Mitundu ndi mawonekedwe a ma couplings

1. Kulumikizana kolimba:
• Zomwe Zilipo: Palibe kusuntha pakati pa ma shafts omwe amaloledwa, oyenera pazochitika zomwe ma shafts awiriwa ali ndi kugwirizanitsa bwino.
•Mitundu: kuphatikiza zomangira manja, zomangira zingwe, zolumikizira za flange, ndi zina.

Shaft current ndivuto lodziwika bwino komanso losapeŵeka kwa ma motors okwera kwambiri komanso ma frequency frequency motors. Shaft yapano imatha kuwononga kwambiri makina onyamula agalimoto. Pazifukwa izi, opanga magalimoto ambiri amagwiritsa ntchito njira zotsekera zotchingira kapena njira zodutsamo kuti apewe zovuta zomwe zikuchitika.

Mipiringidzo yopyapyala kapena mipiringidzo yosweka nthawi zambiri imagwiritsidwa ntchito molakwika pama injini opangira aluminiyamu. Mipiringidzo yonse yopyapyala ndi mipiringidzo yosweka imatanthawuza mipiringidzo ya rotor. Mwachidziwitso, pomwe mawonekedwe a rotor akukhomerera, kutalika kwachitsulo, ndi malo otsetsereka atsimikiziridwa, mipiringidzo ya rotor imafotokozedwa mokhazikika. Komabe, pakupanga kwenikweni, zifukwa zosiyanasiyana nthawi zambiri zimapangitsa kuti mipiringidzo yomaliza ya rotor ikhale yopotoka komanso yopunduka, ndipo ngakhale mabowo ochepera amawonekera mkati mwa mipiringidzo. Pazovuta kwambiri, mipiringidzo imatha kusweka.

Kukhazikika ndi kuwongolera kwa magwiridwe antchito amagalimoto ndi chifukwa cha kuchuluka kwa mapangidwe kumbali imodzi, ndipo kukwaniritsidwa kwa kapangidwe kazinthu kudzera munjira yopangira ndikofunikira kwambiri kumbali ina. Makamaka pankhani yolimba mkati mwa ma motors ena, ndikofunikira kuti pakhale mikhalidwe yofunikira ya kutchinjiriza kwamagetsi ndi mpweya wabwino komanso kutulutsa kutentha pakugwira ntchito kwagalimoto.

Mfundo zotsatirazi ziyenera kuganiziridwa posankha mapeto okhazikika a chithandizo cha galimoto (chomwe chimatchedwa kuti mapeto okhazikika): (1) zofunikira zowongolera molondola pazida zoyendetsedwa; (2) chikhalidwe cha katundu woyendetsedwa ndi galimoto; (3) kunyamula kapena kuphatikizika koyenera kuyenera kupirira mphamvu inayake ya axial. Kutengera zinthu zitatu zomwe tafotokozazi, mayendedwe a mpira wakuya amagwiritsidwa ntchito nthawi zambiri ngati chisankho choyamba pamagalimoto ang'onoang'ono ndi apakatikati.

Ndikusintha kosalekeza kwa zofunikira zopanga mafakitale pakuwongolera liwiro la crane, njira zachikhalidwe zoyendetsera liwiro la crane monga mawotchi ozungulira. Asynchronous Motor kuwongolera kuthamanga kwa ma rotor mndandanda, kuwongolera liwiro la thyristor stator voltage regulation komanso kuthamanga kwa cascade kuli ndi zovuta zotsatirazi: mota yozungulira yozungulira yozungulira imakhala ndi mphete ndi maburashi, zomwe zimafunikira kukonzedwa pafupipafupi. Zolephera zomwe zimachitika chifukwa cha mphete zosonkhanitsa ndi maburashi ndizofala kwambiri. Kuphatikiza apo, kugwiritsa ntchito kuchuluka kwa ma relay ndi ma contactors kumapangitsa kuti pakhale kukonza kwakukulu pamalopo, kulephera kwakukulu kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka anthu.

Chilankhulo cha Chitchaina ndi chosangalatsa kwambiri. Mawu omwewo amatha kukhala ndi zotsatira zosiyana akagwiritsidwa ntchito pazochitika zosiyanasiyana. Mwachitsanzo, mawu oti “shui bao” amatanthauza kusasamalira komanso kusiya ena. Angawonjezedwenso kutanthauza kuti okwatirana amakangana ndi kutha chifukwa cha kusagwirizana. Mawuwa amagwiritsidwa ntchito nthawi zambiri mu injini.

Lubrication ndi chikhalidwe chofunikira kuti ntchito yachibadwa ya mayendedwe agalimoto. Ma rolling bearings ndi opaka mafuta ndipo ndi omwe amagwiritsidwa ntchito kwambiri pazinthu zamagalimoto. Ma bere ogudubuza amagawidwa kukhala ma bere otseguka ndi osindikizidwa. Zimbalangondo zosindikizidwa zimadzazidwa ndi mafuta pochoka ku fakitale ndipo siziyenera kudzazidwanso pamene mukusonkhanitsa injini. Kukonzekera kwa mayendedwe kungasinthidwe molingana ndi moyo wautumiki wa injini kapena zonyamula. Kwa ma motors ambiri, mayendedwe otseguka amagwiritsidwa ntchito, ndiye kuti, wopanga magalimoto amadzaza ma berelo ndi mafuta oyenera malinga ndi momwe amagwirira ntchito.

Ntchito zambiri zamagalimoto zimakhala ndi zida zonyamula katundu, ndiye kuti, injini ikadutsa mtengo wokhazikika chifukwa chakuchulukirachulukira, malangizo ogwirizira adzaperekedwa kuti agwiritse ntchito chitetezo.

Pamene injini imakanizidwa mwamakina, kapena pali zolakwika zamagetsi monga nthaka, gawo-ndi-gawo, ndi kutembenuka, malangizo otetezera adzakhalanso ogwira mtima chifukwa cha kuwonjezeka kwamakono. Komabe, pamene panopa sichinachuluke pamtengo wotetezera, chipangizo chotetezera sichidzapereka malangizo oyenerera.

Makampani azikhalidwe zamagalimoto aku China ndi makampani opanga magalimoto. Pambuyo pazakafukufuku komanso luso laukadaulo, Xima Motor yasintha kukhala kampani yapamwamba kwambiri yamagalimoto ku China. Simo Motor imaphatikiza kapangidwe ka magalimoto, kupanga ndi kugulitsa molingana ndi mtundu. SIMO Electric Company, zopangidwa ndi Xima Electric zapambana mbiri yabwino ndipo zimatumizidwa kumayiko padziko lonse lapansi. SIMO Motor pakadali pano ndi mota yapamwamba kwambiri pakati pa zinthu zamagalimoto zaku China.
