He aha te mahi a te porowhita o te waka
Ko te mahi matua o te porowhita waka he huri i te kaha pana mai i te tokotoko honohono piston ki te kaha taipana hurihuri, kia taea ai te taraiwa i te pūnaha tuku waka me te pūnaha takirere miihini me ētahi atu taputapu āwhina. Ko te porowhita tetahi o ngā wāhanga tino noa me te mea nui o te miihini, ko tana mahi he huri i te pēhanga hau e tukuna ana e te tokotoko honohono piston ki te taipana, ā, ka mahi hei putanga hiko hei taraiwa i ētahi atu tikanga mahi.
Te mahi a te porowhita hurihuri
Ka whakatutukihia e te porowhita te hurihanga me te whakawhiti pūngao mā te huri i te nekehanga raina tauutuutu o te piston ki te nekehanga hurihuri porowhita. Ka tukuna ki raro i ngā kawenga tauutuutu uaua, tae atu ki te mahi a ngā huringa ā-wā i roto i te kaha aerodynamic, te kaha inertial me te moment, nō reira me nui te kaha me te pakari o te porowhita ki te piko me te torsion.
Hanganga me ngā rauemi o te porowhita
Ko ngā poroporo porowhita he mea hanga ki te maitai koranu kaha-teitei, he kaha kume teitei, he pakari hoki. Kei roto i tōna hanganga te kaki o te porowhita matua, te kaki o te tokotoko hono me ētahi atu wāhanga, kua hoahoatia, kua tīpakohia hoki ngā rauemi hei whakarite kia taea e te porowhita te tu atu i ngā kaha nui me te taipana i ngā tere teitei, me te pupuri tonu i te hurihanga pumau.
Te tiaki i te porowhita crankshaft me ngā raruraru noa
Tērā pea ka piko, ka takahuri rānei te poroporo i te wā e whakamahia ana mō ngā take maha, ka pā ki tana mahi noa. Hei whakarite kia mahi noa te poroporo, me tirotirohia me te tiaki i ia wā, tae atu ki te tirotiro i te pakaru, te taurite me te ātea o te poroporo. Ko ngā raruraru tiaki noa ko te piko me te hurihanga o te poroporo, ka arahi pea ki te ngoikore o te mahi a te miihini, te pakaru rānei.
Mēnā ka pakaru te porowhita o te waka, ka taea te whakatika me te whakakapi i ēnei tikanga:
Tikanga whakatika:
Te Hurihuri : Mō ngā pakaru iti, ka taea te tango i tētahi paparanga whakarewa mai i te mata o te porowhita mā te hurihuri hei whakahoki mai i tōna rahi me tōna āhua. Me whai taputapu tino tika me ngā tohunga hangarau ngaio hei whakahaere.
whakarewa : Mena he kapiti kei roto i te porowhita, ka taea te whakatika mā te whakarewa. Heoi, me tino whakahaere te tukanga whakarewa i te pāmahana me te tukanga hei ārai i te whakarerekētanga me te ahotea toenga. Me tukatuka wera me te kimi hapa i muri i te whakarewa.
whakatikatika : Mō ngā poro porotaka piko, ka taea te whakamahi i te pēhi hei whakatika. Ko te tukanga whakatikatika e hiahia ana kia ine tika i te nekehanga me te tūranga o te piko, me te pēhanga āta haere kia hoki mai te āhua tika. Whai muri i te whakatikatika, me kimi hapa me te kimi taurite hihiri.
Tikanga whakarerekē:
Kōwhiria te porowhita tika: Kōwhiria te porowhita tika hei whakakapinga kia rite ki te tauira me te momo miihini o te waka. Me whakarite kia rite te rauemi, te rahi me te mahi o te porowhita hou ki te mea taketake.
tāutanga ngaio : Me whakamahi hangarau me taputapu ngaio hei whakakapi i te poroporo. I te wā o te tāutanga, kia aro ki te taurite o te poroporo, te taurite o te āputa me te kaha whakakī o ngā pūtu kua mau.
tirotiro me te manatoko : Whai muri i te whakakapinga, me whakahaere he tirotiro whānui, tae atu ki te kimi hapa me te taurite hihiri, kia pai ai te mahi a te porowhita, ā, kia kore ai e pā ki te mahi a te miihini.
Ngā mahi ārai:
Te tiaki auau: whakakapia te hinu me te tātari hinu i te wā tika kia pai ai te mahi a te pūnaha whakahinuhinu, kia kore ai hoki e maroke te waku me te kakahu.
tirotiro me te tiaki : tirohia te āhua o te toki porotaka i ia wā, tae atu ki te āputa i waenga i te porotaka me te anga peera, te piko me te hē o te toki porotaka.
karohia te uta nui rawa : karohia te uta nui rawa o te miihini mō te wā roa, whakaitihia te kino i puta mai i te wera nui me te ahotea miihini.
