A cikin ƙarshe, mun gabatar da abubuwa biyu na farko. A nan, muna mai da hankali kan sauran abubuwa guda uku da ke tasiri a ƙararrawa ta jiki a cikin allon ɗin rawar kai.

Nesa na Ciki na Jirgin

Kauri mai girma ko kuma ƙanana sosai na tsammanin cikin radial zai haifar da motsin girgiza mai ƙarfi a cikin bearings. Tsammani cikin radial da ya yi ƙanƙanta sosai yana haifar da motsin girgiza mai ƙaraɗi a yanda zai yi saurin gudu Mai yawa, kuma tsammani cikin radial da ya yi girma sosai yana haifar da motsin girgiza mai ƙasa da saurin gudu. Tsammani cikin radial da ya yi girma sosai zai rage ƙaƙƙarfan ƙimar ƙaraɗi na tsarin elasticity na bearings. Yana da sauƙi a haifar da girgiza mai sanyi da kuma haifar da girgiza mai ƙarfi da ƙananan saurin gudu. Wannan saboda zai haifar da babban saurin ƙaruwa a wurin da ke shafar kayan juyawa da ferrule.

A cewar gwaji da bincike, babban ko daurewar ciki na radial zai haifar da karfin jijjiga mai ƙarfi a cikin jikin bearings. Kuma idan ƙarfin ciki na radial ya yi ƙanƙanta sosai, saboda ƙarfi na radial yana da girma, saboda haka ƙonewar ƙona zafin jiki yana ƙaruwa da sauri, wanda zai haifar da ƙona bearings a zafin jiki mai yawa. Baya ga haka, mai riƙe zai haifar da babban watsin radial tare da ƙaruwa na ƙarfin ciki na radial, wanda daga baya ke haifar da jijjiga mai ƙarfi.

Hadin Gwiwa

Hadin gwiwar zobe na waje da ramin mai dauke zai shafi jigilar jijjiga. Irin wannan matakin da ya yi ƙyamar sanyi zai tilasta wa hanyar gudu ta sauya sifarta da kuma hanzarta ganin kurakuran siffofi, yana sa jijjiga ta zama mafi tsananin. Hadin gwiwar da bai yi matuƙar karko ba zai sa fim ɗin mai a cikin filin zamewa ya samar da aiwatar da maganin baka.

Matsalar Gagarumin da Mannewa

Buraloli sune babban tushen rawa wanda yake da wahalar kulawa a allon rawar da ke rawa. Tunda allon rawar na aiki ne ta hanyar ƙarfi mai ƙarfi da aka tada, don haka buraloli suna ƙarƙashin babban ƙarfi mai zagaye. A cikin aikin allon rawar, ƙarfin da aka tada zai jawo farkawar elasticity na buraloli. Idan buralolin suna da rashin mai kyau na masana'anta, zai haifar da babban zamewa, hakan na ƙara girma yawan zafi a kan buraloli sosai.

A wannan yanayi, ragewar sararin ciki na cikin radial yana raguwa sosai, yana sa gogayya ta bunkasa da sauri kuma yana sa zafin jiki ya tashi. Saboda haka, masu ƙera da yawa suna amfani da babban sararin ciki na cikin radial a fuskar allon rawa. Amma kuma, babban sararin ciki na cikin radial yana ragewa daidaiton ƙarfi na halitta na bearings kuma yana ƙara yuwuwar radial runout na rolling element. A lokaci guda, ƙarfin tasirin da ke kan ferrule zai kuma ƙaru yayin runout na rolling element, wanda zai ƙara girman ɗaukar sautin rawar jiki na rarrabuwa da kuma haifar da rawar jikin high-frequency mai ƙarfi.
