Izinto ezilandelayo kufanele zicatshangelwe lapho kukhethwa isiphetho esingaguquki sokusekela okuthwala injini (okubizwa ngokuthi isiphetho esingaguquki semoto): (1) izidingo zokulawula ukunemba zezinto ezisetshenziswayo; (2) uhlobo lomthwalo oshayelwa injini; (3) inhlanganisela ye-axial noma i-axial force kufanele ikwazi ukumelana namandla athile. Ngokusekelwe kulezi zici ezintathu ezingenhla zokuklama, ama-deep groove ball bearings avame ukusetshenziswa njengenketho yokuqala ye-motor fixed end bear in encane futhi.izinjini ezinosayizi omaphakathi.
Ama-deep groove ball bearings yiwona asetshenziswa kakhulu ama-rolling bearings. Lapho kusetshenziswa ama-deep groove ball bearings, ukwakheka kwesistimu yokusekelwa kwe-motor ilula kakhulu futhi kulula ukuyinakekela. Ama-deep groove ball bearings asetshenziselwa ikakhulukazi ukuthwala imithwalo ye-radial, kodwa lapho ukucaciswa kwe-radial of bearing kwanda, anezici zama-angular ball bearings futhi angathwala imithwalo ehlanganisiwe ye-radial ne-axial; lapho ijubane liphezulu futhi ama-thrust ball bearings awafanele, angasetshenziswa futhi ukuthwala imithwalo ehlanzekile ye-axial. Uma kuqhathaniswa nezinye izinhlobo zamabhere anezincazelo ezifanayo kanye nobukhulu obufana namabheringi amabhola e-deep groove, lolu hlobo lokuthwala lunezinzuzo ze-coefficient ephansi ye-friction kanye nesivinini somkhawulo ophezulu, kodwa okubi ukuthi alukwazi ukumelana nomthelela futhi alufanele ukuthwala. imithwalo esindayo.
Ngemva kokufakwa kwebhola le-groove ejulile ku-shaft, ukulingana kwe-radial kwe-shaft noma izindlu kuzo zombili izinkomba kungakhawulwa ngaphakathi kwe-axial clearance range ye-bearing. Esiqondisweni se-radial, i-bearing kanye ne-shaft zisebenzisa ukulingana kokuphazamiseka, futhi i-bearing kanye ne- end cover bearing chamber noma izindlu zisebenzisa ukulingana okuncane kokuphazamiseka. Umgomo oyinhloko wokukhetha lokhu kufanelana ukuqinisekisa ukuthi imvume yokusebenza ye-bearing ingu-zero noma ingalungile kancane ngesikhathi sokusebenza kwe-motor, ukuze ukusebenza kokusebenza kwe-bearing kube ngcono. Esiqondisweni se-axial, ukulingana kwe-axial ye-bearing yendawo kanye nezingxenye ezihlobene kufanele kunqunywe ngokuhambisana nezimo ezithile zesistimu yokuthwala isiphetho esintantayo. Indandatho yangaphakathi yokuthwala inqunyelwe isinyathelo somkhawulo wesikhundla (ihlombe) ku-shaft kanye nendandatho yokugcina i-bearing, futhi iringi yangaphandle ye-bearing ilawulwa ukubekezelelana okufanelekile kwe-bearing kanye ne-bearing chamber, ukuphakama indawo yokumisa ingaphandle nengaphakathi lendlu yokuthwala, nobude bekamelo lokuthwala.
(1) Lapho isiphetho esintantayo sikhetha ibhere elihlukanisekayo elinamasongo angaphakathi nangaphandle, amasongo angaphandle ama-bearings emikhawulweni yomibili ayafaniswa ngaphandle kwe-axial clearance.
(2) Uma isiphetho esintantayo sikhetha ibhere elingahlukaniseki, ubude obuthile be-axial clearance bushiywa phakathi kweringi elingaphandle le-axial kanye nokuma kwesembozo sokuthwala, futhi ukuhlangana phakathi kweringi elingaphandle negumbi lokuthwala akufanele. qina kakhulu.
(3) Uma injini ingenaso isiphetho esicacile sokuma kanye nesiphetho esintantayo, amabhola e-deep groove ball ngokuvamile asetshenziswa emikhawulweni yomibili, futhi ubuhlobo obufanelekile buwukuthi iringi yangaphandle yebhere elilinganiselwe ikhiywa nekhava yangaphakathi futhi kukhona igebe phakathi kwendandatho yangaphandle kanye nesembozo sangaphandle ohlangothini lwe-axial; noma indandatho yangaphandle yama-bearings emikhawulweni yomibili ifaniswe ngaphandle kwe-axial clearance phakathi kwendandatho yangaphandle ye-axial kanye nesembozo sokuthwala, futhi kukhona igebe phakathi kwendandatho yangaphandle kanye nekhava yangaphakathi ekuqondeni kwe-axial.
Ubudlelwano obufanayo obungenhla bonke ubudlelwano obunengqondo obuhlaziywa ngokwethiyori. Ukucushwa kwangempela kokuthwala kufanele kuhambisane nezimo zokusebenza zenjini, okuhlanganisa imingcele ethile efana nokucaciswa, ukumelana nokushisa, ukunemba, njll. ekukhethweni kwe-motor bearing, kanye nobudlelwane obuhambisanayo be-radial phakathi kwe-bearing and the bearing chamber.
Kumele kuqashelwe ukuthi ukuhlaziywa okungenhla kungokwakho kuphelaamamotho afakwe ngokuvundlile, ngenkathi kumamotho afakwe mpo, kokubili ukukhethwa kwamabheringi nobudlelwano obuhambisanayo obuhambisanayo kufanele kube nezidingo ezithile.
