Ukukhathala kwama-dimples kuma-rolling bearings ngenxa yemithwalo ye-static ngokweqile kufana nama-dimples abangelwa izinhlayiya zangaphandle, futhi imiphetho yawo ephakanyisiwe ingaholela ekuhlulekeni.I-Phenomenon: Esigabeni sokuqala, imigodi esabalaliswa ngezikhala ze-elementi eginqikayo ivamise ukusabalalisa ingxenye yesiyingi, okuholela ekubonakaleni kwemifantu.Lokhu ngezinye izikhathi kwenzeka nge-ferrule eyodwa kuphela.Imvamisa i-asymmetrical enkabeni yomgwaqo womjaho.Izimbangela: - Imithwalo emile eyeqile, imithwalo eshaqisayo - Amandla akhuphukayo adluliswa ngezinto eziginqikayo Ikhambi: - Landela imiyalelo yokufaka - Gwema ukugcwala ngokweqile kanye nemithwalo yokushaqeka eyeqile Izimo zokukhathala ngenxa yokukhwezwa okungalungile: Kumabhola okuxhumana angu-angular Ngokuvamile, kukhona ukukhathala indawo engathinteki eduze nombambo oluncane, bheka uMfanekiso 46. Izimbangela: - Ukulungiswa okungalungile - Ukuthintana kwe-axial okwanele noma amabhawodi wokukhiya angaqinisiwe - Isixazululo sokuphazamiseka kwe-radial kakhulu: - Qinisekisa ukuqina kwezingxenye ezizungezile - Ukufakwa kahle Ukukhathala ngenxa yokungahambi kahle : – Landela off-centre of bearing , bheka Fig. 40 – Ukukhathala on raceway/rolling element emaphethelweni, bheka Fig. 47 – Circumferential grooves okubangelwa deformation plastic on the whole or part of the surface, ukuze imiphetho bushelelezi.Ezimweni ezimbi kakhulu, kuzoba nemifantu ngaphansi kwe-groove, bheka uMfanekiso 48.

Imbangela: Ngenxa yokungahambi kahle kwendlu noma ukuchezuka kwe-shaft, iringi yangaphakathi itshekile ngokuhlobene nendandatho yangaphandle futhi ibangele imithwalo yesikhashana emikhulu.Kumabhola ama-bearings, lokhu kubangela amandla emaphaketheni ekheji (isigaba 3.5.4), ukushelela kakhulu emigwaqweni yomjaho kanye namabhola agijima emaphethelweni emigwaqo yomjaho.Kuma-roller bearings, umzila womjaho ulayishwe ngokulinganayo.Lapho indandatho ithambekele ngokungathi sína, unqenqema lomjaho kanye nezakhi ezigoqayo zizothwala umthwalo, futhi ukugxila kokucindezeleka kuzokwenzeka.Sicela ubhekisele “kuthrekhi yokungaqondi kahle” esahlukweni 3.3.1.2.Izinyathelo zokulungisa: - Sebenzisa ama-bearings aziqondanisayo - Yehlisa ukungahambi kahle - Thuthukisa amandla e-shaft 31 Linganisa izici ezisebenzayo kanye nokulimala kokukhathala okususiwe.48: Ukukhathala kwenzeka emaphethelweni omgwaqo othwala ibhola, njengokuthwala isikhashana eside (ukugijima onqenqemeni);isithombe esingakwesokunxele sibonisa unqenqema lomjaho, kanti isithombe sokudla sikhombisa ibhola.
