Description
Technical field
The utility model belongs to technical field of engines, and in particular to a kind of Flywheels for engine.
Background technology
In engine system, engine flywheel is the very big disk of a rotary inertia, and it acts as an energy
Memory, rotary inertia is bigger, and energy storage is more.Flywheel is arranged on the ring flange of engine crankshaft rear end, and its main function is exactly
Carry out the storage of energy so that revolution inhomogeneities of the bent axle in operation process is eased.Flywheels for engine is arranged on
Between engine and clutch, a gear ring is pressed with flywheel outer rim, can be engaged with the drive gear of starter, while after it
Face is a composition surface of clutch.Usual flywheel is directly installed on crankshaft of diesel engine rear end by bolt, is transmitted for balancing
Power, and bent axle is turned round in each working cycles uniformly, to ensure cycle irregularity in claimed range.In addition,
Flywheel also ensures the stability of engine open drive, engine is operated steadily, and improves the service life of bent axle.Doing work
In stroke, engine is transferred to the energy of bent axle, and in addition to external output, also portion of energy is absorbed by flywheel, so that bent axle
Rotating speed will not raise a lot, and exhaust, air inlet and compression three strokes in, the energy that flywheel is stored releases compensation
The work(that these three strokes are consumed so that speed of crankshaft will not reduce it is too fast.Make speed of crankshaft and torque output as equal as possible
It is even, prevent from stopping working when engine idling and starting, and make engine that there is the ability for overcoming short-term excess load.
Existing engine flywheel, the end face of flywheel body are connected with engine crankshaft rear end ring flange, other end
Friction plate is installed, friction plate is unfavorable for clutch radiating after being combined with clutch.Clutch radiating is bad, will reduce clutch
The transmission efficiency of device actuating element, it may cause separation not thorough when serious, cause the premature wear of friction plate, can also cause to become
The gearshift of fast device is difficult.
The content of the invention
Technical problem to be solved in the utility model is：A kind of Flywheels for engine is provided, can solve the problem that working condition
The heat dissipation problem of lower clutch.
In order to solve the above technical problems, the technical solution of the utility model is：Flywheels for engine, including：Flywheel body,
The center of the flywheel body offers mounting hole, and connecting hole is offered around the mounting hole, it is characterised in that from
The end face of the flywheel body offers friction plate mounting groove and heat abstractor mounting groove, the radiating dress successively from outside to inside
Put and heat abstractor is installed in mounting groove, the heat abstractor includes the blade installation being arranged in the heat abstractor mounting groove
Axle, and be rotatablely installed in the blade in the blade installation shaft, the blade installation shaft is arranged at heat abstractor mounting groove groove
Bottom, heat emission hole is offered on the heat abstractor mounting groove bottom land.
Further, balance pipe is offered in the flywheel body.
By adopting the above-described technical solution, the beneficial effects of the utility model are：
In flywheel body, friction plate mounting groove and radiating dress are offered successively from outside to inside from the end face of flywheel body
Mounting groove is put, and heat abstractor is installed in heat abstractor mounting groove, heat abstractor includes being arranged on heat abstractor mounting groove
Interior blade installation shaft, and be rotatablely installed in the blade in blade installation shaft, blade installation shaft is arranged at heat abstractor installation
Groove bottom land, and offer heat emission hole in bottom land.Such structure provides heat dissipation channel for clutch, effectively accelerates clutch
The radiating of device, greatly reduce reduction, the separation of the clutch control section transmission efficiency caused by clutch radiating is bad
The generation of the situation such as the not thorough, premature wear of friction plate and shift of transmission difficulty, improves clutch control part
Transmission efficiency and the premature wear for reducing friction plate.
Heat abstractor is rotatablely installed the structure in blade installation shaft using blade, and band movable vane piece turns while flywheel turns
Dynamic, this structure is easy for installation, and cost is relatively low.
