Ngā Peera Pōro Awaawa Hōhonu Rārangi Kotahi, Rārangi Rua rānei: Ko tēhea te mea me whiriwhiri e koe?

Kupu Whakataki

Ko te whiriwhiri i waenga i ngā peera pōro rarangi kotahi me te rarangi rua he pānga nui atu i te taunga anake: ka huri i te āhua o te mīhini ki te whakahaere i te kawenga, te tere, te pakari, me te roa o te mahi. Ahakoa he rite tonu te kaupapa whakahaere taketake o ngā hoahoa e rua, he rerekē ngā āhuatanga whakahaere me ngā kaupapa matua o te hoahoa. E whakamārama ana tēnei tuhinga i ngā rerekētanga mahi i waenga i ngā whirihoranga e rua, tae atu ki te wāhi e pai ai te mahi a ia mea, ngā tauwhitinga hei tumanako, me te pānga o ngā āhuatanga pēnei i ngā kawenga radial me te axial, te wāhi e wātea ana, me te tere hurihuri ki te whakatau. Mā taua horopaki, ka māmā ake te whakataurite i te momo peera ki ngā hiahia tūturu o te tono, kaua ki te whakawhirinaki ki ngā ture matua.

He aha i whiriwhiri ai i te pōro awaawa hōhonu rarangi kotahi, rarangi rua rānei

Ngā peera pōro awaawa hohonute hoahoa peera ārai-waku e whakamahia whānuitia ana i roto i te miihini ahumahi me te miihini motuka, e whakanuia ana mō ā rātouiti te waku, iti te haruru, me te kaha ki te whakauru i ngā kawenga radial me te axial. Ahakoa e mau tonu ana ngā mātāpono whakahaere taketake puta noa i te kāwai, ko te kōwhiringa i waenga i te whirihoranga rarangi kotahi me te rarangi rua ka tino whakarerekē i ngā kaha miihini o te huihuinga hurihuri. Me whakataurite e ngā kaihangarau ngā tono kawenga, ngā here ā-wāhi, me ngā whāinga kinematic hei whakatau i te hoahoanga peera tino pai mō tētahi tono kua hoatu.

Ehara i te mea ko te taunga o te rahi anake te mea e tika ana kia whiriwhiria; engari me tino tātarihia te huringa mahi o te tono. Ehara i te mea he pai ake te peera rarangi rua nā te mea he nui ake ngā wāhanga hurihuri kei roto, ehara hoki i te mea ko te peera rarangi kotahi te whiringa tino whai hua. He mea nui te mārama ki ngā paepae mahi tika o ia momo hei whakanui ake i te wā mahi o ngā taputapu me te whakaiti i te utu katoa o te mana.

Te kōtaha kawenga, ngā rohe wāhi, me ngā whāinga tere

I te wā e hangaia ana he huihuinga hurihuri, ko te kaha kawenga me te wātea o te wāhi ngā mea matua e akiaki ana i te kōwhiringa peera. Ko ngā peera pōro awaawa hohonu rarangi kotahi (pērā i te raupapa ISO 6000, 6200, me te 6300 e kitea whānuitia ana) ka arotauhia mō te mahi tere-teitei me ngā kōtaha kawenga taurite. Ka whakaratohia e rātou he taurite pai o te tautoko kawenga radial me te kaha kawenga tuaka rua-aronga i roto i te tapuwae tuaka whaiti.

I tetahi atu taha, ko ngā peera pōro hohonu rarangi rua (pērā i te raupapa 4200 me te 4300) he mea hanga mō ngā tono ina nui ake te kawenga radial i te kaha o te peera rarangi kotahi, engari nā ngā herenga wāhi radial ka ārai i te neke ki tētahi diameter waho nui ake. Mā te whakauru i tētahi rarangi tuarua o ngā pōro, ka tukuna e ēnei peera he 1.5 ki te 1.8 ngā wā o te kaha kawenga radial hihiri o tētahi peera rarangi kotahi o te pū me te diameter waho kotahi. Heoi, ko tēnei kaha kua piki ake ka puta he whānui ake te taupoki tuaka me te whakahekenga i te tere whakahaere mōrahi e whakaaetia ana, he maha ngā wā ka heke te tere tere mā te 20% ki te 30% ki te whakataurite ki tētahi hoa rarangi kotahi.

