He aha te Porowhita Porowhita i roto i ngā Taputapu?

I roto i te hangarau taputapu,papa porowhitaKo tētahi o ngā inenga tino taketake e whakamahia ana hei whakaahua i te mokowā o ngā niho huri noa i te taputapu. Ka pā tika ki te hononga o ngā taputapu, te tuku nekehanga, me te pupuri i te tukutahitanga i roto i ngā pūnaha tuku mana. He mea nui te mārama ki te piko porowhita mō te hoahoa taputapu tika me te hototahi i waenga i ngā taputapu e hono ana.

Te Whakamāramatanga o te Pitch Porowhita

Ko te teitei porowhita (p) e tautuhia ana ko te tawhiti i waenga i tētahi pūwāhi i runga i tētahi niho taputapu me te pūwāhi e rite ana i runga i te niho e whai ake nei, e inehia ana i te porowhita teitei.
Teporowhita papahe porowhita tohutoro pohewa e tohu ana i te pūwāhi e pā ana ki ngā taputapu honohono e rua.

Kia tika ai te hono o ngā taputapu e rua, me ōrite te teitei o ō rāua porowhita, kia pai ai te uru o ia niho o tētahi taputapu ki te āputa i waenganui i ngā niho o tētahi atu.

Tātai me te Tātaitanga

Ko te tātai mō te tatau i te teitei porowhita e ahu mai ana i te porowhita teitei me te maha o ngā niho: p=πd​/N

Kei hea:

•  p = Te teitei porowhita

• d = Te whānui o te papa (te whānui o te porowhita papa)

• N = Te maha o ngā niho

E whakaatu ana tēnei tātai ko te teitei porowhita e whakawhirinaki ana ki te rahi o te taputapu me te maha o ngā niho — ka nui ake te tawhiti teitei mēnā he nui ake ngā taputapu, he iti ake rānei ngā niho.

Te Hononga i waenganui i te Pitch Porowhita me te Pitch Diametral

He hononga tata te teitei porowhita ki tētahi atu ine taputapu noa e mōhiotia ana ko te teitei diametral (P), e whakamahia whānuitia ana i roto i te pūnaha imperial.

Ko te teitei o te piko e tohu ana i te maha o ngā niho mō ia inihi o te whānui o te piko, ā, ko te hononga pāngarau o ngā mea e rua penei: p=π​/p

Mā tēnei hononga ka taea e ngā kaihangarau te huri ngāwari i waenga i ngā pūnaha taputapu e hangai ana ki te ine (te piki porowhita) me te pūnaha taputapu e hangai ana ki te imepera (te piki diametral).

Āhea te Whakamahi i te Pitch Porowhita

Ahakoa he paerewa te piko porowhita i roto i te maha o ngā tono taputapu whānui, he painga anō hoki tō te piko porowhita i roto i ngā take motuhake:

1. Ngā Pūnaha Nekehanga Raina (Wāhanga me te Pinion):
He pai rawa te piko porowhita mō ngā pūnaha whatanga me te pinion, ka hurihia te nekehanga hurihuri hei nekehanga rārangi. Mā te whakamahi i te piko porowhita ka māmā ake te taupū me te tūnga, nā te mea e rite ana ia hurihanga ki tētahi tawhiti rārangi pumau.
2. Ngā Taputapu Whānui-Diameter:
Mō ngā taputapu nunui, ka taea e te teitei porowhita te ine tika i te tawhiti o ngā niho, kia māmā ake ai te whakamārama atu i te teitei diametral.
3. Ngā Hoahoa e Hangai ana ki te Ine:
I roto i ngā pūnaha hangarau ine, ko te teitei porowhita te ine e pai ana mō te ine, e whakarato ana i te ōritetanga o te rahi me ngā tataunga taputapu.

Ko te piko porowhita he tawhā matua i roto i te āhuahanga taputapu, e whakatau ana i te tawhiti o ngā niho me te maeneene o te hononga o ngā taputapu e rua. Mā te whakahaere tika o tēnei ine ka taea te whakawhiti nekehanga pai, te iti o te kakahu, me te mahi pono puta noa i ngā pūnaha miihini.

I Belon Gear, he tohunga mātou ki te hanga taputapu tino tika me te āhua niho kua arotauhia—kia whakarite kia rite te piko porowhita me te mahi whatunga tino pai mō ngā tono i roto iwaka, karetao, me ngā mīhini ahumahi.
