## Gearbox Ratio Calculator - Technobots Online

Stages not selected will be ignored in the overall ratio calculation 5 If 2 or more stages are required, the driven gear of the preceeding stage needs to be fixed on the same shaft as the drive gear of the next stage This shaft is commonly called a lay shaft and should be supported on its own bearing mountsDESIGN OF TWO STAGE PLANETARY GEAR TRAIN FOR HIGH ,In conventional helical gear system, the ratio 78: 1 requires three stage reductions which become bulky Hence authors had identified problem as ―Design of two stage planetary gear trains for reduction ratio 78: 1‖ and the objective of study are as underOther Uses for Gears - How Gear Ratios Work - Science,One way to create that ratio is with the following three-gear train: In this train, the blue gear has six times the diameter of the yellow gear (giving a 6:1 ratio) The size of the red gear is not important because it is just there to reverse the direction of rotation so that the blue and yellow gears turn the same way
