Chii chinonzi clearance uye clearance inoyerwa sei pama rolling bearings?

Kubviswa kwebearing rinotenderera ihuwandu hwebasa rinobata rin'i imwe panzvimbo uye imwe iri mudivi reradial kana axial. Basa guru riri mudivi reradial rinonzi radial clearance, uye basa guru riri mudivi reaxial rinonzi axial clearance. Kazhinji, kana radial clearance yakakura, axial clearance yakakura, uye zvinopesana. Zvichienderana nemamiriro ebearing, clearance inogona kukamurwa mumhando nhatu dzinotevera:

I. Chibvumirano chekutanga

Kubviswa kwemahara kwebheyari usati waisa. Kubviswa kwekutanga kunotsanangurwa nekugadzirisa uye kuunganidza kwemugadziri.

2. Isa nzvimbo yekubvumidza

Inozivikanwawo se fit clearance, ndiyo clearance kana bearing ne shaft ne bearing housing zvaiswa asi zvisati zvashanda. ...

3. Kubvumidzwa kwebasa

Kana bearing iri kushanda, tembiricha yemukati memhete inokwira kusvika pakakwirira uye kuwedzera kwekupisa kusvika pakakwirira, zvekuti nzvimbo yebearing inoderera. Panguva imwe chete, nekuda kwemutoro, elastic deformation inoitika panzvimbo yekubatana pakati pemuviri unotenderera nemugwagwa wemujaho, izvo zvinowedzera nzvimbo yebearing. Kana nzvimbo yebearing iri yakakura kana kuti diki pane nzvimbo yekuisa zvinoenderana nemhedzisiro yezvinhu zviviri izvi.

Mamwe mabheyaringi anotenderera haagone kugadziriswa kana kuparadzaniswa. Anowanikwa mumhando nhanhatu, kubva pa0000 kusvika 5000; Kune mhando 6000 (angular contact bearings) uye mhando 1000, Type 2000 uye Type 3000 ine maburi ekoni murin'i yemukati. Kubviswa kwemhando idzi dzemabheyaringi anotenderera, mushure mekugadzirisa, kuchava kudiki pane kubviswa kwekutanga. Pamusoro pezvo, mamwe mabheyaringi anogona kubviswa, uye kubviswa kunogona kugadziriswa. Kune mhando nhatu dzemabheyaringi: Type 7000 (tapered roller bearing), type 8000 (thrust ball bearing) uye mhando 9000 (thrust roller bearing). Hapana clearance yekutanga mumhando nhatu idzi dzemabheyaringi. Kune mhando 6000 uye 7000 rolling bearings, radial clearance inoderedzwa uye axial clearance inoderedzwawo, uye zvinopesana, nepo kune mhando 8000 uye 9000 rolling bearings, axial clearance chete ndiyo inokosha.

Kubviswa kwakakodzera kwekuisa kunoita kuti zvive nyore kushanda zvakanaka kwebheya rinotenderera. Nzvimbo yacho idiki kwazvo, tembiricha yebheya rinotenderera inokwira, haigone kushanda zvakanaka, zvekuti muviri unotenderera unonamira; Kubviswa kwakanyanya, kudedera kwemidziyo, ruzha rwebheya rinotenderera.

Nzira yekuongorora clearance ye radial ndeiyi inotevera:

I. Nzira yekunzwa

1. Nekutenderera kweruoko, bearing inofanira kunge yakatsetseka uye inochinjika isina kunamira uye isina kusimba.

2. Zunza rin'i yekunze yebearing neruoko. Kunyangwe kana nzvimbo ye radial iri 0.01mm chete, kufamba kwe axial kwenzvimbo yepamusoro yebearing ndeye 0.10-0.15mm. Nzira iyi inoshandiswa kune ma single row centripetal ball bearingers.

Nzira yekuyera

1. Tarisa uye simbisa nzvimbo yepamusoro yekutakura kwebearing inotenderera uchishandisa feeler, isa feeler pakati pemuviri unotenderera 180° nering yekunze (yemukati), uye ukobvu hwakakodzera hwefeeler i radial clearance yebearing. Nzira iyi inoshandiswa zvakanyanya mumabearing anozvimiririra uye mabearing e cylindrical roller.

2, tarisa nechiratidzo chedhayari, tanga waisa chiratidzo chedhayari pazero, wobva wasimudza rin'i yekunze yebheyaringi rinotenderera, kuverenga kwechiratidzo chedhayari ndiko kuchena kwebheyaringi.

Nzira yekuongorora yekubvisa axial ndeiyi inotevera:

1. Nzira yekunzwa

Tarisa nzvimbo yekubata bhora nemunwe wako. Nzira iyi inofanira kushandiswa kana mugumo weshaft waonekwa. Kana mugumo weshaft wakavharwa kana kuti usingakwanise kuongororwa neminwe nekuda kwezvimwe zvikonzero, tarisa kana shaft yacho ichichinjika pakutenderera.

2. Nzira yekuyera

(1) Tarisa nefeeler. Nzira yekushandisa yakafanana neyekutarisa radial clearance nefeeler, asi axial clearance inofanira kunge iri

C = lambda/sin (2 beta)

Kupi c -- nzvimbo ye axial, mm;

-- Ukobvu hwegeji, mm;

-- Koni yebheyaringi Angle, (°).

(2) Tarisa uchishandisa chiratidzo chedhiraivha. Kana bhaa remagetsi richishandiswa kutenderedza shaft inofamba kuenda kunzvimbo mbiri dzakanyanya, musiyano wekuverenga chiratidzo chedhiraivha ibviro rebhiari. Zvisinei, simba rinoshandiswa pabhaa remagetsi harifanirwe kunge rakakura zvakanyanya, zvikasadaro ganda racho richava nekushanduka-shanduka, kunyangwe kana kushanduka kwacho kuri kudiki kwazvo, zvichakanganisa kururama kwebviro remagetsi rakayerwa.
