He aha te tohu o te whati o te haurua o te kakau
Mena kei roto i te tukanga o ngā raruraru waka tere-rahi, ka arahi pea ki te wetewete o te potae waka, ki te ngaronga porowhita pokapū rānei, ka arahi te porowhita ngaronga pokapū ki te kore taurite o te taurite hihiri o te motuka, ka wiri te wira urungi tere-rahi o te waka, e mōhiotia ana hoki te toki ko te pou taraiwa. I roto i te pūnaha tuku waka, he mahi nui te pou haurua, ko te wira taraiwa me te pou hononga rerekētanga. Ko te pito o roto ka honoa mā te taputapu me ngā splines haurua-pou, ā, ko te pito o waho ka honoa ki te pokapū me te flange. Ko te hanganga o te wira taraiwa waka ka whakawhirinaki ki te āhua hanganga o te toki. E ai ki ngā āhuatanga rerekē o te kaha o te toki, ka taea te wehewehe ki te toki haurua-mīhini me te toki mīhini katoa. Ka kitea he wāhanga nui te toki waka o te waka i roto i te taraiwa o ia rā, ā, ko te haumaru o te waka ka whakawhirinaki ki te mahi a te toki. I muri i te wā roa o te ngenge torsional me te pānga, ka ngawari te piko, te whati, te torsion, te skew me te spline tooth wear o te toki waka. Ko te whati o te toki waka he maha ngā momo āhua:
① Kua whati te porowhita o te kakau;
(2) He maha ngā pakaru me ngā whatiwhatinga kei te wāhanga o te pou o te haurua-pou;
③ kua whati te spline o te kakau;
(4) he pakaru kei roto i te kōpae orchid haurua-pou, ā, ka taka atu ina tino kino;
(5) Ētahi atu whatiwhatinga āhua me ngā kapiti o te kakau.
