He hua matua ngā mekameka roera i roto i ngā momo ahumahi pēnei i te mīhini, te motuka me te ahuwhenua. He mea hanga ēnei mekameka maha-whakamahinga hei tuku i te mana miihini, hei wāhanga nui o ngā mahi maha. Heoi, he mahi uaua te whiriwhiri i te rahi tika o te mekameka roera, inā koa mō te hunga hou ki te mara. Ko te whāinga o tēnei aratohu whānui he whakamārama i te tukanga me te whakangāwari ake i te whakatau a ngā kaiwhakamahi i te rahi pai o te mekameka roera mō ā rātou hiahia.
Akohia ngā rahi o ngā mekameka roera:
I mua i te ruku hohonu ki ngā āhuatanga uaua o te whiriwhiri i te rahi tika o te mekameka roera, me mōhio tātou ki te pūnaha e whakamahia ana hei tohu i tōna rahi. Ko te tohu o te mekameka roera ko tōna teitei, e tohu ana i te tawhiti i waenga i ngā pokapū o ngā pine roera e rua e tata ana. Ko te teitei e whakaatuhia ana i roto i ngā inihi, i ngā waeine ine rānei (hei tauira, 0.375 inihi, 9.525 mirimita rānei).
Hipanga 1: Tāutuhia ō hiahia:
Hei whakatau i te rahi tika o te mekameka roera, he mea nui kia aromatawaihia ngā whakaritenga o tētahi tono motuhake. Whakaarohia ēnei āhuatanga:
1. Tukunga Hiko: Ka whakatau tata i ngā hiahia hiko o te pūnaha i roto i ngā waeine o te hōpaika (HP) me ngā kilowatt (kW). Ka whakatau i te putanga hiko mōrahi me ngā āhuatanga taumaha pea.
2. Tere: Whakatauhia te tere hurihuri (RPM) o te pīkau taraiwa me te pīkau taraiwa. Whakaarohia te tere whakahaere e hiahiatia ana me ngā rerekētanga tere pea.
3. Ngā āhuatanga taiao: Whakaarohia ngā āhuatanga whakahaere pēnei i te pāmahana, te haumākū, te puehu, tetahi atu mea waikura rānei kei roto.
Hipanga 2: Tātaihia te roa o te mekameka:
Kia whakatauhia ngā whakaritenga, ko te mahi e whai ake nei ko te tatau i te roa o te mekameka e tika ana. Ka whakatauhia tēnei mā te tawhiti i waenga i ngā pokapū o te pīro taraiwa me te pīro taraiwa. Whakamahia te tātai e whai ake nei:
Te roa o te mekameka (pitch) = (te maha o ngā niho i runga i te sprocket taraiwa + te maha o ngā niho i runga i te sprocket taraiwa) / 2 + (te tawhiti pokapū / pitch)
Hipanga 3: Whakaarohia ngā Whakaritenga Taumahatanga:
He mea nui te whakatōtika tika mō te roa me te whai huatanga o ngā mekameka roera. Ki te kore e ranea te whakatōtika, ka paheke te mekameka, ka pakaru wawe, ka whakaiti hoki i te tuku hiko. I tetahi atu taha, ka taea e te whakatōtika nui te whakararuraru i te mekameka, ka nui ake te waku me te pakaru pea. Tirohia te aratohu a te kaihanga hei whakatau i te awhe whakatōtika pai rawa atu mō te rahi me te whakamahinga o tō mekameka.
Hipanga 4: Manatokohia te kaha kawenga:
Ko te kaha kawenga o te mekameka roera ka whakatauhia e tōna rahi. He mea nui kia manatokohia kei te kaha te mekameka kua tīpakohia ki te kawe i te kawenga e tumanakohia ana. He maha ngā wā ka whakaratohia e ngā kaihanga he tūtohi kaha kawenga e whai whakaaro ana ki ngā āhuatanga maha pēnei i te kaha kume, te whānui o te roera me te rauemi. Kōwhiria he mekameka roera e nui ake ana i ngā whakaritenga kawenga o tō tono kia roa ai te ora me te pono.
He mea nui te rahi tika o ngā mekameka roera ki te whakahaere maeneene o ngā pūnaha tuku hiko. Ka taea te whakatau tika i te rahi tika o te mekameka mā te arotake i te mana, te tere, ngā āhuatanga taiao me ngā whakaritenga kume. Kia mahara ki te tirotiro i ngā aratohu a te kaihanga me ngā tūtohi kaha kawenga hei whakarite i te roa me te pono o tō pūnaha. Mā te māramatanga pakari ki te tukanga rahi, ka taea e koe te whiriwhiri māia i te mekameka roera tino pai mō tō tono, ka whakatakoto i te ara mō te whai hua me te mahi tino pai.
