Chatter Gear Box

thingiverse

A quick and dirty hack on MakerBlock's chattering teeth gears was performed, with the MCAD version of the involute_gear library used. The gear_box() module replicates gears based on an input 'stages', with each stage adding a factor of 4 to the total gear ratio. By adjusting n1 and n2, the unitary gear ratio can be changed. However, regenerating all three types of gears is necessary if these parameters are modified. The mechanism's design requires incorporating the stack into the original spring drive. If running a shaft where the spring-gear is not possible, rotating the spring gear out of the way may be necessary, but it will make the mechanism less compact.
