I-Gearbox bearing: anti-friction ekudluliseni

I-gearbox ephethe (ibhokisi legiya) - ingxenye yebhokisi lemishini yezimoto;i-rolling bearing ye-design eyodwa noma enye, esebenza njengezisekelo zamashafu namagiya we-gearbox.

Ngokuya ngohlobo lwayo, inani lamagiya, indlela yokudlulisa i-torque phakathi kwezinto kanye nomklamo, kusuka ku-4 kuya ku-12 noma ngaphezulu ama-bearings ezinhlobo ezahlukene angasetshenziswa ku-gearbox.Amabhere axazulula izinkinga eziningana:

● Ukwenza imisebenzi yokusekela yawo wonke amashafu angawodwana noma kuphela (ezimweni eziningi - izisekelo ezimbili zawo wonke ama-shaft, kwamanye amabhokisi izikimu ezilula noma eziyinkimbinkimbi - usekelo olulodwa lwe-shaft yokufaka, izisekelo ezintathu ze-shaft yesibili, njll.) ;
● Isebenza njengesekela lamagiya afakwe ku-shaft yesibili (kuma-gearbox anamagiya avumelanisiwe namagiya ajikelezayo mahhala ku-shaft yesibili);
● Ukunciphisa amandla okungqubuzana ku-shaft kanye nezisekelo zegiya (ukunciphisa ukulahlekelwa kwetorque ekudluliseni, ukunciphisa ukushisisa kwezingxenye zayo).

Ukusetshenziswa kwama-bearings kuqinisekisa ukufakwa okulungile kwezingxenye ezihambayo ze-gearbox futhi kunciphisa kakhulu amandla okungqubuzana avela phakathi kwalezi zingxenye.Isimo nezici zama-bearings zinquma ukusebenza kwe-gearbox, ikhono layo lokudlulisa nokushintsha i-torque, futhi ngokuvamile liqinisekisa ukulawuleka kwemoto.Ngakho-ke, ama-bearings agugile futhi angenasici kufanele ashintshwe, futhi ukuze ukhethe kahle lezi zingxenye, kuyadingeka ukuqonda ukuklama kwazo, izinhlobo nokusetshenziswa kwazo.

Izinhlobo, ukwakheka kanye nezici zama-gearbox bearings

Emotweni, ugandaganda namanye ama-gearbox okuthutha, kusetshenziswa ama-bearings ajwayelekile ezinhlobo ezimbalwa eziyinhloko:

● Amabhola anomugqa owodwa we-radial kanye nama-angular contact;
● Ibhola elinemigqa emibili yokuxhumana kwe-angular;
● Amarola angama-radial anomugqa owodwa;
● I-roller eyindilinga yomugqa owodwa;
● Inaliti yerola yomugqa owodwa kanye nomugqa okabili.

Ngayinye yezinhlobo zama-bearings inezici zayo kanye nokusebenza kwayo kuma-gearbox.

Amabhola eradial anomugqa owodwa.Ama-bearings ajwayeleke kakhulu angasetshenziswa njengezisekelo zawo wonke ama-gearbox shafts.Ngokwesakhiwo, iqukethe amasongo amabili, phakathi kwawo kukhona umugqa wamabhola ensimbi kusihlukanisi.Ngezinye izikhathi amabhola embozwe ngensimbi noma epulasitiki izindandatho ukuvimbela ukulahlekelwa lubrication.Ama-Bearing alolu hlobo asebenza kahle kakhulu emabhokisini alayishwe kancane ezimoto nezithuthuthu, kodwa ngezinye izikhathi ayatholakala nakweminye imishayo yamabhokisi ezimpahla.

Amabhola okuxhumana angumugqa owodwa.Lawa ma-bearings ngokuvamile abona imithwalo ye-radial kanye ne-axial, avame ukusetshenziswa njengezisekelo zangemuva ze-shafts eyinhloko neyesibili, okuthi ngesikhathi sokusebenza kwebhokisi le-gearbox ingakwazi ukuthwala imithwalo eqondiswe eduze kwe-axis (ngenxa yokuhamba kwama-synchronizers nokugcizelela kwawo. emagiyeni).Ngokwesakhiwo, i-angular contact beararing ifana ne-radial bear, kodwa izindandatho zayo zinezitobhi ezivimbela isakhiwo ukuthi singawi ngaphansi kwemithwalo ye-axial.

Ibhola le-angular thrust enemigqa ekabili.Ama-Bearings alolu hlobo aphikisana kakhulu nemithwalo ephezulu, ngakho-ke ngokuvamile asetshenziselwa ukusekelwa kwangemuva kwe-shaft eyinhloko futhi ngezinye izikhathi ephakathi.Ngokuklama, ama-bearings anjalo afana ne-single-row bearings, kodwa asebenzisa amasongo abanzi anezitobhi zangaphandle zamabhola.

I-roller yomugqa owodwa.Lawa ma-bearings angasebenza ngaphansi kwemithwalo ephakeme kunama-ball bearings, ngakho asetshenziswa njengezisekelo zawo wonke ama-shafts ku-gearbox yemishini yezimoto - amaloli, ogandaganda, imishini ekhethekile, imishini yezolimo, njll. Ngokwesakhiwo, ama-bearings alolu hlobo afana nama-ball bearings. , kodwa basebenzisa ama-roller njengezakhi ezigoqayo - amasilinda amafushane, kanye nekheji, ahlanganiswe phakathi kwamasongo anezindawo zangaphakathi eziyisicaba.

Irowu eliyikhoyili eliwumugqa owodwa kanye nomugqa okabili.Ama-Bearings alolu hlobo ngokuvamile abona kokubili imithwalo ye-radial ne-axial, kuyilapho ekwazi ukumelana nemithwalo ephezulu kunamabhola.Ama-bearings anjalo asetshenziswa kakhulu njengezisekelo zangemuva nangaphambili zawo wonke ama-shafts, ama-double-tapered bearings asetshenziswa ezisekelweni zangemuva zama-shafts ayisisekelo kanye nesesibili.Idizayini yalokhu kuthwala isebenzisa ama-roller ane-tapered, afakwe phakathi kwamasongo amabili anezindawo zangaphakathi ezi-beveled.

Inaliti yerola yomugqa owodwa kanye nomugqa okabili.Ama-Bearings alolu hlobo, ngenxa yokuklama kwawo, anezilinganiso ezincane ezinokumelana okuphezulu kwemithwalo ye-radial - lokhu kutholakala ngokusebenzisa ama-roller-diameter amancane (izinaliti) njengemizimba yokujikeleza, futhi ngezinye izikhathi ngaphezu kwalokho ngokushiya izindandatho kanye / noma amakheji.Imvamisa, amabhodi enaliti asetshenziswa njengezisekelo zegiya ku-shaft yesibili, njengokwesekwa kwe-shaft yesibili (lapho uzwane lwayo lukhona ekugcineni kwe-shaft yokufaka), kancane kancane njengoba i-countershaft isekela.
