Rolling bearings suna da fa'idodi da yawa waɗanda ke sa su dace da aikace-aikacen niƙa. Na farko, jujjuyawar juzu'i ya fi ƙarami fiye da zamewar gogayya, wanda zai iya rage asarar kuzari da zafi, da haɓaka ingancin injin. Abu na biyu, motsi na mirgina bearings yana da kwanciyar hankali kuma yana iya tsayayya da manyan radial da axial lodi, yana sa su dace da motsi mai sauri mai sauri. Bugu da kari, mirgina bearings kuma suna da fa'ida kamar tsawon sabis rayuwa da kuma dace tabbatarwa.
A kan injinan ƙwallo, ana amfani da birgima yawanci don tallafawa sassan da ke ɗauke da ganga da na'urar watsawa. Za su iya tsayayya da jujjuyawar sauri da kuma tasirin tasiri daga abrasives da kayan watsa labarai, tabbatar da aikin al'ada na kayan aiki. Saboda yanayin aiki mai tsanani na ƙwallon ƙwallon ƙafa, ana buƙatar bearings don samun babban hatimi da ƙurar ƙura don hana abrasive da kafofin watsa labaru daga shiga ciki na bearings da kuma tasiri aikin su.
A takaice, aikace-aikace na zamiya bearings zuwa mirgina bearings a ball Mills iya inganta amintacce da kuma aiki yadda ya dace na kayan aiki, tsawaita rayuwar bearings, da kuma rage gyara halin kaka.
Wadannan su ne manyan lahani na bearings na zamiya:
1. Tsagewa da lalacewa: Zamewa bearings yana rage hulɗar tsakanin sassa masu zamewa da jujjuyawa ta hanyar juzu'i, amma juzu'i na iya haifar da asarar kuzari da lalacewa, ta haka rage ɗaukar rayuwa da ingantaccen aiki.
2. Babban buƙatun lubrication: Zazzage bearings suna buƙatar kula da isasshen mai don rage juzu'i da lalacewa, don haka ya zama dole don ƙarawa akai-akai da maye gurbin lubricants, wanda ke ƙara ƙimar kulawa da aikin aiki.
3. Wahala wajen samar da zafi da tarwatsewa: Saboda rashin jituwa, zamewar bearings na haifar da zafi, kuma saboda babban wurin tuntuɓar su, zafi yana raguwa. Wannan na iya haifar da zafi mai zafi na bearings da abubuwan da ke kusa da su, yana shafar kwanciyar hankali da tsawon rayuwar kayan aiki.
4. Ba dace da aiki mai sauri ba: Saboda matsi na gida da watsar da lubricants, ɗigon zamewa yana da haɗari ga gazawar lubrication a cikin sauri mai girma, yana shafar zaman lafiyar su da rayuwar sabis, kuma ba su dace da aikace-aikacen aiki mai sauri ba.
5. Jijjiga da amo: A lokacin aiki na zamewa bearings, vibration da amo suna da sauƙin haifar saboda kasancewar gogayya, wanda ya kara rinjayar da kwanciyar hankali na kayan aiki da kuma yanayin aiki.
6. Wahala wajen gyarawa da gyarawa: Tsarin ɗorawa na zamiya yana da rikitarwa kuma yawanci yana buƙatar kulawa da gyarawa, wanda ke ɗaukar lokaci mai yawa da farashin aiki.
A taƙaice, manyan lahani na ɗigon zamewa sun haɗa da juzu'i da lalacewa, babban buƙatun lubrication, wahala a cikin samar da zafi da tarwatsewa, rashin dacewa da aiki mai sauri, girgizawa da amo, da kuma matsalolin kulawa da gyarawa.
Babban fa'idodin rolling bearings sune:
1. Ƙarƙashin amfani da makamashi, yin amfani da na'ura mai juyayi maimakon zamewa bearings yana rage yawan kuzarin injin ƙwallon da kusan 10%.
2. Sauƙi don kwancewa. Yin amfani da ƙirar mazugi na musamman, shigarwa yana da sauƙi musamman, yana guje wa aikin gogewa da niƙa na birgima, yana mai sauƙin kiyayewa.
3. Rayuwa mai tsawo. Saboda gaskiyar cewa zaɓin bearings akan ƙwalƙwalwar ƙwallon ƙafa zai iya dogara ne akan ƙarfin sarrafawa ko ƙarfin fitarwar tama, abubuwan da aka zaɓa sun zarce ƙarfin ɗaukar nauyin da aka tsara. Sabili da haka, rayuwar sabis na mirgina bearings a kan ƙwallon ƙwallon ƙafa sau da yawa ya fi tsayi fiye da na ƙwallon ƙwallon ƙafa, kuma aikin su yana da kyau.
4. Hanyar lubricating yana da sauƙi, kuma ana yin amfani da ƙwanƙwasa na mirgina tare da man shafawa, wanda kawai yana buƙatar ƙarawa akai-akai, yana tabbatar da abin dogara.
Sabili da haka, yin amfani da birgima a cikin injin ball yana da fa'idodin tattalin arziki mai kyau. Ba wai kawai yana da ƙarancin juriya ba, ƙarancin amfani da makamashi, ƙarancin aiki na yanzu, barga mai farawa, amma kuma yana da tasirin ceton makamashi mai mahimmanci, yana rage wuraren tallafi, da adana farashi.
