Re: Engaging Gears Perpendicular to Shaft Direction?
There is no reason why this type of shifter wouldn't work(referring to the original drawing). There are a few problems to overcome so it comes down to a matter of pros and cons. The cons being the majority here, lets just list those. The transmission is not very compact, requires precise engagement of the teeth at speed or load, requires firm! locking of the driven shaft in place to constantly mesh with the driving shaft, requires a more complex and weighty shifting mechanism and if any of the above fails or is intermittant, the result is catastrophic. The result is many teams use an alternative that minimizes the cons and maximizes the pros. The last robot standing is not necessarily the better robot, just the last one standing.
