ʻO ke apo slewing apo ka mea nui i haku ʻia me ke apo luna, ke apo haʻahaʻa a me ka pōpō hoʻopiha piha.Hoʻohana ʻia ka hoʻolālā holoʻokoʻa o ke apo slewing no ka hoʻololi ʻana i nā hopena i nā haʻahaʻa haʻahaʻa a me nā ukana māmā.ʻO nā manaʻo hoʻolālā hoʻokahi-lālani a ʻelua-lālani, a me ka maʻalahi o nā lua kau kau mua.

I ke ola maoli o ka slewing bearing, hiki ke hoʻomalu ʻia ka ʻokoʻa kaumaha o ka blanking anuanu ma 1%, ʻo ka hohonu o ka hāʻule ʻana he 0.5mm, ʻoi aku ka liʻiliʻi o ka maka hope ma mua o 2 ° 30, a ʻo ka ʻokoʻa kaumaha no ka blanking wela i loko o 2%, a ua hili ka helehelena hope He emi iho ka degere ma mua o 3°.

E kaohi i ka make ʻako, ʻo ia hoʻi, e kaohi i ka warpage, ka neʻe ʻana o ke axial, a ʻoki i ka palahalaha ʻana o ka pā ma ka radial tightening.Hoʻopaʻa ʻia kekahi o kēia mau ʻano ma ka hopena pahi paʻa, a paʻa kekahi ma ka ʻaoʻao o ka pahi paʻa a me ka hopena pahi hoʻoneʻe.ʻO ke ʻano o ka hoʻopaʻa ʻana e pili ana i ke ʻano cylinder a me ka pilina mīkini.

ʻO ka slewing bearing he ʻelele rolling bearing me kahi ākea o ka hoʻohana.Hoʻohana ʻia ia no ka hana kiʻekiʻe a i ʻole ka wikiwiki kiʻekiʻe loa a paʻa loa.ʻO kēia ʻano o ka bearing he haʻahaʻa haʻahaʻa, palena kiʻekiʻe ka wikiwiki, maʻalahi ka hana, haʻahaʻa kumu kūʻai, a maʻalahi hoʻi e hoʻokō i ka pololei o ka hana kiʻekiʻe.

ʻO ka slewing apo bearing kekahi ʻano o ka hiki ke kikowaena.Ke hoʻohuli ʻia ʻo 10 degere e pili ana i ka lua hale, e hana mau ana ia, akā aia kekahi hopena i ke ola o ka bearing.Slewing apo hali hīnaʻi i ka hapanui hehi kila papa corrugated hīnaʻi, a nui bearings i ka nui kaʻa-hana metala paʻa hīnaʻi.ʻO ke sila o ka slewing ring bearing ka mea e pale aku ai i ka momona piha mai ka lele ʻana ma kekahi ʻaoʻao, a ma ka ʻaoʻao ʻē aʻe e pale i ka lepo o waho, nā haumia a me ka wai mai ke komo ʻana i loko o ka bearing a pili i ka hana maʻamau.

ʻOiai ʻo ka hapa nui o nā bearings slewing e hana ma lalo o ka haʻahaʻa kaumaha a me ka wikiwiki haʻahaʻa, ʻo ke ʻano sealing o ka bearing e hoʻohana i ʻelua mau hale: rubber seal ring seal a me labyrinth seal.He ʻano maʻalahi ka hoʻopaʻa ʻia ʻana o ke apo seal seal.Ua hoʻohana nui ʻia ma muli o kāna hana liʻiliʻi a me ka hana hoʻopaʻa paʻa pono.Eia nō naʻe, ʻo kona hemahema, ʻo ka lehelehe hoʻopaʻa ʻana i ka lāʻau lapaʻau e maʻalahi i ka wā kahiko i ka wela kiʻekiʻe a nalowale kāna hana sila.No laila, kūpono ke apo slewing e hana ana ma lalo o nā kūlana wela kiʻekiʻe E hoʻohana i ka sila labyrinth.
