Indlela yokukhetha iibheringi ezikumgangatho ophezulu kwizicelo zeemoto zombane: Isikhokelo esipheleleyo

Iimoto zombane zimele enye yezona zicelo zixhaphakileyo zeebheringi kwihlabathi liphela. Imarike yeemoto zombane zehlabathi, exabisa malungaI-150 yeebhiliyoni zeerandi ngo-2023, ixhomekeke kakhulu kwiibheringi ezicwangciswe ngokuchanekileyo ukuqinisekisa ukusebenza kakuhle, ukuhlala ixesha elide, kunye nokusebenza okuzinzileyo. Izifundo zibonisa ukuba ukusilela kweebheringi kubangela phantse ukubaAma-40% azo zonke iimoto zombane ezingasebenzi kakuhle, nto leyo eyenza ukuba ukhetho oluchanekileyo lweebheringi lube lubalulekile ekunciphiseni iindleko zokugcina nokuthembeka kokusebenza.

Esi sikhokelo sinika ulwazi olusebenzisekayo kwiinjineli zokuthenga, abaphathi bolondolozo, kunye neenjineli zoyilo ezifuna ukukhetha iibheringi ezifanelekileyo zokusetyenziswa kweemoto zombane. Iingcebiso zithathwe kwimigangatho yamazwe ngamazwe epapashwe yimibutho equka i-International Organisation for Standardization (ISO) kunye ne-American Bearing Manufacturers Association (ABMA).

Zithini iiBearings zeeMoto kwaye Kutheni Zibalulekile?

Iibheringi zeemoto zizinto ezichanekileyo ezifakwe kwiimoto zombane ukuxhasa imingxunya ejikelezayo, ukunciphisa ukungqubana, kunye nokugcina ulungelelwaniso olufanelekileyo phakathi kweendawo ezingashukumiyo nezijikelezayo.

Imisebenzi ephambili yeebheringi zeemoto ibandakanya:

1. Inkxaso ye-radial— amandla amelanayo athe nkqo kwi-axis yeshaft
2. Indawo ye-Axial— ukugcina indawo echanekileyo yeshaft kuzo zombini iindlela
3. Ukunciphisa ukungqubana— okuvumela ukujikeleza okuthe tye kunye nokulahleka kwamandla okuncinci
4. Ukusasazwa kobushushu— ukwenza kube lula ukudluliselwa kobushushu kude neendawo ezibalulekileyo zoqhagamshelwano

Ngokungafaniyo neebheringi zenjongo eqhelekileyo, iibheringi zeemoto kufuneka zihlangabezane nemigangatho engqongqo yokukhupha ingxolo, amanqanaba okungcangcazela, kunye nobomi bokusebenza. Ukukhetha iibheringi ngokunganelanga kunokukhokelela ekuwohlokeni kokusetyenziswa kwamandla, ukungasebenzi kakuhle kwangethuba, kunye nokungasebenzi kakuhle okungabizi kakhulu okungacwangciswanga.

Zeziphi iintlobo zeebhereyitha ezifanelekileyo kakhulu kwiiMoto zoMbane?

Ukusetyenziswa kweemoto zombane kudla ngokusebenzisa iindidi ezintathu eziphambili zeebhereyitha. Uhlobo ngalunye lunezibonelelo ezahlukeneyo ngokuxhomekeke kwiimeko zomthwalo, iimfuno zesantya, kunye neemeko zokusingqongileyo.

Iibheringi zeBhola eNzulu yeGroove

Iibheringi zebhola ezinzulu ze-groove ziyindlela eqhelekileyo yokuxhasa ishaft yemoto yombane. Umgangatho we-ISO 15 uchaza iiparameter zazo zobukhulu kunye nokusebenza. Iimpawu eziphambili ziquka:

• Umthamo womthwalo:Ifanelekile kwimithwalo edibeneyo ye-radial kunye ne-axial ukuya kuthi ga kwi-35% yomlinganiselo osisiseko womthwalo we-bearing ozinzileyo

• Ukunyamezelana kokungalungelelani:Ukuya kuthi ga kwi-0.5 degrees kuxhomekeke kuluhlu lweebhereyitha

Iibheringi Ezifakwe I-Insulation (iCeramic Hybrid)

Kwizicelo ze-variable frequency drive (VFD) apho ukugqwala kombane kubeka umngcipheko, ii-insulated bearings—ezine-ceramic rolling elements okanye iindawo ezine-oxide-coated surfaces—zithintela ukudlula komsinga olahlekileyo kwindlela yokukhwela iibheringi. Uphando olupapashwe yi-IEEE Industry Applications Society lubonisa ukuba amaxabiso okumelana nokugquma angaphezulu.20 MΩ kwi-500V DCithintela ngempumelelo imisinga yombane eyingozi.

Ungazivavanya njani iziqinisekiso zoMgangatho weeBheari?

Iziqinisekiso zomgangatho we-bearing zibonelela ngokuqinisekiswa okucacileyo komntu wesithathu kokungqinelana kokwenziwa kunye nokusebenza kwemveliso. Amaqela okuthenga kufuneka aqinisekise ezi nkqubo zilandelayo zeziqinisekiso:

Indawo yokuvelisa ye-DEMY iyasebenzaISO/TS16949:2009isiqinisekiso—umgangatho wolawulo lomgangatho owenzelwe ngokukodwa ababoneleli bezinto zezithuthi nezothutho. Esi siqinisekiso sidlula iimfuno ezisemgangathweni ze-ISO 9001 ngokubandakanya imo yokusilela kwenkqubo kunye nohlalutyo lweziphumo (FMEA), ulawulo lwenkqubo yezibalo (SPC), kunye neenkqubo zokuceba umgangatho wemveliso eziphambili (APQP).

Abathengi kufuneka bacele izatifikethi zokuthobela imithetho (CoC) baze baqinisekise ukulandeleka kwebhetshi. Ukuze ufumane isikhokelo esineenkcukacha malunga nokuqinisekiswa komgangatho weebheringi, jonga kuIsishwankathelo somgangatho wesiqinisekiso se-DEMY.
