Description
Technical field
The utility model relates to the rearmounted train of gearings of a kind of Novel diesel engine.
Background technique
The supporting facilities such as air compressor, oil hydraulic pump, Injection Pump that are provided with on diesel engine, its power resources all come from bent axle, crankshaft timing gear and bent axle gearwheel are installed on bent axle, camshaft gear wheel is installed on camshaft, intermediate gear shaft is also housed on diesel-engine body, and the gear of above-mentioned facility engages and carries out power transmission with crankshaft timing gear, bent axle gearwheel or camshaft gear wheel respectively.The diesel engine gear chamber space of existing same discharge capacity is less, for power taking output after meeting, convenient layout, at diesel engine front end, train of gearings is set, and export in rear end cloth postpone power taking separately, but the front end torsional oscillation of crankshaft of diesel engine is larger, at diesel engine front end, gear transmission linkage structure is set and easily causes diesel vibration excessive, and the stability of transmission and reliability reduction.
Model utility content
The utility model provides a kind of rearmounted train of gearings of Novel diesel engine that thereby intermediate transmission structure is integrated into diesel engine rear portion and reduces diesel vibration for the problems referred to above.
In order to solve the problems of the technologies described above, the utility model provides a kind of Novel diesel engine of following structure rearmounted train of gearings, it comprises crankshaft timing gear and the bent axle gearwheel at the bent axle rear portion being connected on diesel-engine body, the camshaft gearwheel that is arranged on camshaft rear portion and engage with crankshaft timing gear and the gear broad in the middle that is connected to intermediate gear shaft rear portion and engages with bent axle gearwheel, diesel-engine body rear portion is connected with hydraulic pump gear, fuel injection pump gear and air compressor gear, its structural feature is: the intermediate speed pinion for engaging with air compressor gear is housed on described intermediate gear shaft, rear power taking axle is housed on the flywheel casing on diesel-engine body, the rear power take-off gear engaging with gear upper driving broad in the middle is housed on rear power taking axle, described camshaft gearwheel engages with hydraulic pump gear, camshaft gearwheel is also fitted with camshaft small gear, described fuel injection pump gear engages with camshaft small gear.
The corresponding spiral mounting hole and by being installed on the clamping bolt matched together in spiral mounting hole of being periphery on described camshaft gearwheel and camshaft small gear.
The utlity model has following advantage: hydraulic pump gear, fuel injection pump gear and air compressor gear are all integrated into diesel engine rear portion, the double driving of crankshaft gear, make structure compacter, reduce machine volume, train of gearings postposition, arrange and reserve sufficient space for frontal attachments, and greatly reduce the vibration of diesel engine; Be realize after intermediate gear drives power taking and drive air compressor, oil pump, oil hydraulic pump by said gear, realized many power output, ensure stability and the reliability of transmission.
In sum, the utlity model has vibration and the guarantee stability of transmission and the advantage of reliability that structure is compacter, reduce machine volume, reduction diesel engine.
