1. Umonakalo owenzeka ekubulaleni

Kumatshini wolwakhiwo ohlukeneyo onje ngeekhreyini zelori kunye nabembi, umsesane wokuxhela yinxalenye ebalulekileyo ehambisa umthwalo we-axial, umthwalo weradial kunye nomzuzu wokubetha phakathi kwe-turntable kunye ne-chassis.

Kwiimeko zomthwalo okhanyayo, unokusebenza ngokuqhelekileyo kwaye ujikeleze ngokukhululekile.Nangona kunjalo, xa umthwalo unzima, ngokukodwa kwinqanaba eliphezulu lokunyusa kunye noluhlu oluphezulu, kunzima ukuba into enzima ijikeleze, okanye ingakwazi ukujikeleza konke, ukwenzela ukuba ibambelele.Ngeli xesha, iindlela ezinjengokunciphisa uluhlu, ukulungelelanisa abaphumayo, okanye ukuhambisa indawo ye-chassis zihlala zisetyenziselwa ukuthobisa umzimba ukunceda ukuqonda intshukumo ejikelezayo yento enzima kwaye ugqibezele ukuphakamisa okucwangcisiweyo kunye neminye imisebenzi.Ke ngoko, ngexesha lomsebenzi wogcino, kudla ngokufunyaniswa ukuba umdyarho webhere yokuxhela wonakaliswe kakhulu, kwaye iintanda ze-annular ecaleni kwendlela yomdyarho ziveliswa kumacala omabini ogqatso lwangaphakathi kunye nendlela esezantsi yomdyarho phambi kwendawo yokusebenza. indawo, ebangela ukuba umdyarho ongaphezulu wendlela yokubaleka uxinezeleke kwindawo enoxinzelelo kakhulu., kwaye uvelise iintanda ze-radial kulo lonke ukudandatheka.

2. Ingxoxo ngezizathu zomonakalo kwiibheringi zokuxhela

(1) Impembelelo yento yokhuseleko Ukubethelwa kwe-slewing ngokuqhelekileyo kuqhutywe phantsi kweemeko zesantya esiphantsi kunye nomthwalo onzima, kwaye umthamo wayo wokuthwala unokubonakaliswa ngokubanzi ngomthamo we-static, kwaye ukulinganisa umthamo we-static urekhodwa njenge-C0 a.Into ebizwa ngokuba yi-static capacity ibhekisela kumandla okuthwala i-slewing bear xa ukuguqulwa kwesigxina somdyarho δ kufikelela kwi-3d0/10000, kwaye i-d0 yi-diameter ye-rolling element.Ukudibanisa imithwalo yangaphandle ngokuqhelekileyo imelwe ngumthwalo olinganayo we-Cd.Umlinganiselo womthamo omileyo kumthwalo olinganayo ubizwa ngokuba yinto yokhuseleko, echazwe njenge-fs, eyona siseko esisisiseko soyilo kunye nokukhethwa kweebheringi zokubulala.

Xa indlela yokukhangela uxinzelelo oluphezulu loqhagamshelwano phakathi kwe-roller kunye ne-raceway isetyenziselwa ukuyila ukubethelwa kwe-slewing, uxinzelelo loqhagamshelwano lomgca [σk line] = 2.0 ~ 2.5 × 102 kN / cm isetyenziswa.Okwangoku, abaninzi abavelisi bakhetha kwaye babale uhlobo lwe-slewing bearing ngokobukhulu bomthwalo wangaphandle.Ngokutsho kolwazi olukhoyo, uxinzelelo loqhagamshelwano lwe-slewing bear ye-crane encinci ye-tonnage incinci kune-crane enkulu ye-tonnage okwangoku, kwaye eyona nto yokhuseleko iphezulu.Inkulu i-tonnage ye-crane, ubukhulu be-diameter ye-slewing bear, i-ezantsi i-product yachaneka, kwaye iyancipha into yokhuseleko.Esi sizathu esisisiseko sokuba kutheni ukubethelwa kwe-crane ye-tonnage enkulu kulula ukonakalisa kune-slewing bear ye-crane encinci ye-tonnage.Okwangoku, ngokuqhelekileyo kukholelwa ukuba uxinzelelo loqhagamshelwano lomgca we-slewing bear ye-crane ngaphezu kwe-40 t akufanele idlule i-2.0 × 102 kN / cm, kwaye into yokukhusela akufanele ibe ngaphantsi kwe-1.10.

