M'zochita, kunyamula kuwonongeka kapena kulephera nthawi zambiri kumakhala chifukwa cha kuphatikiza kwa njira zingapo zolephera.Chifukwa cha kulephera kwapang'onopang'ono kungakhale chifukwa cha kuyika kapena kukonza kosayenera, zolakwika pakupanga kupanga ndi zigawo zake zozungulira;nthawi zina, zingakhalenso chifukwa kuchepetsa mtengo kapena kulephera kuneneratu molondola kubala mikhalidwe ntchito.

Phokoso ndi Kugwedezeka

Zovala zonyamula.Zomwe zimayambitsa kutsetsereka Ngati katunduyo ndi wochepa kwambiri, torque mkati mwazonyamulayo idzakhala yaying'ono kwambiri kuti isayendetse zinthu zozungulira, zomwe zimapangitsa kuti zinthu zogubuduza ziziyenda panjira yothamanga.Katundu wocheperako: mpira wokhala ndi P/C = 0.01;chogudubuza chokhala ndi P/C = 0.02.Poyankha vutoli, njira zomwe zatengedwa zikuphatikiza kugwiritsa ntchito axial preload (preload spring-ball bearing);ngati kuli kofunikira, kuyesa kotsegula kuyenera kuchitidwa, makamaka kwa mayendedwe a cylindrical roller, kuonetsetsa kuti mayesero ali pafupi ndi zochitika zenizeni zogwirira ntchito;onjezerani mafuta Pazifukwa zina, kuwonjezereka kwamafuta kumatha kuchepetsa kuchepa kwakanthawi (muzinthu zina);gwiritsani ntchito mayendedwe akuda, koma osachepetsa phokoso;sankhani mayendedwe okhala ndi mphamvu yotsika.

Kuwonongeka kwa kukhazikitsa.Kupanikizika kwapamtunda komwe kumachitika chifukwa cha kuyikako kumayambitsa phokoso pamene kunyamula kukuyenda ndikukhala chiyambi cha kulephera kwina.Vutoli ndilofala kwambiri m'mizere yolekanitsa.Pofuna kupewa kuchitika kwa mavuto ngati amenewa, tikulimbikitsidwa kuti tisakankhire mu cylindrical wodzigudubuza kubala mwachindunji pa unsembe, koma pang'onopang'ono atembenuza ndi kukankhira mkati, amene angachepetse kutsetsereka wachibale;ndizothekanso kupanga chowongolera chowongolera, chomwe chingapewe bwino njira yoyika.bumpu.Kwa mayendedwe ozama a mpira, mphamvu yokwera imayikidwa pa mphete zolimba, kupeŵa mphamvu yowonjezera kupyolera muzinthu zogudubuza.

Kulowetsedwa kwa Brinell zabodza.Chizindikiro cha vuto ndi chakuti pamtunda wa mpikisanowu uli ndi ma indentation ofanana ndi kuyika kosayenera, ndipo pali ma indentation ambiri achiwiri pafupi ndi indentation yaikulu.Ndipo mtunda womwewo kuchokera ku wodzigudubuza.Izi zimachitika makamaka chifukwa cha kugwedezeka.Chifukwa chachikulu ndikuti injiniyo imakhala yokhazikika kwa nthawi yayitali kapena pamayendedwe ataliatali, ndipo kugwedezeka kwapang'onopang'ono kwanthawi yayitali kumayambitsa dzimbiri losasunthika lanjira yonyamula katundu.Njira yodzitetezera ndiyoti kukonza shaft yamoto kuyenera kukonzedwanso pamene galimotoyo imayikidwa mufakitale.Kwa ma mota omwe sanagwiritsidwepo ntchito kwa nthawi yayitali, zonyamula ziyenera kugwedezeka pafupipafupi.

Ikani eccentric.Kuyika kwa eccentric kumawonjezera kupsinjika kwa kukhudzana, komanso kumayambitsa kukangana pakati pa khola ndi ferrule ndi chodzigudubuza panthawi yogwira ntchito, zomwe zimapangitsa phokoso ndi kugwedezeka.Zomwe zimayambitsa vutoli ndi monga mitsinje yopindika, ma burrs pamtengo kapena pamapewa a nyumba yonyamula katundu, ulusi pa shaft kapena locknuts zomwe sizimakanikiza bwino nkhope yobereka, kusanja bwino, ndi zina zotero. , ikhoza kuthetsedwa mwa kuyang'ana kuthamanga kwa shaft ndi mpando wonyamula katundu, kukonza shaft ndi ulusi panthawi imodzimodzi, pogwiritsa ntchito mtedza wotsekemera kwambiri, ndi kugwiritsa ntchito chida chapakati.

Kusapaka mafuta bwino.Kuphatikiza pa kuchititsa phokoso, mafuta osakwanira amatha kuwononganso msewu wothamanga.Kuphatikizapo zotsatira za mafuta osakwanira, zonyansa ndi mafuta okalamba.Njira zodzitetezera zimaphatikizapo kusankha mafuta oyenerera, kusankha koyenera, komanso kupanga kayendedwe koyenera kamafuta ndi kuchuluka kwake.

Sewero la axial ndi lalikulu kwambiri.Kuloledwa kwa axial kwa mayendedwe a mpira wakuya ndikokulirapo kuposa chilolezo cha radial, pafupifupi 8 mpaka 10.Pamakonzedwe a zitsulo ziwiri zakuya za mpira, kudzaza kasupe kumagwiritsidwa ntchito kuchepetsa phokoso lomwe limayambitsidwa ndi chilolezo kumayambiriro kwa ntchito;ndizokwanira kuwonetsetsa kuti 1 ~ 2 zinthu zogubuduza sizikuphatikizidwa.Mphamvu ya preload iyenera kufika ku 1-2% ya Cr yomwe idavotera, ndipo mphamvu yobweretsera imayenera kusinthidwa moyenera pambuyo posintha koyambirira.
