Haddaba, waa maxay garoonka silsiladda rullaluistuyada?Erayada fudud, garoonku waa masaafada u dhaxaysa saddexdii rullale ee isku xiga.Waa cabbirka ugu muhiimsan ee silsiladaha rullaluistuliga ah maadaama ay go'aaminayso iswaafajinta silsiladda xadhkaha.Fahamka fikradda garoonku waa muhiim marka la dooranayo silsiladda rullaluistemadka saxda ah ee codsi gaar ah.
Si aad u hesho faham dareen leh, qiyaas silsilad rollaalooyin ah oo lagu fidiyay xariiq toosan.Hadda, cabbir masaafada u dhaxaysa xarumaha saddexdii biin oo isku xigta.Cabirkan waxaa loo yaqaan ' pitch'.Silsiladaha rullaluistu waxay ku jiraan cabbirro garoon oo kala duwan, mid walbana wuxuu leeyahay ujeedo gaar ah.
Baaxadda garoonka silsiladda rullaluistu waxay saamaysaa guud ahaan xooggeeda, culayska qaadida iyo xawaaraha.Guud ahaan, cabbirrada garoonnada waaweyn ayaa loo adeegsadaa codsiyada warshadaha culus, halka cabbirrada garoonnada yaryarna caadi ahaan loo isticmaalo codsiyo yar yar.Cabbirka garoonku wuxuu sidoo kale go'aamiyaa astaanta iliga ee sprocket-ka, taas oo muhiim u ah hubinta isku-waafajinta silsiladda iyo sprocket-ka.
Si loo go'aamiyo cabbirka silsiladda rullaluistuyada habboon ee codsiga, dhawr arrimood ayaa loo baahan yahay in la tixgeliyo.Kuwaas waxaa ka mid ah awoodda culeyska loo baahan yahay, awoodda la isugu gudbiyo, xawaaraha loo baahan yahay iyo guud ahaan jawiga shaqada.Soo-saareyaashu waxay bixiyaan tilmaamo faahfaahsan iyo jaantusyo si ay uga caawiyaan doorashada cabbirka silsiladda rullaluistuyada saxda ah ee codsiga la bixiyay.
Waxaa habboon in la sheego in garoonnada silsiladda rullaluistu ay tahay mid jaangooyo ah, iyada oo la hubinayo is-waafajinta ka dhexeeya soo saarayaasha kala duwan.Cabbirrada silsiladda rullaluleyda ee ugu caansan waxaa ka mid ah #25, #35, #40, #50, #60, #80, iyo #100.Tirooyinkani waxay muujinayaan cabbirka garoonku siddeed meelood meel meel inch ah.Tusaale ahaan, silsiladda #40 rullaluistu waxay leedahay cabbir garoon oo ah 40/8 ama 1/2 inch.
Iyadoo cabbirka garoonku uu yahay tixgelin muhiim ah, garoonnada silsiladda rullaluistu waxay sidoo kale ku lug leedahay tirada isku xirka halbeeg kasta oo cabbir ah.Habkani wuxuu go'aamin karaa dhererka silsiladda looga baahan yahay codsi gaar ah.Tusaale ahaan, silsilad 50-pitch ah oo leh 100 xiriiriye waxay noqon doontaa laba jeer inta ay le'eg tahay silsiladda 50-pitch oo leh 50 xiriiriye, iyada oo loo maleynayo in dhammaan cabbirada kale ay yihiin kuwo joogto ah.
Marka la soo koobo, marka lagu shaqeynayo silsiladaha rullaluistuyada, waxaa lama huraan ah in la ogaado heerka silsiladda rullaluistuyada.Waxay tilmaamaysaa masaafada u dhaxaysa saddex kasta oo xidhiidhin ah oo isku xigta waxayna go'aaminaysaa la jaanqaadka sprocket-ka.Cabbirka xajmigu wuxuu saameeyaa xoogga silsiladda, awoodda qaadida iyo xawaaraha.Doorashada cabbirka saxda ah ee garoonka ayaa muhiim u ah waxqabadka ugu wanaagsan iyo nolosha adeegga silsiladdaada rullaluistemadka.Had iyo jeer tixraac tilmaamaha soo saaraha iyo jaantusyada si aad u dooratid cabbirka silsiladda rullaluistuyada habboon ee codsi gaar ah.Iyada oo cabbirka saxda ah ee saxda ah, silsiladaha rullaluistu waxay bixin karaan gudbinta awood la isku halayn karo ee warshado kala duwan.
