 3 does not stop.Semicircular gear 4 on every rotatingshaft 3 is when rotating, and the moving half-turn of revolution begins and tooth bar 2 engagements, rotates half-turn again and separates with tooth bar 2 again; The circulation that so goes round and begins again is carried out, and the transmission of power of generation is given flywheel.
