ʻO ka slewing bearing o ka crane crane he "hui" koʻikoʻi o ka crane, no laila he mea nui ka mālama ʻana.ʻO kekahi o nā hiʻohiʻona hana o nā cranes he neʻe intermittent, ʻo ia hoʻi, nā ʻano hana like o ka hoʻihoʻi ʻana, ka neʻe ʻana, ka hoʻokuʻu ʻana a me nā hana ʻē aʻe i loko o ke kaʻina hana e hana like.ʻO ka hoʻomohala ʻana a me ka hoʻohana ʻana i nā cranes ma ka mākeke ke ulu a nui aʻe.E kamaʻilio kākou e pili ana i ka mālama ʻana i ka slewing bearing o ka crane.

I ka hana ʻana i nā hana mālama, ʻo ka mea mua, e noʻonoʻo i ka pilikia o ka huki ʻia ʻana i loko o ka rotary pinion (Gear), a me ka pilikia o ka ʻoki ʻana a me ka ʻako ʻana.He māmā ka ikaika hana o ka crane cantilever.Hoʻokumu ʻia ka crane me kahi kolamu, kahi mea hoʻokele rotary arm rotary a me kahi hoist uila.Hoʻopaʻa ʻia ka ʻaoʻao haʻahaʻa o ke kolamu ma ke kahua paʻa e nā bolts heleuma, a ʻo ka hoʻololi ʻana i ka cantilever e alakaʻi ʻia e kahi mea hoʻemi cycloidal pinwheel.Holo ka lāʻau i ka laina pololei mai ka hema a i ka ʻākau a hāpai i nā mea kaumaha.ʻO ka jib o ka crane he hale kila hollow, he māmā i ke kaumaha, nui ka span, nui i ka hiki ke hoʻokiʻekiʻe, waiwai a paʻa.I ka wā o ka nānā ʻana a me ka mālama ʻana, pono ia e hōʻoia i ka wā e hoʻomaka ai ka mīkini e hana i ka hana slewing a me ka luffing pono, ʻaʻole nā ​​limahana mālama (wéi xiu) i loko o ka pōʻino ma waena o ka boom nui, ke kaʻa hoʻouka a me ka roller, a i ʻole. e iho ana i ke kaa a me ka huila.ʻO ka ʻāpana pōʻino ma waena, koe wale nō ka mea hana crane (i loko o ke kaʻa (loko)).

ʻO ka nānā ʻana i nā bolts bearing slewing (hoʻohui ʻia: poʻo a me ka screw)

1. Ma mua o kēlā me kēia hana o ka crane a i ʻole ma ka liʻiliʻi hoʻokahi o ka pule, e nānā pono i nā bolts ma ka slewing bearing (composition: head and screw);

2. Ma hope o 100 mau hola hana o ka hana mua o ka slewing bearing, e nānā inā ua hemo nā bolts (composition: head and screw), a nānā hou i ka hola hana 300;ma hope o kēlā, e nānā i kēlā me kēia 500 hola hana;I kēia hihia, pono e hōʻemi ʻia ka mamao o ka nānā ʻana.

3. Pono e hoʻopiha ʻia ka slewing bearing me ka ʻaila lubricating-based lithium ma mua o ke kau ʻana;

4. I ka wā e pani ai i nā bolts (composition: head and screw), "hoʻomaʻemaʻe" i nā bolts, e hoʻopili i ke kaula hoʻopaʻa paʻa, a laila hoʻopaʻa iā lākou;E hoʻohana i ka crane e like me nā koi o ka manual hana a me ka papa ikehu crane, A i ʻole e nānā mau i nā bolts paʻa e like me nā koi, hiki iā ʻoe ke pale i ka pōʻino o ka pōʻino luhi.ʻO ka crane cantilever he mea ʻenehana a he crane māmā.Aia i loko o ke kolamu, kahi mea hoʻokele lima slewing a me kahi hoist uila.Loaʻa iā ia ke kaumaha maʻalahi, ke ākea nui, ka hiki ke hoʻokiʻekiʻe nui, ka waiwai a me ka lōʻihi.

Nānā maʻamau o nā Bearings Slewing

1. E nānā i ka maʻalahi o ka hoʻololi ʻana ma ka papa manawa;inā loaʻa ka walaʻau (dB) a i ʻole ka hopena, pono e hoʻōki koke ʻia no ka nānā ʻana, hoʻoponopono pilikia, a me ka wehe ʻana inā pono;

2. E nānā mau i ka naha a i ʻole ka pōʻino o ke apo kaʻa kaʻa, a inā he occlusion, gnawing, ʻili ʻili o ka niho, etc.;

3. E nānā i ke kūlana o ka sila i ka manawa.Ināʻikeʻia ka sila ua pōʻino, pono e hoʻololi i ka manawa.Inā ʻike ʻia ua hāʻule, pono e hoʻonohonoho hou i ka manawa.Ua uhi ʻia ka ʻili niho o ka lubriCATion slewing bearing ring gear me ka ʻaila anti-rust ma mua o ka haʻalele ʻana i ka hale hana.ʻO ka manawa kūpono o kēia anti-rust he 3 a 6 mau mahina.Ma hope o ka hala ʻana o ka manawa kūpono, pono e hoʻopili ʻia ka aila anti-rust i ka manawa.

Lubricate i ke ala heihei o ka slewing bearing

Pono e hoʻopiha ʻia ke ala heihei me ka lubriCATion grease ma ka papa manawa e like me ke kaiapuni hana.Ma hope o 50 mau hola hana no ka manawa mua, pono e hoʻopiha ʻia ke alanui heihei me ka ʻaila lubricating (LubriCATing oil), a laila i kēlā me kēia 300 hola hana ma hope o kēlā.Pono e hoʻopiha ʻia ka slewing bearing me ka momona ma mua a ma hope o ka waiho ʻana no ka manawa lōʻihi.Inā hoʻohana ʻia nā mea hoʻomaʻemaʻe mahu a i ʻole nā ​​pahu wai paʻa no ka hoʻomaʻemaʻe ʻana i ka crane, pono e mālama ʻia ʻaʻole e komo ka wai (Osmosis) i nā loulou slewing ring, a laila pono e lubricated nā pili apo slewing.

Pono e hoʻopiha ʻia ka ʻaila me ka slewing bearing e holo mālie.Ke hoʻopiha ʻia ka momona CATion lubri mai ka sila, hōʻike ia ua pau ka hoʻopiha ʻana.ʻO ka momona momona e hana i kahi kiʻiʻoniʻoni a hana e like me ke sila.
