Ngā Pūrongo - He aha te Tukanga Whakamārō o te Mekameka Whakawhiti Hononga Porowhita?

Ka taea te whakapakeke i ngā niho o te mekameka kawe mā te mura, te whakapakeketanga rānei o te aki.

Temekameka porotitiHe tino ōrite ngā hua whakapakeke i puta mai i ngā tikanga e rua, ā, ko te kōwhiringa o tētahi o ngā tikanga e rua e whakawhirinaki ana ki te wātea o ngā taputapu, te rahi o ngā puranga, te rahi o te pītau (pitch) me te āhua o te hua (te rahi o te poka, ngā kōhao i te rohe e pāngia ana e te wera me ngā ara kī).

Mā te whakapakeke i ngā niho ka roa ake te ora o te poroka mekameka kawe, ā, e taunakihia ana mō te whakamahinga roa o te kawe waka, inā koa he raruraru te pakū.

Te pakeketanga o te pakeketanga

Ka whakatauhia tuatahitia tēnei e te rauemi maitai i whakamahia hei hanga i te poro mekameka, engari ka taea te whakaiti i ngā taumata pakeke mā te whakamahana i muri mai kia tutuki ai ngā taumata kua tohua.

Ko te nuinga o ngā porotiti mekameka kawe he mea hanga ki te whakarewa C45 kei roto ko te 0.45% waro. Ko te pakeke o ngā niho whakapakeke o tēnei rauemi he 45-55 HRC, ā, ka taea te whakatikatika ki tētahi taumata pakeke kua tohua i raro iho i tēnei.

Mena e hiahiatia ana kia pai ake te mau o te porotiti mekameka i te mekameka hono porowhita, ko te taumata pakeke kua tohua mō te porotiti he 5-10 ngā tohu HRC iti iho i te mekameka hono porowhita. Ko te pakeke o te porotiti mekameka noa kua tohua mō tēnei momo tono ko te 35-40 HRC.

Te hohonutanga o te pakeke o te pouaka

Ko te hohonutanga mārō noa he 1.5 – 2.0 mm, engari ka taea te whakamahi i ngā tauira hohonu ake mō ngā whakamahinga motuhake.

Rohe Whakapakari o te Mekameka Sprocket

Ko te wāhi nui hei whakapakeke ko te mata o ngā niho pītiti e pā ana ki ngā hononga mekameka. Ka rerekē tēnei i runga i te momo niho pītiti, engari ko te nuinga o te wā ko te wāhi piko o te niho pītiti (arā, te pītiti niho pōke) te wāhi e pā ai ngā hononga mekameka ki te niho. Ko te pūtake o te niho, kāore e taea te pakaru, ā, kāore e hiahiatia kia whakapakeketia, engari ka whakapakeketia hei wāhanga o tētahi o ngā tukanga (mura, whakaawe rānei). Ina kua roa ake te tawhiti o te raina piko, te whakawātea rānei o te pītiti mekameka kawe i tēnei wāhi, kāore e hiahiatia kia whakapakeketia tēnei wāhanga o te niho.
