Te Hononga i waenganui i te Kōwhiringa o te Pitch o te Mekameka Roera me te Tere
I roto i ngā pūnaha tuku ahumahi, ko te teitei me te tere o te mekameka roera ngā taurangi matua e whakatau ana i te pai o te tuku, te roa o te ora o ngā taputapu, me te pumau o te mahi. He maha ngā miihini me ngā kaimahi hoko, e aro nui ana ki te kaha kawe kawenga i te wā e whiriwhiri ana, ā, ka warewarehia te whakataurite i ēnei āhuatanga e rua. Ko te mutunga iho, ka arahi tēnei ki te pakaru me te pakaru o te mekameka, tae atu ki te wā kore mahi o te raina whakaputa katoa. Ka wetewetehia e tēnei tuhinga ngā mātāpono matua me te whanaungatanga ā-roto i waenga i te teitei me te tere, ka whakaratohia he tikanga whiriwhiri mahi hei āwhina i a koe ki te whiriwhiri i te mekameka roera tino pai mō ngā āhuatanga mahi rerekē.
I. Te Mārama ki ngā Ariā Matua e Rua: Te Whakamāramatanga me te Hiranga Ahumahi o te Pitch me te Tere
I mua i te tātari i te whanaungatanga i waenga i ēnei mea e rua, he mea nui kia whakamāramahia ngā whakamāramatanga taketake—he mea nui tēnei hei karo i ngā hapa kōwhiringa. Ahakoa te whakamahi i ngā mekameka roera ANSI (American Standard), ISO (International Standard), GB (National Standard) rānei, ka noho tonu te pānga matua o te piki me te tere.
1. Te Pito o te Mekameka Roera: Te Whakatau i te "Rahi Utaina" me te "Maeneene o te Oma"
Ko te piko te ine matua o te mekameka roera, e pā ana ki te tawhiti i waenga i ngā pokapū o ngā roera e rua e tata ana (e tohuhia ana e te tohu "p" ā, i te nuinga o te wā ka inehia i roto i te mm, i te inihi rānei). Ka whakatau tika i ngā āhuatanga e rua o te mekameka matua:
Te Kaha Utaina: Ko te teitei o te papa ka hua ake he nui ake ngā wāhanga mekameka pēnei i ngā pereti me ngā pine, ā, he nui ake te kawenga (pūmau me te hihiri) ka taea te kawe, kia pai ai mō ngā mahi taumaha (pēnei i ngā mīhini keri me ngā taputapu kawe taumaha).
Te Maeneene o te Oma: Ka whakaitihia e te iti o te pikinga te "auau pānga" ina hono te mekameka ki te porotiti, ka iti ake te wiri me te haruru i te wā e tukuna ana. Nā tēnei ka pai ake mō ngā tono e hiahia ana kia tino pumau (pērā i ngā taputapu mīhini tino tika me ngā taputapu tākai kai).
2. Tere Hurihanga: Ka whakatau i te "Aumahatanga Hihiri" me te "Auahatanga Pakaru"
Ko te tere hurihuri i konei e pā ana ki te tere o te porotiti taraiwa e hono ana te mekameka (e tohuhia ana e te tohu "n" ā, e inehia ana i roto i te r/min), ehara i te tere o te pito taraiwa. Ko tōna pānga ki te mekameka e whakaatuhia ana i roto i ngā āhuatanga e rua:
Te ahotea hihiri: Ko te tere ake, ko te kaha o te kaha whakatere e puta mai ana i te mekameka i te wā e whakahaerehia ana. Ka nui ake hoki te "kawenga pānga" ina honoa te mekameka ki ngā niho porotiti (he rite ki te pānga o te motuka e rere ana i runga i te puke tere i te tere tiketike).
Te tere o te kakahu: Ka nui ake te tere, ka nui ake te hononga o te mekameka ki te pīkau, ā, ka piki ake te hurihanga o ngā roera me ngā pine. Ka piki ake te nui o te kakahu i taua wā anō, ka whakapoto tika i te roa o te mahi a te mekameka.
II. Arorau Matua: Te Mātāpono "Whakataurite Whakamuri" o te Pitch me te Tere
Kua whakamanahia e ngā mahi ahumahi whānui he mārama te hononga "whakataurite whakamuri" o te teitei me te tere o te mekameka roera—arā, ki te teitei ake te tere, ka iti ake te teitei, engari ki te iti ake te tere, ka nui ake te teitei. Ko te kaupapa matua o tēnei mātāpono ko te whakataurite i ngā "whakaritenga kawenga" me te "mōrearea ahotea hihiri." Ka taea tēnei te wehewehe kia toru ngā taha:
1. Te whakahaere tere-teitei (te tikanga n > 1500 r/min): He mea nui te iti o te oro.
Ina neke atu te tere o te porotiti puku i te 1500 rpm (pērā i ngā pā me ngā puku motuka iti), ka tino piki ake te ahotea hihiri me te kaha porowhita i runga i te mekameka. Mā te whakamahi i tētahi mekameka piko nui i tēnei āhuatanga ka arahi pea ki ngā raruraru nui e rua:
Te taumahatanga o te kawenga pānga: He nui ake ngā hononga o ngā mekameka piko nui, ā, ka nui ake te horahanga pā me te kaha pānga ki ngā niho pītau i te wā e hono ana. Ka taea e tēnei te "peke hononga" te "pakaru niho pītau" rānei i ngā tere tiketike.
