Ukuthembeka kwesistimu ye-Bearing kuhlale kuyisihloko esishisayo emikhiqizweni yezimoto zikagesi. Sikhulume kakhulu ezihlokweni ezedlule, njengokuthwala izinkinga zomsindo, izinkinga zamanje ze-shaft, ukuthwala izinkinga zokushisisa nokunye. Ukugxila kwalesi sihloko ukucaciswa kwe-motor bear, okungukuthi, ngaphansi kwasiphi isimo sokugunyazwa ukuthwala kusebenza ngokunengqondo.
Ukuze i-bearing isebenze kahle, ukucaciswa kwe-radial kubaluleke kakhulu. Izimiso ezijwayelekile zokulawula nokuba namandla: Ukuvunyelwa kokusebenza kwamabheringi ebhola kufanele kube uziro, noma kube nokulayishwa kuqala kancane. Kodwa-ke, kuma-bearings anjengama-cylindrical rollers nama-spherical rollers, inani elithile lemvume esele kufanele lishiywe ngesikhathi sokusebenza, ngisho noma liyimvume encane.
Ngokuya ngesicelo, imvume yokusebenza enhle noma engalungile iyadingeka ohlelweni lokuthwala. Ezimweni eziningi, imvume yokusebenza kufanele ibe yinani elihle, okungukuthi, lapho ukuthwala kusebenza, kukhona imvume ethile esele. Ngakolunye uhlangothi, kunezinhlelo zokusebenza eziningi ezidinga imvume yokusebenza engemihle - okungukuthi ukulayisha kuqala.
Ukulayisha kuqala ngokuvamile kulungiswa ngesikhathi sokufakwa kumazinga okushisa asendaweni (okungukuthi, kuqedwa ngesikhathi sokuklama nezigaba zokukhiqiza zenjini). Uma ukuphakama kwezinga lokushisa kwe-shaft kukhulu kunesihlalo esithwalayo ngesikhathi sokusebenza, ukulayisha kuqala kuzokwanda.
Lapho i-shaft ishisa futhi inwetshwa, ububanzi be-shaft buzokhula futhi buzonwebeka. Ngaphansi kwethonya lokunwetshwa kwe-radial, ukucaciswa kwe-radial kokuthwala kuzokwehla, okungukuthi, ukulayisha kuqala kuzokwanda. Ngaphansi komthelela wokunwetshwa kwe-axial, ukulayisha kuqala kuzophinde kwandiswe, kodwa ukulayishwa kuqala kokuhlelwa kokuthwala okubuyela emuva kuzoncishiswa. Kuhlelo lwe-back-to-back bearing, uma kunebanga elinikeziwe phakathi kwama-bearings nama-bearings kanye nezingxenye ezihlobene zine-coefficient efanayo yokunwetshwa kwe-thermal, imiphumela yokunwetshwa kwe-radial kanye nokwandiswa kwe-axial ekulayisheni kuqala kuzokhansela ngaphandle, ngakho-ke. ukulayisha kuqala ngeke kwenzeke Okunhlobonhlobo.
Imisebenzi ebaluleke kakhulu yokuthwala ukulayisha kuqala ihlanganisa: ukuthuthukisa ukuqina, ukunciphisa umsindo, ukuthuthukisa ukunemba kwesiqondiso se-shaft, ukunxephezela ukugqoka ngesikhathi sokusebenza, ukwandisa isikhathi sokusebenza, nokuthuthukisa ukuqina. Ukuqina kwe-bearing isilinganiso samandla asebenza ku-bearing nokuguga kwayo okunwebeka. Ukuguqulwa kwe-elastic okubangelwa umthwalo ongaphakathi kobubanzi obuthile bokuthwala okulayishwe ngaphambili kuncane kunaleyo yokuthwala ngaphandle kokulayisha kuqala.
Ukuvunyelwa kokusebenza kokuthwala kuncane, kungcono ukuqondiswa kwezinto ezigoqayo endaweni engalayishiwe futhi kwehlisa umsindo we-bearing ngesikhathi sokusebenza.Ngaphansi komphumela wokulayisha kuqala, ukuchezuka kwe-shaft ngenxa yamandla kuncishiswe, ngakho-ke ukunemba kwesiqondiso se-shaft kungathuthukiswa. Isibonelo, ama-pinion gear bearings namagiya ahlukene angalayishwa ngaphambili ukuze kuthuthukiswe ukuqina nokunemba kokuqondiswa kwe-shaft, okwenza ukuxhuma kwamagiya kucace kakhudlwana futhi kuzinze, futhi kuncishiswe amandla ashukumisayo engeziwe. Ngakho kuzoba nomsindo omncane ngesikhathi sokusebenza, futhi amagiya angaba nempilo ende yokusebenza. Ama-Bearings azokwandisa imvume ngenxa yokugqoka ngesikhathi sokusebenza, okunganxeshezelwa ngokulayishwa kuqala. Kwezinye izinhlelo zokusebenza, ukulayishwa kuqala kohlelo lokuthwala kungathuthukisa ukuthembeka kokusebenza futhi kunwebe impilo yesevisi. Ukulayisha kuqala okufanelekile kungenza ukusatshalaliswa komthwalo ekuthwaleni kulingane, ngakho kungaba nempilo ende yokusebenza.
Lapho kunqunywa ukulayisha kuqala ngohlelo lokuthwala, kufanele kuqashelwe ukuthi uma ukulayisha kuqala kudlula inani elithile elimisiwe eliphezulu, ukuqina kungakhushulwa kuphela ngezinga elilinganiselwe. Ngenxa yokuthi ukungqubuzana nokushisa okubangelwayo kuzokwanda, uma kukhona umthwalo owengeziwe futhi usebenza isikhathi eside, impilo yokusebenza yokuthwala izoncishiswa kakhulu.
Ngaphezu kwalokho, lapho ulungisa ukulayisha kuqala ohlelweni lokuthwala, kungakhathaliseki ukuthi inani lokulayisha kuqala linqunywa ukubala noma isipiliyoni, ukuchezuka kwakho kufanele kulawulwe ngaphakathi kwebanga elithile. Isibonelo, enqubweni yokulungisa ama-roller bearings, ukuthwala kufanele kujikelezwe izikhathi eziningana ukuze kuqinisekiswe ukuthi ama-rollers awakhohliwe, futhi ubuso bokugcina be-rollers kufanele buthintane kahle nezimbambo zendandatho yangaphakathi. Uma kungenjalo, imiphumela etholwe ekuhlolweni noma ekulinganisweni ayilona iqiniso, ukuze ukulayisha kuqala kwangempela kube kuncane kakhulu kunalokho okudingekayo.
