Thekuurayainonyanya kuumbwa nemhete yekunze, rin'i yemukati, zvinhu zvinomonereka, mudziyo wekusimbisa uye mudziyo wekuzora.Itsigiro inotakura iyo inogona kutakura axial mutoro, radial mutoro uye kupidigura mutoro panguva imwe chete.Zvimiro zvakadai sekutakura simba rakasimba.Slewing bearing imhando nyowani yemuchina wechikamu uyo ​​wakagadziridzwa zvishoma nezvishoma nekuvandudzwa kweindasitiri yemichina munyika mumakore makumi mashanu apfuura.Iyo yakawedzera zvishoma nezvishoma kubva kune tower cranes, marori cranes, uye ekuchera kusvika kumichina yekufambisa nemichina yesimbi., michina yekugadzira chikafu, midziyo yehondo (matangi, anti-ndege pfuti, radar, rocket launch pads), michina yekurapa, manera, windmill, marobhoti, inotenderera yekuvaraidza nzvimbo uye mimwe minda.

Kubudirira kwekuurayazvigadzirwa muChina zvakatanga kunonoka, ndiko kuti, yakanga isina imwe chiyero kusvika mukupera kwema1970 uye kutanga kwema1980.Pakutanga, imwe-mutsara mana-point yekuonana bhorakuurayandiyo yainyanya kushandiswa pamusika, uye dhayamita remujaho raiva pakati pe Φ500~Φ1500mm, richiverengera vazhinji vavo;ikozvino, nekuvandudzwa kwemichina yekuvaka, mota dzakakosha uye marobhoti eindasitiri Nekuvandudzwa kwezvigadzirwa zvinouraya, nepo kudiwa kwezvigadzirwa zvekuuraya zviri kuwedzera zuva nezuva, zvinodiwa zvepamusoro zvinoiswa pamberi pemhando uye hunyanzvi hwezvigadzirwa.

Enzanisa neyakapfuura, ikozvino kuuraya kune marudzi mazhinji, Se:

1. Mutsara mumwechete mana kusangana bhora chimiro
2. Single row cross roller structure
3. Kaviri mutsara bhora rakasiyana uye Kaviri mutsara bhora chimiro
4. Tatu mutsara roller chimiro
5. Bhora & Roller musanganiswa

Uye iko zvino iko kurongeka kwakakwira, isu tinokwanisawo kugeda-geda mazino kuti tibate giredhi rechitanhatu chairo.

Kune iyo mbishi, isu kwete chete nezvakajairwa zvinhu 50MN, 42CRMO, ikozvino tinogona zvakare neC45, S48C, kana imwe nyika giredhi, kunyange Stainless simbi 2CR13.

Kana iwe uchida anti-corrosion, tinogona kuita kurapa kwepamusoro sekupenda, galvanizing, thermal spraying zinc, nickel plating, nezvimwe.

Parizvino, kutakura kwemumba kwave kuenderera mberi uye kuenda kumusika wepamusoro-soro.