Te ngoikore i puta mai i te kaha whakateretere: He nui ake te taumaha mate o ngā mekameka piko nui, ā, mā te kaha whakateretere e puta mai ana i ngā tere teitei ka taea e te mekameka te wetewete i ngā niho o te porokete, ka puta ai te "taka o te mekameka" te "paheke o te taraiwa" rānei. I ngā wā tino kino, ka taea e tēnei te arahi ki ngā tukinga taputapu. Nō reira, mō ngā tono tere teitei, ko ngā mekameka he piko 12.7mm (1/2 inihi) iti iho rānei te nuinga o te wā ka tīpakohia, pērā i te raupapa ANSI #40 me te #50, te raupapa ISO 08B me te 10B rānei.
2. Ngā tono tere-waenga (te tikanga 500 r/min < n ≤ 1500 r/min): Kōwhiria he reo reo-waenga.
Ko ngā whakamahinga tere-waenga te mea e tino kitea ana i roto i ngā whakamahinga ahumahi (pēnei i ngā kaikawe, ngā miro taputapu mīhini, me ngā mīhini ahuwhenua). He mea nui kia taurite te whakaritenga kawenga me ngā whakaritenga maeneene.
Mō ngā kawenga ngāwari (pērā i ngā kaikawe māmā me te mana whakatauranga o te 10kW, iti iho rānei), e taunakihia ana ngā mekameka he piko mai i te 12.7mm ki te 19.05mm (1/2 inihi ki te 3/4 inihi), pērā i te raupapa ANSI #60 me te #80. Mō ngā kawenga teitei ake (pērā i ngā mīhini mīhini rahi-waenga me te mana whakatauranga o te 10kW-20kW), ka taea te whiriwhiri i tētahi mekameka he piko mai i te 19.05mm-25.4mm (3/4-inihi ki te 1-inihi), pērā i te raupapa ANSI #100 me te #120. Heoi, me whakamana anō te whānui o te niho o te porotiti hei ārai i te kore pumau o te whatunga.
3. Te whakahaere tere-iti (te tikanga n ≤ 500 r/min): Ka taea te whiriwhiri i tētahi mekameka pitch nui.
I ngā āhuatanga tere-iti (pērā i ngā mīhini kuru keri me ngā hiki taumaha), he iti noa te ahotea hihiri me te kaha whakatere o te mekameka. Ko te kaha kawe kawenga te mea matua e hiahiatia ana, ā, ka taea te whakamahi katoa i ngā painga o te mekameka piko nui:
He nui ake te kaha o ngā wāhanga o ngā mekameka piko nui, ā, ka taea te tu atu i ngā kawenga pānga o ngā rau kN, ka ārai i te whati o te pereti mekameka me te piko o te pine i raro i ngā kawenga taumaha.
He iti te tere o te pakaru i ngā tere iti, e āhei ai ngā mekameka nui-piko ki te pupuri i te roanga o te ora e rite ana ki te roanga o te ora o ngā taputapu katoa, ā, kāore e hiahiatia he whakakapinga auau (e 2-3 tau te nuinga). Ko ngā mekameka he ≥ 25.4mm (1 inihi) te piko, pērā i te raupapa ANSI #140 me te #160, ngā mekameka taumaha-piko kua whakaritea, e whakamahia whānuitia ana i tēnei horopaki.
III. Aratohu Whaihua: Te Whakataurite Tika i te Pito me te Tere i roto i ngā Hipanga e 4
Kia mārama ki te ariā, kua tae ki te wā ki te whakatinana mā roto i ngā tikanga paerewa. Mā ēnei mahi e whā e whai ake nei koe e āwhina ki te whiriwhiri wawe i tētahi mekameka tika, me te karo i ngā hapa i puta mai i te whakawhirinaki ki te wheako:
Hipanga 1: Tāutuhia ngā Tawhā Matua – Kohia ngā Raraunga Matua e 3 i te Tuatahi
I mua i te whiriwhiri i tētahi mekameka, me whiwhi koe i ēnei tawhā matua e toru o te taputapu; kāore e taea te wareware i tētahi o aua tawhā:
Te tere o te pīrere taraiwa (n): Tikina tēnei tika mai i te motuka, i te pukapuka ā-ringa rānei o te pito taraiwa. Mena ko te tere pito taraiwa anake e wātea ana, tatauhia whakamuri mā te whakamahi i te tātai "Te ōwehenga tuku = te maha o ngā niho i runga i te pīrere taraiwa / te maha o ngā niho i runga i te pīrere taraiwa."
