Fig. 2 is cluster gear and fuel injection pump gear and other idle pulley syntagmatic schematic diagrames.
Specific embodiment
Structure of the present utility model is described further below in conjunction with accompanying drawing and by embodiment, but the utility model
The content for being covered is not limited to following embodiments.
The timing gear train of oil pump and compression pump is driven, its composition structure is：Timing gear train is provided with four idle pulleys, 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；First idle pulley
Second layer gear 2-2 is engaged with fuel injection pump gear 3；The third layer gear 2-3 of the first idle pulley is nibbled with the lower-left end of the second idle pulley 4
Close.Engaged 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.Crankshaft toothed wheel
Left end 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 and pump tooth of calming the anger of the 4th idle pulley
Wheel 9 is engaged.Crankshaft toothed wheel is operated 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 Framing Characters are carved with crankshaft toothed wheel root portion
L；It is carved with two significant alphabetical AA in the first idle pulley ground floor gear position corresponding with crankshaft toothed wheel.Cam shaft gear is just
When mark be located at center with the 3rd idle pulley engaged section, be carved with significant letter b in the root portion of cam shaft gear.
