Kodi chingwe chosasunthika n'chiyani?

Zingwe zosasunthika zimagawidwa m'zingwe zamtundu wa A ndi zingwe zamtundu wa B:

Chingwe cha Mtundu A: chimagwiritsidwa ntchito poika m'mapanga, kupulumutsa, ndi malo ogwirira ntchito pogwiritsa ntchito zingwe. Posachedwapa, chagwiritsidwa ntchito polumikizana ndi zida zina kuti chichoke kapena chipite ku malo ena ogwirira ntchito mukakhala ndi vuto kapena loyimitsidwa.
Chingwe cha Mtundu B: chimagwiritsidwa ntchito limodzi ndi chingwe cha Gulu A ngati chitetezo chowonjezera. Chiyenera kusungidwa kutali ndi mikwingwirima, mabala, ndi kuwonongeka kwachilengedwe kuti muchepetse mwayi wogwa.

Zingwe zosasunthika zimagwiritsidwa ntchito nthawi zambiri pofufuza ndi kupulumutsa anthu m'mapanga, koma nthawi zambiri zimagwiritsidwa ntchito m'malo okwera kwambiri, ndipo zingagwiritsidwenso ntchito ngati chitetezo cha zingwe zapamwamba m'malo ochitira masewera olimbitsa thupi okwera miyala; zingwe zosasunthika zimapangidwa kuti zikhale ndi kusinthasintha kochepa momwe zingathere, kotero sizingayamwe kugwedezeka.

Chingwe chosasunthika chili ngati chingwe chachitsulo, chomwe chimatumiza mphamvu yonse yokhudza kugwedezeka mwachindunji ku chitetezo ndi munthu amene wagwa. Pankhaniyi, ngakhale kugwa kochepa kudzakhala ndi mphamvu yaikulu pa dongosololi. Mu ntchito monga chingwe chokhazikika, malo ake okokera amakhala pakhoma lalikulu, phiri kapena phanga. Chingwe chomwe chimakhala ndi kuchepa pang'ono chimatchedwa chingwe chosasunthika, ndipo chidzatalikitsidwa ndi pafupifupi 2% malinga ndi kulemera kwa thupi. Pofuna kuteteza chingwecho ku kuwonongeka kwambiri, chingwecho nthawi zambiri chimapangidwa kukhala chokhuthala ndipo chimawonjezeredwa chipolopolo choteteza. Zingwe zosasunthika nthawi zambiri zimakhala pakati pa 9mm ndi 11mm m'mimba mwake, kotero nthawi zambiri zimakhala zoyenera kukwera, kutsika, komanso kugwiritsa ntchito ma pulley. Zingwe zopyapyala ndiye chisankho chabwino kwambiri pakukwera m'mapiri chifukwa nkhawa yayikulu pakukwera m'mapiri ndi kulemera. Ogwira ntchito ena amagwiritsa ntchito chingwe chopangidwa ndi polypropylene yosasunthika ngati chingwe chokhazikika. Chingwe chamtunduwu ndi chopepuka komanso chotsika mtengo, koma chingwe chamtunduwu sichingagwiritsidwe ntchito, ndipo chimakhala ndi mavuto. Chingwe chosasunthika chiyenera kukhala ndi mtundu waukulu wa 80%, ndipo chingwe chonsecho sichiyenera kupitirira mitundu iwiri yachiwiri.