Mana whakawhiti whakatauranga (P): Koinei te mana (i roto i te kW) e hiahiatia ana kia whakawhitia e te taputapu i te wā e mahi noa ana. Kei roto i tēnei ko ngā kawenga tihi (pērā i ngā kawenga ru i te wā e tīmata ana, e tatauhia ana i te nuinga o te wā ko te 1.2-1.5 ngā wā o te mana whakatauranga).
Taiao mahi: Tirohia mēnā he puehu, he hinu, he pāmahana teitei (>80°C), he hau waikura rānei. Mō ngā taiao kino, whiriwhiria ngā mekameka he awaawa whakahinuhinu me ngā paninga ārai-waikura. Me whakanui ake te teitei o te paparanga mā te 10%-20% kia kore ai e pakaru.
Hipanga 2: Te Kōwhiringa o te Awhe Pitch Tuatahi i runga i te Tere
Tirohia te ripanga i raro nei hei whakatau i te whānuitanga o te piko tuatahi i runga i te tere o te pīkau taraiwa (mā te whakamahi i te mekameka paerewa ANSI hei tauira; ka taea te huri i ētahi atu paerewa kia rite ki tēnā):
Tere o te Pīrere Taraiwa (r/min) Te Awhe o te Pitch e Manakohia ana (mm) Ngā Raupapa Mekameka ANSI e rite ana Ngā Whakamahinga Noa
>1500 6.35-12.7 #25, #35, #40 Ngā Pā, Ngā Mōta Iti
500-1500 12.7-25.4 #50, #60, #80, #100 Ngā Kawe, Ngā Utauta Mīhini
<500 25.4-50.8 #120, #140, #160 Kaitukituki, Ararewa
Hipanga 3: Manatokohia te Tūtaki o te Papa ki te Kaha Utaina mā te whakamahi i te Mana
Whai muri i te kōwhiringa tuatahi o te piko, me whakamana kia taea e te mekameka te tu atu i te mana kua whakatauria mā te whakamahi i te "Tātai Tatau Mana" hei karo i te rahunga taumaha. Hei tauira, ko te tātai kua whakangawaritia koia tēnei:
Te tuku mana e whakaaetia ana e te mekameka (P₀) = K₁ × K₂ × Pₙ
Ko te K₁ te tauwehenga whakatikatika tere (ko te K₁ ka iti ake i ngā tere teitei ake, ka kitea i roto i te rārangi mekameka); ko te K₂ te tauwehenga whakatikatika āhua mahi (0.7-0.9 mō ngā taiao kino, 1.0-1.2 mō ngā taiao ma); ā, ko te Pₙ te mana whakatauranga o te mekameka (ka kitea mā te pitch i roto i te rārangi a te kaihanga).
Tikanga manatoko: Me tutuki i a P₀ te ≥ 1.2 × P (ko te 1.2 te tauwehenga haumaru, ka taea te whakanui ake ki te 1.5 mō ngā āhuatanga mahi taumaha).
Hipanga 4: Whakatikatikahia te mahere whakamutunga i runga i te wāhi tāutanga.
Mena he iti te wāhi tāutanga mō te papa i whiriwhiria tuatahitia (hei tauira, he kuiti rawa te wāhi o roto o te taputapu hei whakauru i tētahi mekameka papa nui), e rua ngā whakarerekētanga ka taea te mahi:
Whakaitihia te teitei + whakanuia te maha o ngā rarangi mekameka: Hei tauira, mēnā i whiriwhiria e koe tētahi rarangi o te teitei 25.4mm (#100), ka taea e koe te huri ki ngā rarangi e rua o te teitei 19.05mm (#80-2), he rite te kaha kawenga engari he iti ake te rahi.
Te whakanui ake i te maha o ngā niho o te pīkau: Ahakoa te pupuri tonu i te teitei kotahi, mā te whakanui ake i te maha o ngā niho o te pīkau taraiwa (kia 17 ngā niho pea te iti rawa) ka taea te whakaiti i te ru o te hononga mekameka, ā, ka whakapai ake hoki i te ngāwari o te urutau ki te tere teitei.
