Mō ngā motuka poutū kei reira te kaha tuaka e noho pūmau ana, ko te nuingangā peera pōro whakapā kokie whakamahia ana, arā, ko te kaha kawe kawenga tuaka o te tinana kawe ka whakamahia hei whakataurite i te kaha tuaka ki raro i hangaia e te taumaha o te rotor o te motuka poutū.
I roto i te hoahoa hanganga o te pūnaha whāriki motuka, ko ngā whāriki pōro whakapā koki te mahi i te whakataurite i ngā kaha tuaka me te whakanoho i ngā whāriki i te wā kotahi; ahakoa kei runga ake, kei raro rānei ngā whāriki pōro whakapā koki, kei te whakataurite ngā whāriki i te tuaka whakararo i hangaia e te taumaha ake o te rotor. Ko te kaha, arā, ina tāutahia te whāriki pōro whakapā koki ki te pito o raro o te motuka, ka piki ake te whāriki i te rotor; ā, ina tāutahia te whāriki ki te pito o runga o te motuka, ka kukume te whāriki i te rotor. Nō reira, mō ngā motuka poutū, he huinga whāriki pōro whakapā koki rarangi kotahi te nuinga o te wā e whakamahia ana.
Mai i te tātaritanga ariā, ka taea e ngā peera rarangi kotahi te tu atu ki ngā kawenga radial me ngā kawenga axial kotahi-ara. Ko ngā koki whakapā paerewa o tēnei momo peera he 15°, 25° me te 40°. Ko te nui ake o te koki whakapā, ko te nui ake o te kaha ki te tu atu i te kawenga axial. Heoi, ko te iti ake o te koki whakapā, ko te pai ake mō te hurihanga tere-teitei. Nō reira, i te wā e whiriwhiri ana i te koki whakapā peera, me whai whakaaro whānui ki te tere o te motuka.
E rua ngā hanganga o ngā peera pōro whakapā koki rarangi rua: kotahi te mowhiti o waho me ngā mowhiti o roto e rua, me tētahi mowhiti o waho me tētahi mowhiti o roto. I roto i te hanganga, e rua ngā peera pōro whakapā koki rarangi kotahi kua honoa ki muri hei tohatoha i te mowhiti o roto me te mowhiti o waho, ka taea te pikau i te kawenga radial me te kawenga axial rua-ara. Ko te nuinga o tēnei momo peera e whakamahia ana i roto i ngā miro taputapu mīhini, ngā motuka auau-teitei, ngā tāpoi hau, ngā papu hinu, ngā pēhi hau, ngā mīhini tā, me ētahi atu.
I roto i ngā mahi whaihua, ka taea e te huinga tuara-ki-tuara (DB) me te huinga kanohi-ki-te-kanohi (DF) o ngā peera whakapā koki kotahi-rārangi, me ngā peera rarangi-rua, te pikau i ngā kawenga radial me ngā kawenga tuaka rua-ara. Ko te huinga peera whakapā koki kotahi-rārangi (DT) kua whirihorahia i roto i te raupapa he pai anake mō ngā mahi kei reira te kawenga tuaka kotahi-ara, ā, kāore i te rawaka te kawenga whakatauranga o te peera kotahi.
I roto i ngā āhuatanga tono tūturu o te motuka, hei tāpiri atu ki te kaha tuaka i te wā e whakahaerehia ana te motuka, mena me whai whakaaro ki te hē o te pokapū o te pou i puta mai i ngā āhuatanga piko pēnei i te pou, i te whare rānei, ka taea hoki te whakamahi i ngā peera porowhita.