Ngā tūponotanga o te whiriwhiri i te momo peera hē

Mā te tautuhi i tētahi whirihoranga peera hē ka puta he nama nui mō ngā mahi miihini me ngā mahi pūtea. Mā te tautuhi nui rawa i tētahi peera rarangi rua i roto i tētahi tono tere-rahi, iti-kawenga ka nui ake te waku hurihuri, ka puta he wera nui ka taea te whakaiti i te hinu whakahinuhinu, ka arahi hoki ki te pakaru o te wera wawe. Ka pau hoki te wāhi nui o te pou i te whānui o te tapuwae, ka hiahiatia pea he hoahoa whare taumaha ake, utu nui ake.

He kino anō hoki te kore e tohua he whāriki kotahi te rarangi mō te mahi taumaha. Mēnā ka nui ake ngā kawenga radial i te whakatauranga kawenga hihiri (C) i tētahi tawhiti nui, ka heke te roa o te ora ngenge o te whāriki i roto i tōna L10. Hei tauira, mā te whakahaere i tētahi whāriki kotahi te rarangi i te 120% o tōna kaha whakatauranga ka taea te whakaiti i tōna roa o te mahi mā te neke atu i te 40%, ka hua ake he pakaru tere o te ara reihi, he pakaru kino o te whare herehere, me te wā kore mahi o te mīhini i whakaritea.

Ngā Rerekētanga Hanganga me te Mahi

Ko ngā rerekētanga hoahoa i waenga i ngā peera pōro awaawa hohonu rarangi kotahi me te rarangi rua e whakatau ana i ō rāua rohe mahi. Ahakoa e whakamahi ana ngā mea e rua i ngā awaawa ara tere hohonu, tonu i hangaia hei whakatutuki i te taumata teitei o te ōrite ki ngā huānga hurihuri, he rerekē rawa te āhua o roto me te pakari o te hanganga.

Te āhua o roto, te hoahoa ara reihi, me te tāpiritanga pōro

Ko ngā peera rarangi kotahi he ara rere korekore i runga i ngā mowhiti o roto me waho, e āhei ai rātou ki te tautoko i ngā kawenga tuaka i ngā taha e rua me te kore he raruraru. Ko te nuinga o te wā ka whakanuia te tāpiritanga pōro mā te tikanga huihuinga nekehanga rerekē, e kore e hiahiatia he mokowā whakakī. He mea nui tēnei āhua o te ara rere korekore hei pupuri i te iti o te wiri me te haruru i ngā auau hurihuri teitei.

Kei roto i ngā peera rarangi rua ngā ara rere whakarara e rua. I runga i te kaihanga me te raupapa motuhake, ka whakamahia e ētahi peera rarangi rua ngā mokowā whakakī hei whakauru i te maha o ngā pōro, ka nui ake te kaha o te kawenga radial. Heoi, ko te noho mai o te mokowā whakakī ka pakaru te haere tonu o te pakihiwi ara rere. Ko ngā peera me ngā mokowā whakakī he tino herea ki te whakahaere i ngā kawenga axial, nā te mea ka panaia ngā pōro e ngā kaha pana nui ki ngā taha mokowā, ka puta he kino tonu. Kei te wātea ngā hoahoa rarangi rua mokowā kore-whakakī, ā, he pai ake te tautoko axial rua-aronga, ahakoa he iti ake te kaha radial i ērā he mokowā.

Te kaha ki te tere, te pakari, me te manawanui ki te hē o te tūnga

He rerekē rawa te mahi hihiri ina aromatawaihia te tere, te pakari, me te manawanui ki te hē o te whakarara. He iti ake te waku o roto o ngā peera rarangi kotahi nā te iti ake o ngā hononga hurihuri me ngā hoahoa whare herehere māmā ake. Mā tēnei ka taea e ngā peera rarangi kotahi paerewa te eke ki te tere neke atu i te 30,000 RPM i roto i ngā rahi poka iti ake. Hei tāpiri, he iti noa te ngāwari o ngā peera rarangi kotahi, e manawanui ana ki ngā hē koki o te 2 ki te 10 meneti o te pewa me te kore e pāngia e te taumahatanga taha nui.

