-Shock Loading How important is it?

[Patrick Wang]

Looking at the Technokats gearbox, and working on a gearbox of my own, I noticed that there were accomodations made for "shock loading" the system with a Flexible coupling.

My question is, how necesary is this to a geartrain design (we have always run with chains and sprokets before and have not encountered any need to shock load the system.) to shock load the system. Would for example an impact of a robot running into a wall or another robot pose a risk factor to a geartrain that was not shockloaded?

Thanks in advance for anyone who still reads the boards over the summer
