Ngā wāhanga o te rōpū wira rere o te porowhita hurihuri o te miihini
Tuatahi, te porowhita
Ko te poroporo tetahi o ngā wāhanga tino nui o te miihini, ko tana mahi he tu atu i te pēhanga hau mai i te rōpū tokotoko honohono piston ki te taipana o te poroporo me te putanga o waho, hei tāpiri, ka whakamahia hoki te poroporo hei taraiwa i te pūnaha takirere o te miihini me ētahi atu taputapu āwhina (pēnei i ngā whakaputa hiko, ngā pā, ngā papu wai, ngā papu urungi mana, te pūnaha poroporo taurite, me ētahi atu).
Rōpū wira rere o te toki porowhita: 1- pūrei; 2- wira whitiki niho wā o te toki porowhita; 3- pīkau toki porowhita; 4- Toki Porowhita; 5- whāriki matua o te toki porowhita (runga); 6- Wira rere; 7- Kaihanga tohu pūoko tere; 8, 11- papa pana; 9- whāriki matua o te toki porowhita (raro); 10- Taupoki whāriki matua o te toki porowhita.
Ina mahi te porowhita, me tu atu ki ngā huringa auau o te pēhanga hau, te kaha ā-tauhohe me te kaha ā-pokapū, tae atu ki tōna taipana me te nekehanga piko i raro i te mahi tere-teitei, he ngāwari ki te piko me te takahuri i te āhua rerekē, nō reira, me nui te kaha me te pakari o te porowhita, he ātete pai ki te kakahu me te taurite pai. Ko te porowhita he mea hanga i te maitai koranu waro-waenga, ā, ko te mata o te porowhita ka tukatukahia e te tinei auau-teitei, te nitriding rānei. Ko te porowhita miihini Shanghai Santana he mea hanga ki te maitai waro-waenga kounga teitei te hanga mate. Ko ngā miihini Audi JW me Yuchai YC6105QC he mea hanga ki te rino whenua onge iti te utu, kaha-teitei me te ātete kakahu pai.
1. Hanganga o te porowhita
Ko te poroporo cranks he mea hanga i te pito o mua, i te kaki o te pou matua, i te poroporo, i te taumaha taurite, i te pukapuka tokotoko hono me te pito o muri. Ko te poroporo he mea hanga i te pukapuka tokotoko hono me ōna pukapuka matua maui me matau. Ko te maha o ngā poroporo o te poroporo cranks e whakawhirinaki ana ki te maha me te whakaritenga o ngā rango. Kotahi anake te poroporo o te poroporo o te miihini rango kotahi; Ko te maha o ngā poroporo o te poroporo cranks o te miihini in-line he rite ki te maha o ngā rango; Ko te maha o ngā poroporo i roto i te poroporo cranks o te miihini V he rite ki te haurua o te maha o ngā rango. Ko te pou o mua o te poroporo cranks he pūrei, he taputapu taima, me ētahi atu, e whakamahia ana hei taraiwa i te papu wai me te tikanga takirere. Ko te kaki poroporo o te poroporo cranks kua whakauruhia ki te nohoanga matua o te tinana rango, ā, e whakamahia ana hei tautoko i te poroporo cranks. Ko te pukapuka tokotoko hono ka whakamahia hei tāuta i te tokotoko hono, ā, ka hono te poroporo i te pukapuka pou matua ki te pukapuka tokotoko hono. Hei whakataurite i te kaha o te pūwero ina huri te porowhita, ka whakaratohia he poraka whakataurite ki runga i te porowhita. Ka whakaratohia he hononga hononga ki te pito o muri o te porowhita hei hono i te wira rere ki te porowhita mā te whakamahi i ngā pūtu. Hei whakahinuhinu i te pukapuka tokotoko hono, ka pokaia he ara whakahinuhinu mai i te pukapuka tokotoko matua ki te pukapuka tokotoko hono. He māmā te hanganga o te porowhita whakauru, he māmā te taumaha, he pono te whakahaere, ā, he whānuitia te whakamahi i ngā peera papatahi, e whakamahia whānuitia ana i roto i ngā miihini reo-rahi me te iti.
2. Te kaupapa whakatakotoranga o te porowhita
Ko te āhua o te porowhita me te tūranga ōrite o ia porowhita e whakawhirinaki ana ki te maha o ngā rango, te whakaritenga o ngā rango me te raupapa mahi o ia rango. I te whakaritenga o te raupapa mahi a te miihini, me whai i ēnei ture i ngā wā katoa e taea ana:
Me whakarite kia tawhiti rawa ngā rango e rua o te mahi tonu kia iti ake ai te kawenga o te peera matua, kia kore ai hoki e tuwhera ngā takirere hono e rua i te wā kotahi i te wā e whakauru ana, ā, ka pā te āhuatanga o te "hopu hau" ki te pai o te pupuhi o te miihini.
(1) Me ōrite te koki wā mahi o ia rango hei whakahaere i te maeneene o te mahi a te miihini. I roto i te koki o te toki porowhita e oti ai te huringa mahi a te miihini, me mahi kotahi ia rango. Mō te miihini wha-whiu me te nama rango i, ko te koki wā mahi he 720°/i. Ara, me whai rango ia 720°/i o te toki porowhita hei mahi kia maeneene ai te oma o te miihini.
(2) Mena he mīhini momo-V, me mahi tauwhitiwhiti ngā pou maui me ngā pou matau o ngā rango.
3. Te whakaritenga noa o te porotaka miihini maha-puoto me te raupapa mahi
Ko te whakaritenga o te porowhita me te porowhita o te miihini wha-whiu-in-line. Ko te koki mahi o te miihini wha-whiu-in-line e wha-puoto he 720°/4=180°, ko ngā porowhita e whā kei te papa kotahi, ā, ko te raupapa mahi a te miihini (te raupapa mura rānei) he 1-3-4-2, 1-2-4-3 rānei. Ko te taputapu pana huringa mahi e whakamahia whānuitia ana he papa pana haurua-porowhita kotahi-taha me te paparanga konganuku ārai-waku, ko te peera matua o te porowhita me te whitiki me te mowhiti pana porowhita e toru ngā āhua. Ko te papa pana he pepa maitai haurua-mowhiti me te paparanga koranu ārai-waku i waho, e tāutahia ana ki te awaawa o te tinana, ki te taupoki peera matua rānei. Hei ārai i te hurihuri o te papa pana, he pupuhi kei te papa pana e mau ana i roto i te awaawa. Ko ētahi papa pana e whakamahi ana i ngā wahi e 4 hei hanga i ngā rohe porowhita pai e rua, ā, ko ētahi e whakamahi ana i ngā wahi rohe e 2. Ko te taha me te konganuku ārai-waku me anga ki te porowhita.
