Mō te whakanui ake i te whai huatanga me te roa o te ora o ō pūnaha mīhini, he mea nui te whiriwhiri i ngā porotiti mekameka. Me ruku tātou ki ngā āhuatanga matua o ngā rauemi, ngā rahinga, ngā hanganga, me te tiaki hei whakatairanga i ō mahi ki ngā taumata hou.
Kōwhiringa RauemiIna tae ki te whakapai ake i ō pūnaha mīhini, he mea nui te whiriwhiri i ngā rauemi o te mekameka porotiti. Me whakarite kia rawaka te kaha o ngā niho o ō porotiti ki te ngenge pa, me te ātete ki te kakahu. Koia te take he pai te whiriwhiri i te maitai waro kounga teitei, pērā i te maitai 45. Mō aua tono nui, whakaarohia te whakapai ake ki ngā maitai koranu pērā i te 40Cr, 35SiMn rānei hei whakapai ake i te mahi.
Ko te nuinga o ngā niho pītiti ka whakamahanahia kia eke ki te pakeketanga o te mata o te 40 ki te 60 HRC, kia taea ai e rātou te tu atu i ngā uauatanga o te mahi. He mea nui kia mōhio ko ngā pītiti iti ake ka hono pinepine atu i ō rātou hoa nunui, ā, he nui ake ngā pānga ka pā mai. Nō reira, me pai ake ngā rauemi e whakamahia ana mō ngā pītiti iti i ērā e whakamahia ana mō ngā mea nunui.
Mō ngā porotiti e hiahia ana ki te tu atu ki ngā kawenga ru, he kōwhiringa pai te maitai waro-iti. I tētahi atu taha, he pai te maitai whakarewa mō ngā porotiti e pāngia ana e te pakaru engari kāore e pāngia e ngā wiri pānga kino. Mena he kaha teitei me te ātete pakaru tō tono, ko te maitai koranu te huarahi hei whiriwhiri.
Mā te haumi ki ngā rauemi tika mō ō porotiti mekameka, ka roa ake te ora o ō rātou mahi, ā, ka piki ake anō hoki te whai huatanga o ō pūnaha mīhini. Kaua e whakaiti i te kounga—whiriwhiria ma te whakaaro nui, kia kite ai koe i te pikinga o tō mahi!
Ngā Ahu Matua me ngā Kōwhiringa Hanganga
He mea nui te mārama ki ngā ine matua o ō porotiti mō te mahi tino pai. Ko ngā ine matua ko te maha o ngā niho, te whānui o te porowhita piko, te whānui o waho, te whānui o te pakiaka, te teitei o te niho i runga ake i te porowhita piko, me te whānui o te niho. Ko te porowhita piko te porowhita kei reira te pokapū o ngā pine mekameka, e wehea ōritetia ana e te piko o te mekameka.E whakaaturia ana i raro nei:
He maha ngā āhua hanganga o ngā sprocket, tae atu ki ngā momo totoka, ngā momo poka, ngā momo whakarewa, me ngā momo huihui. I runga i te rahi, ka taea e koe te whiriwhiri i te hanganga e tika ana: ka taea e ngā sprocket iti te totoka, he maha ngā wā ka whakamahia e ngā sprocket waenga te hoahoa poka, ā, ko ngā sprocket nui te whānui e whakakotahi ana i ngā rauemi rerekē mō te mowhiti niho me te matua, e honoa ana mā te whakarewa, te whakapiri rānei. Mō ngā tauira motuhake, tirohia a Goodwill'spūwerongā rārangi pukapuka.
Te Hoahoa Niho: Te Ngākau o te Whai Hua
He nui te pānga o te maha o ngā niho i runga i te sprocket ki te maeneene o te tuku me te roa o te ora. He mea nui kia whiriwhiria he maha tika o ngā niho—kaua e nui rawa, kaua hoki e iti rawa. Ka taea e te nui rawa o ngā niho te whakapoto i te roa o te ora o te mekameka, engari ka taea e te iti rawa te arahi ki te kore taurite me te pikinga o ngā kawenga hihiri. Hei whakaiti i ēnei raruraru, he mea tika kia whakawhāitihia te maha iti rawa o ngā niho i runga i ngā sprocket iti, e whakatakotoria ana ki te Zmin ≥ 9. Ka taea te whiriwhiri i te maha o ngā niho i runga i ngā sprocket iti (Z1) i runga i te tere o te mekameka, kātahi ka taea te whakatau i te maha o ngā niho i runga i te sprocket nui (Z2) mā te whakamahi i te ōwehenga tuku (Z2 = iZ). Mō te kakahu ōrite, me tau tauhou ngā niho sprocket.
Tahora Puku Mekameka Tino Pai
He rite te hiranga o te tahora o tō puku mekameka ki ngā wāhanga tonu. Kei raro nei te tahora noa o te puku mekameka
Tahora Whakapae: Me whakarite kia rite te rārangi hurihuri o ngā porotiti e rua ki roto i te rārangi poutū kotahi, kia whakarara hoki ō rāua tuaka hei ārai i te wetewete o te mekameka me te pakaru rerekē.
Tahora Piko: Kia iti rawa te koki i waenganui i ngā rārangi pokapū o ngā pīrori e rua me te rārangi whakapae, kia iti iho i te 45° te pai, kia kore ai e ngoikore te hononga o te pīrori o raro.
Tahora Poutū: Kaua e waiho ngā raina pokapū o ngā pīrere e rua ki te koki 90°; engari, me whakawhāiti paku ngā pīrere o runga me o raro ki te taha kotahi.
