 FIRST is aimed at those girls on your team. They don't know anything about mechanics, or electricity, or programming, or machining. They have no interest in it, either. They're perfect candidates for FIRST. - Madison [more] |

Re: pic: Shaft Drive Bearing Blocks
Matt,
I know that the drawing may not show the components in correct scale but with this kind of drive there are some significant forces that need to be addressed. The rotational forces on each shaft when pushing or in stall will produce a side force if you think about it. Because of those forces, larger bearings and stiffer blocks are needed relative to other types of drive. Without the extra beef, misalignment and high frictional forces will occur in the bearings and shafts. Think of the construction of a car differential and you will get an idea of the kind of strength you will need.
