I roto i ngā whakamātautau o ia rā, hei tāpiri atu ki ngā tawhā tika o ngā taputapu tonu, kua whakaarohia e koe te pānga o te ine rahi tauira ki ngā hua whakamātautau? Ka whakakotahihia e tēnei tuhinga ngā paerewa me ngā take motuhake hei hoatu i ētahi whakaaro mō te ine rahi o ētahi rauemi noa.
1. E hia te pānga o te hapa i te ine i te rahi o te tauira ki ngā hua o te whakamātautau?
Tuatahi, e hia te rahi o te hapa whanaunga i puta mai i te hapa. Hei tauira, mō te hapa 0.1mm kotahi, mō te rahi 10mm, ko te hapa he 1%, ā, mō te rahi 1mm, ko te hapa he 10%;
Tuarua, he aha te nui o te awe o te rahi ki te hua. Mō te tātai tatau kaha piko, he pānga tuatahi tō te whānui ki te hua, ko te matotoru ia he pānga tuarua ki te hua. Ina rite te hapa whanaunga, ka nui ake te pānga o te matotoru ki te hua.
Hei tauira, ko te whānui me te matotoru paerewa o te tauira whakamātautau piko he 10mm me te 4mm, ā, ko te modulus piko he 8956MPa. Ina whakaurua te rahi tuturu o te tauira, ko te whānui me te matotoru he 9.90mm me te 3.90mm, ka eke te modulus piko ki te 9741MPa, he pikinga tata ki te 9%.
2. He aha te mahi a ngā taputapu ine rahi tauira noa?
Ko ngā taputapu ine ine e whakamahia whānuitia ana i ēnei rā ko ngā maikiromita, ngā caliper, ngā ine matotoru, me ētahi atu.
Ko te whānuitanga o ngā maikoromita noa kāore e neke ake i te 30mm, ko te taumira he 1μm, ā, ko te hapa tohu mōrahi he tata ki te ±(2~4)μm. Ka taea e te taumira o ngā maikoromita tino tika te eke ki te 0.1μm, ā, ko te hapa tohu mōrahi he ±0.5μm.
Kei roto i te maikoromita he uara kaha ine pumau, ā, ka taea e ia inenga te whakaputa i te hua ine i raro i te āhua o te kaha pa pumau, he mea e tika ana mō te ine i ngā āhuatanga o ngā rauemi mārō.
Ko te whānuitanga ine o te caliper tikanga kāore i te neke atu i te 300mm, ko te taumira he 0.01mm, ā, ko te hapa tohu mōrahi he ±0.02~0.05mm. Ka taea e ētahi caliper nui te eke ki te whānuitanga ine o te 1000mm, engari ka piki ake anō hoki te hapa.
Ko te kaha o te caliper e whakawhirinaki ana ki te mahi a te kaiwhakahaere. Ko ngā hua ine o te tangata kotahi he pumau tonu, ā, ka rerekē ngā hua ine o ngā tāngata rerekē. He pai mō te ine i ngā āhuatanga o ngā rauemi pakeke me te ine i ngā āhuatanga o ētahi rauemi ngohengohe nui.
He rite tonu te haere, te tika, me te taumira o te ine matotoru ki ērā o te maikiromita. Ka whakaratohia hoki e ēnei taputapu he pēhanga pumau, engari ka taea te whakarite i te pēhanga mā te whakarerekē i te kawenga i runga. I te nuinga o te wā, he pai ēnei taputapu mō te ine i ngā rauemi ngohengohe.
