He aha te Porowhita Pitch i roto i ngā Taputapu?

I roto i te hangarau taputapu, ko te porowhita piko, e mōhiotia ana ko te porowhita tohutoro, tētahi o ngā ariā tino nui hei tautuhi i te hononga o ngā taputapu e rua, me te tuku nekehanga. Koia te porowhita whakaaro e tohu ana i te pūwāhi whakapā whai hua i waenga i ngā taputapu e hono ana, kia pai ai te tuku mana, kia tika ai hoki.

Whakamāramatanga me te Tikanga

Ko te porowhita pitch he porowhita whakaaro e hurihuri ana, kāore e paheke me te porowhita pitch o tētahi atu taputapu i roto i te mata. Ko te diameter o tēnei porowhita e mōhiotia ana ko te diameter pitch, ā, māna e whakatau te rahi o te taputapu, te ōwehenga tere, me te tawhiti pokapū ina honoa ki tētahi atu taputapu.

Kei tēnei porowhita te:

• He rite te matotoru o te niho ki te wāhi o te niho,

• He pumau te ōwehenga tere i waenga i ngā taputapu,

• Ā, ka puta he nekehanga hurihuri parakore (kāore he reti).

I roto i te pāngarau, e pā ana te whānui o te papa (Dp) ki te kōwae (m) me te maha o ngā niho (z) mā:

Dp = m × z

Nā tēnei whārite ka waiho te porowhita teitei hei tohutoro matua mō ngā tātaitanga hoahoa taputapu katoa.

Te Tūranga me te Hiranga o te Porowhita Whakataetae

Teporowhita papae tautuhi ana i teāhuahanga me te mahio te taputapu katoa. Ka taea te whakarāpopoto i tōna hiranga penei:

Whakatau i te ōwehenga taputapu
Ko te ōwehenga o ngā diameter pitch i waenga i ngā taputapu e rua ka homai te ōwehenga tere o te pūnaha. Hei tauira, mēnā he rua te diameter pitch o te Taputapu A i te Taputapu B, ka rua te tere o te hurihuri o te Taputapu B.
Te Tawhiti o te Pokapū Mana
Ko te tapeke o ngā rādiusi porowhita pitch o ngā taputapu whatunga e rua e whakatau ana i te tawhiti pokapū i waenga i ō rāua pou—he mea nui i roto i te hoahoa me te whakaritenga o te pouaka miihini.
Pūtake mō te Hoahoa Kōtaha Niho
Ka puta te kōtaha niho involute mai i te porowhita turanga, e ahu mai ana i te porowhita pitch. Nō reira, ka pā tika ki te maeneene me te mārie o te hononga o ngā taputapu.
Ka whakarite kia maeneene te tuku hiko
Ina hono ngā taputapu ki ō rātou porowhita teitei, ka tukuna te nekehanga me te tere koki ōrite, ka whakaiti i te wiri, te haruru, me te kakahu.

Porowhita Pitch i roto i te Hanga Taputapu

I roto i te mahi whakaputa, kāore e taea te ine ā-tinana i te porowhita pitch nā te mea he tohutoro pakiwaitara noa iho. Heoi, ka whakamahia e ngā kaihanga taputapu tika pērā i a Belon Gear ngā pūnaha ine taputapu CNC matatau me te tirotiro 3D hei whakarite kia mau tonu ngā āhuatanga katoa e pā ana ki te porowhita pitch. Mā tēnei ka whakamanahia te mahi whatunga tika puta noa i ngā tono pērā i awakangā pouaka miihini, ngā karetao ahumahi, me ngā mīhini mahi taumaha.
