ʻO nā bearings bulldozer nā ʻāpana mechanical nui i hoʻohana ʻia e kākoʻo i nā ʻāpana wili, hoʻemi i ka friction, a hoʻouna i nā ukana. ʻO ka mea maʻamau i loko o ke apo i loko (ka hoʻopaʻa ʻana me ka shaft), kahi apo o waho (ka hui ʻana me ka hale), nā mea ʻōwili (nā pōpō kila, nā wili, a me nā mea ʻē aʻe), a me kahi hale (e hoʻokaʻawale ana i nā mea ʻōwili). ʻO kāna mea waiwai nui ka carbon chromium e lawe ana i ke kila (e like me GCr15), nona ka paʻakikī kiʻekiʻe (ʻo ka paʻakikī o ka ʻōwili ʻana a hiki i ka HRC60-65), ke kūpaʻa ʻana, a me ke kūpaʻa luhi ma hope o ka mālama ʻana i ka wela. Hiki iā ia ke hoʻololi i nā kūlana hana koʻikoʻi o nā bulldozers e like me ke kaumaha kaumaha, ka haʻalulu, ka lepo, a me nā mea'ē aʻe. E like me keʻano o ka friction, hiki ke hoʻokaʻawaleʻia nā bearings bulldozer i nā bearings rolling (e hoʻemi ana i ka friction ma o nā mea'ōwili a hoʻohana nuiʻia) a me nā bearings sliding (i kākoʻoʻia e ka friction sliding, e like me nā bushings). Ma waena o lākou, ua lilo nā bearings i mea makemake nui e hoʻololi i nā ʻāpana o nā bulldozers ma muli o ko lākou haʻahaʻa friction coefficient a me ka wikiwiki wikiwiki adaptability.1. Kākoʻo i nā ʻāpana hoʻololi Hāʻawi i ka radial a me ke axial positioning no nā ʻāpana shaft (e like me ka drive shafts, gear shafts) e hōʻoia i ka hana paʻa o nā ʻāpana wili (gears, sprockets, etc.) ma nā trajectories i koho mua ʻia, e pale i ka haʻalulu a i ʻole ka hui ʻana ma muli o ka offset. E hoʻohuli i ka ʻāwili hoʻoheheʻe o nā ʻāpana kaʻa i loko o ka friction wili (a i ʻole ka haʻahaʻa friction sliding) ma o nā ʻāpana ʻōwili (a i ʻole nā ʻaoʻao hoʻoheheʻe), e hōʻemi i ka nalowale o ka ikehu i ka wā e hoʻoili ʻia ai ka mana, a hoʻomaikaʻi i ka pono o ka lawe ʻana. E amo i ka ukana radial (e like me ke kaumaha pono'ī o ka lāʻau, ka ikaika radial o ka mīkini meshing) a me ka ukana axial (e like me ka ikaika axial i hana ʻia e ke kī o ka bulldozer shovel) i ka wā o ka hana bulldozer, a e hoʻouna i ka ukana i ka pūpū a i ʻole ke kiʻi e pale i ka deformation pololei o ke kino kumu ma lalo o ka ikaika.
Nā hiʻohiʻona noi maʻamau
I ka hana ana o na bulldozers (e like me ka hookuke ana i ka lepo paa a i ka pii ana paha i na pali), pono na bearings e ku i na haawe nui (e like me ka haawe koke o na huila kaa e hiki aku ana ma mua o 10 tons), no laila, pono ke koho i na bearings me na huina hali ki'eki'e (e like me ka tapered roller bearing and self{1}}hooponopono i ke apo.
2. Anti pollution a sila
He lepo a lepo ka wahi hana, a pono e hoʻohana ʻia nā bearings me nā mea hoʻopaʻa sila (e like me nā sila aila a me nā uhi lepo):
ʻO nā ʻāpana i hōʻike ʻia (e like me ka track drive wheel bearings) e koi i nā sila ʻaila lehelehe pālua a me nā uhi lepo e pale ai i ka lepo a me ke one mai ke komo ʻana i ke ala heihei (hiki i nā haumia ke hoʻoulu i ka "ʻaʻahu abrasive" o nā bearings, e hōʻemi ana i ko lākou ola ma mua o 50%);
ʻO nā bearings i loko o ka pahu pahu e hilinaʻi i ka lubrication a me ka hoʻopaʻa ʻana i ka ʻaila, a he mea pono e hōʻoia i ka leak ʻole o ka pahu pahu.
3. Lubrication a me ka wela
ʻO nā bearings rotating speed kiʻekiʻe (e like me ka gearbox spindle bearings) koi i ka lubrication hoʻoikaika ʻia me ka ʻaila ʻaila (i hoʻopaʻa ʻia ma nā ala ʻaila) e hoʻoneʻe i ka wela frictional (e pale i ka pau ʻole o ka momona i hoʻokumu ʻia e nā wela kiʻekiʻe);
Pono e hoʻomaʻamaʻa mau ʻia nā bearings kaumaha -wikiwiki haʻahaʻa (e like me nā bearings bakeke pine roller) me ka momona (hoʻokahi manawa i kēlā me kēia 200 hola) e hana i kahi kiʻiʻoniʻoni aila a hoʻemi i ka friction.
· Pilikia: ʻAʻole hiki mua ke kākoʻo ʻana i nā huila huila ma muli o ka hopena pōhaku. Hoʻoholo:
Hoʻohana ʻana i ʻekolu lālani o nā bearings wili liʻiliʻi (me ka piʻi ʻana o 50% o ka hiki ke amo)
ʻO ka ʻoi loa o ka Roller Logarithmic Curve (Uniformization of Stress Distribution)
Upgrade lubricating grease to fully synthetic lithium based grease (drip point>260 degere)
2. Kaiapuni kūkulu ʻāina pulu:
· Paʻa: ʻAʻole hiki ke hoʻopaʻa ʻia ma muli o ke komo ʻana o ka wai/sediment · Hoʻolālā hou:
Sila aila lehelehe ʻelua
E hoʻohui i nā kahawai wai i ka noho hili (e like me ka Caterpillar D6T design)
3. Ke hana nei ma nā ʻāpana kiʻekiʻe-:
· ʻAha ʻeha: ʻO ka wela haʻahaʻa o -50 degere C ka mea e paʻa ai ka momona. Hoʻopaʻapaʻa:
ʻO ka momona haʻahaʻa haʻahaʻa haʻahaʻa i hoʻopiha mua ʻia no nā bearings (hiki ke kahe i ka -60 degere C)
E koho i ke kila paʻakikī kiʻekiʻe (Charpy impact energy ʻoi aku ka nui a i ʻole like me 100J)