Te Tūnga o te Mekameka: Whakanohoia te taha piri o te mekameka ki runga, me te taha ngoikore ki raro hei ārai i te piko rawa, ka raru pea ngā niho o te pīkau.
Te Whakapūmau mō te Mahi Tino Pai
He mea nui te whakatōtika tika o te mekameka hei ārai i te totohu nui, ka kore ai e pai te hononga me te wiri. Ina neke atu te koki i waenga i ngā tuaka o ngā porotiti e rua i te 60°, ka whakamahia he taputapu whakatōtika.
He maha ngā tikanga mō te whakatōtō, ko te mea tino noa ko te whakarite i te tawhiti pokapū me te whakamahi i ngā taputapu whakatōtō. Mena ka taea te whakarite i te tawhiti pokapū, ka taea e koe te whakarerekē kia tutuki ai te tōtō e hiahiatia ana. Ki te kore, ka taea te tāpiri i tētahi wira whakatōtō hei whakarite i te tōtō. Me whakanoho tēnei wira ki te taha ngoikore o te porotiti iti, ā, me rite tōna whānui ki te whānui o te porotiti iti.
Te Hiranga o te Whakahinuhinu
He mea nui te whakahinuhinu mō te mahi tino pai o ngā puku mekameka, inā koa i ngā mahi tere me ngā mahi taumaha. Mā te whakahinuhinu tika ka whakaitihia te pakaru, ka whakaitihia ngā pānga, ka whakanui ake i te kaha kawenga, ā, ka roa ake te roa o te ora o te mekameka. Nō reira, he mea nui kia whiriwhiria te tikanga whakahinuhinu me te momo whakahinuhinu tika kia pai ai te mahi.
Ngā Tikanga Whakahinuhinu:
Te Whakahinuhinu ā-Ringa Auau: Ko tēnei tikanga he whakamahi i tētahi kēne hinu, i tētahi paraihe rānei hei pani i te hinu ki ngā āputa i waenganui i ngā pereti hononga o roto, o waho hoki i te taha ngoikore o te mekameka. E taunakihia ana kia mahia tēnei mahi kotahi i ia nekehanga. He pai tēnei tikanga mō ngā taraiwa kore-tino nui me ngā tere mekameka o v ≤ 4 m/s.
Te Whakahinuhinu Whāngai Hinu Maturuturu: He anga waho māmā tēnei pūnaha, ka maturuturuhia te hinu ki roto i ngā āputa i waenganui i ngā pereti hononga o roto me waho i te taha ngoikore mā roto i te kapu hinu me te paipa. Mō ngā mekameka rarangi kotahi, ko te tere tuku hinu he 5-20 maturuturunga ia meneti, me te uara mōrahi e whakamahia ana i ngā tere teitei ake. He tika tēnei tikanga mō ngā taraiwa me ngā tere mekameka o v ≤ 10 m/s.
Te Whakahinuhinu i te Kaukau Hinu: I tēnei tikanga, mā te anga o waho kāore e turuturu ka taea te mekameka te haere mā roto i tētahi puna hinu kua hiritia. Me tūpato kia kaua e rumakina rawa te mekameka ki roto, nā te mea ka nui rawa te rumakina ka ngaro te hinu nā te whakaohooho, ā, ka wera rawa te hinu, ka pirau. Ko te hohonutanga rumakina o te 6-12 mm te tikanga e taunakihia ana, ā, he pai tēnei tikanga mō ngā taraiwa me ngā tere mekameka o te v = 6-12 m/s.
Te Whakahinuhinu i te Whāngai Hinu Tauhiu: Ka whakamahia e tēnei tikanga he ipu hiri, ka tauhiuhia te hinu ki runga e te pereti tauhiu. Kātahi ka tukuna te hinu ki te mekameka mā te taputapu kohikohi hinu i runga i te anga. Me pupuri te hohonutanga o te pereti tauhiu ki te 12-15 mm, ā, me neke atu te tere o te pereti tauhiu ki te 3 m/s kia pai ai te whakahinuhinu.
Te Whakahinuhinu Pēhanga: I tēnei tikanga matatau, ka rehuhia te hinu ki runga i te mekameka mā te whakamahi i tētahi papu hinu, me te whakanoho i te pūwero ki te wāhi e uru ai te mekameka. Ehara i te mea ka whakahinuhinu noa te hinu e rere ana, engari ka whakarato hoki i te pānga whakamatao. Ka taea te whakatau i te tuku hinu mō ia pūwero i runga i te nekehanga me te tere o te mekameka mā te tirotiro i ngā pukapuka e tika ana, kia pai ai tēnei tikanga mō ngā taraiwa mana-teitei me ngā tere mekameka o te v ≥ 8 m/s.
Hei whakatutuki i te mahi tino pai me te whai hua o ō pūnaha mīhini, he mea nui kia mārama koe ki ngā āhuatanga nui o te whiriwhiri me te tiaki i ngā porotiti mekameka. Kaua e waiho mā te tūponotanga te angitu o ō mīhini - me whakatau whai whakaaro kia puta ai he hua pumau!
Ko te whiriwhiri i ngā rauemi tika, i ngā rahinga tika, me ngā rautaki tiaki he mea nui kia pai ai te haere o āu mahi, kia whai hua ai hoki. Mā te whakarite i ēnei āhuatanga hei kaupapa matua, ka taea e koe te whakapai ake i te roa o te wā me te pono o āu taputapu.
