Te Whakaiti i te Pakaru o te Fretting i roto i ngā Hononga Poraka Whakamutunga Wiri-Teitei mō ngā Whakamahinga Motuka

Ngā Otinga Hangarau Matatau mō ngā Kaiwhakarato Waka Taumata-1, te Hoko Aunoatanga Ahumahi, me ngā Kaiwhakauru Rerewe

Te Whai i te Pūtake o te Pono o te Wiri-Tiketike

I roto i ngā pūnaha hikohiko hou, he mea tino nui te pupuri i tētahi hononga hiko pumau i raro i te ahotea miihini nui. Ngā Kaihanga Hoahoa Kaiwhakarato Hiko Waka Taumata-1, ko te tautuhi i ngā poraka whakamutunga mō ngā kōwae whakahaere miihini (ECM) me ngā atanga pūoko me whai wāhanga ka taea te tu atu i ngā taiao tino kino o raro i te tuanui. Waihoki, Ngā Kaiwhakahaere Hoko Taputapu Aunoatanga Ahumahi te kimi poraka whakamutunga mō ngā mīhini wiri nui, me Ngā Kaiwhakauru Pūnaha Hiko mō te Waka Tereina I te aromatawai i ngā hononga reriwe DIN mō ngā tono waka hurihuri, he hoariri noa te mea e pā ana ki a rātou katoa: te kakahu o ngā fret.

He tikanga pakaru ngawari engari he tino kino te pakaru o te fretting. Ka puta ina pakaru te atanga whakapā i ngā nekehanga moroiti, ka tere te pikinga o te ātete hiko, te ngaronga tohu, ā, ka mutu ka pakaru te pūnaha. Hei whakatika i tēnei, me whai huarahi maha-mātauranga tae atu ki te mahi whakarewa matatau, te miihini tika, me te pūtaiao polymer pakari.

🎯 Ngā Hunga Matua me ngā Taupānga

Ngā Kaihoahoa Waka Taumata-1: Ngā Kōwae Whakahaere Mīhini, Ngā Atanga Pūoko, Te Tohatoha Mana.
Te Hokonga Ahumahi: Ngā Mīhini Taumaha, te Aunoatanga CNC, ngā Raina Huihuinga Robotics.
Ngā Kaiwhakauru Rerewē: Ngā Paewhiri Hiko Rori, Ngā Pūnaha Tohu, Ngā Taiepa Rerewē DIN.

Te Mārama ki te Tikanga Whakamau o te Fretting

I te taumata moroiti, ka puta te nekehanga moroiti whanaunga i waenga i ngā mata pa e hono ana te wiri me te huringa wera. Ko tēnei nekehanga, e whakaatu ana i te nuinga o te wā he Te kaha o te 1-50μm, he rawaka hei horoi i ngā paparanga waikura tiaki i runga i ngā konganuku turanga. Ina pāngia te konganuku hou e te hāora, ka tere te waikura. Mā te huringa horoi me te waikura tonu ka hangaia he paparanga ārai o ngā para waikura i te atanga whakapā.

Te Paepae Rahunga: I te kohikohinga o te kiriata waikura, ka piki ake te ātete whakapā (ΔR). I roto i ngā ara iahiko motuka me ngā ara iahiko ahumahi tairongo, he ΔR > 10mΩ e mōhiotia whānuitia ana ko te paepae rahunga, e arahi ana ki ngā hekenga ngaohiko, te wera ā-rohe, me te tuku raraunga pūoko koretake.

1-50μm Te Whānui o te Nekehanga-iti

>10mΩ Paepae Rahunga (ΔR)

150°C Teitei o te Pāmahana o raro i te Ao

Pūtaiao Rauemi: Ngā Whakaotinga Whakapā me ngā Rautaki Whakakikorua

Hei ārai i te waikura o te fretting, he mea nui te whiriwhiri i te rauemi whakapā me te whakakikorua. Ko ngā āhuatanga tribological o te atanga e tohu ana i tōna roa o te huringa teitei, inā koa i roto i ngā taiao raro whenua uaua e mahi ana i te 150°C me te 85% te haumākū (RH).