He pakari ake ngā peera rarangi rua. Mā te āhua takirua-pā ka hangaia he hanganga tautoko tino pakari e ātete ana ki te piko o te pou. Ahakoa he pai mō te pupuri i te tūnga tika o te pou i raro i ngā kawenga taumaha, nā tēnei pakari ka tino aro atu ngā peera rarangi rua ki te hē o te tūnga. I te nuinga o te wā ka taea e rātou te manawanui ki te 2 meneti noa iho o te pewa. Ko te hē o te tūnga i tua atu i tēnei paepae kuiti ka akiaki i te tohatoha kawenga kore taurite i waenga i ngā rarangi e rua, ka tere ake te pakaru o te rarangi kua taumaha rawa.

Ripanga whakatairite rarangi kotahi me rarangi rua

E whakaatu ana te ripanga e whai ake nei i ngā rerekētanga matua ā-pūkaha me te mahi i waenga i ngā peera pōro awaawa hohonu rarangi kotahi me te rarangi rua paerewa, he rite te whānui o te poka me te whānui o waho.

Me pēhea te aromatawai i te peera tika mō tō tono

Ko te whiriwhiri i te peera tino pai me whai aromatawai pūnaha o te taiao miihini. Me neke atu ngā kaihangarau i ngā rahinga taketake o te rarangi pukapuka, me te tātari i ngā taurangi hihiri motuhake, ngā here ā-wāhi, me ngā pānga ōhanga roa o te tono.

Ngā taurangi mahi matua hei aromatawai tuatahi

Me tīmata te tukanga aromatawai me te tatau tika i te kawenga whārite hihiri (P), mā te whakamahi i te tātai paerewa ISO: P = XFr + YKo Fa, ko Fr te kawenga radial, ko Fa te kawenga axial, ā, ko X me Y ngā tauwehenga kawenga radial me axial. He mea nui tēnei uara hei whakatau i te whakatauranga kawenga hihiri taketake (C) e hiahiatia ana mō te peera.

Kia inehia te kawenga, me whakatū e ngā kaihangarau te roanga o te oranga ngenge L10h. Hei tauira, ko ngā taputapu whare noa e hiahiatia ana he roanga L10h o te 2,000 ki te 4,000 hāora, e āhei ai te whāriki rarangi kotahi māmā ake. He rerekē, ko te mahi tonungā motuka ahumahiHe maha ngā wā e hiahiatia ana e ngā roera mira pepa kia neke atu i te 40,000 hāora te roa o te ora o ngā mira L10 hāora. Mēnā kāore e taea e te peera rarangi kotahi te whakatutuki i tēnei roa o te ora i raro i te kawenga kua tatauhia me te kore e whakanui ake i te diameter o waho, ko te peera rarangi rua te otinga hangarau e tika ana.

Ngā herenga mō te whare, te pou, me te whakairinga

He tino herenga te hoahoa o te whare me te poupou ki te kōwhiringa peera. Ko te whānui o te papa o te peera rarangi rua e hiahia ana kia roa ake te nohoanga o te poupou me te hohonu ake te poka o te whare. Mena kaore e taea e te hoahoa miihini huri noa te whakauru i tenei whanui kua piki ake, tera pea ka akiakihia nga miihini ki te whakamahi i nga peera rarangi kotahi e rua, ka puta he uaua ki te whakakoi me te whakatikatika.

