Ngā whakatūpato mō te tuku mekameka roera

I roto i te mara o te tuku miihini,mekameka roeraHe whānuitia te whakamahinga o te tuku hiko nā te mea he tino whai hua, he pono hoki. Heoi, kia pai ai te mahi, kia roa ai hoki te ora o te pūnaha tuku hiko mekameka roera, me mārama ēnei kōrero matua.

1. Ngā whakatūpato tāutanga
(I) Te ōwehenga tuku me te koki takai
Ko te ōwehenga tuku o te tuku mekameka roera he 7:1 te tikanga, ā, ka taea te eke ki te 10:1 i te tere tino iti. Me pupuri te koki takai o te sprocket iti me te mekameka ki runga ake i te 120°, ā, me eke te tuku whakatārewatanga ki runga ake i te 90°. Mā te ōwehenga tuku me te koki takai tika ka taea te whakarite i te pai o te tuku me te roa o te ora ratonga o te mekameka.
(II) Te tawhiti i waenga i ngā tuaka
Ko te uara pai mō te tawhiti pokapū i waenga i ngā porotiti e rua he 30-50 ngā wā o te nekehanga o te mekameka roera. Mēnā he nui te rerekētanga o te kawenga i te wā e kawe ana, ka taea te whakatakoto i te tawhiti pokapū ki raro iho i te 20 ngā wā. Mā te tawhiti tika i waenga i ngā toki ka āwhina ki te whakaiti i te pakaru me te wiri o te mekameka.
(III) Te nui o te taha wetekina
Kāore e hiahiatia he whakatōtōtanga tuatahi mō te tuku mekameka roera, engari me whakatakoto kia iti te wetewete. Me whakarite te nui o te ngenge kia rite ki ngā āhuatanga mahi motuhake. I te nuinga o te wā, ko te nui o te ngenge he tata ki te 4% o te whānui. Mō te tuku poutū, te tawhiti pokapū nui, te kawenga taumaha, te mahi whakamuri rānei, me 2% o te whānui te nui o te ngenge.
(IV) Te whakarara me te whakapae o te rakau
He mea nui te tika o te tāutanga o te porotiti ki te roa o te mahi me te mahi noa o te mekameka roera. Whakamahia he taumata wai hei whakatika i te whakapae o ngā toki e rua kia mau tonu ai te awhe o te ±1/300; whakamahia he caliper hei whakatika i te whakarara o ngā toki e rua kia mau tonu ai te awhe o te ±1/300. Mō ngā tawhiti pokapū rerekē, ko ngā whakaritenga tika o te porotiti koia ēnei:
Te tawhiti o te pokapū ki te 1m: ±1mm
Te tawhiti pokapū 1~10m: ±1mm
Te tawhiti pokapū i runga ake i te 10m: ±10mm
(V) Whirihoranga tāutanga
Ko te tata atu o te rārangi hononga pokapū o ngā porotiti e rua ki te whakapae, ko te pai ake o te pānga tuku o te mekameka roera. Mō te tuku poutū, te tuku āhua-poutū rānei, me whakamahi he wira mangere, he whakapūmau rānei kia taea ai te tango maeneene i te porotiti ina paku toronga te mekameka. Me mōhio hoki ki ēnei āhuatanga i te wā tāutanga:
Ina poto te tawhiti o waenganui, ka taea te whakaroa i te tawhiti o waenganui mā te neke i te tautoko o te kakau kia paku kumekume ai te mekameka.
Ina roa te tawhiti i waenganui, ka taea te tāpiri i tētahi wira mangere ki te taha o roto o te taha wetekina hei tautoko i te mekameka roera.
Mō ngā mekameka e oma ana i te tere tiketike, me ngā kawenga rerekē, mā te whakamahi i ngā aukati arataki mekameka ka taea te whakaiti i te wiri.
Ina poutū te tuku, ka taea te tāuta i te ātete hei whakatika i te ātete mekameka i te wā tika kia tika ai te hononga o te sprocket me te mekameka.

