Ko te āhua ā-roto me te hanganga rauemi o ngā peera pōro awaawa hohonu e whakatau ana i ō rātou rohe mahi. He mea nui te arotau i ēnei wāhanga o roto hei whakaiti i te whakaputanga wera, hei whakahaere i te ahotea porowhita, me te ārai i te ngenge wawe i ngā tere teitei.

Ko ēhea ngā āhuatanga hoahoa e tautoko ana i ngā tere teitei ake

Ko te hanganga taketake o te DGBB he hohonu, he kore e mutu ngā awaawa ara reihi e piri tata ana ki ngā huānga hurihuri porowhita. Ko tēnei ōwehenga rite—e hangaia ana i waenga i te 51% me te 53% o te whānui o te pōro—ka patu i tētahi taurite miihini nui. Mā te rite pūmau ka whakanui ake i te kaha kawenga katoa engari ka puta he waku nui me te wera i ngā tere teitei, ko te rite ngāwari ka whakaiti i te waku engari ka whakararu i te tohatoha kawenga. Mā tēnei arotautanga āhuahanga tika ka taea e te peera te whakahaere i ngā kawenga radial ngawari me ngā kawenga tuaka rua-aronga i te wā kotahi me te kore e wera rawa.

Te pānga o te hoahoa o te whare herehere, te ātea, me te tika ki te mahi

I ngā tere hurihuri tino nui, ka ngāwari te pakaru o ngā kēhi maitai kua tāia ki te paerewa nā te kaha o te nekehanga me te kore taurite hihiri. Nō reira,ngā tono tere-teiteihe maha ngā wā ka whakamahia ngā whare parahi mīhini, te kapia phenolic, ngā whare polyetheretherketone (PEEK) rānei, e tuku ana i te pumau pai ake me te taumaha iti ake. Me tohu hoki e ngā kaihangarau ngā āputa ā-roto e tika ana, pērā i te C3, i te C4 rānei, hei whakauru i te whānui wera o te mowhiti o roto i puta mai i te waku tere-tiketike. He mea nui anō hoki te tika; mā te tohu i ngā manawanui ISO P4 (ABEC 7) ka whakarite i te tika o ngā āhuatanga, ka whakaiti nui i te oma me te wiri whakangaro i ngā auau teitei.

Ko ēhea rauemi me te maimoatanga wera e whakapai ake ana i te roa o te ora ngenge

Ahakoa ko te maitai chromium waro-teitei (AISI 52100) tonu te paerewa ahumahi, he mea nui te whakarewa me ngā maimoatanga matatau mō ngā huringa mahi tino uaua. Ka whakaitihia e te maitai tango-hau korehau ngā whakaurunga kore-whakarewa, ka roa ake te roa o te ora ngenge o raro i te mata o ngā ara reihi. Mō ngā tikanga tere-nui tino uaua, ka whakamahia e ngā miihini ngā peera ranu kei roto ko ngā pōro uku silicon nitride (Si3N4). Tata ki te 40% te iti iho o te mātotoru o ngā pōro uku i ō rātou hoa maitai. Mā tēnei whakaiti papatipu ka tino whakawhāitihia te kawenga centrifugal i runga i te ara reihi o waho, ā, ka whakaitihia ngā pāmahana whakahaere, ka roa ake te ora o te peera me te hinu whakahinuhinu.

Te Whakataurite o ngā Bearings Pōro Awaawa Hōhonu ki ētahi atu Momo Bearings

Ko te whiriwhiri i te whirihoranga peera tino pai me whakataurite tika i te whanonga kinematic, te tohatoha kawenga, me ngā tauwehenga waku puta noa i ngā hoahoa huānga hurihuri rerekē. Ahakoa he maha ngā momo peera e tautoko ana i te nekehanga hurihuri, he rerekē rawa ō rātou tere-teitei.

Ko te wāhi e pai ake ai tā rātou mahi i ngā peera whakapā koki me ngā peera roera

He rerekē ngā painga o ngā DGBB i ngā peera pōro whakapā koki (ACBB) mengā peera roera porotakai roto i ngā āhuatanga tere-teitei motuhake. Ahakoa he pai ake te kaha o ngā peera roera porotaka, ka nui ake te waku o te āhua o te hononga-rārangi, ka ārai i te paepae tere mōrahi. I tua atu, ka whakamahia e ngā DGBB te hononga pūwāhi, ka whakaitihia te taipana waku. Ki te whakatauritea ki ngā ACBB, e hiahia ana ki te utaina mua tuaka tika me ngā whakaritenga takirua hei whakahaere i te pana rua-ara, ka taea e te DGBB kotahi te whakauru i te pana i ngā taha e rua, ka māmā ake te hoahoa o te pou me te whakaiti i te uaua o te huihuinga.

Ko ēhea ngā āhuatanga mahi hei whakataurite

Me arotake e ngā kaihangarau te taipana waku, te marara wera, me ngā tere whakawhāiti ina whakatauritea ana ngā momo peera. Ko te mahi tere-tiketike e tino whakatauhia ana e te kaha o te peera ki te mahi me te kore e whakaputa wera nui e whakaiti ana i te hinu whakahinuhinu. Kei te whakaatu te ripanga i raro nei i ngā inenga whakatairite noa mō ngā peera paerewa o ngā rahinga poka rite e mahi ana i raro i ngā āhuatanga tere-tiketike.

