Abstract
The utility model discloses a novel diesel engine flywheel case, which comprises a casing, wherein a communicated crank shaft oil seal installing hole is formed in the center on the front end surface of the casing, a screw bolt fixing lug boss with a screw bolt hole is arranged around the crank shaft oil seal installing hole, the casing is fixed on a machine body through the screw bolt fixing lug boss, the right side of the crank shaft oil seal installing hole is provided with a starting machine installing hole, a communicated screw bolt position avoiding hole is formed in a position above the right side of the crank shaft oil seal installing hole, and a plurality of reinforcing ribs are respectively arranged on the front end surface and the back end surface of the casing. Compared with the prior art, the novel diesel engine flywheel case has the following advantages that the structure layout is compact, the size is small, and the cost is low. In addition, the novel diesel engine flywheel case is made of ductile cast iron materials, the toughness is good, and the tensile strength is high. In addition, the reinforcing ribs are respectively arranged on the front end surface and the back end surface of the flywheel case, the intensity of the flywheel case is enhanced, meanwhile, the weight is reduced, and the materials are saved.
Description
Technical field
The utility model relates to engine components, in particular a kind of Novel diesel engine flywheel casing.
Background technique
Existing flywheel shell of diesel engine, poor toughness, fatigue resistance is low, starting under the state worked long hours, fixed block between flywheel casing and starter motor can produce loosening, and then produces serious vibration, thereby causes meshing between starter gear and flywheel bad, the normal operation of influence power flywheel, even can cause the flywheel casing cracking to damage.In addition, the most topology layout of flywheel shell of diesel engine is complicated to be disperseed, compact not, has increased cost.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of good toughness, intensity are high, the Novel diesel engine flywheel casing of compact structure.
The utility model is achieved through the following technical solutions:
The Novel diesel engine flywheel casing, comprise housing, on described housing front-end face, central authorities are provided with the crank shaft oil seal mounting hole of perforation, be provided with around described crank shaft oil seal mounting hole the strap bolt hole the bolt fixing lug boss, described housing is fixed on body by described bolt fixing lug boss, the right-hand starter motor mounting hole that is provided with of described crank shaft oil seal mounting hole, described crank shaft oil seal mounting hole upper right is provided with the bolt resigning hole of perforation, is equipped with many stiffening ribs on described housing front-end face and ear end face.
Described bolt resigning hole is three, and described three bolt resigning holes are arranged along even circumferential.
Described crank shaft oil seal mounting hole bottom is that rectangle, top are for semicircle.
The front-end face of described crank shaft oil seal mounting hole and described housing and ear end face junction are equipped with annular boss.
Described one week of housing is provided with a plurality of mounting holes.
Described housing is the spheroidal graphite cast iron housing.
The utility model has the following advantages compared to existing technology:
The Novel diesel engine flywheel casing that the utility model provides, the topology layout compactness, volume is little, and cost is low.And it adopts ductile cast iron material to make, good toughness, tensile strength are high.In addition, be equipped with stiffening rib on flywheel casing front-end face and ear end face, when increasing flywheel casing intensity, alleviated weight, saved material.
