Mfundo yoyendetsera njira imodzi

 

Chotengera cholowera mbali imodzindi mtundu wa bearing womwe umazungulira momasuka mbali imodzi ndikutseka mbali inayo. Chipinda chachitsulo cha bearing ya njira imodzi chimakhala ndi ma roller ambiri, ma needle roller kapena mipira, ndipo mawonekedwe a mpando wozungulira (dzenje) amachititsa kuti uzungulire mbali imodzi yokha, ndipo umapanga kukana kwakukulu mbali inayo (yomwe imatchedwa "njira imodzi").

Mfundo yogwirira ntchito ya mabearing a njira imodzi

1. Kapangidwe ka ramp ndi roller

Ma clutch amtundu wa ramp ndi roller okhala ndi njira imodzi amakhala ndi mphete yakunja yokhala ndi m'mimba mwake wamkati wa mbiya, mphete yamkati yokhala ndi ramp, ndi gulu la ma rollers omwe amakhudzidwa ndi mphamvu za masika ndipo nthawi zonse amakhala pafupi ndi mphete zamkati ndi zakunja. Bola ngati kuzungulira kwa msewu umodzi wopita komwe ukuyenda kumakhudza winayo, dongosololi limatsimikizira kuti liwiro lidutsa komanso kuthekera koyendetsa nthawi yomweyo.

Kugwiritsa ntchito mtundu uwu wa clutch wolunjika kungakhale koyenera kugwiritsa ntchito mopitirira muyeso, motsatira indexing komanso mosasintha m'malo osiyanasiyana.

Ikagwiritsidwa ntchito ngati chogwirira chapadera cha njira imodzi

Chogwirira cha ramp-type chozungulira chimodzi chidzayikidwa motere, mwachitsanzo mphete yakunja idzagwiritsidwa ntchito ngati chogwirira ntchito. Izi ndizofunikira kwambiri podutsa liwiro lalikulu. Pankhani ya inner ring overcake, mphamvu ya centrifugal yomwe imagwira ntchito pa ma rollers idzachepetsa liwiro la overcake.

Ikagwiritsidwa ntchito ngati cholumikizira chosinthira mbali imodzi

Clutch ya ramp roller yokhala ndi ring rotation yamkati yokha ndiyo yoyenera kuthamanga pang'ono. Ngati pakufunika liwiro lalikulu, clutch ya wedge-type imodzi imalimbikitsidwa.

Ikagwiritsidwa ntchito ngati cholumikizira cha njira imodzi

Mphete yakunja nthawi zambiri imawonedwa ngati chinthu chozungulira, ndipo mphete yamkati nthawi zambiri imawonedwa ngati chinthu chogwirira ntchito. Kupanda kutero, kusakhala ndi mphamvu kwa ma rollers ndi ma spring kudzabweretsa zolakwika, makamaka pa high frequency indexing. Kugwiritsa ntchito mafuta odzola ochepetsedwa ndi ma spring amphamvu kumapereka kulondola kwa high speed indexing komanso khalidwe labwino.

2. Kapangidwe ka wedge

Cholumikizira chowongolera cha mtundu umodzi nthawi zambiri chimakhala ndi mphete yamkati, mphete yakunja, gulu la wedge, khola la wedge, kasupe wolimba ndi chogwirira. Wedge imalumikizidwa pakati pa mphete zamkati ndi zakunja kuti isamutse mphamvu kuchokera pa raceway imodzi kupita ku ina. Wedge ili ndi mainchesi awiri opingasa, (monga mtunda kuchokera pakona imodzi ya wedge kupita ku ina) ndipo imodzi mwa izo ndi yayikulu kuposa inayo. Kuchita kwa wedge kumachitika pamene mphete zamkati ndi zakunja zimazungulirana, zomwe zimapangitsa wedge kukhala ndi malo akulu oyima pagawo lalikulu.

3. Mphamvu ya wedge yodzitsekera yokha imadalira kwambiri wedge ndi ngodya yodzitsekera yokha ya wedge pakati pa mphete zamkati ndi zakunja. Lingaliro loyambira la wedge one-way clutch limafuna kuti coefficient of friction ya wedge igwirizane ndi torque yadzidzidzi yopangidwa ndi mphete yamkati molunjika ku drive, ndipo mtengo wa friction uwu uyenera kukhala wokulirapo kuposa mtengo wa tangent wa angle yodzitsekera yokha. Ngati mikhalidweyo ndi yosatetezeka, wedge sidzachitika.

Ngodya yodzitsekera yokha imatsimikiziridwa ndi kapangidwe ka wedge, ndipo mfundo zomwe zili pa mphete zamkati ndi zakunja zimalumikizidwa ndi wedge motsatana.

Kapangidwe ka wedge kali ndi ngodya yodzitsekera yokha yotsika kwambiri kuti zitsimikizire kuti ikugwirizana bwino poyamba. Pamene torque ikukwera, mphamvu yozungulira imapangidwa pa wedge yomwe imapatutsa msewu wa wedge, zomwe zimapangitsa kuti wedge izungulire kupita pamalo atsopano. Wedge nthawi zambiri imapangidwa kuti ikhale ndi ngodya yodzitsekera yokha yomwe ingawonjezedwe pang'onopang'ono, monga momwe imayendera kuchokera pamalo opitilira mpaka pamalo pomwe katundu wambiri amanyamula. Ngodya yodzitsekera yokha yayikulu imachepetsa mphamvu yozungulira yopangidwa ndi wedge, kotero kuti ma torque akuluakulu amaloledwa kutumizidwa bola ngati malire a kutalika ndi kuuma kwa Brinell akufunika.

Kugwiritsa ntchito kwakukulu kwa mabearing a njira imodzi: makina opangidwa ndi nsalu; makina osindikizira; makampani opanga magalimoto; Zipangizo zapakhomo; chowunikira zinthu zabodza.
