Ngā Hononga Porowhita-Kati o te Mekameka Roera: He aha te mea e pai ake ai te Tau Taurite o ngā Hononga?
I roto i ngā pūnaha tuku hiko ā-ahumahi, ko ngā mekameka roera, hei taputapu tuku hiko whai hua, pono hoki, e whakamahia whānuitia ana i roto i te whānuitanga o ngā mara, tae atu ki te hanga mīhini, ngā taputapu ahuwhenua, me ngā mahi whakahaere. Ki ngā kaihoko, ko te whiriwhiri i tētahi mekameka roera me ngā tawhā tika e pā tika ana ki te pai o te mahi a ngā taputapu, ngā utu tiaki, me te roa o te ratonga. Ahakoa te āhua māmā noa iho te whiriwhiri i te tapeke o ngā hononga i roto i tētahi mekameka porowhita-kati, kei roto tonu he arorau hangarau nui. E whakaae ana te umanga he pai ake te maha o ngā hononga mō ngā mekameka roera. Ehara tēnei whakatau i te mea tūpono noa; e hangai ana ki te whakaaro whānui ki ngā āhuatanga hanganga mekameka, te pai o te tuku, me te roa o te ratonga.
I. Ngā Kaupapa Taketake o te Hanganga me te Hononga o ngā Mekameka Roera
Hei mārama ki te ariā matua o te kōwhiringa hononga, me mārama tuatahi ki te hanganga taketake o te mekameka roera. Ko te mekameka roera paerewa he mea hanga ki ngā pereti o roto, o waho hoki, ngā pine, ngā pū, me ngā roera. Ka taurite ngā pine me ngā pū kia taea ai te huri ngāwari o ngā hononga tata. Ina hanga he mekameka i tētahi porowhita kati, me hono ngā hononga hei whakau i ngā pito. E rua ngā tikanga hononga noa:
Ngā hononga honohono noa (mō ngā hononga taurite anake)
He mea tito mai i te pereti hononga o waho, te pereti hononga o roto, me te pine, ka herea te pine ki te topenga puna, ki te pine cotter rānei. He rite tonu tōna hanganga ki te hononga noa, ā, he wāhi kati noa iho i te wā e huihui ana.
Ngā hononga whakawhiti (mō ngā hononga tau-tauhou anake)
Ina tauhou te maha o ngā hononga katoa, me whakamahi ngā hononga whakawhiti. He pereti hononga o waho tō ēnei hononga kua piko katoa, ā, me hono tahi ngā hononga o roto me o waho i te wā kotahi. Ka rerekē ngā āhuatanga kawenga i ngā hononga noa.
II. Ngā Painga Matua o ngā Mekameka Tau-Taurite: Mai i te Mahi Ā-Mīhini ki te Uara Whaihua
1. Te karo i ngā hononga whakawhiti, te whakapai ake i te kaha whānui
He mea kino ngā hononga whakawhiti mō te mekameka tau-tauhou, engari he nui ngā ngoikoretanga hanganga e pā ana ki a rātou:
Me tu atu ngā pereti hononga o waho o ngā hononga whakawhiti ki te ahotea piko, engari ko ngā hononga tuku iho me tu atu ki te ahotea kume anake. Ko te mutunga iho, ko ngā hononga whakawhiti he ngoikore ake i te 15%-20% i ngā hononga paerewa.
I raro i ngā āhuatanga tere-nui, taumaha rānei, ka ngāwari te huri o ngā hononga whakawhiti hei ngoikore. I roto i te wā, ka pakaru, ka pakaru rānei, ka roa ai te wā e kore ai e mahi ngā taputapu, ka puta rānei he aituā.
Mā te whakamahi i te mekameka tau-taurite ka whakakorea rawatia ngā hononga whakawhiti, ka whakarite kia ōrite te tohatoha kawenga puta noa i ngā hononga katoa, ā, ka whakapai ake i te kaha o te mekameka ki te pikau kawenga me te ātete ki te ngenge.
2. He iti ake te ru o te tuku me te iti iho o te kakahu
I te wā e tukuna ana ngā mekameka roera, ka pāngia ngā mekameka roera e ngā kawenga ru i ia wā ina honoa ngā hononga mekameka me ngā niho porotiti. He rite tonu ngā hononga o ngā hononga mekameka taurite ki te hanganga hononga mekameka tuku iho, ā, ka nui ake te tohatoha pānga i te wā e honoa ana. Heoi, mā ngā hononga whakawhiti āhua koretake ka ngaro pea te tika o te hono i te rohe, ka nui ake te kakahu o ngā roera, ngā pūkaha, me ngā niho porotiti, ka whakapoto i te roa o te ora o te mekameka me te porotiti.
