Kunyangwe iyo yekutakura yekushanda clearance yakakura kana idiki pane yekumisikidza clearance zvinoenderana neyakasanganiswa mhedzisiro yezvinhu zviviri izvi.

Mamwe mabhengi anotenderedzwa haagone kugadziridzwa kuti asunungurwe, ndoda kubviswa.Mabearings aya ane marudzi matanhatu, anoti type 0000 to type 5000;mamwe mabearings anotenderedza anogona kugadzirisa clearance, asi haigone kubviswa.1000 mhando, 2000 mhando uye 3000 mhando rolling bearings, kuisirwa kubvumidzwa kweaya marudzi ekutenderera mabhengi kuchave kudiki pane yepakutanga clearance mushure mekugadzirisa;uyezve, mamwe mabearings anogona kupatsanurwa, uye clearance inogona kugadziriswa, pane 7000 type (tapered roller bearings)), 8000 type (thrust ball bearing) uye 9000 type (thrust roller bearing), aya matatu marudzi emabearings haaiti. kuve nemvumo yepakutanga;6000 mhando uye 7000 mhando yekutenderedza mabheji, iyo radial clearance yakaderedzwa, iyo axial clearance Inovawo idiki, uye zvinopesana, nepo Type 8000 uye Type 9000 rolling mabearings, chete axial clearance ine kukosha kunoshanda.

Yakakodzera yekumisikidza clearance inobatsira kune yakajairika mashandiro eku rolling bearings.Kana iyo kucheneswa kuri kudiki, kutonhora kweiyo rolling bearing kuchakwira, uye hakuzoshandi zvakanaka, uye kunyange zvinhu zvinoputika zvichange zvakanamatira;kana iyo clearance yakakurisa, mudziyo uchadedera zvakanyanya, uye kutenderera kuchaita ruzha.

Iyo nzira yekuongorora yeradial clearance ndeiyi inotevera:

1. Manzwiro maitiro

1. Kune ruoko rwekutenderera kubereka, uye kutakura kunofanira kugadzikana uye kushanduka pasina jamming.

2. Kuzunungusa mhete yekunze yekutakura nemaoko, kunyange kana radial clearance iri 0.01mm chete, kufamba kweaxial kwepamusoro-soro yekutakura ndeye 0.10 ~ 0.15mm.Iyi nzira yakatsaurirwa kune imwechete mutsara radial bhora mabhengi.

2. Kuyera nzira

1. Tarisa nejini yekunzwa kuti usimbise nzvimbo yepamusoro yekuremerwa kweiyo rolling bearing, isa feeler gauge pakati pechinhu chinotenderedza uye yekunze (yemukati) mhete pa180 °, uye ukobvu hweiyo feeler geji ine elasticity yakakodzera ndiyo radial. clearance of the bear.Iyi nzira inoshandiswa zvakanyanya mu spherical bearings uye cylindrical roller bearings.

2. Tarisa negeji yedhiyabhorosi, tanga waisa dial gauge kusvika zero, wobva wajaidza ring yekunze yekutenderedza.Kuverenga kwedhiyabhorosi gauge ndiko kubviswa kweradial yekutakura.

Nzira yekuongorora yeaxial clearance ndeiyi inotevera:

1. Manzwiro maitiro

Shandisa zvigunwe zvako kutarisa axial clearance ye rolling bearings.Iyi nzira inofanira kushandiswa kana shaft inopera ichionekwa.Kana iyo shaft yakavharwa kana kuti haigone kuongororwa neminwe kune zvimwe zvikonzero, inogona kuongororwa kana shaft inotenderera zvakasununguka.

2. Kuyera nzira

(1) Tarisa ne feeler gauge, nzira yekushanda yakafanana neyekutarisa radial clearance ine feeler gauge, asi iyo axial clearance inofanirwa kunge iri.

c=λ/(2sinβ)

uko c——axial clearance, mm;

λ—— ukobvu hwegeji yekunzwa, mm;

β——Iine taper angle, (°).

(2) Tarisa nedhiyabhorosi.Kana shaft ichifambiswa necrowbar kuita shaft munzvimbo mbiri dzakanyanyisa, mutsauko uripo pakati peiyo dial gauge kuverenga ndeye axial clearance yekutakura.Zvisinei, simba rinoshandiswa kune crowbar harifaniri kunge rakanyanya kukura, zvikasadaro casing ichave yakasvibiswa, uye kunyange kana deformation idiki, inokanganisa kururamisa kwekuyera kweaxial clearance.