IV. Ngā Hapa Noa hei Ārai: Ārai i ēnei Hapa e 3
Ahakoa kua mōhio kē rātou ki te tukanga whiriwhiri, he tokomaha tonu te hunga e hinga ana nā te kore e aro ki ngā taipitopito. Anei ētahi o ngā whakaaro hē e toru me ō rātou otinga:
Whakaaro Hē 1: Te arotahi anake ki te kaha kawe kawenga me te kore e aro ki te taurite tere
He Whakaaro Hē: Te whakapono "ko te teitei o te oro he nui ake te kaha ki te kawe kawenga," ka tīpakohia he mekameka oro nui ake mō te mahi tere-teitei (hei tauira, he mekameka #120 mō te motuka 1500 rpm). Ngā Huanga: Neke atu i te 90dB ngā taumata haruru mekameka, ā, ka puta ngā pakaru pereti mekameka i roto i ngā marama e rua ki te toru. Otinga: Kōwhiria ngā oro i runga i te "matua tere". Mena kāore i te rawaka te kaha kawenga, me whakanui ake te whakanui i te maha o ngā rarangi kaua te whakanui i te oro.
Whakaaro Hē 2: Te whakapoauau i te "tere o te pūrakau taraiwa" me te "tere o te pūrakau taraiwa"
Whakaaro hē: Mā te whakamahi i te tere o te pūrei taraiwa hei tauwehenga whiriwhiri (hei tauira, mēnā he 500 rpm te tere o te pūrei taraiwa, ā, ko te tere tuturu o te pūrei taraiwa he 1500 rpm, ka tīpakohia he pikinga nui ake i runga i te 500 rpm). Ngā hua: He nui rawa te ahotea hihiri i roto i te mekameka, ka hua ake he "pakaru nui o te pine" (ka neke atu i te 0.5mm te kakahu i roto i te kotahi marama). Otinga: Me whakamahi te "tere o te pūrei taraiwa" hei paerewa. Ki te kore e tino mārama, tatauhia mā te whakamahi i te tere motuka me te ōwehenga whakaiti (tere o te pūrei taraiwa = tere motuka / ōwehenga whakaiti).
Whakaaro Hē 3: Te Whakahāwea i te Pānga o te Whakahinuhinu ki te Taurite Tere-Pōro
He hapa: te whakaaro "he nui te whiriwhiri i te pikinga tika," te karo i te whakahinuhinu, te whakamahi rānei i te whakahinuhinu ngoikore i raro i ngā āhuatanga tere teitei. Ngā hua: Ahakoa he pikinga iti, ka taea te whakapoto i te roa o te mekameka neke atu i te 50%, ā, ka taea hoki te pā mai o te waku maroke. Otinga: Mō ngā āhuatanga tere teitei (n > 1000 rpm), me whakamahi te whakahinuhinu maturuturu, te whakahinuhinu kaukau hinu rānei. Me ōrite te matotoru o te whakahinuhinu ki te tere (ko te teitei ake o te tere, ko te iti ake o te matotoru).
V. Akoranga Take Ahumahi: Te Arotautanga mai i te Rahunga ki te Pūmautanga
I pakaru te mekameka i tētahi raina kawe i tētahi wheketere wāhanga motuka i te marama. Mā te arotau i te taurite o te tere-piko, i whakaroahia e mātou te roa o te ora o te mekameka ki te rua tau. Ko ngā taipitopito e whai ake nei:
Mahere Taketake: Te tere o te pūrakau taraiwa 1200 rpm, mekameka rarangi kotahi me te nekehanga 25.4mm (#100), te tuku mana 8kW, kāore he hinu whakahinuhinu ākiaki.
Te take o te rahunga: Kei te rohe o runga o te tere waenga te 1200 rpm, ā, ka nui rawa te ahotea hihiri o te mekameka piko 25.4mm i tēnei tere. Hei tāpiri, ko te kore o te hinu whakahinuhinu ka tere ake te pakaru.
Mahere arotau: Whakaitihia te piko ki te 19.05mm (#80), whakawhiti ki te mekameka rarangi-rua (#80-2), ka tāpirihia he pūnaha whakahinuhinu maturuturu.
Ngā hua arotau: I whakaitihia te haruru o te mekameka mai i te 85dB ki te 72dB, i whakaitihia te pakaru o te mekameka ia marama mai i te 0.3mm ki te 0.05mm, ā, i whakaroahia te roa o te ora o te mekameka mai i te 1 marama ki te 24 marama, ā, i penapenahia e ia neke atu i te 30,000 yuan i roto i ngā utu whakakapinga ia tau.
Whakatau: Ko te uho o te kōwhiringa ko te taurite.
Ehara i te mea ngāwari te whiriwhiri i te "rahi, iti rānei" o te mekameka roera. Engari, ko te mea nui ko te kimi i te taurite pai i waenga i te kaha kawenga, te tere whakahaere, te wāhi tāutanga, me te utu. Mā te mōhio ki te kaupapa o te "whakataurite whakamuri," te whakakotahi i tēnei me te tukanga whiriwhiri paerewa e whā-taahiraa me te karo i ngā hapa noa, ka taea e koe te whakarite i tētahi pūnaha tuku pumau me te roa.
