Te tohu o te peera me tōna tikanga

 

Inaianei tete whārikiKa piki haere te tauira i runga i ngā hiahia rerekē o te iwi o nāianei, ā, kua tino whanake te whatunga, kua tere hoki te tuku mōhiohio, ā, he māmā ake te mōhio ki te tauira peera. Muri iho, ka whakamōhio atu mātou ki a koe ki te waehere taketake, te waehere-pou, te waehere-mua me ētahi atu mōhiotanga e pā ana ki te peera.

 

Te whāngaite tohu me tōna tikanga Ngā wāhanga tohu peera

 

Tete whārikiKo te tikanga, he waehere-mua, he waehere taketake, me te waehere-poutāpeta o te tauira. I te nuinga o te wā, ko te tohu o te peera ka tohua noa e te tohu taketake. Ko te tikanga, e toru ngā wāhanga o te tauira taketake, ko te waehere momo, ko te waehere rahi, me te waehere diameter o roto. Ko te waehere-poutāpeta 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 kupumatua e whakamahia ana hei tohu i ngā wāhanga iti o te peera, e tohuhia ana e ngā reta.

 

Tikanga Whakatakotoranga Whānui mō te Peera Whānui (Peera Hurihuri)

 

Kua wehea kia rua ngā wāhanga: te waehere-mua, te waehere taketake me te waehere-pou.

 

1. Ingoa waehere taketake

 

(Waehere momo, waehere rahi, waehere diameter o roto [2 mati])

 

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 diameter o roto o te peera me te diameter o roto noa o d=20~480mm he maha o te 5, ā, ko ēnei mati e rua e tohu ana i te haurua o te rahi diameter o roto o te peera ina wehea ki te 5, pērā i te 04 ko te tikanga d=20mm; 12 ko te tikanga d=60mm, me ētahi atu. Mō ngā peera me te diameter o roto o 10mm, 12mm, 15mm me te 17mm, ko ngā waehere diameter o roto ko 00, 01, 02 me te 03. Mō ngā peera he diameter o roto iti iho i te 10mm me te neke atu i te 500mm, ko te tikanga whakaatu i te diameter o roto kua tohua kētia, 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 pana radial me te radial, ko te 0 me te 1 e tohu ana i te raupapa māmā tāpiri; 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 whakataurite rahi i waenga i te raupapa e whakaatuhia ana i te ahua i raro nei. Ko ngā peera pana engari ko te 1 hei tohu i te raupapa māmā, he ōrite te toenga me ngā 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 whakarārangihia te whakataurite o te raupapa diameter o te raupapa whānui i 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 e kiia ngātahitia ana ko ngā 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 i 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 GBT272-93.
