Kutenderera… zvizvarwa

Sezvaunoziva, mazhinji emhando dzemotokari dzakakurumbira dzakagadzirwa nhasi ndeyekumberi-mavhiri. Nokudaro, kuita chisarudzo chakadaro kunofanira kutungamirira kushandiswa kwehutano hwakakwana hwakakwana hwekutakura mavhiri. Nekuda kwemasimba makuru anoshanda pamavhiri panguva yekufamba, iyo inonzi kaviri-mutsara angular contact ball bearings inomuka. Parizvino, chizvarwa chavo chechitatu chakatoiswa mumotokari, pasinei nehukuru uye chinangwa chemuenzaniso wemotokari iyi.

Pakutanga kwaive nemapundu ...

Havasi vese vanofarira mota vanoziva kuti simbi yebhora mabearings aive asiri ekutanga kushandiswa mumotokari, pamberi pekuuya kwemota dzinotyaira mavhiri emberi, rudzi rusina basa rwetapered roller bearings inotongwa. Pasinei nekureruka kwekugadzirwa kwayo, yakanga ine zvipingamupinyi zvakawanda zvakakosha. Chinhu chikuru chakashata uye kukanganisa kwakakomba kwetapered roller bearings kwaive kudiwa kwekugadziriswa nguva nenguva kweaxial clearance uye lubrication. Izvi zvinokanganisa hazvichavepo mune zvemazuva ano angular contact ball bearings. Pamusoro pekuti ive isina gadziriso-yemahara, iwo zvakare akasimba zvakanyanya kupfuura iwo conical.

Bhatani kana (yakazara) kubatana

Chizvarwa chechitatu cheaviri-mutsara angular kuonana bhora mabhengi anogona kuwanikwa mumotokari dzakagadzirwa nhasi. Zvichienzaniswa neyekare, ivo vakanyanya kufambira mberi kwetekinoroji, uye pamusoro pezvose, basa ravo rinobva pane yakasiyana hunyanzvi mhinduro yakabatana negungano ravo. Saka zvizvarwa izvi zvakasiyana sei kubva kune chimwe nechimwe? Iyo yakapfava kaviri mutsara angular yekubata bhora mabearings echizvarwa chekutanga akaiswa pane iyo inonzi "Push" mucrossover seat. Zvakare, mamwe mabhengi echizvarwa chechipiri anosiyaniswa nekubatanidzwa kwawo negumbo hub. Muchizvarwa chechitatu chepamusoro-soro chetekinoroji, kaviri-mutsara angular kuonana bhora rinoshanda mukubatana kusinga patsanuke pakati pehubhu uye knuckle yekutungamirira. Mabheji echizvarwa chekutanga anogona kuwanikwa kunyanya mumhando dzemotokari dzekare, incl. Opel Kadett uye Astra I, wechipiri, somuenzaniso, muNissan Primera. Zvakare, chizvarwa chechitatu chekaviri-mutsara angular kuonana bhora bheri inogona kuwanikwa - iyo, zvichida, ichashamisa vazhinji - mudiki Fiat Panda uye muFord Mondeo.

Pitting, asi kwete chete

Maererano nenyanzvi, kaviri-mutsara angular contact ball bearings anogara kwenguva refu: zvakakwana kutaura kuti kubva pakuona teknolojia, inofanira kugara kusvika kumakore gumi nemashanu ekushanda. Izvi zvakawanda, asi, zvinosuruvarisa, muzviitiko zvakawanda chete mudzidziso. Nei kudzidzira kuchiratidza zvakasiyana? Pakati pezvimwe zvinhu, hupenyu hwebasa hwemavhiri mavhiri hunoderedzwa. kuenderera mberi kupera kwepamusoro pezvinhu zvavakagadzirwa kubva. Mumutauro wenyanzvi, chirwere ichi chinonzi pitting. Kaviri mutsara angular yekubata bhora mabearings zvakare haibatsire mukupinda kwemhando dzakasiyana dzezvinosvibisa. Izvi zvinokanganisa kukuvara kunofambira mberi kune vhiri hub seal. Uyezve, kuputika kwenguva refu kwemavhiri epamberi kunogona kuratidza kuti kutakura kunobatwa nekuora, iyo, uyezve, yakapinda mukati mukati mayo. Chimwe chiratidzo cheimwe yemabheya asingashande nemazvo ndeyekuzunguzika kwevhiri, iro rinobva raendeswa kune yese dhiraivha yemotokari. Tinogona kutarisa zviri nyore kuti chii chakakanganisika. Kuti uite izvi, simudza mota pane inosimudza uye wobva wafambisa mavhiri epamberi munzira inochinjika uye uchienderana neakisi yavo yekutenderera.

Kutsiva, ndiko kuti, kusvina kana kusunungura

Chibereko chakakuvadzwa, pasinei nokuti chizvarwa chipi, chinogona kutsiviwa zviri nyore. Panyaya yemhando dzemhinduro dzekare, semuenzaniso. chizvarwa chekutanga, kutakura kwakakuvadzwa kunotsiviwa uye kuiswa mune yakanaka mamiriro nekuitsikirira nebhuku re hydraulic press. Zvinotonyanya nyore kuita izvi munyaya yemabhengi emhando yekupedzisira, i.e. chizvarwa chechitatu. Kuti uite kutsiva kwakaringana, ingo sunungura wobva wasimbisa masiruu mashoma. Ndokumbira utarise, zvisinei, usakanganwa kuvasimbisa kune chaiyo torque uchishandisa torque wrench.
