On wheel shaft, oil pump gear is arranged on machine oil pump shaft, and right balance shaft idle gear is put down installed in the right side for being fixed on body front end face
Weigh on axle idle gear shaft, for air compressor machine gear set in air compressor machine drive shaft, fuel injection pump gear 7 is sleeved on injection pump drive shaft
On, right balance shaft gear be arranged on right balance shaft on, left balance shaft gear be arranged on left balance shaft on, hydraulic pump driving gear and
Hydraulic pump driving spline housing is installed togather, and is sleeved on by hydraulic pump driving spline housing in hydraulic pump driveshaft.
Crankshaft toothed wheel engages with idle gear, and idle gear engages with cam shaft gear, oil pump gear, fuel injection pump gear, right
Balance shaft idle gear engages with cam shaft gear, hydraulic pump driving gear, right balance shaft gear, oil pump gear and left balance shaft
Gear, idle gear engagement, air compressor machine gear engage with cam shaft gear.
The utility model can reach following beneficial effect after using above-mentioned technical proposal：3 moduluses and 4 moduluses flower can be chosen to install
The timing gear of diesel engine system gearratio of key hydraulic pump is accurate, reliability is high, switching is simple, can realize efficient driving.Pass through
Only change hydraulic pump driving spline housing, you can realize the switching installation of 3 moduluses and 4 modulus spline hydraulic pumps, while need not change
Become the other parts of timing gear train, each gear centre coordinate position is constant, so as to realize that gear chamber, body main parts size are led to
With effectively reducing manufacturing cost.
