Mena kei te rapu koe i te mekameka roera mō āu mīhini ahumahi, tera pea kua tūtaki koe ki ngā kupu "mekameka roera 40" me te "mekameka roera 41." E whakamahia whānuitia ana ēnei momo mekameka roera i roto i ngā mahi maha, engari he aha te mea e wehewehe ana i a rāua? I roto i tēnei tuhinga, ka tūhuratia e mātou ngā rerekētanga i waenga i te mekameka roera 40 me te 41 hei āwhina i a koe ki te whakatau whai whakaaro mō ō hiahia.
Tuatahi, he mea nui kia mārama ko ngā mekameka roera 40 me te 41 he wāhanga o te raupapa mekameka roera paerewa ANSI (American National Standards Institute). Ko te tikanga he mea hanga ēnei ki ngā rahi me ngā paerewa kounga motuhake, ka taea te whakawhiti me ētahi atu mekameka roera paerewa ANSI. Heoi, ahakoa ō rātou āhua ōrite, he rerekētanga matua kei reira e wehewehe ana i te mekameka roera 40 me te 41.
Ko tētahi o ngā rerekētanga matua i waenga i te mekameka roera 40 me te 41 kei roto i tōna teitei. Ko te teitei o te mekameka roera e pā ana ki te tawhiti i waenga i ngā pokapū o ngā pine tata, ā, he mea nui ki te whakatau i te kaha me te kaha o te mekameka ki te kawe kawenga. Mō te mekameka roera 40, ko te teitei o te teitei he 0.5 inihi, ko te teitei o te mekameka roera 41 he iti ake i te 0.3125 inihi. Ko te tikanga he pai ake te mekameka roera 40 mō ngā mahi e hiahia ana ki te kaha me te roa, ko te mekameka roera 41 he pai ake pea mō ngā mahi mama ake.
Haunga te piko, ko tētahi atu mea nui hei whakaaroaro mā te whakataurite i te mekameka roera 40 me te 41 ko ō rāua kaha kume. Ko te kaha kume e pā ana ki te nui rawa o te ahotea kume ka taea e te rauemi te tu atu me te kore e whati, ā, he mea nui tēnei hei whakaaroaro mā te whakatau i te pai o te mekameka roera mō tētahi tono. I te nuinga o te wā, he nui ake te kaha kume o te mekameka roera 40 i te mekameka roera 41, ā, koinei te whiringa pai mō ngā tono taumaha ka pāngia te mekameka e ngā kawenga me ngā kaha nui.
Hei tāpiritanga, he paku rerekē ngā āhuatanga o ngā wāhanga takitahi o te mekameka roera 40 me te 41. Hei tauira, ko te whānui o ngā roera i runga i te mekameka roera 40 he nui ake i te mekameka roera 41, e āhei ai te pai ake o te whakapā atu me te hononga ki ngā porotiti. Ka pā pea tēnei rerekētanga o te rahi o te roera ki te mahi whānui me te whai huatanga o te mekameka i roto i ngā momo mahi.
Ko tētahi atu mea nui hei whakaaroaro māu i te wā e whiriwhiri ana i waenga i te mekameka roera 40 me te 41 ko te wātea o ngā sprocket me ētahi atu taputapu. Nā te mea he nui ake te whakamahinga o te mekameka roera 40 i ngā wāhi ahumahi, he māmā ake pea te kimi i te whānuitanga o ngā sprocket me ngā taputapu hototahi mō te mekameka roera 40 ki te whakaritea ki te mekameka roera 41. He mea nui pea tēnei i roto i ētahi tono e hiahiatia ana he rahi, he whirihoranga rānei o ngā sprocket.
Hei whakamutunga, ko te whiriwhiri i waenga i te mekameka roera 40 me te 41 ka whakawhirinaki ki ngā whakaritenga motuhake o tō tono. Mena kei te hiahia koe ki tētahi mekameka roera ka taea te whakahaere i ngā kawenga taumaha, ā, ka whakarato mahi pono i roto i ngā āhuatanga uaua, ko te mekameka roera 40 te kōwhiringa pai ake. I tētahi atu taha, ki te mea he mama ake ngā kawenga o tō tono, ā, me hiahia he hoahoa mekameka kiato ake, ko te mekameka roera 41 te mea tika ake.
Hei whakamutunga, ahakoa he wāhanga o te raupapa paerewa ANSI te mekameka roera 40 me te 41, he rerekē rāua i runga i te piko, te kaha kume, ngā rahi o ngā wāhanga, me te pai o te tono. He mea nui te mārama ki ēnei rerekētanga i roto i te whiriwhiri i te mekameka roera tika mō ō mīhini me ō taputapu. Mā te whai whakaaro ki ngā whakaritenga motuhake o tō tono me te whakaaro ki ngā āhuatanga ahurei o ia momo mekameka roera, ka taea e koe te whakatau whai whakaaro hei whakarite i te mahi tino pai me te pono. Ahakoa he mekameka roera 40, 41 rānei tāu e whiriwhiri ai, ka taea e koe te whakawhirinaki kua hangaia ngā kōwhiringa e rua kia tutuki ai ngā paerewa kounga me te mahi tino teitei mō ō hiahia ahumahi.
