Definitions

  • the gear transmission of the engine includes an engine body, a crankshaft timing gear, a camshaft drive gear, a fuel injection pump gear, a crankshaft, and a camshaft.
  • the crankshaft is mounted in the body, and the crankshaft timing gear is mounted on the crankshaft.
  • the invention is driven by coaxially mounted large and small gears and first and second idle gears, and has a simple structure and a clear principle.
  • the gear chamber cover is positioned on the bottom plate through the cooperation of the concave hole and the shaft head, and the positioning is simple and reliable.
  • Figure 2 is a cross-sectional view taken along line A-A of Figure 1.
  • the pinion gear 5 meshes with the first idle gear 6 and the second idle gear 8, the first idle gear 6 meshes with the cam shaft drive gear 7, and the second idle gear 8 meshes with the fuel injection pump gear 9.
  • the camshaft drive gear 7 is mounted on the camshaft 13, and the fuel injection pump gear 9 is fastened to the output shaft 15 by bolts.
  • the gear ratio of the large gear 4 to the crankshaft timing gear 3 is 2: 1, and the number of teeth of the pinion 5 is equal to the number of teeth of the camshaft drive gear 7 and the fuel injection pump gear 9.

Abstract

L'invention porte sur des engrenages pour un moteur. Une plaque inférieure (2) est fixée sur un corps de moteur (1); un arbre central (11), un premier arbre d'engrenage baladeur (12), un arbre à cames (13), un second arbre d'engrenage baladeur (14) et un arbre de sortie (15) sont montés sur la plaque inférieure (2); un engrenage plus grand (4) et un engrenage plus petit (5) sont montés de manière coaxiale sur l'arbre central (11); l'engrenage plus grand (4) vient en prise avec un engrenage de distribution de vilebrequin (3); un engrenage entraîné par un arbre à cames (7) est monté sur l'arbre à cames (13); un premier engrenage baladeur (6) est monté sur le premier arbre d'engrenage baladeur (12) et un second engrenage baladeur (8) est monté sur le second arbre d'engrenage baladeur (14); l'engrenage plus petit (5) vient en prise avec le premier engrenage baladeur (6) et le second engrenage baladeur (8), respectivement; le premier engrenage baladeur (6) vient en prise avec l'engrenage entraîné par l'arbre à cames (7); le second engrenage baladeur (8) vient en prise avec un engrenage de pompe d'injection (9) qui est fixé sur l'arbre de sortie (15). Le volume de toute la boite d'engrenages est réduit, et il peut être assuré que les vitesses de rotation de l'engrenage entraîné par l'arbre à cames et de l'engrenage de pompe d'injection sont la moitié de celles de l'engrenage de distribution de vilebrequin.
