He aha te tukanga whakaotinga o te peera?

Ehara i te mea ko te tukanga whakaotinga-whakapaipai anake e whakamahia ana i roto i te umanga peera, engari i roto hoki i ngā miihini, ā, kua tīmata hoki ētahi atu mīhini me ngā taputapu tika ki te whakamahi i tēnei tukanga.

He aha te tino tika o te peera?

Ko te superfinishing bearings he tikanga whakaeneene he nekehanga whāngai hei whakatutuki i te huri-iti.

Ko te mata i mua i te whakaotinga, he mea huri me te huri tika te nuinga. Ina koa, e pā ana ki tētahi tikanga tukatuka whakangawari e iti ana te pēhanga ki runga i te mea mahi me te taputapu whakakoi pai (kohatu hinu) i raro i ngā tikanga whakahinuhinu me te whakamatao pai, ā, ka tere, ka poto hoki te nekehanga hurihuri i runga i te mea mahi e hurihuri ana i tētahi tere i te ahunga hurihuri poutū maroke o te mea mahi.

He aha te mahi a te superfinishing bearing?

I roto i te tukanga hanga o ngā peera hurihuri, ko te whakaotinga nui te tukanga whakamutunga o te tukatuka mowhiti peera, he mea nui ki te whakaiti, ki te whakakore rānei i te peka porowhita i mahue mai i te tukatuka huri, te whakatika i te hapa āhua o te awaawa, te whakamahine i tōna taratara mata, te whakapai ake i ngā āhuatanga ā-tinana me ngā āhuatanga ā-pūkaha o te mata, te whakaiti i te wiri me te haruru o te peera, me te whakapai ake i te mahi a te peera.

Ka taea te whakatinana i roto i ngā āhuatanga e toru e whai ake nei

1. Ka taea e ia te whakaiti i te ngaru. I roto i te tukanga whakaoti-whakaoti, kia mau tonu ai te mahi a te kōhatu hinu ki te tihi o te ngaru, ā, kia kore ai e pā ki te awaawa, ko te pewa o te kōhatu hinu e pā ana ki te mea mahi he ≥ te roangaru o te ngaru i runga i te mata o te mea mahi, kia nui ake ai te pēhanga pā o te tihi, kia tangohia ai te tihi pūkohu, kia whakaitihia ai te ngaru.

2. Whakapai ake i te hapa awaawa o te ara reihi pōro. Ka taea e te whakaotinga-tino pai te whakapai ake i te hapa awaawa o te 30% o ngā ara reihi.

3. Ka taea e ia te whakaputa i te ahotea pēhi i runga i te mata o te huri tino pai. I roto i te tukanga whakaoti-whakaoti, ka puta te nuinga o te ahua kirihou makariri, kia puta ai te ahotea pēhi toenga i runga i te mata o te mea mahi i muri i te whakaoti-whakaoti.

4. Ka taea te whakanui ake i te horahanga pa o te mata mahi o te ferrule. I muri i te whakaotinga-nui, ka taea te whakanui ake i te horahanga pa o te mata mahi o te ferrule mai i te 15% ~ 40% i muri i te huri ki te 80% ~ 95%.

Te tukanga whakaotinga o te peera:

1. Te tapahi i ngā peera

Ina pā te mata o te kōhatu huri ki te tihi pūkohu o te mata o te ara rere taratara, nā te iti o te horahanga pā me te kaha nui ki te horahanga kotahi, i raro i te mahi a tētahi pēhanga, ka tukuna tuatahitia te kōhatu huri ki te mahi "tapahi whakamuri" o te mea mahi peera, kia taka ai tētahi wāhanga o ngā matūriki whakakoi i runga i te mata o te kōhatu huri, kia pakaru ai, ka kitea ētahi kōhatu whakakoi koi hou me ngā taha tapahi. I taua wā anō, ka tapahia teretia te puku o te mata o te mea mahi peera, ā, ka tangohia te tihi me te paparanga pirau huri i runga i te mata o te mea mahi peera mā te tapahi me te tapahi whakamuri. Ka kiia tēnei wāhanga ko te wāhanga tapahi, ā, i tēnei wāhanga ka tangohia te nuinga o te toenga whakarewa.

2. Te tapahi haurua o ngā peera

I te haere tonu o te mahi miihini, ka āta whakamāeneenehia te mata o te mea mahi whāriki. I tēnei wā, ka piki ake te horahanga pa i waenga i te kōhatu huri me te mata o te mea mahi, ka heke te pēhanga mō ia horahanga, ka heke te hohonutanga tapahi, ā, ka heke te kaha tapahi. I taua wā anō, ka āraia ngā pūwero i runga i te mata o te kōhatu huri, ā, kei roto te kōhatu huri i te āhua tapahi-haurua. E mōhiotia ana tēnei wāhanga ko te wāhanga tapahi-haurua o te whakaotinga whāriki, ka mārama ake ngā tohu tapahi i runga i te mata o te mea mahi whāriki, ā, ka pōuri ake te kanapa.

3. Wāhanga whakaoti

Ka taea te wehewehe i tēnei wāhanga kia rua ngā taahiraa: ko tētahi ko te wāhanga whakawhiti huri; ko te tuarua ko te wāhanga huri i muri i te whakamutu i te tapahi.

Wāhanga whakawhiti huri:

Ka whakakoitia te kakano whakakoi i a ia anō, ka whakamāeneenetia te taha o te kakano whakakoi, ka tīmata te whakauru i te waikura maramara ki roto i te āputa o te kōhatu hinu, ka āraia e te paura whakakoi ngā pūwero o te kōhatu hinu, kia kore ai e taea te tapahi ngoikore i te kakano whakakoi, me te haere tahi me te whakaputa me te huri, kātahi ka tere te whakaiti i te taratara o te mata o te mea mahi, ā, ka piri te mata o te kōhatu hinu ki te waikura maramara pango.

Whakamutua te wāhanga huri tapahi:

He tino maeneene te waku o te kōhatu hinu me te mea mahi, kua tino piki ake te horahanga pa, kua heke te pēhanga, kua taea e te kakano whakakoi te uru ki roto i te kiriata hinu me te pa ki te mea mahi, ina taurite te pēhanga o te kiriata hinu o te mata o te peera ki te pēhanga o te kōhatu hinu, ka mānu te kōhatu hinu. I te wā e hangaia ana he kiriata hinu, kāore he pānga tapahi. He mea motuhake tēnei wāhanga ki te whakaotinga-ā-ringa.
