Re: Difference Between Dog Shifting and Ball Shifting

A dog shifter uses a dog gear to shift.
A pneumatic cylinder pushes this gear into corresponding slots on the actual output gears and when it engages the force is transferred through it into the output shaft. When not engaged the output gears just spin on bearings. I would take a look at wcp's dog shifter CAD to see exactly how this works. Ball shifters work similarly, however they use 3 ball bearings and a plunger instead of a dog. I personally would design a dog shifter first as, at least for me, is simpler to understand and fix.
