Abstract
The utility model relates to a 2.8 L supercharging diesel engine gear drive system, which solves the problems existing in the current engine that the force requirement of an O IIIBOSCH common rail pump can not be met, namely that the axial force and radial force which is larger than 21N/mm*2 can not be borne, the clockwise rotation of an oil pump can not be met. The specific improvement of the structure is that straight tooth profile modified gears are all adopted, and three transition idle gears are provided, and a foaming material layer is arranged on the inner lateral side of a gear chamber cover to reduce noise. The system not only can meet the force requirement that the O IIIBOSCH common rail pump can not be met, namely that the axial force and radial force which is larger than 21N/mm*2 can not be borne, but also can meet the clockwise rotation requirement of the oil pump. The gear drive is superior to a chain drive and a belt drive, seeing from the space arrangement, difficulty and the reliability of the whole system.
Description
Technical field
The utility model relates to the diesel engine gear train assembly.
Background technique
The diesel engine gear train assembly is the system of transmitting torque in the diesel engine distribution device.Reasonable Arrangement can guarantee higher reliability and accuracy, thereby guarantees the transmitting torque that Diesel Engine Complete Machine is reliable and secure, and cost is low durable.This type of Europe III diesel oil supercharged engine all can adopt train of gearings or belt system, linkwork to come transmission usually.Along with constantly improving and improvement of technology and processing technology, the linkwork transmission is more and more universal, especially in Europe and Japanese market.The train of gearings transmission originally has been in superseded edge in the nineties, but the successful Application of modified gear, and the gear transmission secondary of having got back is popularized.Train of gearings is compared with belt system, has simple, the safe and reliable durable advantage of layout, and low cost and other advantages, and shortcoming is exactly that noise is big.With respect to the linkwork transmission, tool has great advantage on the train of gearings cost because the technology of Domestic market linkwork that is that all right is ripe, mainly still offshore purchase.
Summary of the invention
The purpose of this utility model is: provide and satisfy the altogether force request of rail pump of Europe IIIBOSCH--can not be subjected to axial force and greater than the radial force of 21N/mm^2, and realize a kind of 2.8L supercharged diesel engine gear train assembly that oil pump gear can only clockwise rotate.
Concrete architecture advances scheme is as follows:
A kind of 2.8L supercharged diesel engine gear train assembly comprises crankshaft gear, idle gear, oil pump gear and camshaft gear wheel, also comprises gear chamber cover;
Described crankshaft gear is a straight-tooth gear, the number of teeth 22, and normal module 2.5,20 ° of normal angles, normal direction becomes coefficient 0.4297, standard pitch diameter Φ 55;
Described idle gear comprises idle gear A, idle gear B and idle gear C, is the non-coefficient gear that becomes, the modulus 2.5 of tooth, idle gear A and idle gear B engagement, idle gear B and idle gear C engagement, crankshaft gear and idle gear A engagement;
Described oil pump gear is for becoming the coefficient tooth, the number of teeth 33, normal module 2.5,20 ° of normal angles, oil pump gear and idle gear C engagement;
Described camshaft gear wheel is a straight-tooth gear, the number of teeth 44, and normal module 2.5,20 ° of normal angles, normal direction becomes coefficient 0.0969, standard pitch diameter 110, camshaft gear wheel and idle gear A engagement.
The material of described crankshaft gear, idle gear A, idle gear B, idle gear C, oil pump gear and camshaft gear wheel is the 42CrMo steel.
Rockwell hardness HRC26-32 after described crankshaft gear, idle gear A, idle gear B, idle gear C, oil pump gear and the equal quenching with Subsequent tempering of camshaft gear wheel.
The body of described idle gear A, idle gear B and idle gear C rear side is provided with oil guide plate, and oil guide plate is provided with the oil guide slot of perforation, and three places are arranged on the oil guide slot, and the wheel shaft with idle gear A, idle gear B and idle gear C is corresponding respectively.
Be provided with sponge layer at described gear chamber cover inner side surface.
In order to satisfy the altogether force request of rail pump of Europe IIIBOSCH--can not be subjected to axial force and greater than the radial force of 21N/mm^2, and realize that oil pump gear can only clockwise rotate,, and adopt three idler shaft transition so train of gearings can only be arranged to straight-tooth.Because adopt straight-tooth and three idle pulleys, the noise of this train of gearings is compared with chain transmission system with belt drive system, will be very big, so on the gear chamber cover of this system, increased the noise reduction sponge layer to reduce the noise of complete machine.On the reliability of arrangement space, degree of difficulty and whole system, gear ratio chain-driven, belt transmission are all more excellent.
Description of drawings
Fig. 1 is the utility model gear train assembly assembly layout plan.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1,2.8L supercharged diesel engine gear train assembly comprises crankshaft gear 1, idle gear A2, idle gear B3 and idle gear C4, oil pump gear 5 and camshaft gear wheel 8, also comprises gear chamber cover.
Idle gear A2, idle gear B3 and idle gear C4 are the non-coefficient gear that becomes, the modulus 2.5 of tooth, idle gear A2 and idle gear B3 engagement, idle gear B3 and idle gear C4 engagement, crankshaft gear 1 and idle gear A2 engagement;
Camshaft gear wheel 8 is a straight-tooth gear, the number of teeth 44, and normal module 2.5,20 ° of normal angles, normal direction becomes coefficient 0.0969, standard pitch diameter 110, camshaft gear wheel 8 and idle gear A2 engagement.
The ratio of the crankshaft gear number of teeth and the oil pump gear number of teeth, the camshaft gear wheel number of teeth is 2: 3: 4.
The material of crankshaft gear 1, idle gear A2, idle gear B3, idle gear C4, oil pump gear 5 and camshaft gear wheel 8 is the 42CrMo steel.