3. Te Tāutanga me te Tiaki Whakangāwari, te Whakaiti i ngā Utu
He māmā ake te hono me te whakahaere i ngā hononga mekameka taurite. Ka taea te tāuta me te tango wawe i ngā hononga honohono paerewa mā te whakamahi i ngā taputapu paerewa, ā, kāore e hiahiatia he tikanga motuhake.
Me tino tika te whakahāngai i ngā hononga whakawhiti i te wā e tāuta ana, ki te kore ka ngāwari te peka ke o te mekameka, ā, ka uaua ake te tiaki.
Mai i te tirohanga roa, he iti ake te tere rahunga o ngā hononga mekameka taurite, ā, he roa ake ngā huringa whakakapinga, ka whakaiti i te wā kore mahi o ngā taputapu me te whakapaunga o ngā wāhanga e manawapa ana, ka whakaiti ā-kore i ngā utu whānui mō te kaihoko.
4. Hototahi ki ngā sprockets paerewa, e whakapai ake ana i te pai o te tuku
Ko ngā porotiti ahumahi he mea hanga ki te taurite, ki te taukē rānei o ngā niho, engari me ōrite ngā auau honohono o te porotiti me te mekameka kia kore ai e pāorooro. Mā ngā mekameka he taurite te maha o ngā hononga ka puta he huringa honohono pumau ake me ngā porotiti, ka whakaiti i ngā rerekētanga tere i puta mai i ngā hononga me ngā niho porotiti kāore i te ōrite, ā, ka whakapai ake i te pai o te tuku mā te 3%-5%. He tino pai ēnei mō ngā taputapu e hiahia ana ki te tika tere teitei (pērā i ngā raina kawe tika me ngā mīhini tā).
III. Ngā Whakaaro mō te Whakamahinga Whaihua
Te Whakataurite i te Tau o ngā Hononga me te Tawhiti Pokapū
I te wā e whiriwhiri ana i tētahi mekameka he taurite te maha o ngā hononga, whakaarohia te tawhiti pokapū o te taputapu. Mena he pumau te tawhiti pokapū, whakatikatikahia te maha o ngā hononga (he pai ake ngā tau taurite) kia tika ai te kume o te mekameka. Mena me ōrite te maha o ngā hononga ki te tawhiti pokapū, whakatikatikahia te tūranga o te sprocket, whakamahia rānei he whakakume hei āwhina.
Te Whakahaere Ngāwari i ngā Tikanga Mahi Motuhake
I ngā āhuatanga onge (pērā i te whakahou i ngā taputapu tawhito, i ngā pūnaha tuku kore-paerewa rānei) ina kore e taea te karo i te mekameka hononga tau-tauhou, tīpakohia ngā hononga whakawhiti kaha-teitei (pērā i ngā pereti maitai koranu kua whakakākahuria) ka whakaitihia te kawenga kua whakatauria mā te 20% hei whakapoto i ngā wā tiaki. Te Whakaū i ngā Tawhā i te Wā Hoko
I te wā e kōrero ana ki ngā kaiwhakarato, he mea nui kia mārama te whakamārama i ngā āhuatanga mahi o te taputapu (tere, kawenga, pāmahana taiao, me ētahi atu) me te maha o ngā hononga mekameka e hiahiatia ana. Ka tūtohu ngā kaiwhakarato kounga teitei i te otinga tino pai i runga i ēnei tawhā, kia kore ai e puta ngā raruraru mahi i puta mai i te maha koretake o ngā hononga mekameka.
IV. He aha me aro atu ai ngā kaihoko ki tēnei taipitopito?
Ki ngā kaihoko, ka pā tika te maha o ngā hononga mekameka ki te pono o ngā taputapu me te utu whānui:
Ka taea e ngā kamupene whakaputa te mate moni e mano yuan ia haora nā te wā kore mahi i puta mai i te whati o te mekameka.
He ngāwari ake te pakaru o ngā taputapu o waho pērā i ngā mīhini ahuwhenua e whakamahi ana i ngā hononga whakawhiti i ngā taiao puehu, makuku hoki, ka piki ake ai ngā utu whakatika.
Me tutuki ngā kaihoko taputapu kaweake i ngā paerewa o te ao (pēnei i te ISO 606 me te ANSI B29.1). Ko te nuinga o ngā paerewa o te ao e taunaki ana kia whakamahia ngā mekameka he taurite te maha o ngā hononga hei kaupapa matua, kia whakaitihia ai ngā mōrearea o te tutuki i ngā whakaritenga i roto i te hokohoko.
