The transmission ratio of the crankshaft gear to the high-pressure oil pump idle gear is 2:1, the transmission ratio of the crankshaft gear to the high-pressure oil pump gear is 1:1, and the transmission ratio of the crankshaft gear to the blast pump gear is 7:5. The diesel engine timing gear train is stable in transmission and low in noise, and stress distribution of all parts is reasonable.
Description
Technical field
The utility model relates to field of internal combustion engine, is specifically related to the helical gear diesel engine timing of a kind of employing train.
Background technique
What the timing train of general diesel engine adopted is the spur gear transmission, along with people to improving constantly that motor NVH requires, the helical gear transmission is favored by people more and more with its stable drive, advantage that noise is little.And if adopt helical gear words, the energy that adopts which kind of proportioning to utilize bent axle to provide between each gear in the timing train is the problem that the designer need pay close attention to with could realizing steady transmission and optimization substantially.
The model utility content
The purpose of this utility model provides a kind of stable transmission diesel engine timing train.
For achieving the above object, the utility model provides following technological scheme:
A kind of diesel engine timing train comprises: crankshaft gear; The high pressure oil pump idle gear; The high pressure oil pump gear; The inflating pump idle gear; The inflating pump gear; Described crankshaft gear, described high pressure oil pump idle gear, described high pressure oil pump gear and described inflating pump idle gear, described inflating pump gear are helical gear, the velocity ratio of described crankshaft gear and described high pressure oil pump idle gear is 2:1, the velocity ratio of described crankshaft gear and described high pressure oil pump gear is 1:1, and the velocity ratio of described crankshaft gear and described inflating pump gear is 7:5.
Preferably, the modulus of described crankshaft gear, described high pressure oil pump idle gear, described high pressure oil pump gear and described inflating pump idle gear, described inflating pump gear is 2.5, the number of teeth of described crankshaft gear is 30, the number of teeth of described high pressure oil pump idle gear is 60, the number of teeth of described high pressure oil pump gear is 30, the number of teeth of described inflating pump idle gear is 54, and the number of teeth of described inflating pump gear is 42.
The beneficial effects of the utility model are: stable drive, little, the power reasonable mixture ratio of noise.
Description of drawings
Fig. 1 is embodiment's of the present utility model timing train plan view.
Description of symbols among the last figure: crankshaft gear 1, high pressure oil pump idle gear 2, high pressure oil pump gear 3, inflating pump idle gear 4, inflating pump gear 5.
Embodiment
With reference to figure 1, diesel engine timing train of the present utility model comprises crankshaft gear 1, high pressure oil pump idle gear 2, high pressure oil pump gear 3, inflating pump idle gear 4, inflating pump gear 5.And crankshaft gear 1, high pressure oil pump idle gear 2, high pressure oil pump gear 3, inflating pump idle gear 4, inflating pump gear 5 are helical gear, compare with spur gear, and transmission is more steady, and noise is little.In said gear, crankshaft gear 1 is 2:1 with the velocity ratio of high pressure oil pump idle gear 2, and crankshaft gear 1 is 1:1 with the velocity ratio of high pressure oil pump gear 3, and crankshaft gear 1 is 7:5 with the velocity ratio of inflating pump gear 5, and velocity ratio distributes rationally.
In said gear, the modulus of preferably setting crankshaft gear 1, high pressure oil pump idle gear 2, high pressure oil pump gear 3, inflating pump idle gear 4, inflating pump gear 5 is 2.5, the number of teeth of crankshaft gear 1 is 30, the number of teeth of high pressure oil pump idle gear 2 is 60, the number of teeth of high pressure oil pump gear 3 is 30, the number of teeth of inflating pump idle gear 4 is 54, and the number of teeth of inflating pump gear 5 is 42.After adopting above-mentioned parameter, diesel engine timing train can adapt to the force request of the parts that each gear drives well, thereby makes transmission more steady, improves the NVH performance.
Though the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and only be subjected to the restriction of claim, those of ordinary skills can easily make amendment to it and change, but do not leave essence design of the present utility model and scope.
