Introduction to bulldozer bearings ʻO nā bearings bulldozer e pili ana i nā ʻāpana mechanical precision i hoʻohana ʻia i loko o nā bulldozers (he mīkini ʻenekinia kaumaha i hoʻohana ʻia no ka hana honua) no ke kākoʻo ʻana i nā ʻāpana wili, hoʻemi i ka friction, kūpaʻa i nā ukana (radial, axial, a i ʻole hui pū ʻia), a hōʻoia i ka hoʻololi pololei ʻana a i ʻole ka neʻe laina laina o nā mea. ʻO ia nā ʻāpana kumu nui e hiki ai i nā hana koʻikoʻi o ka hoʻoili mana bulldozer, ka hele wāwae, ka hoʻokele, a me ka hana ʻana o ka mea hana (shovel) ʻO nā bearings bulldozer nā ʻāpana kumu e hōʻoia ai i ka hana maikaʻi, hilinaʻi, a lōʻihi -ka hana ʻana o kēia "steel behemoth" i nā kaiapuni ʻino loa. ʻO kā lākou hoʻolālā a me kā lākou koho ʻana e pili pono ana i nā pilikia koʻikoʻi o ka ukana kaumaha, ka hopena, ka pollution, a me ke ola lōʻihi. Mai nā huila kākoʻo o ke ala lepo, a hiki i nā huila hoʻoili e kū nei i nā tausani o ka ikaika, a i nā hui lauwili ʻoluʻolu, nā ʻano bearings like ʻole (ʻoi aku ka tapered roller bearing, spherical roller bearing, a me nā bearings hui). He mea koʻikoʻi ka hoʻomaopopo ʻana i kā lākou mau hiʻohiʻona a me nā noi no ka hoʻolālā ʻana, ka hana ʻana, ka mālama ʻana, a me ka ʻike hewa o nā bulldozers. ʻO ke koho ʻana i -ʻano kiʻekiʻe, kūpono, hoʻokomo pono a mālama ʻia nā bearings kekahi o nā kumu nui i ka hōʻoia ʻana i ka hele ʻana a me ka maikaʻi o ka hana o nā bulldozers.
Aia nā ʻano like ʻole o nā bearings i hoʻohana ʻia ma nā bulldozers, a hiki ke koho ʻia e like me nā wahi kikoʻī a me nā koi hana
1. * * Huina huila conical:**
** * Nā hiʻohiʻona: * * Hiki ke kū i nā ukana radial nui a me nā ukana axial unidirectional i ka manawa like, me ka rigidity kiʻekiʻe a me ka hoʻoponopono maʻalahi o ka hoʻomaʻemaʻe.
** * Noi: * * * Ka iwi kuamoʻo o ka ʻōnaehana hele wāwae * *! Hoʻohana nui ʻia no ke kākoʻo axle o nā huila track, nā huila idler, nā huila alakaʻi, a me nā huila kaʻa. Hoʻohana maʻamau ia i nā ʻōnaehana hoʻouna e like me nā pahu pahu, nā ʻokoʻa, a me nā hoʻokele hope (sprockets).
2. * * Huina huila poepoe:**
** * Nā hiʻohiʻona: * * Hoʻolako ʻia me nā wili lālani ʻelua, ʻo ia ka mea nui e halihali i nā haʻawe radial a hiki ke kū i kekahi mau haʻawe axial bidirectional. ʻO ka pōmaikaʻi nui, ʻo ia ka * * kikowaena kikowaena * *, hiki ke hoʻopaʻi i kekahi degere o misalignment ma waena o ke kumu a me ka noho ʻana, a he kūʻē ikaika i ka haʻalulu a me ka hopena.
** * Hoʻohana: * * Hoʻohana mau ʻia no nā ʻāpana e amo ana i nā haʻahaʻa radial nui a me ke kuhi hewa ʻole a haʻalulu paha, e like me nā kumu sprocket hoʻokele, kekahi mau ʻāpana hoʻokele hope, kekahi mau huila kākoʻo nui, idlers, a me kekahi mau ʻāpana hui o * * mea hana (shovels) * *.
3. * * Nā bearings pōpopo hohonu:**
** * Nā hiʻohiʻona: * * Hiki ke kū i nā ukana radial, akā hiki nō hoʻi ke kū i kekahi mau haʻahaʻa axial bidirectional, me ka coefficient friction haʻahaʻa, kiʻekiʻe ka wikiwiki, a me ke kumu kūʻai waiwai.
