Te mōhiotanga taketake mō te peera

Hei wāhanga nui o ngā mīhini o nāianei, ngā peera e whakamahia whānuitia ana. E mōhio ana tātou katoa, ā, he iti ake, he iti iho rānei ngā mōhiotanga mōna.

Ngā peerako te tikanga he mowhiti o roto, he mowhiti o waho, he huānga hurihuri me te whare herehere. Mō ngā peera hiri, tāpirihia he hinu whakahinuhinu me ngā hiri (ngā parepare rānei). Koinei te tikanga o ngā peera.

E ai ki ngā āhuatanga mahi o te peera, ka taea te whiriwhiri i ngā momo peera rerekē hei whakapai ake i te mahi a te peera me te whakaroa i te roa o te mahi a te peera. Me whai whakaaro tātou ki ēnei āhuatanga i te wā e whiriwhiri ana i ngā peera:

Kawenga pūtoro

Kawenga tuaka

Ngā whakaritenga RPM

Te rere o te pūtoro

Te rere ā-tuaka

Te pāmahana whakahaere

Ngā whakaritenga haruru

Āhua whakahinuhinu

 

Ko te tauira peera he waehere-mua, he waehere taketake, me te waehere-pou. I te nuinga o te wā, ko te tohu peera ka tohua noa e te tohu taketake. Ko te tauira taketake he wāhanga e toru, ko te waehere momo, ko te waehere rahi me te waehere diameter o roto. Ko te waehere-pou he whakamahi i ngā reta me ngā tau hei tohu i te hanganga, te manawanui me ngā whakaritenga motuhake o te rauemi. Ko te waehere mua e whakamahia ana hei tohu i ngā wāhanga iti o te peera, e tohuhia ana e ngā reta.

 

1. Ingoa waehere taketake

Ka whakamahia te waehere taketake hei tohu i te diameter o roto, te raupapa diameter, te raupapa whānui me te momo peera, tae atu ki te rima mati, penei:

1) Ko te diameter o roto o te peera e tohuhia ana e te mati tuatahi mai i te taha matau o te waehere taketake.

Ko te whānui o roto o te peera me te whānui o roto noa o d=20~480mm he tauwehenga o te 5, ā, ko ēnei mati e rua e tohu ana i te wāhanga o te rahi o te whānui o roto o te peera ina wehea ki te 5, pērā i te 04 ko te tikanga o d=20mm; ko te 12 ko te tikanga o d=60mm me ētahi atu. Mō ngā peera me te whānui o roto o 10mm, 12mm, 15mm me te 17mm, ko ngā waehere whānui o roto ko 00, 01, 02 me te 03. Mō ngā peera he whānui o roto iti iho i te 10mm me te neke atu i te 500mm, kua tohua kētia te tikanga whakaatu whānui o roto, tirohia te GB/T272-93.

 

2) Ko te raupapa diameter o te peera (arā, ko te raupapa o ngā huringa o te diameter o waho me te whānui o te peera me te hanganga ōrite me te diameter o roto ōrite) e tohuhia ana e te mati tuatoru mai i te taha matau o te waehere taketake.

Hei tauira, mō ngā peera radial me ngā peera turaki radial, ko te 0 me te 1 e tohu ana i te raupapa māmā ake; ko te 2 e tohu ana i te raupapa māmā; ko te 3 e tohu ana i te raupapa waenga; ko te 4 e tohu ana i te raupapa taumaha. Ko te whakatairite rahi i waenga i te raupapa e whakaatuhia ana i te ahua i raro nei. Haunga te raupapa māmā ake me te 1, he rite te peera turaki ki te whakaaturanga o te peera radial.

3) Ko te raupapa whānui o te peera (arā, ko te raupapa o ngā huringa o te whānui o te peera me te hanganga ōrite, te diameter o roto me te raupapa diameter) e tohuhia ana e te mati tuawhā mai i te taha matau o te waehere taketake.

Ina whakaritea te raupapa diameter o te raupapa whānui o te Pikitia 13-4 hei raupapa 0 (raupapa noa), kāore e taea te tohu i te waehere raupapa whānui O i roto i te waehere mō te nuinga o ngā peera, engari mō ngā peera roera porowhita me ngā peera roera whakarara, me tohu te waehere raupapa whānui 0. Ko ngā waehere raupapa diameter me ngā waehere raupapa whānui ka kiia ngātahitia he waehere raupapa ine.

 

4) Ko te waehere momo peera e tohuhia ana e te mati tuarima mai i te taha matau o te waehere taketake (mō ngā peera roera porotaka me ngā peera roera ngira, he reta te waehere).

 

2. Waehere Poutapeta

Ko te waehere poutapeta o te peera he mea whakamahi i ngā reta me ngā tau hei tohu i te hanganga, te manawanui me ngā whakaritenga motuhake o te rauemi. He maha ngā ihirangi o ngā waehere poutapeta, ā, anei ētahi ingoa waehere e whakamahia whānuitia ana.

1) Ko te waehere hanganga ā-roto hei tohu i te hanganga ā-roto rerekē o te momo peera kotahi, e tohuhia ana e ngā reta me te waehere taketake. Hei tauira, ko ngā peera pōro whakapā koki me ngā koki whakapā o te 15°, 25° me te 40° e tohuhia ana e C, AC me B hei tohu i te rerekētanga o te hanganga ā-roto.

2) Kua wehea te taumata manawanui o te peera kia 2 ngā taumata, 4 ngā taumata, 5 ngā taumata, 6 ngā taumata, 6 ngā taumata 6X me te 0 ngā taumata, e 6 katoa ngā taumata, mai i te teitei ki te iti, ā, ko ō rātou waehere ko /PZ, /P4, /PS, /P6, /P6X me /PO. I roto i ngā akomanga manawanui, ko te akomanga 6X e pā ana ki ngā peera roera whakarara anake; ko te taumata 0 he taumata noa, kāore i tohua i roto i te waehere peera wira.

3) Ko te raupapa āputa porowhita o te peera e whakamahia whānuitia ana kua wehea kia 1 rōpū, 2 rōpū, 0 rōpū, 3 rōpū, 4 rōpū me te 5 rōpū, e 6 katoa ngā rōpū, ā, ko te āputa porowhita mai i te iti ki te rahi. Ko te āputa rōpū o he rōpū āputa e whakamahia whānuitia ana, kāore i tohua i roto i te waehere peera, ā, ko te toenga o ngā rōpū āputa e tohuhia ana e /CI, /CZ, /C3, /C4 me /CS i roto i te waehere peera.

 

3. Whakatakotoria i mua i te waehere

Ko te tohu kupumatua o te peera e whakamahia ana hei tohu i ngā wāhanga iti o te peera, e tohua ana e ngā reta. Hei tauira, ko te L e whakamahia ana hei tohu i te mowhiti wehe o te peera wehe; ko te K e tohu ana i ngā huānga hurihuri me ngā wāhanga whare herehere o te peera, me ētahi atu.

 

He maha ngā momo peera hurihuri i roto i ngā mahi whaihua, ā, he uaua ake hoki ngā waehere peera e rite ana. Ko te waehere kua whakaurua i runga ake nei te wāhanga tino taketake me te wāhanga e whakamahia whānuitia ana o te waehere peera, ā, ka taea e koe te tautuhi me te tirotiro i te peera e whakamahia whānuitia ana mēnā e mōhio ana koe ki tēnei wāhanga o te waehere. Mō te tikanga waehere taipitopito o ngā peera hurihuri, tirohia te GBT272.
