Te rakau whēra o te porowhita.
Ko ngā taera e mau ana ki runga i ngā whāriki pumau o te toki porowhita me te poraka rango, ā, e mahi ana hei peera me te whakahinuhinu, e kiia ana he papa peera toki porowhita.
Ko te whāriki porowhita e wehea whānuitia ana kia rua ngā momo: te whāriki me te whāriki flanged. Ehara i te mea ka taea e te anga whāriki flanged anake te tautoko me te whakahinuhinu i te porowhita, engari ka takaro hoki i te tūranga o te porowhita.
kōhao
Me anga ngā kōhao o ngā taera e rua ki te taha kotahi, ā, ki te mea he motuhake te rakau here o te tokotoko hono i ngā taha e rua, me kitea ngā tohu i te taha o te tokotoko hono.
Te roa o te peera
Ka utaina te peera hou ki roto i te kōhao nohoanga, ā, me 0.03-0.05mm te teitei ake o ia pito o ngā wahi o runga me raro i te papa nohoanga peera. Kia piri pai ai te anga peera me te kōhao nohoanga, kia pai ake ai te pānga marara wera.
Ko te tikanga whakamātautau hei tirotiro i te roa o te rakau whīra ko: tāutahia te rakau whīra, tāutahia te taupoki rakau whīra, whakakīia tetahi pūtu pito kia rite ki te uara taipana kua tohua, whakauruhia he gasket he 0.05mm te matotoru ki waenganui i tetahi atu taupoki pito me te papa nohoanga rakau whīra, ina tae te taipana o te pūtu pito tīwiri ki te 10-20N·m, ki te kore e taea te tango i te gasket, he tohu tēnei he roa rawa te roa o te peera, ā, me whakakōkō te pito kāore e tū ana te hononga ki raro; ki te taea te tango i te gasket, he tohu tēnei he pai te roa o te peera; ki te kore te gasket e whakawirihia ki te uara taipana kua tohua, kāore e taea te tango, he tohu tēnei he poto rawa te rakau whīra, ā, me tīpako anō.
He pai te taura maeneene o te tuara
Me noho pūmau te tuara o te peera, ko te taratara o te mata ko te 0.8μm, ka taea e te titi te aukati i te hurihanga o te whitiki peera, ā, ki te iti rawa te titi, ka taea te whakamahi hei pānga ki te teitei pai, ki te kino te titi, me tīpako anō te whitiki peera.
He taunga pīwariwari, kāore he kiri
I muri i te whakatakotoranga o te rakau whīra hou ki runga i te nohoanga whīra, me nui ake te pūtoro piko o te rakau whīra i te pūtoro piko o te kōhao nohoanga. Ina utaina te rakau whīra ki roto i te kōhao nohoanga, ka taea te hono tata ki te kōhao nohoanga whīra mā te puna o te rakau whīra tonu hei whakahaere i te marara o te wera. Tirohia mēnā he koretake te anga whīra, ka taea e koe te pato i te tuara o te anga whīra hei tirotiro, he tangi koretake e tohu ana kāore i te kaha te koranu me te pereti o raro, me tīpako anō.
Me tika te āputa ōrite o te pukapuka tāera poutū.
Ina tīpakohia te anga whāriki, me tirotiro te āputa e ōrite ana. I te wā e tirotirohia ana, ka inehia e te ine rango me te maikoromita te rakau whāriki me te pukapuka, ā, ko te rerekētanga ko te āputa e tau ana. Ko te tikanga tirotiro mō te āputa o te rakau whāriki koia tēnei: mō te tokotoko hono, pania he paparanga hinu angiangi ki runga i te rakau whāriki, whakakīia te tokotoko hono ki runga i te pukapuka e ōrite ana, whakakīia te pūtu kia rite ki te uara taipana kua tohua, kātahi ka hurihia te tokotoko hono mā te ringa, ka taea te huri i te 1 ~ 1/2 hurihanga, ka tōia te tokotoko hono i te taha o te tuaka, kāore he āputa e kitea ana, arā, ka tutuki i ngā whakaritenga; mō ngā shingle crankshaft, pania te hinu ki runga i te mata o ia kaki rakau me ngā shingle crankshaft, tāutahia te crankshaft ka whakakīia ngā pūtu kia rite ki te uara taipana kua tohua, ka tōia te crankshaft ki ngā ringa e rua, kia taea ai e te crankshaft te huri i te 1/2 hurihanga, ā, kia māmā, kia ōrite te hurihanga me te kore e ārai i te āhuatanga.
Te tikanga tāutanga tika o te pereki porowhita
Ko te tāutanga tika o ngā pereki porowhita ko ngā mahi matua e whai ake nei:
Te Tāutanga o te Toka Taurite: Tāutanga he toka taurite ki ia taha o te toka crankshaft. Ka whakawhirinaki ēnei toka taurite ki te hinu tauhiuhi hei whakahinuhinu, kaua ki te whakahinuhinu ā-kaha mā te papu hinu. Nō reira, he mea tino nui te whakahaere i te āputa i waenga i te toka taurite me te anga whīra, ā, me pupuri i waenga i te 0.15-0.20 mm.
Te whakahaere me te whakatikatika i te āputa: Mena he uaua ki te whakahaere i te āputa, ka taea e koe te whakamahi i te taputapu whāwhā hei ine i te āputa i waenga i te rakau whāngai me te pou taurite ina kāore anō te rakau whāngai kia tāutahia ki te poraka rango. Ko te āputa e taunakitia ana ko te 0.3 mm. Mena he iti iho i te 0.3 mm te āputa, ka taea te whakatutuki i te rahi e hiahiatia ana mā te waru, te miihini rānei i runga i te mīhini hurihuri kia 0.05 mm te paerewa pokanoa i waenga i te rakau whāngai me te kōhao whāngai, ā, ko te āputa he tata ki te 0.18 mm i muri i te patohia o te rakau whāngai ki roto i te kōhao whāngai.
Rakau whāriki pumau: I te wā e tāuta ana i te rakau whāriki toki taurite, me tāpiri he kāpia 302AB ki te tuara o te rakau whāriki hei whakanui ake i te pumau o te rakau whāriki, ā, hei ārai i tōna nekeneke, i tōna wetekina rānei.
Te tūnga me te whakahinuhinu o te peera: he puku tūnga kei ia anga peera, me whakapiri ki roto i te mokowā tūnga i runga i te poraka rango. I taua wā anō, me whakarite kia rite te kōhao putanga hinu i roto i te peera ki te putanga hinu i roto i te poraka rango kia pai ai te pūnaha whakahinuhinu.
Te tāutanga o te taupoki peera: Whai muri i te tāutanga o te taupoki peera tuatahi, hurihia te porowhita kia kore ai e mau. Tāutahia he taupoki peera, ā, whakauhia kia rite ki ngā whakaritenga. Ka mahia tēnei mō ia taupoki peera. Mena kua mau te taupoki peera, kei roto pea i te taupoki peera, i te wāhanga peera rānei te raruraru. Tangohia, tirohia mēnā he pūwero, he hē rānei te urunga o te nohoanga peera.
Mā te whai i ēnei mahi, ka taea e koe te whakarite kia tika te tāutanga o ngā taera o te porowhita me te karo i te pakaru miihini nā te tāutanga hē.
