Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Shown in Fig. 1～6, motorcycle engine described in the utility model comprises the crankcase of being made up of left and right crankcases, camshaft is threaded onto in the camshaft hole on the crankcase, right crankcase top is provided with oilhole A2, the left side of oilhole A2 is separation layer B4, and the right side of oilhole A2 is followed successively by separation layer A3, separation layer C5; Left crankcase top is provided with the separation layer D7 adaptive with oilhole A2, separation layer E8; The casing paper washer top of left crankcase is provided with the oil through 12 adaptive with oilhole A2; The junction plane place of left crankcase top and cylinder is provided with oil duct 10, and oil duct 10 left ends are provided with oilhole C11, and right-hand member is provided with oilhole B9; The cylinder paper washer of cylinder is provided with the seal point 15 adaptive with oil duct 10; The outer surface of camshaft right-hand member is provided with an annular oil groove 19, the right side of annular oil groove 19 is provided with end cover 18, laterally zygomorphic oilhole D16 and the oilhole E17 that connects camshaft that be provided with in the annular oil groove 19, camshaft left end and annular oil groove 19 evenly are laid with oilhole G21 and oilhole F20.
As mentioned above, the main points of the scheme that the utility model is taked are: the right segment of camshaft bottom is carried out totally-enclosed with end cover 18, belt oil groove 19 of right segment axial plane design, two oilholes of design---oilhole D16 and oilhole E17 feed camshaft inside in the annular oil groove 19.The utility model makes lubricant oil can have sufficient oil pressure that camshaft and cam sleeve are lubricated by camshaft oil gallery is set, and it is lubricated to change splash lubrication into oil duct.
The utility model has the advantages that has increased the design of camshaft for motorcycle engine oil circuit, motorcycle engine CG150/125 is a post rod type underlying cam structure, cam and camshaft are in left crankcase, right crankcase and cylinder triplicity position, must be because enter the machine oil of camshaft oil gallery through the position of triplicity, so the cylinder paper washer on left crankcase, right crankcase and casing paper washer, the cylinder junction plane has been done corresponding change, this part is auxiliary newly-increased structure.See the structural representation of Fig. 1 right crankcase, oilhole A, separation layer A, separation layer B, separation layer C are newly-increased structure.See the structural representation of Fig. 2 left crankcase, separation layer D, separation layer E are newly-increased structure.See the structural representation of Fig. 3 left crankcase top junction plane, oilhole B, oil duct, oilhole C are newly-increased structure.See the structural representation of Fig. 4 casing paper washer, oil through is newly-increased structure.See the structural representation of Fig. 5 cylinder paper washer, seal point is newly-increased structure.Auxiliary newly-increased structure role is to be combined into a complete sealing oil circuit to arrive camshaft and do not influence other performances of motor by machine oil.Oil lubrication is successively behind oil-through hole A (2), oil through (12), oilhole C (11), oil duct (10), oilhole B (9), annular oil groove (19), oilhole D (16) and oilhole E17, flow into camshaft and camshaft axle sleeve place, flow between camshaft and the cam sleeve from oilhole F (20) and oilhole G (21) again.Form the effective oil film of one deck on camshaft surface, the vibration force of sending when buffering alleviates cam work, the noise at cam position when having reduced engine operation has prolonged motor working life.
