I-Angular Contact Ball Bearing

Umugqa owodwa wamabhola angama-angular contact
Umugqa owodwa wamabhola angama-angular ahlanganisa iringi yangaphandle, iringi yangaphakathi, umugqa wamabhola ensimbi kanye nekheji. Lolu hlobo lokuthwala lungathwala umthwalo we-radial kanye nomthwalo we-axial ngesikhathi esifanayo, futhi lungathwala umthwalo ohlanzekile we-axial, futhi lungasebenza ngesivinini esikhulu. Umugqa owodwa wamabhola angama-angular angakwazi ukumelana nemithwalo ye-axial ohlangothini olulodwa. Uma ingaphansi kwemithwalo ye-radial, amandla e-axial engeziwe azongeniswa, futhi ukuxoshwa kwe-axial ye-shaft nezindlu kunganqunywa kuphela ohlangothini olulodwa. Nakuba lolu hlobo lokuthwala lungathwala kuphela imithwalo ye-axial ohlangothini olulodwa, lungahlanganiswa nolunye uhlobo oluthwala imithwalo ngakolunye uhlangothi. Uma ifakwe ngababili, ubuso obufanayo bokuphela kwezindandatho zangaphandle ze-pair of bearings zibhekene nomunye nomunye, ukuphela okubanzi kubheke ububanzi.
kanye nobuso (i-back-to-back DB), kanti isiphetho esincane sibhekene nobuso obuncane bokugcina (i-DF yobuso nobuso), ukuze ugweme ukubangela amandla e-axial engeziwe, Futhi, i-shaft noma indlu ingakhawulelwa ekudlaleni kwe-axial kuzo zombili izinkomba.

I-angular yebhola yokuxhumana enomugqa owodwa inamabhola amaningi kune-deep groove ibhola enosayizi ofanayo, ngakho-ke umthwalo olinganiselwe mkhulu kunawo wonke ekuphatheni ibhola, ukuqina nakho kunamandla, futhi ukusebenza kuzinzile. Ukukhishwa kwe-radial kungalungiswa ngokugudluka okuhlangene kwamasongo angaphakathi nangaphandle, futhi amasethi amaningana ama-bearings angaxhunywa ngokuhambisana ukuze kubangele ukuphazamiseka kwangaphambili ukuze kuthuthukiswe ukuqina kwesistimu.
Ukusetshenziswa kwama-angular ball bearings akukwazi ukuhlakazwa, futhi ikhono layo lokuziqondanisa lilinganiselwe kakhulu.
Isici salolu hlobo lokuthwala ukuthi i-engeli yokuxhumana ayiyona i-zero, futhi ama-engeli okuxhumana ajwayelekile omugqa owodwa wama-angular amabhola okuxhumana angu-15 °, 25 °, 30 °, no-40 °. Usayizi we-engeli yokuxhumana unquma amandla e-radial namandla e-axial i-axial engakwazi ukumelana nayo ngesikhathi sokusebenza. Uma i-engeli yokuxhumana inkulu, umthamo omkhulu womthwalo we-axial engamelana nawo. Kodwa-ke, i-engeli yokuxhumana incane, iba ngcono kakhulu ekujikelezeni kwesivinini esikhulu.
Amabhola angama-angular axhumene nomugqa owodwa awanakho imvume engokwemvelo. Amabhola okuxhumana angular ahlangene kuphela anemvume yangaphakathi. Ngokwezidingo zezimo zokusebenza, kunezindlela ezimbili zokuhlinzeka ngama-bearings ahlanganisiwe: ukulayisha kuqala (preload) kanye ne-preclearance (imvume esethiwe). Ukucaciswa kwangaphakathi kwama-angular amabhola okuxhumana alayishwe ngaphambili kunguziro noma kunegethivu. Ivamise ukusetshenziswa ku-spindle yamathuluzi omshini ukuze kuthuthukiswe ukuqina nokunemba kokujikeleza kwe-spindle. Ukucaciswa (ukulayisha kuqala) kwamabheringi amabhola okuxhumana angular abhanqiwe kulungisiwe ngaphambi kokuphuma embonini, futhi akukho ukulungisa komsebenzisi okudingekayo. Ukubekezelelana kobubanzi okuyinhloko kanye nokuphuma kobuso bokuphela kwama-bearings amabhola okuxhumana angama-angular avamile akhiqizwa kuphela ngokwamamaki ajwayelekile, futhi awakwazi ukubhangqwa futhi ahlanganiswe ngokuthanda kwakhe.
Ukukhiqizwa kwama-angular amabhola okuxhumana ahlangene angahlanganiswa nganoma iyiphi indlela, njenge-back-to-back, ubuso nobuso noma uchungechunge. Kunezindlela ezimbili zokuhlinzeka ngama-bearings afanayo wendawo yonke: ukulayisha kuqala (ukulayisha kuqala) kanye ne-preclearance (imvume esethiwe). Ngaphandle kokuhlanganiswa kwendawo yonke, ama-bearings ngamanye kwamanye ama-bearings ahlanganisiwe awashintsheki.
Amabhola angama-angular oxhumene nawo amarowu amabili
Idizayini yemigqa ephindwe kabili yamabhole angama-angular athintana nawo ngokuyisisekelo iyafana naleyo yamabheringi angama-angular othintana nawo womugqa owodwa, kodwa ithatha kuphela isikhala esincane se-axial. Amarowu amabili ama-angular amabhola okuxhumana angamelana nemithwalo ye-radial kanye nemithwalo ye-axial esebenza kuzo zombili izinkomba. Amalungiselelo okuthwala okuqinile okuphezulu ayatholakala futhi angamelana nezikhathi zokugingqika.
Umugqa owodwa wamabhola angama-angular othintana nawo kanye namabheringi amabhola ahlangene angama-angular
Ukuze kuthuthukiswe ukuqina kanye namandla okuthwala umthwalo wama-angular contact ball bearings, ama-angular amabhola okuxhumana okucaciswe okufanayo avame ukuqoqwa ngama-double quadruple (QBCQFC, QT) noma i-quintuple (PBC, PFC, PT, PBT, PFT) amafomu. Kumabhorelo amabhola okuxhumana angama-angular kabili, izindlela zokuhlela zihlukaniswe zaba izinhlobo ezintathu: i-back-to-back (DB), ubuso nobuso (DF), kanye ne-tandem (DT). Ama-back-to-back angular amabhola okuxhumana afanele ukuthwala imithwalo ye-radial ehlukene noma ehlanganisiwe ne-axial, futhi angakwazi ukumelana nemithwalo ye-axial ye-bidirectional. Ingakwazi ukubekezelela umzuzu omkhulu wokugumbuqela futhi inokuqina okuqinile. Ukulayisha kuqala okuhlukile kungasetshenziswa ngokuya ngezimo zokusebenza. Ama-angular contact ball bearings angaphansi kwezikhathi ezimbalwa zokugingqika futhi anikeze ukuqina kwesistimu okuphansi. Inzuzo yukuthi ayizweli kakhulu ekuthwaleni amaphutha e-concentricity yezindlu. Ama-angular ball bearings ahlelwe ngochungechunge avunyelwe kuphela ukuthwala umthwalo omkhulu we-axial ohlangothini olulodwa. Ezimweni eziningi, intwasahlobo isetshenziselwa ukufaka ukulayisha kuqala, futhi inani lomthwalo we-radial elingasekelwa kanye nokuqina kwe-bearing kuncike kunani lokulayisha kuqala elikhethiwe.
