Retaining Rings Sticking Outisde of Frame
My team had a question about the frame perimeter rules, we have a few roller shafts sticking outside our frame perimeter about a 10th of an inch with a retaining ring and was wondering if this is legal.
According to the rules: R01. The ROBOT (excluding BUMPERS) must have a FRAME PERIMETER, contained within the BUMPER ZONE, that is comprised of fixed, non-articulated structural elements of the ROBOT. Minor protrusions no greater than ¼ in. (~6.3 mm) such as bolt heads, fastener ends, weld beads, and rivets are not considered part of the FRAME PERIMETER. TL;DR are retaining clips considered a fasteners? Thanks! |

The purpose of a retaining ring is to keep a shaft from leaving a designate location, therefore one could easily argue that it FASTENS the shaft in place.

I would probably see it as a minor protrusion if I were inspecting you. Would probably need to see it in person to be more sure.

Nolan,
An inspector would have to see to make a ruling but in my experience, a clip on a shaft is usually pushing against a bearing. Most such assemblies will end up being more than 0.10" beyond the frame. In any case, the end of the shaft is the protrusion. |
