Description
Technical field
The utility model relates to a kind of single cylinder diesel six gear trains, belongs to the single cylinder diesel technical field.
Background technique
The six gear trains that single cylinder diesel adopts, its structure can satisfy the needs of existing single cylinder diesel substantially, but along with power, the discharge capacity of single cylinder diesel continues to increase, under existing technical conditions, improving the power of single cylinder diesel, mainly is exactly to strengthen discharge capacity, and the main employing at present of increasing discharge capacity has two, the one, strengthen cylinder diameter, the 2nd, strengthen stroke.Now adopt present structure stroke maximum can only arrive 120 millimeters, can only expand cylinder, can cause problems such as volume increase so again and strengthen discharge capacity.In addition, six gear trains of structure also exist the gear wear inequality at present, problems such as speed governing, startup difficulty.
The model utility content
Problem at above-mentioned existence, the purpose of this utility model is to provide a kind of single cylinder diesel six gear trains, under the situation of size that does not change existing cylinder body and structure, the stroke of diesel engine can reach 135 millimeters, thereby under the condition that the diesel engine cylinder diameter equates, the diesel engine discharge capacity can improve 12.5%.
For achieving the above object, a kind of single cylinder diesel six gear trains of the utility model comprise: crankshaft timing gear, last balance shaft gear, starting gear, idle gear, camshaft gear wheel and following balance shaft gear, the number of teeth of crankshaft timing gear is 22, the number of teeth of last balance shaft gear is 22, the number of teeth of balance shaft gear is 22 down, the number of teeth of starting gear is 42, the number of teeth of camshaft gear wheel is 44, and the number of teeth of idle gear is 44; The level of described crankshaft timing gear and idle gear, perpendicular distance are respectively 37.1mm, 91.79mm, the level of described crankshaft timing gear and camshaft gear wheel, perpendicular distance are respectively 94.19mm, 105.44mm, the level of described crankshaft timing gear and last balance shaft gear, perpendicular distance are respectively 135.8mm, 99.5mm, the level of described crankshaft timing gear and starting gear, perpendicular distance are respectively 123.13mm, 4.34mm, and described crankshaft timing gear is respectively 135.8mm, 99.5mm with level, the perpendicular distance of following balance shaft gear.
Compared with the prior art the utility model has the following advantages:
1, by to design and the improvement of each tooth numbers of teeth of six gear trains, Gear center apart from distance, solved the bottleneck problem of big discharge capacity six gear train single cylinder diesel spatial arrangement, thereby had simply compactness of complete machine, each gear wear is even, speed governing is flexible, starts reliable advantage;
2, stroke of the present utility model can reach 135 millimeters, thereby under the condition that the diesel engine cylinder diameter equates, the diesel engine discharge capacity can improve 12.5%;
3, keep the size and the structure of existing cylinder body constant, therefore can continue to use parts such as existing cylinder body, thereby save manufacture cost greatly;
4, layout is more reasonable, thereby has also reduced the vibrations of cylinder body greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further details.
Fig. 1 is a structural representation of the present utility model.