(2) Impembelelo yokuqina kwesakhiwo se-turntable

Umsesane wokubethelwa yinxalenye ebalulekileyo ehambisa imithwalo eyahlukeneyo phakathi kwe-turntable kunye ne-chassis.Ukuqina kwayo akukukhulu, kwaye ubukhulu becala kuxhomekeke kubulukhuni besakhiwo se-chassis kunye ne-turntable eyixhasayo.Ukuthetha ngethiyori, isakhiwo esifanelekileyo se-turntable yi-cylindrical shape ene-rigidity ephezulu, ukwenzela ukuba umthwalo kwi-turntable unokwabiwa ngokulinganayo, kodwa akunakwenzeka ukufezekisa ngenxa yokuphakama komda womatshini wonke.Iziphumo zohlalutyo lwezinto ezinqamlekileyo ze-turntable zibonisa ukuba ukuguqulwa kwepleyiti esezantsi edityaniswe kwi-turntable kunye ne-slewing bear inkulu, kwaye inzulu ngakumbi phantsi kwemeko yomthwalo omkhulu, obangela ukuba umthwalo ugxininise. inxalenye encinci ye-roller, ngaloo ndlela ukwandisa umthwalo we-roller enye.Uxinzelelo olufunyenweyo;ingakumbi enzulu kukuba deformation yesakhiwo turntable iya kutshintsha imeko yoqhagamshelwano phakathi roller kunye nomdyarho, ukunciphisa kakhulu ubude zoqhagamshelwano kwaye kubangele ukwanda okukhulu kuxinzelelo loqhagamshelwano.Nangona kunjalo, iindlela zokubala zokuxinzezeleka koqhagamshelwano kunye nomthamo we-static osetyenziswa ngokubanzi ngoku zisekelwe kwisiseko sokuba ukubethelwa kwe-slewing kugxininiswe ngokulinganayo kunye nobude boqhagamshelwano obusebenzayo be-roller yi-80% yobude be-roller.Ngokucacileyo, lo mgaqo awuhambelani neyona meko.Esi sesinye isizathu sokuba i-slewing ring kulula ukuyonakalisa.

(3) Impembelelo yemeko yonyango lokushisa

Umgangatho wokucubungula we-slewing bear ngokwayo uchaphazeleka kakhulu kukuchaneka kokuvelisa, ukukhutshwa kwe-axial kunye nombuso wokushisa ukushisa.Into enokuhoywa ngokulula apha yimpembelelo yesimo sonyango lobushushu.Ngokucacileyo, ukuze kuthintelwe iintanda kunye nokudakumba kumphezulu wendlela yomdyarho, kuyafuneka ukuba umphezulu wendlela yomdyarho ube nobunzulu obaneleyo bomaleko oqinileyo kunye nobunzima obungundoqo ukongezelela kubulukhuni obaneleyo.Ngokutsho kwedatha yangaphandle, ubunzulu bomgangatho oqinileyo wendlela yomdyarho kufuneka buqiniswe ngokunyuka komzimba oqengqelekayo, ubunzulu bunokugqithisa i-6mm, kwaye ubulukhuni beziko kufuneka bube phezulu, ukuze ugqatso lube nesantya esiphezulu. ukuxhathisa.Ngoko ke, ubunzulu boluhlu oluqinisiweyo phezu komgca we-slewing bearing raceway awanelanga, kwaye ubunzima be-core buphantsi, okuyenye yezizathu zokulimala kwayo.

3.Amanyathelo okuphucula

(1) Ngokuhlalutya okulinganiselweyo, ukwandisa ngokufanelekileyo ubukhulu beplate yecandelo lokudibanisa phakathi kwe-turntable kunye ne-slewing bear, ukwenzela ukuba kuphuculwe ubulukhuni besakhiwo se-turntable.

(2) Xa uyila iibheringi zokubethelwa kobubanzi obukhulu, into yokhuseleko kufuneka yandiswe ngokufanelekileyo;ngokufanelekileyo ukwandisa inani rollers nako ukuphucula imeko yoqhagamshelwano phakathi rollers kunye nomdyarho.

(3) Ukuphucula ukuchaneka kokuveliswa kwe-slewing bear, kugxininise kwinkqubo yokunyanga ukushisa.Inokunciphisa isantya esiphakathi sokucima isantya, izame ukufumana ubunzima obukhulu bomhlaba kunye nobunzulu bokuqina, kwaye ithintele ukucima iintanda kumphezulu wendlela yomdyarho.
