Rerekētanga mahi motuka 1: tere/taipana/rahi
He momo mōta katoa o te ao. He mōta nui, he mōta iti. He mōta e neke whakamua ana, e anga whakamua ana, kaua e hurihuri. He mōta kāore i te mārama i te tirohanga tuatahi he aha te utu nui. Heoi, he take anō kei te whiriwhiria ai ngā mōta katoa. Nō reira, he aha te momo mōta, te mahi, ngā āhuatanga rānei e hiahiatia ana e tō mōta tino pai?
Ko te kaupapa o tēnei raupapa he whakarato mātauranga mō te whiriwhiri i te mōtini tino pai. Ko te tumanako ka whai hua tēnei ina whiriwhiri koe i tētahi mōtini. Ā, ko te tumanako ka āwhina i te tangata ki te ako i ngā kaupapa matua o ngā mōtini.
Ka wehea ngā rerekētanga mahi hei whakamārama kia rua ngā wāhanga motuhake penei:
Tere/Taipana/Rahi/Utu ← Ngā mea ka matapakihia e tātou i tēnei upoko
Te tere tika/te maeneene/te roa me te tiaki/te whakaputa puehu/te whai hua/te wera
Te whakaputa hiko/te wiri me te haruru/ngā ārai i te hauhautanga/te taiao whakamahi
1. Ngā tumanakohanga mō te motuka: te nekehanga hurihuri
Ko te tikanga, ko te mōta he mōta e whiwhi ana i te pūngao ā-pūkaha mai i te pūngao hiko, ā, i te nuinga o te wā, e pā ana ki te mōta e whiwhi ana i te nekehanga hurihuri. (Tērā anō hoki he mōta raina e whiwhi ana i te nekehanga tika, engari kāore e whakahuatia i tēnei wā.)
Nā, he aha te momo hurihanga e hiahiatia ana e koe? E hiahia ana koe kia huri kaha pērā i te wiri, kia huri ngoikore rānei engari i te tere teitei pērā i te pā hiko? Mā te arotahi ki te rerekētanga o te nekehanga hurihanga e hiahiatia ana, ka nui haere ngā āhuatanga e rua o te tere hurihanga me te taipana.
2. Taipana
Ko te taipana te kaha o te hurihanga. Ko te waeine o te taipana ko N·m, engari mō ngā motuka iti, ko te mN·m te mea e whakamahia whānuitia ana.
He maha ngā huarahi i hangaia ai te mōta hei whakanui ake i te taipana. Ka nui ake ngā hurihanga o te waea hikohiko, ka nui ake te taipana.
Nā te mea he iti noa te rahi o te koiri pumau mō te maha o ngā takai, ka whakamahia he waea enamel he nui ake te diameter o te waea.
Ko tā mātou raupapa mōtini kore paraihe (TEC) me te 16 mm, 20 mm me te 22 mm me te 24 mm, 28 mm, 36 mm, 42 mm, ngā momo e 8 o te rahi o waho 60 mm. Nā te mea ka piki ake te rahi o te koiri me te diameter o te mōtini, ka taea te whiwhi taipana teitei ake.
Ka whakamahia ngā aukume kaha hei whakaputa i ngā taipana nui, me te kore e whakarerekē i te rahi o te motuka. Ko ngā aukume neodymium ngā aukume tuturu tino kaha, ā, whai muri ko ngā aukume samarium-cobalt. Heoi, ahakoa he aukume kaha anake ka whakamahia e koe, ka turuturu te kaha aukume i waho o te motuka, ā, kāore te kaha aukume turuturu e whai wāhi ki te taipana.
Hei whakamahi tika i te kaha o te aukumetanga, ka whakakikoruatia he rauemi angiangi mahi e kiia nei ko te pereti maitai hikohiko hei whakapai ake i te ara iahiko aukume.
Heoi anō, nā te mea he pumau te kaha aukume o ngā aukume samarium cobalt ki ngā huringa pāmahana, ka taea e te whakamahinga o ngā aukume samarium cobalt te taraiwa i te motuka i roto i te taiao e nui ana ngā huringa pāmahana, e teitei ana rānei.
3. Tere (hurihanga)
Ko te maha o ngā hurihanga o te motuka e kiia ana ko te "tere". Koinei te mahi o te maha o ngā hurihanga o te motuka i ia wā. Ahakoa e whakamahia whānuitia ana te "rpm" hei hurihanga ia meneti, ka whakaatuhia hoki ko te "min-1" i roto i te pūnaha waeine SI.
Ki te whakatauritea ki te taipana, ehara i te mea uaua te whakanui ake i te maha o ngā hurihanga. Whakaitihia noa te maha o ngā hurihanga i roto i te koiri hei whakanui ake i te maha o ngā hurihanga. Heoi, i te mea ka heke te taipana i te pikinga o te maha o ngā hurihanga, he mea nui kia tutuki ngā whakaritenga taipana me te hurihanga.
Hei tāpiritanga, ki te whakamahia i te tere nui, he pai ake te whakamahi i ngā peera pōro kaua ki ngā peera noa. Ka nui ake te tere, ka nui ake te ngaronga ātete ki te waku, ka poto ake te ora o te motuka.
I runga i te tika o te toki, ka nui ake te haruru me ngā raruraru e pā ana ki te wiri, ka nui ake te tere. Nā te mea kāore he paraihe, he kaitahuri rānei o te mōtini kore paraihe, he iti ake te haruru me te wiri e puta mai ana i te mōtini paraihe (e pā ana te paraihe ki te kaitahuri hurihuri).
Hipanga 3: Rahi
Mō te mōtini tino pai, ko te rahi o te mōtini tētahi o ngā mea nui o te mahi. Ahakoa he rawaka te tere (ngā hurihanga) me te taipana, kāore he painga mena kāore e taea te tāuta ki te hua whakamutunga.
Ki te hiahia noa koe ki te whakanui ake i te tere, ka taea e koe te whakaiti i te maha o ngā hurihanga o te waea, ahakoa he iti te maha o ngā hurihanga, engari ki te kore he taipana iti rawa, e kore e huri. Nō reira, me kimi huarahi hei whakanui ake i te taipana.
Haunga te whakamahi i ngā aukume kaha o runga ake nei, he mea nui anō hoki kia whakanuia te tauwehenga huringa mahi o te takai. Kua kōrero tātou mō te whakaiti i te maha o ngā takai waea kia mau tonu ai te maha o ngā hurihanga, engari ehara tēnei i te kī he koretake te takai o te waea.
Mā te whakamahi i ngā waea matotoru, kaua ki te whakaiti i te maha o ngā takai, ka taea te rere o te iahiko nui, ā, ka taea te whiwhi i te taipana teitei ahakoa te tere ōrite. Ko te tauwehenga ā-wāhi he tohu mō te piri o te takai o te waea. Ahakoa he whakanui ake i te maha o ngā takai angiangi, he whakaiti rānei i te maha o ngā takai matotoru, he mea nui tēnei hei whiwhi taipana.
I te nuinga o te wā, e rua ngā āhuatanga e whakawhirinaki ana ki te putanga o te mōta: te rino (aukume) me te parahi (takahuri).
