Chikonzero chikuru chemechani ruzha: Iyo mechanic ruzha inogadzirwa nevatatu-phase asynchronous motainonyanya kuita ruzha rwekukanganisa. Pasi pechiito chesimba rekutakura, chikamu chimwe nechimwe chekutakura chakaremara, uye kushushikana kunokonzerwa nekutenderera kwekuchinja kana frictional vibration yezvikamu zvekutapurirana ndiko kunobva ruzha rwayo. Kana iyo radial kana axial clearance yekubereka iri diki zvakanyanya, iyo rolling friction inowedzera, uye simbi extrusion simba inogadzirwa panguva yekufamba. Kana gomba racho rakanyanya kukura, haringangoiti kuti kutakura kusimbiswe zvisina kufanana, asiwo kuchinja mhepo yemhepo pakati pe stator uye rotor, nokudaro kuwedzera ruzha, kukwira kwekushisa uye kudengenyeka. Iyo yekutakura mvumo ndeye 8-15um, iyo yakaoma kuyera pane saiti uye inogona kutongwa nekunzwa kwemaoko.
Pakusarudza mabearings, unofanira kufunga nezve: (1) Kudzikiswa kwemukaha unokonzerwa nekubatana kwefaniro nekavha yekugumisira. (2) Pakushanda, musiyano wetembiricha pakati pemhete dzemukati nedzekunze unokonzera kuti gwanza richinje. (3) Mukaha pakati pe shaft uye yekupedzisira chivharo chinoshanduka nekuda kweakasiyana ekuwedzera coefficients. Upenyu hwakarongerwa hwekutakura ndeye 60000h, nekuda kwekushandiswa kusina kunaka nekugadzirisa, hupenyu chaihwo hunobudirira hwebasa ndeye 20-40% chete yehuwandu hwehuwandu.
Kudyidzana pakati peberengi neshaft kunotora buri rekutanga, kushivirira kwedhayamita yemukati meberengi kwakaipa, uye kubatana kwakasimba. Bearings nemajenari zvinogona kukuvadzwa zviri nyore panguva yekuungana pasina hunyanzvi hwakakodzera uye maturusi. Bearings dzinofanira kubviswa neanokosha anodhonza.
Kutonga kwekubereka ruzha:
1. Pane girizi yakawandisa mubereko, pachava nesando yemvura inonzwika pakati nepakati uye yakaderera, uye isina kuenzana inonzwika furo pakumhanya kukuru; izvi zvinokonzerwa nekukweshana kwakawedzera kwemamorekuru emukati nekunze pasi pekusagadzikana kwebhora, zvichikonzera kuderedzwa kwegirisi ye. Giresi rakanyungudutswa rakadonhera pa stator windings, richidzivirira kuti risatonhore uye richikanganisa kudzivirira kwayo. Kazhinji, zadza 2/3 yenzvimbo inotakura negirizi. Pachava neruzha kana kutakura kwapera mafuta, uye pachava nekutinhira nezviratidzo zvekusvuta nekukurumidza.
2. Apo kusvibiswa kwemafuta kunounzwa mukutakura, manzwi anopindirana uye asina kukwana anogona kubudiswa, izvo zvinokonzerwa nekusagadzikana kwechinzvimbo chekusvibiswa kunotungamirirwa nemabhora. Zvinoenderana nenhamba, kusvibiswa kwegirisi kunokonzeresa 30% yezvinokonzeresa kutakura kukuvara.
3. Kune periodic "click" inzwi mukati mekutakura, uye zvakaoma zvikuru kuishandura nemaoko. Zvinofanira kufungidzirwa kuti kune kumwe kukoromoka kana kubvarura pamujaho. Kunonzwika "kukachidzwa" mumabearings, kutenderera kwemaoko kunogona kunge kune nzvimbo dzisina kumira dzakafa, zvichiratidza mabhora akatyoka kana kukuvara kwebhora.
4. Kana kusununguka kweshaft uye kutakura hakusi kwakakomba, pachava nekusagadzikana kwesimbi. Kana mhete yekunze inotakura ichikambaira mugomba rekuvhara kwekupedzisira, inoburitsa yakasimba uye isina kuenzana yakaderera-frequency ruzha uye vibration (iyo inogona kunyangarika mushure mekurodha radial).