2. Ngā whakatūpato mō te whakahinuhinu
(I) Te hiranga o te whakahinuhinu
He mea nui te whakahinuhinu i roto i te tukunga o te mekameka roera. Mā te whakahinuhinu pai ka taea te whakaiti i te pakaru o te mekameka, te whakaiti i te haruru, me te ārai i te waikura, ā, ka roa ake te ora o te mekameka. Mā te kore e ranea, te kore rānei e tika te whakahinuhinu ka ara ake ngā raruraru pēnei i te pakaru wawe me te whati o te mekameka.
(II) Ngā tikanga whakahinuhinu
I runga i te taiao whakamahi me ngā āhuatanga mahi, ko ngā huarahi matua hei whakahinuhinu i ngā mekameka roera ko:
Te whakakī hinu ā-ringa: he pai mō ngā pūnaha tuku tere-iti, kawenga-māmā. Pania te hinu whakahinuhinu tika i waenganui i te pine me te ringaringa o te mekameka.
Whakahinuhinu kaukau hinu: Ka rumakina te mekameka ki roto i te tāke hinu, ā, ka whakahinuhinuhia te mekameka e te tohanga hinu. He pai mō ngā pūnaha tuku tere-waenga me ngā pūnaha tuku kawenga-waenga.
Whakahinuhinu Pāhū: Ka tāutahia he pereti whakapiri hinu ki roto i te whare, ā, ka tauhiuhia te hinu whakahinuhinu ki runga i te mekameka mā te pereti whakapiri hinu. He pai mō ngā pūnaha tuku tere-nui me te kawenga-waenga.
Whakahinuhinu ākiaki: Ka ākiakihia te hinu whakahinuhinu kia tukuna ki ngā wāhanga rerekē o te mekameka mā te whakamahi i te papu hinu. He pai mō ngā pūnaha tuku tere-nui me ngā pūnaha tuku taumaha.
(III) Te kōwhiringa hinu whakahinuhinu
Me whiriwhiri te hinu whakahinuhinu i runga i te taiao mahi me te pāmahana o te mekameka. I te nuinga o te wā, me taurite te matotoru o te hinu whakahinuhinu, kia pai ai te pānga whakahinuhinu me te kore e aukati i te awa whakahinuhinu nā te matotoru nui rawa. Mō ngā awhe pāmahana rerekē, ko te matotoru hinu whakahinuhinu e taunakitia ana koia tēnei:
-10℃～0℃: SAE10W
0℃～40℃: SAE20
40℃～50℃: SAE30
50℃～60℃: SAE40

Te wiri o te mekameka: Tērā pea nā te koretake o te piri o te mekameka, te koretake o te hinu whakahinuhinu, te koretake rānei o te tāutanga o te porotiti. Ko te otinga he whakarerekē i te piri o te mekameka, tirohia te pūnaha whakahinuhinu me te tūnga tāutanga o te porotiti.
(II) Ngā tikanga rapurongoā
Te whati o te mekameka: Whakakapia te mekameka, tirohia hoki te pūnaha whakahinuhinu.
Te roa o te mekameka: Whakakapia te mekameka.
Te pakaru o te pītau: Whakakapia te pītau ka tirohia te pūnaha whakahinuhinu.
Te rūrū mekameka: Whakatikatikahia te pūmau o te mekameka, tirohia te pūnaha whakahinuhinu me te tūnga tāutanga o te porotiti.

5. Ngā whakatūpato mō te roa o te wā e whakamahia ana
(I) Te whakatau i te roanga o te ratonga
Ko te roa o te mahi a ngā mekameka roera ka aromatawaihia mā te roa o te mekameka. Ina tae te roa o te mekameka ki te 1.5% o tōna roa, me whakakapi te mekameka. Hei tāpiri, me tirotiro tonu te pakaru, te whakahinuhinu me te pakaru o te mekameka me te porotiti kia pai ai te mahi a te pūnaha tuku.
(II) Ngā tikanga hei whakaroa i te roa o te ratonga
Tāutanga tika: Tāutahia kia rite ki ngā whakaritenga tāutanga kia tika ai te hononga o te mekameka me te pīkau.
He pai te whakahinuhinu: Tirohia me te whakakapi i te hinu whakahinuhinu i ia wā, i ia wā, kia tino whakahinuhinuhia ngā wāhanga katoa o te mekameka.
Tirotiro auau: Tirohia te pakaru, te piri me te whakahinuhinu o te mekameka i ia wā, kia kitea ai, kia ea ai hoki ngā raruraru i te wā tika.
Āraia te uta nui rawa: Āraia te whakahaere i te mekameka i raro i te uta nui rawa hei whakaiti i te pakaru me te ngenge o te mekameka.

6. Ngā whakatūpato mō te kōwhiringa
