Ii-slewing bearngokuyinhloko yakhiwe iringi yangaphandle, iringi yangaphakathi, izakhi ezigoqayo, idivayisi yokuvala kanye nomshini wokugcoba.Kuwumthwalo wokusekela ongathwala umthwalo we-axial, umthwalo we-radial kanye nomthwalo ogumbuqela ngesikhathi esifanayo.Izici ezifana nomthamo oqinile wokuthwala.I-slewing bearing wuhlobo olusha lwengxenye yomshini oluthuthuke kancane kancane ngokuthuthukiswa kwemboni yemishini emhlabeni eminyakeni engama-50 edlule.Kancane kancane iye yanda kusukela kuma-cranes e-tower cranes, ama-cranes wamaloli, kanye ne-excavators kuya emishinini yokuthutha kanye nemishini ye-metallurgical., imishini yokucubungula ukudla, impahla yezempi (amathangi, izibhamu ezilwa nezindiza, i-radar, ama-rocket launch pads), imishini yezokwelapha, izitebhisi, imishini yomoya, amarobhothi, izindawo zokuzijabulisa ezijikelezayo kanye neminye imikhakha.
Ukuthuthukiswa kwei-slewing bearimikhiqizo e-China yaqala sekwephuzile kakhulu, okungukuthi, ayizange ibe nesilinganiso esithile kuze kube sekupheleni kwawo-1970 kanye nasekuqaleni kwawo-1980.Ekuqaleni, ibhola lokuxhumana elinamaphuzu amane eliwumugqa owodwai-slewing bearyayisetshenziswa kakhulu emakethe, futhi ububanzi bomzila womjaho wawuphakathi kuka-Φ500~Φ1500mm, okubala iningi lawo;manje, ngokuthuthukiswa kwemishini yokwakha, izimoto ezikhethekile kanye namarobhothi ezimboni Ngokuthuthukiswa kwemikhiqizo ethwala ama-slewing, kuyilapho isidingo semikhiqizo ethwala ama-slewing sikhula usuku nosuku, izidingo eziphakeme zibekwe phambili zekhwalithi kanye nokusungulwa kwemikhiqizo.
Qhathanisa nokwangaphambilini, manje i-slewing bear inezinhlobo eziningi, Njenge:
- Umugqa owodwa wesakhiwo sebhola lokuxhumana
- Umugqa owodwa we-cross roller isakhiwo
- Imigqa ephindwe kabili yebhola ehlukile kanye nesakhiwo sebhola lemigqa ekabili
- Isakhiwo serowu lamarowu amathathu
- Inhlanganisela ye-Ball & Roller
Futhi manje ukunemba kuphezulu, futhi singakwazi ukugaya amazinyo ukuze sibambe ukunemba ibanga lesi-6.
Okokusebenza okuluhlaza, asigcini nje ngezinto ezivamile ezingu-50MN, 42CRMO, manje singakwazi futhi nge-C45, S48C, noma ibanga lelinye izwe, ngisho nensimbi engagqwali engu-2CR13.
Uma udinga i-anti-corrosion, singenza ukwelashwa okungaphezulu okufana nokudweba, ukwenza i-galvanizing, i-zinc yokufafaza eshisayo, i-nickel plating, njll.
Okwamanje, i-slewing bear yasekhaya ibilokhu ithuthuka ngokuqhubekayo futhi iya emakethe esezingeni eliphezulu.
