Kuhlelo lokuthwala izinjini, ungakhetha kanjani futhi ufanise ne-fixed end bearing?

Ukuze kukhethwe isiphetho esinqunyiwe sokusekela okuthwala i-motor (okubizwa ngokuthi okuhleliwe), izici ezilandelayo kufanele zicatshangelwe: (1) Izidingo zokulawula ukunemba kwempahla eshayelwa;(2) Uhlobo lomthwalo wemoto;(3) Inhlanganisela ye-axial noma i-bearing kumele ikwazi ukumelana namandla athile e-axial.Ukuhlanganisa izinto zokuklama zalezi zici ezintathu ezingenhla, kumamotho amancane naphakathi nendawo, ama-deep groove ball bearings avame ukusetshenziswa njengenketho yokuqala yama-motor fixed end bearings.

Ama-deep groove ball bearings yiwona asetshenziswa kakhulu ama-rolling bearings.Uma usebenzisa ama-deep groove ball bearings, ukwakheka kwesistimu yokusekela ene-motor ilula kakhulu, futhi nokugcinwa kulula.Ama-deep groove ball bearings ikakhulukazi asetshenziselwa ukuthwala imithwalo ye-radial, kodwa lapho ukucaciswa kwe-radial of the bearings kwanda, anezici zama-angular amabhola okuxhumana futhi angathwala imithwalo ehlanganisiwe ye-radial ne-axial;amabhola ama-thrust awafanele isivinini esikhulu Uma esetshenziswa njenge-axial, angasetshenziswa futhi ukuthwala umthwalo we-axial omsulwa.Uma kuqhathaniswa nezinye izinhlobo zamabhere anezincazelo ezifanayo kanye nobukhulu obufana namabhereni amabhola e-groove ajulile, lolu hlobo lokuthwala lunezinzuzo ze-coefficient encane ye-friction kanye nesivinini somkhawulo ophezulu, kodwa okubi ukuthi akumelani nomthelela futhi akufanelekanga imithwalo esindayo.

Ngemuva kokuthi i-deep groove ball bearing ifakwe ku-shaft, ngaphakathi kobubanzi be-axial clearance ye-bearing, ukulingana kwe-radial ye-shaft noma izindlu kuzo zombili izinkomba kunganqunywa.Esiqondisweni se-radial, i-bearing kanye ne-shaft zisebenzisa ukulingana kokuphazamiseka, futhi i-bearing and the end cover bear chamber noma igobolondo zisebenzisa ukulingana okuncane kokuphazamiseka.Umgomo oyinhloko wokukhetha lokhu kufanelana ukuqinisekisa ukuthi imvume yokusebenza ye-bearing ingu-zero noma kancane ngesikhathi sokusebenza kwemoto.I-Negative, ngakho-ke ukusebenza kokusebenza kwe-bearing kungcono.Esiqondisweni se-axial, ukubambisana kwe-axial phakathi kwe-bearing yendawo kanye nezingxenye ezihambisanayo kufanele kunqunywe ngokuhambisana nezimo ezithile zesistimu yokuthwala okungeyona indawo.Indandatho yangaphakathi yokuthwala inqunyelwe isinyathelo somkhawulo wesikhundla sokuthwala (ihlombe le-shaft) ku-shaft kanye nendandatho yokugcina i-bearing, futhi indandatho yangaphandle ye-bearing ilawulwa ukubekezelelana kwe-bearing kanye ne-bearing chamber, ukuphakama ubude bezimbobo zangaphakathi nezangaphandle zokuthwala, nobude bekamelo lokuthwala.

(1) Uma isiphetho esintantayo sikhetha i-axial ehlukanisekayo namasongo angaphakathi nangaphandle, amasongo angaphandle ama-bearings emikhawulweni yomibili athatha ukulingana okungenayo i-axial clearance-free.

(2) Lapho i-axial engahlukaniseki ikhethelwa ukuphela okuntantayo, ubude obuthile be-axial clearance bugcinwa phakathi kweringi langaphandle le-axial nomphetho wesembozo sokuthwala, kanye nokulingana phakathi kweringi elingaphandle negumbi lokuthwala. akulula ukucinana kakhulu.

(3) Uma injini ingenaso isiphetho esicacile sokuma nesiphetho esintantayo, amabhola e-deep groove asetshenziswa ngokuvamile emikhawulweni yomibili, futhi ubudlelwano bokubambisana phakathi kweringi yangaphandle yomkhawulo kanye nekhava yangaphakathi ibambekile, futhi kune-axial. igebe phakathi kwesembozo sangaphandle nesembozo sangaphandle;Noma akukho imvume ye-axial phakathi kwendandatho yangaphandle yokuthwala emikhawulweni yomibili kanye nesembozo sangaphandle se-axial, futhi kukhona imvume ye-axial phakathi kwesembozo sangaphakathi nesembozo sangaphakathi.

Ubudlelwano obufanayo obungenhla buwubudlelwano obunengqondo obususelwe ekuhlaziyweni kwethiyori.Ukucushwa kwangempela kokuthwala kufanele kufane nezimo zokusebenza zenjini, kufaka phakathi imingcele ethile efana nokucaciswa, ukumelana nokushisa, nokunemba ekukhetheni ama-motor bearings, kanye nama-bearings.Ubudlelwano be-radial fit ne-bearing chamber, njll.

Kumele kuqashelwe ukuthi ukuhlaziya okungenhla kungokwamamotho afakwe ngokuvundlile kuphela, kodwa kumamotho afakwe mpo, kumele kube nezidingo ezithile mayelana nokukhethwa kwama-bearings kanye nobudlelwano obuhambisanayo obuhambisanayo.
