Ama-bearings ebhola lokuxhumana elinomugqa owodwa kanye nelinomugqa ophindwe kabili

Ama-bearings ebhola lokuxhumana eliyi-angularzakhiwe ngendandatho yangaphandle, indandatho yangaphakathi, ibhola lensimbi, kanye nekheji. Ingathwala imithwalo ye-radial kanye ne-axial, futhi ingathwala imithwalo ye-axial emsulwa, futhi ingasebenza ngokuzinzile ngesivinini esiphezulu. Ama-bearings ebhola lokuxhumana elingumugqa owodwa angamelana nemithwalo ye-axial ohlangothini olulodwa. Uma lolu hlobo lokuthwala luthwala umthwalo we-radial omsulwa, ngoba umugqa womthwalo we-rolling element kanye nomugqa womthwalo we-radial azikho endizeni efanayo ye-radial, ingxenye ye-axial yangaphakathi iyakhiqizwa, ngakho-ke kumele ifakwe ngamabili.

 

1. Ama-bearings ebhola lokuxhumana elingumugqa owodwa

Ama-bearings ebhola lokuxhumana elingumugqa owodwa anezinhlobo ezilandelayo zesakhiwo:

(1) Ama-bearings ebhola lokuxhumana eliyi-angular ahlukaniswayo

Uhlangothi lwangaphandle lomjaho walolu hlobo lwebhereyi alunawo umgodi wokukhiya, ongahlukaniswa nendandatho yangaphakathi, ikheji kanye nenhlangano yebhola, ukuze lufakwe ngokwehlukana. Lolu hlobo lwamabhereyi amancane anobubanzi bangaphakathi obungaphansi kuka-10mm asetshenziswa kakhulu kuma-rotor e-gyrocopic, ama-micromotor nakwamanye amadivayisi anezidingo eziphezulu zokulinganisela okuguquguqukayo, umsindo, ukudlidliza kanye nokuzinza.

 

(2) Ama-bearings ebhola lokuxhumana elingahlukaniseki

Umsele wendandatho walolu hlobo lwebhereyi unesikhala sokukhiya, ngakho-ke amasongo amabili awakwazi ukuhlukaniswa. Kunezinhlobo ezintathu ngokwe-engeli yokuxhumana:

(1) I-engeli yokuxhumana α=40°, efanelekile ukuthwala umthwalo omkhulu we-axial;

(2) I-engeli yokuxhumana engu-α=25°, esetshenziswa kakhulu kuma-bearings e-spindle anembile;

(3) I-engeli yokuxhumana α=15°, esetshenziswa kakhulu kuma-bearings amakhulu anokunemba.

(3) Ama-bearings ebhola lokuxhumana eliyi-angular ahlelwe ngamabili

 

Ama-bearings ebhola lokuxhumana eliyi-angularIhlelwe ngamabili isetshenziselwa ukwamukela imithwalo ye-radial neye-axial, kanye nemithwalo ye-radial emsulwa kanye nemithwalo ye-axial kunoma iyiphi indlela. Lolu hlobo lwe-bearing lukhethwa futhi luhlanganiswe ngamabili ngumenzi ngokwezidingo ezithile zokulayisha kusengaphambili, futhi lunikezwa abasebenzisi. Lapho i-bearing ifakwa emshinini futhi iqinisiwe, indawo evulekile ku-bearing isuswa ngokuphelele, futhi indandatho nebhola zisesimweni sokulayisha kusengaphambili, ngaleyo ndlela kuthuthukiswe ukuqina kwe-bearing ehlanganisiwe.

