Ko ngā taputapu he toa wahangu, he toa nui o te ao hou. Mai i te mahi uaua o te tuku hiko o te waka ki te mana nui o te tāhū hau, he mea nui ēnei wāhanga niho ki te tuku hiko miihini. Mō ngā rautau, ko te hanga taputapu he whai i te tika me te whai hua, e whakahaerehia ana e ngā tukanga kua whakapumautia pēnei i te hobbing, te shaping, me te broaching. Heoi, ko ngā tono tonu o te ahumahi hou—mō ngā rahinga whakaputa nui ake, te whai hua nui ake o te utu, me te whakauru wāhanga pakari ake—kua akiaki i te whanaketanga o tētahi hangarau whakarerekē:Te Whakatere Mana.

Te Mātāpono Mīhini o te Power Skiving

Ko te mahi "power skiving" he tukanga tapahi whakaputa uri tonu e whakakotahi ana i te hurihanga tere-teitei o te hobbing me te whakaritenga taputapu-mahi o te hanga taputapu. He tukanga "hurihuri" uaua, e huri ana te tapahi niho maha me te taputapu papa i roto i te nekehanga honohono tika.

Ko te āhuatanga matua o te power skiving ko tekoki whakawhiti tuaka (Σ). Kāore i rite ki te hobbing (kei te koki 90-tohu te toki o te taputapu me te mea mahi, ka wehea e te koki helix) me te shaping (kei te whakarara ngā toki), ka mahi te power skiving me te whakatakoto i ngā toki o te taputapu me te mea mahi ki tētahi koki motuhake, kāore e whakarara, kāore hoki e whakawhiti. Ko tēnei koki te mea matua e āhei ai te tukanga.

Mā tēnei koki i ata tatauhia, ka hangaia he tere whanaunga motuhake (paheke) i waenganui i ngā taha tapahi o te taputapu me ngā taha o te mea mahi. I te hurihuri o te taputapu me te mea tapahi i ngā tere teitei, ka puta te mahi tapahi i tēnei tere paheke. Ko te taputapu tapahi, he rite ki te kaitapahi āhua engari he koki porowhita tōna, ka "huki" i te rauemi mai i te mea tapahi i ia haerenga o te taha tapahi, ka puta tonu te āhua niho kōpikopiko i te hurihuri o ngā wāhanga e rua.

Te Whakamahi Utauta: Te Ngākau o te Tukanga

He taputapu tino uaua, he taputapu motuhake hoki te taputapu tapahi mō te power skiving. He mea hanga i te nuinga o te wā mai i te carbide pania totoka kia tino pakari ai, kia ātete ai hoki ki te kakahu, i te maitai tere-teitei (HSS) rānei o te paura whakarewa mahi-teitei (PM). Ko te hoahoa o te taputapu—tae atu ki tōna koki porowhita, te koki rake, me te kōtaha—ka tatauhia mō te tauira kinematic o te mīhini me te āhua tika o te taputapu ūnga. He mea nui tēnei uauatanga motuhake ki te taputapu i roto i te utu whānui me te whakatakotoranga o te tukanga.

Ngā Painga me ngā Huakore o te Power Skiving

Pērā i ngā tukanga hanga katoa, he rerekē ngā painga o te power skiving.

Ngā Painga:

Te Hua Tino Pai: He tere ake (3-10 ngā wā) i te hanga taputapu, ā, he tino whakataetae ki te hanga oumu. Mō ngā taputapu o roto, koinei te tikanga tino pai e wātea ana.

Ngāwari Kore e ōrite: Ka taea e te tukanga te miihini i ngā taputapu o roto, o waho hoki, tae atu ki ngā splines, ngā taputapu helical, me ngā taputapu spur i runga i te mīhini kotahi.

Te Pūkenga "Oti-i-te-Kotahi": Ka taea e ia te mahi i te tārai, te whakaoti-haurua, me te whakaoti i roto i te whakatakotoranga kotahi. Ka taea hoki e ia te whakamārō, te miihini rānei i ngā taputapu i muri i te maimoatanga wera, ka kore ai e hiahiatia he mahi huri i muri mai.

