Ijubane le-motor bearing lilinganiselwe ngokuyinhloko ukunyuka kwezinga lokushisa okubangelwa ukungqubuzana nokushisa ngaphakathi kwemodeli yokuthwala.Uma ijubane lidlula umkhawulo othile, i-arekta ngeke ikwazi ukuqhubeka nokuphenduka ngenxa yokusha, njll. ukusha.Ngakho-ke, isivinini esinqunyelwe sokuthwala sincike ezintweni ezihlukahlukene ezifana nohlobo, ubukhulu kanye nokunemba kokuthwala, indlela yokugcoba, ikhwalithi kanye nenani lokugcoba, into kanye nohlobo lwekheji, nezimo zomthwalo.

Izivinini ezinqunyelwe zamabheringi ahlukahlukene kusetshenziswa ukugcotshwa kwamafutha kanye nokuthambisa uwoyela (ukugcoba ukugeza uwoyela) kufakwe kuhlu kuthebula losayizi wokuthwala ngalinye.Amanani amelela ama-bearings aklanyelwe ajwayelekile ngaphansi kwezimo ezijwayelekile zokulayisha (C/P≥13, Fa/Fr≤0.25 noma ngaphezulu ) inani elilinganiselwe lejubane lokuzungezisa lapho lizungezisa ngesivinini esiphansi.Ukulungiswa kwesivinini somkhawulo: isimo somthwalo C/P <13 (okungukuthi, umthwalo oguqukayo olinganayo P weqa cishe u-8% wesilinganiso esiyisisekelo somthwalo oguqukayo C), noma lapho umthwalo we-axial emthwalweni ohlanganisiwe weqa u-25% womthwalo weradial , kufanele Isebenzise isibalo (1) ukulungisa isivinini somkhawulo.na=f1·f2·n……………(1) Umkhawulo olungisiwe, i-rpm, i-coefficient yokulungisa ehlobene nesimo somthwalo (Fig. 1), i-coefficient yokulungisa ehlobene nomthwalo womphumela (Fig. 2), isivinini somkhawulo ngaphansi kwezimo zomthwalo ojwayelekile, i-rpm (bheka ithebula losayizi wokuthwala) isilinganiso somthwalo oguqukayo oyisisekelo, N{kgf} umthwalo olinganayo oguqukayo, N{kgf} umthwalo we-radial, N{kgf} i-axial load, N{kgf} i-pole motor kanye nesivinini esikhulu sokuzungezisa Izinyathelo Zokuqapha: Ama-Bearings lapho uzungezisa phezulu. isivinini, ikakhulukazi uma isivinini siseduze noma sedlula u-70% wesivinini esilinganiselwe esirekhodwe kuthebula lobukhulu, lezi zindaba ezilandelayo kufanele zinakwe: (1) Sebenzisa ama-bearings anembe kakhulu (2) Hlaziya imvume yangaphakathi ye-bearing. (cabanga ngokukhuphuka kwezinga lokushisa ngaphakathi kwebheringi) Ukwehliswa kokususwa) (3) Hlaziya uhlobo lwempahla yekheji (4) Hlaziya indlela yokugcoba.