** * Hoʻohana: * * Hoʻohana maʻamau i nā ʻāpana kōkua me ka ikaika haʻahaʻa a me ka wikiwiki kiʻekiʻe, e like me nā huila alakaʻi o nā mīkini hoʻopaʻapaʻa, nā pā, nā paila wai, nā mea hana, nā pamu hydraulic/motors (non main drive), etc.
4. * * Nā bearings poepoe pili kihi:**
** * Nā hiʻohiʻona: * * Hiki ke kū i nā ukana axial unidirectional nui, a me nā ukana radial (e hana mau i ka manawa like me nā ukana axial).
** * Hoʻohana: * * Hoʻohana nui ʻia i nā kūlana kahi e koi ʻia ai ka mana pololei o ka neʻe ʻana axial a i ʻole ka lawe ʻana i nā ukana axial maʻemaʻe nui, e like me ke kūlana axial o kekahi mau shafts, nā hoʻokele hoʻokele, a me kekahi mau paila hydraulic i loko o ka pahu pahu.
5. * * Huina huila poepoe:**
*Nā hiʻohiʻona: E like me nā bearings spherical roller, loaʻa iā ia ka -hana hoʻopololei, akā ʻo nā mea ʻolokaʻa he mau wili, no laila, ʻoi aku ka kiʻekiʻe o ka ukana radial-
** * Noi: * * Hoʻohana ʻia i kekahi manawa ma ke ʻano he pani no nā bearings spherical roller ma nā wahi koʻikoʻi -ʻoihana e koi ana i ka hiki ke hoʻouka radial kiʻekiʻe a me ke kaulike.
Nā wahi noi kumu
ʻO ka lawe ʻana o ka bulldozer ke kī i ka hoʻouna ʻana a me ke kākoʻo ʻana o ka mīkini holoʻokoʻa, a pili pono i:
Mekani hele wāwae: Pono ka huila kaʻa a me nā huila alakaʻi o ka bulldozer i hoʻopaʻa ʻia e pale i ke kaumaha o ke kaʻa holoʻokoʻa a me ka ikaika friction o 3.
Mea hana: ʻO ke kuʻekuʻe o ka bulldozer lifting hydraulic system e hoʻomalu i ka hoʻoponopono ʻana i ka ʻokiʻoki a me ka lawe ukana.
Pūnaehana mana: Pono nā bearings i ka pilina ma waena o ka mīkini a me ka pahu pahu e hoʻololi i nā kaiapuni kiʻekiʻe a me ka vibration.
ʻOihana Hoʻonui Waiwai
Ma waho aʻe o nā bulldozers, hoʻohana nui ʻia nā bearings like i:
ʻO ka hana mana hydroelectric: ʻO nā bearings kūikawā no nā pani puka me ke anawaena ma mua o 51cm;
ʻEleʻe kaʻa kaʻa: ma ke ʻano he mea hōʻailona no ka hoʻomohala ʻana i nā kūlana palekana o ka ʻoihana;
Mea hana kūikawā: Nā kakaka pana, -mekini hana kai hohonu a me nā lako kaiapuni koʻikoʻi ʻē aʻe.
ʻO nā manaʻo koho a me ka mālama ʻana no nā bearings bulldozer
Koho koho
ʻAno hoʻouka: Ke koho ʻia ka haʻahaʻa axial i ka ukana nui, koho ʻia nā bearings thrust, a inā ʻo ka ukana radial ka ukana nui, koho ʻia nā bearings roller;
Kūlana hana: Ua makemake ʻia nā bearings material composite (kū i ka +165 degere) no nā kaiapuni wela kiʻekiʻe, a koho ʻia nā mea kila kuhili no nā kaiapuni ʻino;
Hoʻohālikelike kikoʻī: E ʻike i ka mana bulldozer (e like me nā mīkini liʻiliʻi ma lalo o 37kW a me nā mīkini nui ma luna o 250kW) e koho i ka pae ikaika kūpono o ka bearing 6.
Nā wahi mālama
E nānā mau i ka wela o ka lawe ʻana (e emi iho a like paha me ka 70 degere) a me ka walaʻau ʻino e pale aku i ka luhi waiwai i hoʻokumu ʻia e ke kaumaha;
ʻAʻole pono nā bearings lubricating ponoʻī i ka hoʻokomo ʻana i ka momona pinepine, akā pono ia e pale aku i nā mea haumia o waho mai ke komo ʻana i ka ʻae 1;
I ka hoʻololi ʻana i nā bearings, pono e hōʻoia i ka pololei o ka hoʻopili ʻana i ka hoʻopili ʻana i mea e pale aku ai i ka ʻaʻahu hou i kumu ʻia e ka looseness.
