Part or other parts.
As shown in figure 1, specifically including timing gears according to the crankshaft timing gear 2 of the utility model embodiment
Body 21 and the flange 22 for being integrated in this body side surface of the timing gears, timing gears body 21 and flange 22 are formed in one knot
Structure, and offer ladder center positioning hole 23 and circumferential installation bolt hole 24, the positioning hole (aperture) of ladder center positioning hole 23
Positioned with bent axle microcephaly's boss, location fit area is smaller, and difficulty of processing is low, and cost is relatively low；The He of timing gears body 21
Flange 22 passes through circumferential installation bolt hole 24 to be pressed onto crankshaft flange end face by bolt 3, and assembling is simple, and detachable maintaining is simple, drop
Low assembling, maintenance cost.Cylindrical the 25 of flange 22 can also serve as oil sealing sealing face, can adjust length according to arrangement, coordinate with oil sealing
Seal the oil gas that pinion rotation is produced.
Specifically, timing gears body 21 is used to connect by the timing gears of chain and camshaft, so as to ensure gas
It is consistent at the time of the action of door with the state and moment of state and piston movement.
Flange 22 and timing gears body 21 are formed in one structure, and it is integrated in the side of the timing gears body.One