Ngā mea e tika ana kia whakaarohia e ngā kaihangarau taupatupatu

Ko te painga matua i te wā e whiriwhiri ana i tētahi DGBB i runga i tētahi ACBB ko te herenga o te kaha kawenga tuaka. Ka mahi ngā DGBB me te koki whakapā 0° noa iho, engari ko ngā ACBB he koki whakapā hangarau mai i te 15° ki te 40°, e āhei ai rātou ki te tautoko i ngā kawenga pana teitei ake. Mena he kaha tuaka matua, he kaha taumaha kei roto i tētahi tono tere-teitei—pērā i roto i ngā miro taputapu mīhini motuhake, i ngā papu mahi-taumaha rānei—tērā pea ka pāngia te DGBB e te ngenge wawe o te ara reihi. Me paunatia e ngā kaihangarau te māmā o te miihini me te iti o te waku turanga o te DGBB ki ngā kaha pana pakari, kotahi-aronga o ngā kōwhiringa whakapā koki.

Te pānga o te whakatauranga tere me te whakatauranga kawenga ki te kōwhiringa

Ko te whakatauranga kawenga hihiri (C) me te tere tohutoro wera ngā inenga matua i roto i te tukanga whiriwhiri. Ahakoa he tohu te whakatauranga kawenga teitei i te ātete kaha ki te ngenge, ko te rahi rawa o te peera mō te tono tere teitei ka tino kino. Ka whakanui ake ngā huānga hurihuri nui ake i ngā kaha centrifugal me te waku ā-roto, ka whakaiti i te tere whakawhāiti. Ko te tikanga, ko te whāinga a ngā miihini he L10h te roa o te whakatauranga taketake neke atu i te 10,000 hāora mā te āta whakataurite i te kaha hihiri e hiahiatia ana me te tapuwae tinana e pupuri ana i te tawhiti tere whakahaere haumaru.

He aha te mea nui ai te whakahinuhinu me te hiri

I ngā tere teitei, ka wehea ngā huānga hurihuri mai i ngā ara rere e te matotoru o te kiriata waiora, ka ārai i te pa o te konganuku ki te konganuku. Mō ngā DGBB kua pania ki te hinu, ka tino whakahaerehia te rahinga whakakī hinu—e 25% ki te 30% o te wāhi o roto o te peera—hei ārai i te hurihuri me te whakaputa wera nui. He mahi nui anō hoki tā ngā tikanga hiri; ka hangaia e ngā hiri whakapā paerewa (RS) te kaha ā-hauora me te tōia tinana. Nō reira, me whakamahi ngā tono tere teitei i ngā hiri labyrinth kore-pa (RZ, ZZ rānei) e ārai ana i ngā poke me te kore e pāngia e te whiu tere waku.

Te pānga o te manawanui, te wiri, te haruru, me te utaina mua ki ngā hua

Ka whakanuia e te tere hurihuri teitei ngā hapa iti o te taha, ka hua ake te haruru kino me te tere o te kakahu. Mā te tautuhi i ngā manawanui kikī (ABEC 5, teitei ake rānei) me ngā akomanga wiri kaha (pēnei i te V3, V4 rānei) ka maeneene te mahi. Hei tāpiri, mā te whakamahi i te utaina mua tuaka whakahaeretia ka whakakorea te ātea o roto, ka pumau te kinematics o te pōro, ā, ka ārai i te paheke i te wā tere o te whakaterenga.

He aha te tukanga whiriwhiri me whai e ngā kaihoko me ngā kaihangarau

Ka tīmata te tukanga whiriwhiri me te mahere whānui o te kōtaha kawenga-tere. Me tatau e ngā miihini ngā kaha radial, te pana axial, ngā pāmahana whakahaere, me te RPM tihi. Ko ngā peera maitai paerewa 52100 ka whakapūmauhia te rahinga mō ngā pāmahana whakahaere tae atu ki te 120°C. Mena ka nui ake te wera ā-rohe i tēnei paepae i te tono tere-teitei, me tohu e ngā kaihoko ngā momo whakapūmau-wera (hei tauira, ngā mowhiti S0, S1 rānei) hei ārai i te whānui kino o te rahinga, te ngaronga o te ātea, me te hopunga i muri mai i te wā e whakahaerehia ana.

Ko ēhea ngā tirotiro pūtake me te kounga e whakaiti ana i te mōrearea

Ko te whakaiti i te mōrearea o te mekameka tuku ko te whai i ngā tikanga tohu paetae me te whakapumautanga kounga a ngā kaiwhakarato. Ko te rapu i ngā DGBB tere-rahi me manatoko i ngā tiwhikete rauemi, me te whakarite kia whakamahia he maitai tino ma, he rino tango hau korehau.Ngā arowhai whakahaere koungame uru atu ki te arotake i ngā pūrongo inenga a te kaihanga mō ngā tawhā nui. Hei tauira, ko ngā tono tere-tiketike e hiahia ana kia iti iho i te 2.5 maikiromita te oma radial hei whakarite i te pumau hihiri. Mā te whakamātautau puranga motuhake mō te wiri me ngā tukunga oro ka tiakina anō mai i ngā rahunga mara wawe.

He aha ngā aratohu whakatau whakamutunga hei whakamahi

Me ārahi ngā whakataunga hokohoko whakamutunga e tētahiTe Utu Katoa o te Mana Whakahaere(TCO) kaua ko te utu kotahi anake. Ahakoa he nui te utu mō ngā DGBB uku ranu, ngā peera ABEC 7 tino tika rānei, ko te roa o te ora ratonga, te poto o ngā wā tiaki, me ngā whakaritenga whakahinuhinu iti iho ka hua ake he TCO iti iho i roto i ngā mīhini tere-nui. Mā te whakataurite i ngā whakatakotoranga hangarau ki ngā tauira ōhanga huringa ora, ka taea e ngā whakahaere te whakatutuki i te pono me te whai huatanga whakahaere tino pai i roto i ā rātou pūnaha hurihuri tere-nui.
