Description
Technical field
The utility model relates to engine components technical field, especially relates to a kind of flywheel casing.
Background technique
Flywheel casing is one of component of motor, flywheel shell of engine is between body and gearbox, flywheel shell of engine is installed on the outside of engine flywheel and is fixedly connected with gearbox with engine body, and flywheel casing is used for cover cap flywheel by flywheel chamber, plays safety protection function.
Existing flywheel casing poor toughness, fatigue resistance are low, under the state of engine long time service, fixed block between flywheel casing and motor can produce loosening, and then generation high vibration, thus cause between engine gear with flywheel engage bad, affect the normal work of flywheel, even can cause flywheel casing cracking damage.At present, most flywheel casing structure is simple, interface function is single, and needing increases more auxiliary component, can not meet compact structure, modular design concept.
Model utility content
The problem that the utility model solves above-mentioned flywheel casing poor toughness, antifatigue degree is low and structure is simple, interface function is single, provide a kind of flywheel casing, this flywheel casing has good toughness, fatigue resistance is high, flywheel casing end face has radiator window, radiator window installs waterproof cover, can play the function of heat radiation and removal metallic dust, flywheel casing inner sensor mounting hole can sensor installation.
The required technical problem solved of the utility model can be achieved through the following technical solutions:
A kind of flywheel casing, described flywheel casing housing comprises end face and sidewall, described sidewall base has fixing lug boss, bolt fixing hole is uniformly distributed around described boss, described flywheel casing end face has a circular crank shaft oil seal mounting hole, tapped hole installed by the flywheel that distributes around described crank shaft oil seal mounting hole, and described flywheel casing case inside top is provided with sensor mounting hole.
Described flywheel casing is spheroidal graphite cast iron housing.
Described crank shaft oil seal mounting hole is right boring hole.
Described tapped hole is internal thread.
Many stiffening ribs are provided with around described flywheel casing end face crank shaft oil seal mounting hole.
Described flywheel casing housing side has radiator window.
Described radiator window is provided with waterproof cover.
The utility model beneficial effect is: a kind of flywheel casing, adopt ductile cast iron material make flywheel casing has good toughness, fatigue resistance is high, flywheel casing end face has radiator window, radiator window installs waterproof cover, can play the function of heat radiation and removal metallic dust, flywheel casing inner sensor mounting hole can sensor installation.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
