Mounting VEX VersaPlanetary 100:1 Gearbox

[Dr.Gusta]

We have a VEX VersaPlanetary 100:1 gearbox and it powers our arm up and down. We got our belt and everything else but once we fired it up our mount got annihilated. I have attached a picture of the mount's CAD below. It is a 1/16in alum plate sandwiched in between the motors and the gears then stood off with churros. How has everyone else been mounting their gearboxes? Post pictures please? Thank you so much.

What part exactly is getting broken? Im going to take a guess and say its the alu. plate. I would say if at all possible put it in double sheer and support the pulley on the other side to take a lot of the angular load off of it.

Why are you using that plate in addition to the face mounts on the versaplanetary? The face mounts are plenty enough to hold that gearbox on, and that plate could be causing internal problems in the gearbox because of spacing.

We too have the 100/1 to power our arm rotation. We attached it using the vex corner gusset, with some reinforcement in the frame. We are also going to install an axle coupling to add a second corner gusset about 4" along to prevent moment.

1/16 in. plate is very thin. You may want to consider beefing it up or consider switching to steel.

Also, like the other posts say, consider face mounting the VersaPlanetary instead of using the churro mount. That way you'll spread the load on the face of the motor and eliminate the bending moment and shear stresses on the churros and the aluminium plate.

The torque imparted by the winch on the gearbox is causing the mount to break.

I would use the face mount holes and then if that wasn't enough add angled brackets up to the side mounting holes on the VP. The Versa Planetary isn't designed to be mounted to from the back and you don't really have anyway to react against the torque effectively.
