Planetary Gear Train Modelling
MIE341 Mechanical Engineering Design February 2015 In our design laboratories, we dissected a handheld electric screwdriver to examine it's planetary gear train. The parts were first measured to determine it's dimensions, and then modelled using Solidworks. Gear theory and calculations were applied to ensure accurate modeling of the mechanism motion. Concepts such as involute profiles and pitch diameters were required for the meshing of gears to achieve the desired ratio of 1:30 |