 

Ama-bearings ebhola lokuxhumana eliyi-angular ahlelwe ngamabili atholakala ngezindlela ezintathu ezahlukene:

(1) Ukucushwa okulandelanayo, i-post-code DB, lokhu kucushwa kunokuqina okuhle, ukusebenza okuhle kokumelana nesikhathi sokugumbuqela, futhi ibhere lingathwala umthwalo we-axial onezindlela ezimbili;

 

(2) Ukucushwa kobuso nobuso, ikhodi yangemuva yi-DF, ukuqina kwalokhu kucushwa kanye nekhono lokubekezelela isikhathi sokugumbuqela akukuhle njengefomu lokucushwa kwe-DB, futhi ibhere lingathwala umthwalo we-axial onezindlela ezimbili;

 

(3) Ukuhlelwa kwe-tandem, i-post-code DT, lokhu kulungiselelwa kungaxhunywa ngochungechunge ngama-bearings amathathu noma ngaphezulu ekusekelweni okufanayo, kodwa kungathwala umthwalo we-axial kuphela ohlangothini olulodwa. Ngokuvamile, ukuze kulinganiswe futhi kuncishiswe ukufuduka kwe-axial kwe-shaft, kufakwa i-bearing ekwazi ukuthwala umthwalo we-axial kolunye uhlangothi kolunye uhlangothi.

 

2. Ama-bearings ebhola lokuxhumana eliyimigqa emibili

Ama-bearings ebhola lokuxhumana eliyimigqa emibili abonakala ngekhono lokubekezelela umthwalo ohlangene wemithwalo ye-radial kanye ne-axial ngasikhathi sinye, okunciphisa ukuhamba kwe-axial kwezinhlangothi zombili zomgodi.

Uma kuqhathaniswa ne-thrust ball bearing enezindlela ezimbili, lolu hlobo lwe-bearing lunesivinini esiphezulu kakhulu, i-engeli yokuxhumana engu-32°, ukuqina okuhle, futhi lungamelana nesikhathi esikhulu sokujika, futhi lusetshenziswa kabanzi endaweni yesondo langaphambili lemoto (amanye amamodeli asebenzisa nama-roller bearing anemigqa emibili enobukhulu obufanayo).

 

Kunezinhlobo ezine zesakhiwo sama-bearings ebhola lokuxhumana eliyimigqa emibili:

(1) Umklamo ojwayelekile wama-bearings ohlobo A anobubanzi bangaphandle obungaphansi noma obulingana no-90mm. Akukho notch yebhola, ngakho-ke ingamelana nemithwalo ye-axial elinganayo kuzo zombili izinhlangothi. Ikheji le-nylon 66 eliqiniswe ngefayibha yengilazi elula liyasetshenziswa, futhi ukuphakama kwezinga lokushisa kwe-bearings kuncane kakhulu.

(2) Umklamo ojwayelekile wama-bearings ohlobo A anobubanzi bangaphandle obungaphezu kuka-90mm. Kukhona indawo yokulayisha ohlangothini olulodwa futhi ifakwe ikheji eligxivizwe ngepuleti lensimbi noma ikheji eliqinile lethusi.

(3) Uhlobo E luyisakhiwo esiqinisiwe, esinomugqa webhola ohlangothini olulodwa, esingabamba amabhola ensimbi amaningi, ngakho-ke amandla okuthwala aphezulu.

 

(4) Ama-bearings ebhola lokuxhumana eliyimigqa emibili anesivalo sothuli kuzo zombili izinhlangothi kanye nomklamo wohlobo lwendandatho yokuvala u-A nohlobo lwe-E angafakelwa isivalo sothuli (uhlobo olungeyona eyokuxhumana) noma indandatho yokuvala uthuli (uhlobo lokuxhumana) kuzo zombili izinhlangothi. Ingaphakathi lama-bearings avaliwe ligcwele i-anti-rust lithium grease, futhi izinga lokushisa lokusebenza ngokuvamile lingu-30~+110°C. Akukho ukuphinda kufakwe uketshezi ngesikhathi sokusetshenziswa, futhi akufanele kufudunyezwe noma kuhlanzwe ngaphambi kokufakwa.

 

Uma ufaka ama-bearings ebhola lokuxhumana eliyimigqa emibili, kufanele kuqashelwe ukuthi nakuba i-bearing ingamelana nemithwalo ye-axial ejikelezayo, uma kukhona i-ball notch ohlangothini olulodwa, kufanele kuqashelwe ukuthi umthwalo we-axial oyinhloko ungadluli emseleni ohlangothini olune-notch.