Hei tāpiritanga, me pupuri tonu ngā ātete hononga kua tautuhia e ngā paerewa taunga ISO (hei tauira, j5/k5 mō ngā toki hurihuri, H6/J6 mō ngā whare tūmau). Nā te mea he tino tairongo ngā peera rarangi rua ki te hē o te tūnga, me mīhini te toki kia kaha ake te whakawhāiti me te tika. Mena he ngāwari te hoahoa o te toki ki te piko i raro i te kawenga (neke atu i te 2 meneti te piko), ka pāngia te peera rarangi rua e te kawenga taha kino, ka waiho hei kōwhiringa kāore i te tika ahakoa te kaha kawenga ariā teitei.

Te utu mō te huringa ora, te tiaki, me te mōrearea o te rahunga

Ko te utu katoa o te mana whakahaere he nui atu i te utu hoko tuatahi. Ko te utu mō ngā peera rarangi rua he 40% ki te 70% te nuinga o te wā i runga ake i ngā momo rarangi kotahi o te rahi pūwero kotahi, nā te nui ake o te whakamahinga rauemi me ngā tukanga hanga me te huihuinga uaua ake.

Heoi anō, me whai whakaaro ngā utu o te huringa ora ki ngā wā tiaki me ngā mōrearea rahunga. Mena kei te mahi te peera rarangi kotahi i te rohe tino kaha o tōna kawenga, ka tere te pikinga o te auau tiaki, te pakaru hinu, me te mōrearea o te rahunga kino ki te penapena i te wā o mua. I tetahi atu taha, mā te whakamahi i te peera rarangi rua i roto i te tono tino pakari, taumaha hoki ka taea te whakaroa i te wā waenga i waenga i ngā rahunga (MTBF) mā ngā mano hāora, ka tino whakaiti i ngā whakapaunga tiaki mō te wā roa.

Ngā Take Hoko, Kounga, me te Whakatutukitanga

Haunga te rahi ariā me te aromatawai miihini, ko te mahi ā-tinana o te peera e whakawhirinaki nui ana ki ngā paerewa hanga, te kounga rauemi, me te whakahaere mekameka tuku pakari. Me whakarite e ngā tīma hoko me te whakaū kounga kei te tutuki ngā peera kua tohua i ngā inenga ture ā-ao.

Te akomanga manawanui, te ātea, te hiri, me ngā rauemi o te whare herehere

Me tohu ngā peera i runga i ngā akomanga manawanui kua mōhiotia, pērā i te tauine ABEC (ABEC 1, 3, 5, 7) me ngā taurite ISO (P0, P6, P5, P4). Mō ngā tono ahumahi paerewa, he rawaka te ABEC 1 / ISO P0, engaringā taputapu mīhini tino tikaMe whai ABEC 5 / ISO P5 pea hei whakaiti i te oma. He mea nui anō hoki te āputaputa ā-roto; ko ngā peera e mahi ana i ngā taiao pāmahana teitei (neke atu i te 100°C) me ngā taunga pokanoa nui rānei, me tohu ki te āputaputa C3, C4 rānei hei ārai i te herenga ā-roto nā te whānui o te wera.

Ko ngā rauemi hiri me ngā rauemi whare herehere e whakatau ana i te pai mō te taiao. Ko ngā hiri whakapā (pēnei i ngā hiri rapa 2RS) he tino pai te tiaki i te urunga mai o ngā matūriki engari ka puta he waku e whakaiti ana i te tere mōrahi tae atu ki te 20%. Ka taea e ngā parepare whakarewa kore-pā (ZZ) te tere ake engari he iti ake te tiaki i ngā wai. He rerekē anō hoki ngā rauemi whare herehere i runga i te mahi: he maha ngā whakamahinga o ngā whare herehere maitai kua tāia, ko ngā whare herehere polyamide kua whakapakarihia ki te muka karāhe (PA66) he iti te waku engari he iti noa te here ki ngā pāmahana mahi i raro i te 120°C. Mō te wiri nui, mō ngā pāmahana tino kino rānei, he pai ake ngā whare herehere parahi mīhini.