⚙ He mea whakakikorua ki te tine (3-5μm)

He tino whai hua te whakakikorua tine, ā, he tino pai te tūhonohono. Heoi, ka ngawari te waikura o te tine i raro i te wiri nui. He pai rawa atu mō ngā taiao pūmau, mō ngā tono rānei ka taea e te kaha pa noa te wero i te paparanga waikura tine, kia mau tonu ai te hiri ā-hau.

🔬 Whakakikoruatia ki te koura (0.8-1.5μm)

He konganuku rangatira te koura, arā, kāore e waikura. Mā te kanapa o te koura i runga i te pereti nikara i raro iho ka tino ātete ki te pakaru o te kiri, ā, ka mau tonu te ātete pā iti, pumau hoki mō ngā mano tini o ngā huringa hononga. Koinei te whiringa tino pai mō ngā atanga pūoko ngaohiko iti.

⚡ Paratiuma-Nikara (1.0-2.0μm)

He maha ngā wā ka oti te whakakī ki te koura kanapa, ka tukuna e te Palladium-Nickel (PdNi) te pakeke me te ātete ki te kakahu ki te koura parakore. He pai rawa atu tēnei rautaki whakakikorua paparanga maha mō ngā tono wiri nui e hiahia ana ki ngā huringa hononga roa me te kore e whakararu i te pono o te tohu.

Mā te whakauru i te hangarau whakakikorua tika ka pā tika ki te roa o te hononga o ngā Papa Ara Iahiko Tā (PCB). Hei tauira, ka taea e ngā kaihangarau e rapu ana i ngā otinga waea-ki-papa pakari te tūhura i te Poraka Whakamutunga Tīwiri PCB 301 5.0, e whakamahi ana i ngā whakaotinga whakapā kua arotauhia hei whakarite i te pono mō te wā roa ki te pirau i puta mai i te wiri.

Te Arotau i te Kaha Noa o te Hoapā

Ahakoa ka whakaitihia te waikura e te whakakikorua kounga teitei, ko te pumau miihini e whakawhirinaki ana ki te kaha noa o te pa. He kaha pa o te puna i hangaia kia tino tika - mai i te 1.0 ki te 2.5N mō ia whakapā—me whakatū hei ārai i te nekehanga moroiti me te pupuri tonu i te taurite ergonomic o te kaha whakauru me te kaha tango.

Me whai whakaaro ngā kaihoahoa ki te whakangāwari o te ahotea me te whakahekenga o te kaha pupuri i roto i te wā. I muri i te 500+ huringa hononga, ka hinga ngā rauemi puna kāore i te rawaka, ka whakaiti i te kaha noa i raro i te paepae matua e hiahiatia ana hei pupuri i te hononga hau-kore. Mā te maitai puna kounga teitei (pēnei i te SUS301, 1/2H) ka noho tonu te kaha noa puta noa i te huringa ora o te hua.

Mō ngā tono e hiahia ana kia tere te tāutanga, ātete wiri, e tino taunakihia ana te hangarau pana-roto. Poraka Whakamutunga Waea Pana-roto Rerewē DIN PCT-211 hei tauira mō tēnei arotautanga ā-mīhini, e tuku ana i te kaha piri pumau e ārai kaha ana i te kukume waea me te kakahu wiri i roto i ngā kāpata whakahaere rerewē me ngā kāpata whakahaere ahumahi.

Te Kōwhiringa Rauemi Whare me ngā Āhuatanga Wera

🔥 Ngā Pūmua Mahi-Teitei

Ko te pumau o te āhua o te whare poraka pito ka pā tika ki te whakaritenga me te nekehanga moroiti o ngā hononga. Ka whakamahia e mātou ngā kirihou hangarau matatau kua whakaritea ki ngā kōtaha wera motuhake:
