Description
Technical field
The invention belongs to the technology of gasoline engine field, specifically, relate to a kind of flywheel driving disc from the tape starting cup.
Background technique
Petrol engine is generally the cast iron single piece with the flywheel driving disc, has an outer shroud and a curved end, is provided with groove on the outer peripheral surface of driving disc outer shroud, for magnet steel is installed; The central authorities of driving disc end face have the taper axis hole, and the hole wall of axis hole extends towards the direction of outer shroud, forms axle sleeve.The driving disc of this cast iron structure exists machining allowance big, weak heat-dissipating, and manufacturing efficiency is low, and deficiencies such as processing pollution environment if load onto magnet steel and starting cup, are formed flywheel, and burst apart easily in the position of driving disc strength weak, flywheel is scrapped; And Heavy Weight, the inertia of flywheel are big, and period of braking needs 4～5 seconds, if be used for the lawn machine, and the related request that must in 3 seconds, stop when not satisfying the flywheel braking.Be weight reduction, the flywheel that has adopts aluminum alloy with integral casting formings such as driving disc, starting cups, but cost of material height, the intensity of aluminum alloy flywheel are low, and its key position is easy to wear, also has not long problem in working life.
Summary of the invention
Technical problem to be solved by this invention is to provide the flywheel driving disc from the tape starting cup that a kind of cost is low, intensity is secure, to alleviate the weight of flywheel, shortens period of braking.
Technological scheme of the present invention is as follows: a kind of flywheel driving disc from the tape starting cup, this driving disc have an outer shroud and a driving disc end face by the steel plate punching stretch forming, are provided with the ccontaining position of installing for magnet steel on the driving disc outer shroud; The central authorities of described driving disc end face have axis hole, this driving disc end face is towards the direction punching press flange opposite with outer shroud, form at least 2 starting teeth, each starts tooth and evenly distributes on same circumference or regular polygon, constitute the starting cup, and shaft axis that should the starting cup overlaps with the shaft axis of described axis hole.
The present invention is according to the needs of different type of machines, choose the steel plate of desired thickness, by punching press, stretching, formation has outer shroud and end face and has the driving disc of starting cup, compare with the cast iron structure of background technique, its weight saving about 1/3, inertia is corresponding to be reduced greatly, make the flywheel that becomes by component-assembled such as this driving disc and magnet steel when braking, just can stop operating fully in 3 seconds, satisfied the related request of lawn machine.Because it is raw material that driving disc adopts steel plate, intensity strengthens greatly than cast iron or aluminium alloy structure, and driving disc is not easy to wear, thereby has effectively prolonged the working life of flywheel.Driving disc has replaced the function of split type starting cup in the background technique from the tape starting cup, and so not only processing is more prone to, and has saved lot of materials, greatly reduces manufacture cost.
As improvement, above-mentioned driving disc end face forms 3～12 arc starting teeth towards the direction punching press flange opposite with outer shroud, and each starts tooth and evenly distribute formation starting cup on same circumference.
Improve as another kind, above-mentioned driving disc end face forms 3～12 starting teeth towards the direction punching press flange opposite with outer shroud, and each starts tooth and evenly distribute formation starting cup on same regular polygon.
No matter the starting tooth still evenly distributes on regular polygon in even distribution on the circumference, it is stressed even when starting all to guarantee respectively to start tooth, has so both ensured starting effect, has effectively prevented the distortion and the bending that take place because of unbalance stress again.
For the ease of punching press, and reach better starting effect, above-mentioned starting tooth is rectangular sheet structure, and perpendicular to the driving disc end face, has spacing between the two adjacent starting teeth.
For further strengthening the rigidity of starting cup, lug is extended to both sides in the outer end of above-mentioned starting tooth, and the starting tooth is "T"-shaped, face contact between two lugs of inboard on the two adjacent starting teeth.
Above-mentioned ccontaining position of installing for magnet steel is the groove that forms towards its central direction punching press on the driving disc outer shroud, and the bottom surface of this groove has the installation screw.When magnet steel was installed, magnet steel was positioned at groove, by screw.Groove can be according to the shape impact briquetting of magnet steel, and it is simple in structure, and the conformity of shape, size is better, and the shape that every punching press can form, size all can realize.
Above-mentioned ccontaining position of installing for magnet steel is the breach of being opened on the driving disc outer shroud.When magnet steel is installed, fix a support in the inboard of breach, magnet steel is installed on this support, is compressed by pressing plate, and the shape and the breach of pressing plate adapt, and fixes by screw and magnet steel and support.Some shape, the special magnet steel of size can be installed so quickly and easily, satisfy different needs.
The hole wall of above-mentioned driving disc end face upper shaft hole extends towards the direction of outer shroud, forms axle sleeve.Axle sleeve and driving disc are structure as a whole, and not only processing is simpler, and cost is lower.
1, it can replace cast iron or aluminum alloy driving disc and starting cup structure, is used for small utility gasoline engine, and using scope is extensive.
2, driving disc is raw material with the steel plate, makes the weight of whole flywheel lighter, and inertia is less, just can stop operating fully in 3 seconds when braking, has satisfied the related request that is used for the lawn machine.
3, steel structure is than cast iron and aluminium alloy structure, and intensity and wear resistance are better, and prolong the working life of driving disc greatly.
4, the processing technology of driving disc is simple, and the manufacturing efficiency height effectively reduces manufacture cost.
5, driving disc is from the tape starting cup, its easy processing, and saved a large amount of raw material, further reduced the manufacture cost of flywheel.Compare with the cast iron structure, its cost has reduced about 35%; Compare with aluminium alloy structure, its cost reduction reaches 60%.