Kounga Teitei: Ina mahia i runga i tētahi mīhini hou, pakari, ka taea e te power skiving te whakaputa i ngā taputapu tino tika (hei tauira, AGMA 10-11, DIN 6-7) me ngā whakaotinga mata tino pai.

E Whakatau Ana i ngā Āhuahanga Uaua: He mea tino pai mō ngā wāhanga he iti te āputa taputapu, pērā i ngā taputapu he pakihiwi, he flange rānei, e kore ai e taea te oma i te oumu. He wero noa tēnei i roto i ngā hoahoa tuku hiko kiato.

Ngā ngoikoretanga:

Te Utu Pūtea Mīhini Nui: E hiahiatia ana he mīhini CNC tuaka-5 (neke atu rānei) tino matatau, pakari, ā, he pumau ki te wera, me te tukutahitanga hiko tino pai, he haumitanga nui tēnei.

Tukanga me ngā Utauta Uaua: He tino uaua ngā mahi kinematic. Me whakamahi pūmanawa whakatauira matatau hei whakamahere tukanga hei tatau i ngā ara taputapu me te karo i ngā tukinga. He utu nui ngā taputapu, ā, he motuhake ki te tono.

Te Tairongo o te Tatūnga: He tino tairongo te tukanga ki te tatūnga tika, inā koa te koki whakawhiti o te tuaka. Ka pā kino te kore taunga ki te roa o te taputapu me te kounga o te wāhanga.

Te Whakahaere Maramara: Ka raru pea te whakahaere maramara i te tango tere-nui i ngā rahinga nui o ngā rauemi, inā koa i te wā e miihini ana i ngā taputapu hōhonu o roto ka taea te whakakīkī i ngā maramara.

Ngā horopaki tono

Ehara te power skiving i te whakakapinga whānui mō ngā tukanga taputapu katoa, engari he otinga matua i roto i ngā wāhanga motuhake, nui te uara, e ahu mai ana i te hanga papatipu.

Ahumahi Waka: Koinei te mea tino nui rawa atu. He whānuitia te whakamahinga o tēnei tukanga mō te hanga i ngā wāhanga tuku ā-roto pērā i ngā taputapu mowhiti, ngā taputapu aorangi, me ngā tinana mamau kua whakapikohia. He mea tino nui tōna kaha ki te hanga taputapu ā-roto me ngā whakapiko uaua i roto i te tere me te tino tika, mō ngā tuku waka aunoa hou, kiato me ngā tuku waka hiko (EV).

Rererangi: Whakamahia ai mō te hanga i ngā splines me ngā taputapu pūnaha whakaoho, he mea nui te pono me ngā hoahoa uaua, māmā hoki.

Mīhini Ahumahi: He mea tino pai mō te hanga i ngā wāhanga pēnei i ngā taputapu papu, ngā hononga, me ētahi atu toki whatu e mea nui ana te hua me te tika.

Ko te mea tino pai mō te power skiving he wāhanga rahinga-waenga ki te-rahi, inā koa he taputapu o roto, he taputapu rānei he pakihiwi pokanoa, ina taea e ngā penapena wā huringa te whakamana i te haumitanga tuatahi nui ki ngā mīhini me ngā taputapu.

Whakamutunga

Kua angitu te mahi power skiving i te peke atu i tētahi ariā ariā 100-tau te pakeke ki tētahi whare hanga hou. Mā te whakakotahi i te tere o te hobbing me te ngāwari o te hanga, kua whakakīia he āputa nui i roto i te hanga taputapu. Ka tukuna e ia he otinga tino pai mō te hanga nui o ngā taputapu o roto me ngā wāhanga uaua, e whakatairanga ana i te whai huatanga me te whakahohe i te whakatupuranga hou o ngā pūnaha miihini kiato, kaha-kaha. I te haere tonu o te whanaketanga o te hangarau taputapu mīhini, te pūmanawa whakaata, me ngā hoahoa taputapu tapahi, ka whānui haere te whakamahinga o te power skiving, ka whakaū ake i tana tūranga hei kaha hurihuri i roto i te hanga taputapu.
