Ngokokuzungezisa komthwalo osebenza ekuthwaleni okuhlobene neringi, kunezinhlobo ezintathu zemithwaloi-rolling bearamabhere ayindandatho: umthwalo wendawo, umthwalo we-cyclic, nomthwalo we-swing. Ngokuvamile, umthwalo we-cyclic (umthwalo wokujikeleza) kanye nomthwalo we-swing usebenzisa ukulingana okuqinile; ngaphandle kwezidingo ezikhethekile zemithwalo yasendaweni, ngokuvamile ayifaneleki ukusebenzisa ukulingana okuqinile. Lapho iringi eginqikayo ingaphansi komthwalo oguquguqukayo futhi iwumthwalo osindayo, izindandatho zangaphakathi nezingaphandle kufanele zisebenzise ukulingana kokuphazamiseka, kodwa ngezinye izikhathi iringi yangaphandle ingase ixege kancane, futhi kufanele ikwazi ukuhamba nge-axially endlini yokuthwala. umgodi wezindlu; lapho Uma indandatho yokuthwala ingaphansi kwemithwalo e-oscillating futhi umthwalo ulula, ukulingana okuxekethile kancane kunokulingana okuqinile kungasetshenziswa.

Usayizi wokulayisha

Ukuphazamiseka phakathi kweringi yokuthwala kanye ne-shaft noma imbobo yezindlu kuncike kusayizi womthwalo. Uma umthwalo unzima, kusetshenziswa ukulingana okukhulu kokuphazamiseka; lapho umthwalo ulula, ukulingana okuncane kokuphazamiseka kuyasetshenziswa. Ngokuvamile, lapho umthwalo we-radial P ungaphansi kuka-0.07C, ungumthwalo omncane, lapho u-P mkhulu kuno-0.07C futhi ulingana noma ungaphansi kuka-0.15C, ungumthwalo ovamile, futhi uma u-P mkhulu kuno-0.15C, kuwumthwalo osindayo (C umthwalo oguquguqukayo olinganiselwe wokuthwala).

Izinga lokushisa lokusebenza

Lapho ukuthwala kusebenza, izinga lokushisa le-ferrule livame ukuphakama kunokushisa kwezingxenye eziseduze. Ngakho-ke, indandatho yangaphakathi yokuthwala ingase ikhululeke nge-shaft ngenxa yokwanda okushisayo, futhi indandatho yangaphandle ingase ithinte ukunyakaza kwe-axial yokuthwala emgodini wezindlu ngenxa yokwanda okushisayo. Lapho ukhetha ukulingana, umehluko wezinga lokushisa kanye nokwandiswa nokufinyela kwedivayisi ephethe kufanele kucatshangelwe. Uma umehluko wezinga lokushisa mkhulu, ukuphazamiseka kokulingana phakathi kwe-shaft nendandatho yangaphakathi kufanele kube kukhudlwana.

Ukunemba kokuzungezisa

Uma ukuthwala kunezidingo zokunemba okuphezulu kokujikeleza, ukuze kuqedwe umthelela wokuguquguquka okunwebekayo nokudlidliza, ukusetshenziswa kokulingana kwemvume kufanele kugwenywe.

Isakhiwo kanye nempahla ye-bearing house bore

Ngomgodi wezindlu ohlelekile, akufanelekile ukusebenzisa ukungenelela kokuphazamiseka lapho kuhlangana nendandatho yangaphandle ephethe, futhi indandatho yangaphandle akufanele ijikelezwe emgodini wezindlu. Kuma-bearings agxunyekwe odongeni oluncane, insimbi ekhanyayo, noma i-hollow shafts, kufanele kusetshenziswe ukulingana okuqinile kunodonga oluwugqinsi, i-cast-iron, noma imishayo eqinile.

Ukufakwa okulula nokuqaqa

Emishinini enzima, ukulingana okuxekethile kufanele kusetshenziselwe ama-bearings. Uma kudingeka ukulingana okuqinile, i-bearing ehlukanisekayo, i-tapered bore iringi yangaphakathi kanye ne-bearing ene-adapter sleeve noma umkhono wokuhoxiswa kungakhethwa.

Ukususwa kwe-axial ye-bearing

Ngesikhathi sokulingana, lapho indandatho ye-bearing idingeka ukuze ikwazi ukuhamba nge-axially ngesikhathi sokusebenza, indandatho yangaphandle ye-bearing kanye nembobo yezindluukuzalaindlu kufanele ithathe ukulingana okuxekethile.

Ukukhetha kufanelekile

Ukumatanisa phakathi kwe-bearing and shaft kusebenzisa i-base hole system, futhi ukufanisa nezindlu kusebenzisa uhlelo lwe-base shaft. Ukulingana phakathi kwe-bearing kanye ne-shaft kuhlukile ohlelweni lokubekezelelana olusetshenziswa embonini yokukhiqiza umshini. Indawo yokubekezelela yobubanzi obungaphakathi bokuthwala ingaphansi koshintsho. Ngakho-ke, ngaphansi kwezimo zokulingana okufanayo, isilinganiso esifanelekile sobubanzi obungaphakathi be-bearing kanye ne-shaft ngokuvamile siqinile. . Yize indawo yokubekezelela yobubanzi obungaphandle be-bearing kanye nendawo yokubekezelela yesistimu ye-shaft eyisisekelo zombili zingaphansi komugqa we-zero, amanani azo awafani nohlelo olujwayelekile lokubekezelelana.
