Kerehanangā taputapu porowhita porowhitaHe momo taputapu piko motuhake ēnei i hangaia hei tuku mana i waenga i ngā pou e whakawhiti ana, i te nuinga o te wā he koki 90 nekehanga. Ko te mea e wehewehe ai te pūnaha Gleason ko tōna āhua niho ahurei me te tikanga hanga, e whakarato ana i te nekehanga maeneene, te kaha taipana teitei, me te mahi mārie. He whānuitia te whakamahinga o ēnei taputapu i roto i ngā tuku waka, ahumahi, me te rererangi, he mea nui te pono me te tika.
I whakawhanakehia te pūnaha Gleason hei whakapai ake i te tika me tengā taputapu whakarara zerolmā te whakauru i tētahi niho piko, porowhita te āhua. Mā tēnei āhua porowhita ka taea te piri haere i waenga i ngā niho, ka whakaitihia te haruru me te wiri, me te tuku hoki i ngā tere hurihuri me te kaha kawenga teitei ake. Ka whakarei ake hoki te hoahoa i te ōwehenga pa me te kaha o te mata, ka whakarite kia pai te tuku mana i raro i ngā kawenga taumaha, hihiri rānei.
Kei roto i ia takirua taputapu porowhita Gleason he pinion me he taputapu honohono, he mea hanga me te āhua ōrite. He tino motuhake te tukanga hanga. Ka tīmata mā te hanga, te whakarewa tika rānei i ngā mea parakore maitai koranu, pērā i te 18CrNiMo7-6, ā, muri iho ka tapahia, ka whakakoi, ka hangaia rānei hei whakaputa i te āhua taputapu tuatahi. Mā ngā tikanga matatau pērā i te miihini 5-tuaka, te whakakoi, me te tapahi mārō ka whakarite kia tino tika te āhua me te whakaotinga mata kua whakapaitia. Whai muri i te maimoatanga wera pērā i te whakakoi (58–60 HRC), ka hurihia, ka hurihia rānei ngā taputapu kia tino pai ai te hononga i waenga i te pinion me te taputapu.
Ko te āhua o ngā taputapu porowhita Gleason e tautuhia ana e ētahi tawhā matua—te koki porowhita, te koki pēhanga, te tawhiti o te kōne piko, me te whānui o te mata. Ka tatauhia ēnei tawhā kia tika ai ngā tauira pa o ngā niho me te tohatoha kawenga. I te wā o te tirotiro whakamutunga, ka manatokohia e ngā taputapu pēnei i te mīhini ine taunga (CMM) me te tātari pa o ngā niho (TCA) kei te tutuki te huinga taputapu i te akomanga tika DIN 6, ISO 1328-1 rānei e hiahiatia ana.
Kei te mahi, ko te porowhita Gleasonngā taputapu pikoHe tino pai te mahi, he pumau hoki ahakoa i raro i ngā āhuatanga uaua. Ka whakarato ngā niho piko i te hononga tonu, ka whakaiti i te kukū o te ahotea me te pakaru. Nā tēnei ka pai mō ngā rerekētanga motuka, ngā pouaka taraka, ngā mīhini taumaha, ngā pūnaha whakatere moana, me ngā taputapu hiko. Hei tāpiri, mā te āheinga ki te whakarite i te āhua o ngā niho me te tawhiti whakairi ka taea e ngā kaihangarau te arotau i te hoahoa mō ngā here taipana, tere, me te wāhi motuhake.

Mā ngā hangarau whakaputa hou, pērā i ngā mīhini tapahi me te huri taputapu CNC, ka whakarite kia rite te kounga me te whakawhitiwhiti. Mā te whakauru i te hoahoa āwhina-rorohiko (CAD) me te whakatauira, ka taea e ngā kaihanga te mahi i te hangarau whakamuri me te whakamātautau mariko i mua i te whakaputanga tuturu. Mā tēnei ka whakaitihia te wā arahi me te utu, me te whakapai ake i te tika me te pono.
Hei whakarāpopototanga, ko ngā taputapu porowhita Gleason he huinga tino pai o te āhuahanga matatau, te kaha o ngā rauemi, me te tika o te hanga. Nā tō rātou kaha ki te tuku i te tuku hiko maeneene, whai hua, me te roa, kua waiho hei wāhanga nui i roto i ngā pūnaha taraiwa hou. Ahakoa e whakamahia ana i roto i ngā rāngai motuka, ahumahi, rererangi rānei, ka mau tonu te hiranga o ēnei taputapu ki te nekehanga me te mahi miihini.
