Ukukhathala kwe-dimples kwiibherethi eziqengqelekayo ngenxa yomthwalo ogqithisileyo we-static zifana ne-dimples ezibangelwa ngamasuntswana angaphandle, kwaye imida yazo ephakanyisiweyo ingakhokelela ekungaphumeleli.I-Phenomenon: Kwinqanaba lokuqala, imingxuma esasazwayo kunye ne-rolling element spacing idla ngokusasazwa kuphela kwinxalenye ye-circumference, ekugqibeleni ikhokelela ekubonakaleni kweentanda.Ngamanye amaxesha oku kwenzeka nge-ferrule enye kuphela.Ihlala i-asymmetrical embindini wendlela yomdyarho.Oonobangela: - Imithwalo emileyo egqithisileyo, imithwalo eyothusayo - Amandla anyukayo asasazwa ngezinto eziqengqelekayo Isicombululo: - Landela imiyalelo yofakelo - Kunqande ukugcwala kunye nemithwalo eyothusayo egqithisileyo Iziganeko zokudinwa ngenxa yokunyuswa ngendlela engafanelekanga: Kwiibheringi zebhola zoqhagamshelwano ngokubanzi, kukho ukudinwa indawo engeyiyo yoqhagamshelwano kufuphi nembambo encinci, jonga uMzobo 46. Izizathu: - Ulungelelwaniso olungafanelekanga - Uqhagamshelwano lwe-axial olunganelanga okanye iibholiti zokutshixa zingaqiniswanga - Ukuphazamiseka kwe-radial kakhulu Isisombululo: - Qinisekisa ukuqina kwamacandelo ajikelezileyo - Ufakelo oluchanekileyo Ukukhathala ngenxa yokungahambi kakuhle : – Track off-centre of bearing , jonga umfanekiso 40 – Ukudinwa kwi-raceway/rolling element edges, jonga umzobo 47 – Iigrooves ezijikelezayo ezibangelwa yi-deformation yeplastiki kuwo wonke okanye inxalenye yomhlaba, ngoko imida igudileyo.Kwiimeko ezigqithisileyo, kuya kubakho iintanda ezantsi kwegroove, jonga uMzobo 48.

Isizathu: Ngenxa yokungahambi kakuhle kwezindlu okanye ukuphambuka kwe-shaft, i-ring yangaphakathi idityaniswe ngokumalunga nendandatho yangaphandle kwaye ibangela imithwalo yomzuzu omkhulu.Kwimibhobho yebhola, oku kubangela amandla kwiipokotho zekheji (icandelo 3.5.4), ukutyibilika ngakumbi kwiindlela zomdyarho kunye neebhola ezibaleka emaphethelweni eendlela zomdyarho.Kwiibherengi ze-roller, i-raceway ilayishwe ngokulinganayo.Xa umsesane uthambekele ngokunzulu, umda wendlela yomjaho kunye nezinto eziqengqelekayo ziya kuthwala umthwalo, kwaye ukuxinzezeleka koxinzelelo kuya kwenzeka.Nceda ubhekiselele “kumzila wokungahambi kakuhle” kwisahluko 3.3.1.2.Amanyathelo okulungisa: -Sebenzisa iibheringi ezizilungelelanisayo-Nciphisa ukungahambi kakuhle-Phucula amandla e-shaft 31 Vavanya iimpawu zokuqhuba kunye nomonakalo wokudinwa kweebheringi ezisusiweyo.I-48: Ukudinwa kwenzeka kumda wogqatso lwebhola, njengomthwalo wemizuzu ephezulu (i-edge runing);umfanekiso osekhohlo ubonisa isiphelo sendlela yomdyarho, kwaye umfanekiso osekunene ubonisa ibhola.