Te tohu mō te kaiwhakarato, te whai i ngā whakaritenga, me te tirotiro

Hei whakarite i te pono o te peera, me whai tohu paetae tino pakari mai i ngā kaiwhakarato. Me whai tiwhikete ngā kaihanga pēnei i te ISO 9001, IATF 16949 rānei (mō ngā tono motuka), kia pakari ai.ngā pūnaha whakahaere koungaKāore e taea te whiriwhiri i te whai i ngā rauemi; me hanga ngā peera pōro hohonu kounga teitei mai i te maitai peera tango hau korehau (hei tauira, 100Cr6, SAE 52100 rānei) kua whakamahanahia kia rite te pakeke o te 58 ki te 65 HRC.

Me uru ki ngā tirotirohanga mana kounga te whakamātautau pakari mō te haruru me te wiri (he maha ngā wā ka whakarōpūtia i raro i ngā paerewa pēnei i te Z1/V1 ki te Z4/V4), me te manatoko i ngā āhuatanga. Mō ngā tono rererangi nui, hauora rānei, me tino whakahaere te reiti hapa e whakaaetia ana, me te whakahau kia iti iho i te 50 Wāhanga Ia Miriona (PPM). Me tono ngā tīma hoko i ngā pūrongo tirotiro whānui me ngā tiwhikete rauemi hei manatoko i te tutuki i mua i te whakamana i te tāutanga papatipu.

Te Tukanga Kōwhiri me ngā Tauira Tono

Ko te whakawhiti mai i te aromatawai ariā ki te whakatakotoranga whakamutunga me whai tikanga hanganga hei whakarite kia arohia ngā taurangi ā-pūkaha, ā-wāhi, me te ā-ōhanga katoa. Mā te whakamahi i tētahi anga whakatau taahiraa-i-te-taahiraa ka ārai i te tirotiro nui, ā, ka whakamana i te taurite tono tino pai.

Te tukanga whakatau taahiraa-i-te-taahiraa

Me whai i tētahi rārangi arowhai pūnaha te tukanga whiriwhiri pakari hei wehewehe i te whirihoranga tika o te peera. Tuatahi, maherehia ngā whārite kawenga tuatahi hei whakatau mēnā ko ngā kaha radial, ko ngā kaha tuaka rānei te mea nui. Tuarua, whakatūria te RPM whakahaere mōrahi, ā, manatokohia ki te tere tohutoro wera o te peera. Tuatoru, tatauhia te roanga ngenge L10h e hiahiatia ana i runga i te kawenga hihiri ōrite. Hei whakamutunga, aromatawaihia te wāhi tuaka e wātea ana i roto i te whare.

Hei whakahaere i tēnei tukanga, ka taea e ngā kaihangarau tewhakamahia te matihiko whakatau e whai ake neikia tere te tautuhi i te hoahoa peera tino tika i runga i ngā tawhā tono matua.

Ngā Pātai Auau

Āhea ahau me whiriwhiri i tētahi whāriki pōro awaawa hohonu kotahi te rarangi?

Kōwhiria te rarangi kotahi mō ngā mahi tere-nui, kawenga-waenga, me te iti o te wāhi tuaka, pērā i ngā motuka, ngā pā, me ngā kaikawe.

Āhea te wā pai ake ai te whakamahi i te peera pōro hohonu rarangi rua?

Whakamahia te rarangi rua ina teitei ake ngā kawenga radial engari kāore e taea te whakanui ake i te diameter o waho. Ka tukuna e ia te kaha radial tata ki te 1.5–1.8× me te whāriki whānui ake.

Ka taea e te peera pōro awaawa hohonu rarangi rua te whakahaere i te tere ake?

Kāo. Ko te tikanga, ka 20%–30% te puhoi o te oma o ngā peera rarangi rua i ngā momo peera rarangi kotahi rite tonu nā te nui ake o te waku me te whakaputa wera.

Ka taea e ngā peera pōro awaawa hohonu rarangi rua te kawe i te kawenga axial i ngā taha e rua?

Ka taea e ētahi, engari he iti te kaha o ngā hoahoa me ngā mokowā whakakī. Tirohia ngā raraunga raupapa me te putumōhio i mua i te whakamahinga i raro i te kawenga pana.

Me pēhea te āwhina a DEMY i ahau ki te whiriwhiri i te peera pōro hohonu e tika ana?
