Fig. 1 is the schematic perspective view of inventive principle and structure.
Fig. 2 is cluster gear and fuel injection pump gear and other idle pulley syntagmatic schematic diagrams.
Specific embodiment
The structure of the present invention is described further below in conjunction with accompanying drawing and by embodiment, but the present invention is covered
Content is not limited to following embodiments.
The timing gears architecture of lubricating oil pump and compression pump is driven, its composition structure is：Timing gear train be provided with four it is lazy
Wheel, the first idle pulley 2 is three layers of cone pulley structure, and the ground floor gear 2-1 lower right-hand sides of the first idle pulley are engaged with crankshaft toothed wheel 1；The
The second layer gear 2-2 of one idle pulley is engaged with fuel injection pump gear 3；A left side of the third layer gear 2-3 of the first idle pulley and the second idle pulley 4
Engage lower end.Engage with the 3rd idle pulley 5 upper end of the second idle pulley；The upper right side of the 3rd idle pulley is engaged with cam shaft gear 6.Bent axle
The left end of gear is engaged with oil pump gear 7；The right-hand member of crankshaft toothed wheel is engaged with the 4th idle pulley 8；The right-hand member of the 4th idle pulley and pressure
Air pump gear 9 is engaged.Crankshaft toothed wheel operates as timing gear train described in active wheel drive.
In said gear, crankshaft toothed wheel, the first idle pulley and cam shaft gear are carved with timing marks, respectively：Crank teeth
The timing marks of wheel are located at the center with the first idle pulley ground floor gear engaged section, and in crankshaft toothed wheel root portion Framing Characters are carved with
