ʻEnuhe Komatsu a me Shantui Sprocket ʻāpana

ʻO nā sprocketsa e holo mau na mahele i ka laina me kakaulahaoka pitch.Inā paʻa ka sprocket a i ʻole ka ʻāpana, ʻoi aku ka ʻoi o nā kiko o ke apo.No ka mea, aia ka pāʻani ma waena o nā pine a me nā lāʻau.ʻO kekahi hiʻohiʻona ʻaʻahu maʻamau no nā sprockets a me nā ʻāpana ʻo ia ka lole lateral.Hoʻokumu ʻia kēia e (ma waena o nā mea ʻē aʻe) nā alakaʻi kaulahao wili, kahi wiliundercarriage, a i ʻole alakaʻi maikaʻi ʻole o ka huila mua.Hiki ke kumu ia ma muli o ka kānana ʻana o nā mea paʻakikī ma waena o nā bushings a me ka cogwheel, a i ʻole ma ke ala pololei ʻole.No ka hoʻopau ʻana i ka ʻaʻahu mai ke komo ʻana o ka lepo (packing), hana mākou i nā notches one i loko o kā mākou sprockets.

I kekahi manawa, ʻoi aku ka ʻoi o nā sprockets a i ʻole ʻāpana ʻāpana o ka mīkini, akā ʻike ʻia nā loulou alahele i ke kūlana kūpono.Nīnau pinepine ʻia mākou inā pono e hoʻololi ʻia nā sprockets.ʻO ke kumu wale nō e ʻoi ai ka ʻoi o ka sprocket ma o ka piʻi nui ʻana o ke kaulahao.ʻO ka hoʻonui ʻana i ka pitch e hoʻonui i ka pāʻani ma waena o ka pine a me ka bushing.ʻO ka hopena, ʻaʻole e holo hou ke kaulahao o ke kaulahao i ka laina me ka ʻāpana puha o ka sprocket.Hoʻopau kēia i nā ʻōpuʻu a lilo nā lae i ʻoi.No laila, mai hoʻololi wale i kahi sprocket.Inā pono e hoʻololi ʻia kahi sprocket mai kahi excavator me nā kaulahao maloʻo, a laila e hoʻololi mau ʻia nā loulou track, a ʻo ia hoʻi.

Ma muli o ka hana ʻana o nā bulldozers i nā hana kelepona he nui, pono lākou i nā kaulahao lubricated aila i hui pū ʻia me nā ʻāpana.Loaʻa ka lole o nā ʻāpana i ke kīʻaha ma waena o nā wahi ʻāpana.Hiki ke hoʻonui wale i ka pitch i ka wā e kahe ai ke kaulahao lubricated aila, a laila e lilo nā kiko o nā ʻāpana.Inā ʻaʻole e kahe ka ʻaila lubricated kaulahao, a laila ʻoi aku ka maikaʻi o ka hoʻololi ʻana i nā ʻāpana ma mua o ka pau ʻana o ka pōʻai;ma ia ala hiki ke hoʻohana ʻia ka undercarriage no kekahi mau haneli mau hola.
