Kodi ulusi wa screw ungatchulidwe bwanji kuti ulusi wosalala? Tiyeni tiwufotokoze motere: ulusi wosalala ukhoza kutanthauzidwa ngati ulusi wamba; Ulusi wosalala, kumbali ina, umagwirizana ndi ulusi wosalala. Pansi pa mainchesi ofanana, chiwerengero cha mano pa inchi iliyonse chimasiyana, zomwe zikutanthauza kuti phula ndi losiyana. Ulusi wosalala uli ndi phula lalikulu, pomwe ulusi wosalala uli ndi phula laling'ono. Ulusi wosalala kwenikweni umatanthauza ulusi wamba. Popanda malangizo apadera, zomangira zachitsulo chosapanga dzimbiri ndi zomangira zina zomwe nthawi zambiri timagula ndi ulusi wosalala.
Makhalidwe a zomangira za ulusi wopyapyala ndi amphamvu kwambiri, kusinthasintha bwino, komanso miyezo yofanana. Kawirikawiri, ulusi wopyapyala uyenera kukhala chisankho chabwino kwambiri; Poyerekeza ndi ulusi wopyapyala wopyapyala, chifukwa cha ngodya yayikulu ya pitch ndi ulusi, magwiridwe antchito odzitsekera okha ndi otsika. M'malo ogwedezeka, ndikofunikira kukhazikitsa mawaya otsekera, zida zodzitsekera zokha, ndi zina zotero; Ubwino wake ndi wakuti n'zosavuta kusokoneza ndi kusonkhanitsa, ndipo zigawo zokhazikika zomwe zimabwera nazo zimakhala zathunthu komanso zosavuta kusinthana; Mukalemba ulusi wopyapyala, palibe chifukwa cholemba pitch, monga M8, M12-6H, M16-7H, ndi zina zotero, zomwe zimagwiritsidwa ntchito makamaka polumikiza ulusi.
Mano osalala ndi mano osalala ndi osiyana kwambiri, ndipo amafotokozedwa kuti awonjezere zofunikira zapadera zomwe mano osalala sangakwaniritse. Ulusi wa mano osalala ulinso ndi mzere wozungulira, ndipo utoto wa mano osalala ndi wocheperako. Chifukwa chake, mawonekedwe ake ndi abwino kwambiri kuti azidzitsekera okha, oletsa kumasuka, komanso mano ambiri, zomwe zimachepetsa kutuluka kwa madzi ndikupangitsa kuti mano azitseke. Mu ntchito zina zolondola, zomangira zachitsulo zosapanga dzimbiri zokhala ndi mano osalala zimakhala zosavuta kuziwongolera ndikusintha molondola.
Choyipa chake ndi chakuti mphamvu ndi mphamvu zake zimakhala zochepa poyerekeza ndi mano okhwima, ndipo ulusiwo umawonongeka mosavuta. Sikoyenera kusokoneza ndi kusonkhanitsa kangapo. Ma mtedza ndi zomangira zina zomwe zikugwirizana nazo zitha kukhala zolondola mofanana, ndi zolakwika zazing'ono za kukula, zomwe zingayambitse kuwonongeka kwa zomangira ndi mtedza nthawi imodzi. Ulusi wopyapyala umagwiritsidwa ntchito makamaka mu zomangira mapaipi a metric mu machitidwe a hydraulic, magawo otumizira makina, magawo owonda okhala ndi makoma ochepa omwe alibe mphamvu zokwanira, magawo amkati omwe ali ndi malo ochepa, ndi ma shafts omwe ali ndi zofunikira zambiri zodzitsekera. Polemba ulusi wopyapyala, pitch iyenera kulembedwa kuti iwonetse kusiyana ndi ulusi wokhwima.
Zomangira zopyapyala komanso zazing'ono zimagwiritsidwa ntchito pomangirira.
Zomangira zokhala ndi mano opyapyala nthawi zambiri zimagwiritsidwa ntchito kutseka ziwalo ndi ziwalo zokhala ndi makoma owonda zomwe zimafunikira kwambiri kuti zisagwedezeke. Ulusi wopyapyala umadzigwira bwino ntchito, motero uli ndi mphamvu yolimbana ndi kugwedezeka komanso kumasula. Komabe, chifukwa cha kuya kochepa kwa mano a ulusi, kuthekera kopirira mphamvu yolimba yogwira ntchito kumakhala koipa kuposa ulusi wolimba.
Ngati palibe njira zoletsera kumasula zomwe zatengedwa, mphamvu yoletsera kumasula ya ulusi wosalala imakhala yabwino kuposa ya ulusi wokhotakhota, ndipo nthawi zambiri imagwiritsidwa ntchito pazigawo zopyapyala komanso zigawo zomwe zimafunikira kwambiri kuti zisagwedezeke.
Zokulungira ulusi wopyapyala zimakhala ndi ubwino wambiri pokonza zinthu. Vuto la ulusi wopyapyala ndilakuti siliyenera kugwiritsidwa ntchito pazinthu zokhala ndi minofu yokhuthala kwambiri komanso zolimba. Mphamvu yomangira ikakwera kwambiri, zimakhala zosavuta kutsetsereka ulusiwo.
