Snubbers used in shear
« on: August 03, 2018, 01:34:17 pm »
I am curious about the use of snubbers to isolate different modules of a bot.  For example, bombshell and war hawk use many snubbers in the horizontal plane to isolate the main pod from the side pods of the bot.  It seems to work really well.  But it conflicts with the accepted explanation of snubbers, which is that they are great axially but horrible in shear.  For example, if you look at mcmaster, the shear rating is about 1/5 of the axial rating.

If these bots took a vertical spinner hit it seems like the snubbers would shear off.  Is it just that there are so many of them being used that they can share the load enough to survive?  Is there something else going on that I am missing?   Thanks!
