Maboti a mapewandi mtundu wa ulusi womangirira chinthu chodziwika ndi mutu, gawo lopanda ulusi lotchedwa phewa, ndi gawo la ulusi lomwe limalumikizana ndi ziwalo zokwerera mpaka pamapewa. Phewa limakhalabe likuwonekera pamwamba pa zinthu zokwerera pamene gawo la ulusi lili m'malo, limapereka malo osalala, ozungulira kuti zigawo zina zizizungulira, kuzungulira, kapena kugwirizanitsa.
Ngakhale pali zosankha zosiyanasiyana, ma bolts amagawana zinthu zitatu zofunika:
Mutu (nthawi zambiri mutu wa kapu, koma njira zina monga mitu yathyathyathya kapena hex)
Mapewa owoneka bwino mkati mwa kulolerana kolimba
Gawo la ulusi (lopangidwa kuti likhale lolondola; nthawi zambiri UNC / ulusi wolimba, ngakhale ulusi wa UNF ulinso mwayi)
Makhalidwe a steppe screws
Zomangira zapamapewa zimakhala ndi mapangidwe osiyanasiyana amitundu yosiyanasiyana yogwiritsira ntchito.
Kusintha kwa Mutu
Maboti awa amabwera ndi mutu wopindika, womwe umakhala ndi mitsinje yowongoka yopitilira kutalika kwake, kapena mutu wosalala. Mutu wopindika umachepetsa mwayi wolimbitsa kwambiri ndipo umapereka mphamvu yogwira, pomwe mutu wosalala umasankhidwa kuti ukhale wowoneka bwino.
Mutu Shape
Kukonzekera kwa mutu wa bolt kumakhudza zonse zomwe zimapangidwira komanso kuyika komaliza motsutsana ndi malo okwera. Ngakhale mitu yamutu imakhala yofala pakati pa mabawuti am'mapewa, masitayelo ena ammutu monga mitu ya hexagonal ndi yosalala amapezekanso. Kwa mapulogalamu omwe amafunidwa pang'ono, zosankha zamutu zotsika komanso zotsika kwambiri zimaperekedwa.
Mtundu wa Drive
Bolt's drive system imatchula mtundu wa chida chofunikira pakuyika komanso kukhazikika kwa kuluma kwake pamutu. Makina oyendetsa omwe amapezeka kwambiri amaphatikiza mapangidwe amutu a socket, monga hex ndi sockets zisanu ndi chimodzi. Machitidwewa amalimbikitsa kumangirira kolimba ndi mwayi wochepa wa kuwonongeka kwa mutu kapena kutaya mphamvu. Kuphatikiza apo, ma drive a slotted amagwiritsidwanso ntchito kwambiri ndipo amagwirizana ndi zida zosiyanasiyana zoyikira, zomwe zimapatsa kusinthasintha pakugwiritsa ntchito kwawo.
Kodi mawonekedwe a Shoulder screw threads ndi chiyani?
Ulusi Wowonjezera: Izi zili ndi ulusi wautali woposa muyezo, zomwe zimapatsa mphamvu yogwira komanso yokhazikika.
Ulusi Wokulirapo: Ngakhale ulusi wamba wa mapewa ndi wopapatiza kuposa m'lifupi mwake, ulusi wokulirapo umafanana ndi mainchesi a phewa, zomwe zimakhala zopindulitsa pamene phewa liyenera kutulukira mu dzenje lokwerera kuti lithandizire.
Mizere Yokulirapo komanso Yowonjezera: Zomangira izi zimakhala ndi kuphatikiza kwazinthu ziwiri zomwe tazitchulazi, zomwe zimapereka mphamvu zogwirira ntchito komanso kukulitsa mapewa.
Nayiloni Patch: Mwinanso imadziwika kuti chigamba chodzitsekera, chigawochi chimamangiriridwa ku ulusi wa bawuti ndipo, ikayika, imayambitsa mankhwala omatira omwe amatseka mwamphamvu bolt mkati mwa dzenje la ulusi.
ZOTENGA ZOSANGALATSA: Mapewa Screw OEM
Kodi kusankha zinthu za Mapewa zomangira?
Zopangira Zitsulo za Carbon: Yamphamvu komanso yotsika mtengo, koma sachedwa dzimbiri popanda chithandizo.
Zopangira Zitsulo Zosapanga dzimbiri: Chokhalitsa komanso chosagwirizana ndi dzimbiri, koma osati cholimba ngati chitsulo cha carbon.
Zopangira Zitsulo za Alloy: Mphamvu yoyenera ndi kusinthasintha, yoyenera kugwiritsidwa ntchito molemera pambuyo pa chithandizo cha kutentha.
Zida za Brass: Zabwino pamagetsi ndi matenthedwe ma conductivity, koma zocheperako komanso zomwe zimatha kuipitsidwa.
Zida za Aluminium: Wopepuka komanso wosamva dzimbiri, koma osati wamphamvu ndipo amatha ndulu akakumana ndi zitsulo zosiyanasiyana.
Pamwamba mankhwala aPhewazomangira
Zomaliza za Black oxide sizisintha makulidwe a screw ndipo zimapereka mawonekedwe a dzimbiri lakuda, lomwe limagwiritsidwa ntchito ngati zokongoletsa.
Chophimba cha Chrome chimapereka mapeto owala, onyezimira omwe ali okongoletsera komanso olimba kwambiri, ogwiritsidwa ntchito kudzera mu electroplating.
Zovala zokhala ndi zinc zimagwira ntchito ngati ma anode a nsembe, kuteteza chitsulo chapansi, ndipo zimagwiritsidwa ntchito ngati fumbi loyera loyera.
Zovala zina monga galvanization ndi phosphating ndizofala pazinthu zina za hardware, monga zomangira zomwe zimagwiritsidwa ntchito mumpanda kapena mawindo.

FAQ
Zowononga pamapewa ndi mtundu wa screw yokhala ndi shank yocheperako m'mimba mwake yopanda ulusi (mapewa) yomwe imapitilira gawo la ulusi, lomwe nthawi zambiri limagwiritsidwa ntchito popanga ma pivot kapena kuyanjanitsa pamisonkhano yamakina.
Zomangira zapamapewa zimatha kukhala zodula chifukwa cha kulondola komwe kumafunikira pakupangira kwawo komanso kugwiritsa ntchito zida zapamwamba kuti zitsimikizire kulimba ndi magwiridwe antchito.
Kulekerera kwa dzenje la screw mapewa nthawi zambiri kumadalira kagwiritsidwe ntchito ndi zosowa, koma nthawi zambiri kumakhala mkati mwa masauzande angapo a inchi kuti zitsimikizire kuti zikugwira ntchito moyenera.
Malumikizidwe okulungidwa amapangidwa ndi zomangira zomangika zomwe zimasinthidwa kukhala mabowo okhomedwa kale, pomwe zolumikizira zomata zimagwiritsa ntchito mabawuti ndi mtedza kusonkhanitsa zida.