3. Me pēhea te whiriwhiri i te taputapu ine rahi tauira e tika ana?
Ko te mea nui ki te whiriwhiri i ngā taputapu ine ā-ahu, kia tino kitea ngā hua whakamātautau e tika ana, ā, ka taea te whakahoki. Ko te mea tuatahi me whakaaro tātou ko ngā tawhā taketake: te whānuitanga me te tika. Hei tāpiri, ko ngā taputapu ine ā-ahu e whakamahia whānuitia ana pērā i ngā maikoromita me ngā calipers he taputapu ine whakapā. Mō ētahi āhua motuhake, mō ngā tauira ngohengohe rānei, me whakaaro hoki tātou ki te awe o te āhua o te probe me te kaha whakapā. Inaa, he maha ngā paerewa kua whakatakoto i ngā whakaritenga e rite ana mō ngā taputapu ine ā-ahu: E whakatau ana te ISO 16012:2015 mō ngā splines i hangaia ki te werohanga, ka taea te whakamahi i ngā maikoromita, ine matotoru maikoromita rānei hei ine i te whānui me te matotoru o ngā tauira i hangaia ki te werohanga; mō ngā tauira mīhini, ka taea hoki te whakamahi i ngā calipers me ngā taputapu ine kore-pā. Mō ngā hua ine ā-ahu <10mm, me noho te tika ki roto i te ±0.02mm, ā, mō ngā hua ine ā-ahu ≥10mm, ko te whakaritenga tika ko ±0.1mm. E whakatau ana te GB/T 6342 i te tikanga ine ā-ahu mō ngā kirihou pahuka me te rapa. Mō ētahi tauira, e whakaaetia ana ngā maikoromita me ngā caliper, engari he mea tino whakarite te whakamahinga o ngā maikoromita me ngā caliper kia kore ai te tauira e pāngia e ngā kaha nui, ka hua ake he hua ine hē. Hei tāpiri, mō ngā tauira he iti iho i te 10mm te matotoru, e taunaki ana hoki te paerewa kia whakamahia he maikoromita, engari he tino whakaritenga mō te ahotea whakapā, arā, 100±10Pa.
E whakamārama ana te GB/T 2941 i te tikanga ine ā-ahu mō ngā tauira rapa. He mea tika kia mōhiotia, mō ngā tauira he iti iho i te 30mm te matotoru, e whakamārama ana te paerewa ko te āhua o te ine he waewae pēhanga porowhita papatahi me te diameter o te 2mm~10mm. Mō ngā tauira he pakeke ≥35 IRHD, ko te kawenga e pā ana ko te 22±5kPa, ā, mō ngā tauira he iti iho i te 35 IRHD te pakeke, ko te kawenga e pā ana ko te 10±2kPa.
4. He aha ngā taputapu ine ka taea te tūtohu mō ētahi rauemi noa?
A. Mō ngā tauira kume kirihou, e taunakihia ana kia whakamahia he maikiromita hei ine i te whānui me te matotoru;
B. Mō ngā tauira pānga kua whakakōkīhia, ka taea te whakamahi i te maikiromita, i te ine matotoru rānei me te taumira o te 1μm hei ine, engari kaua te pūtoro o te pewa i raro i te ine e neke ake i te 0.10mm;
C. Mō ngā tauira kiriata, e taunakihia ana he ine matotoru he pai ake te taumira i te 1μm hei ine i te matotoru;
D. Mō ngā tauira kume rapa, e taunakihia ana he ine matotoru hei ine i te matotoru, engari me aro nui ki te rohe me te kawenga o te tirotiro;
E. Mō ngā rauemi pahuka angiangi, e taunakihia ana he ine matotoru motuhake hei ine i te matotoru.
5. Haunga te whiriwhiri taputapu, he aha atu anō ngā mea hei whakaaroaro māu ina ine ana i ngā inenga?
Me whakaaro te tūnga ine o ētahi tauira hei tohu i te rahi tuturu o te tauira.
Hei tauira, mō ngā whīra piko i whakarewaina ki te werohanga, kāore e neke ake i te 1° te koki tauira i te taha o te whīra, nō reira ka taea e te hapa i waenga i te whānui mōrahi me te whānui mōkito te eke ki te 0.14mm.
Hei tāpiritanga, ka pāngia ngā tauira i werohia kia heke te pāmahana, ā, ka nui te rerekētanga i waenga i te ine i waenganui me te taha o te tauira, nō reira ka tohua hoki e ngā paerewa e tika ana te tūranga ine. Hei tauira, e hiahiatia ana e te ISO 178 kia ±0.5mm te tūranga ine o te whānui o te tauira mai i te pokapū matotoru, ā, kia ±3.25mm te tūranga ine matotoru mai i te pokapū whānui.
Haunga te whakarite kia tika te ine i ngā inenga, me āta tupato hoki kia kore ai e puta he hapa i puta mai i ngā hapa whakauru a te tangata.
