Trampa Open Drive with TB 6380 - motor shaft too short

[sebastian]

Hi Forum,

I am about to assemble a Prototipo with Trampa Open Belt System and my TB 6380 Motors.
looks like my shaft is almost a cm too short.
The shaft sticks 35mm out of the motor can though while Trampa’s motors are 38.5. I would have thought the difference is not so much but If i want to align the pulley with the belt tension wheel then it’s 1cm missing.
Seems all assembled correct though. Do I need to replace the shaft?

Grateful for any input. Thanks

Get a keyed pulley with a set screw in the middle

Flip your pulley so that the teeth are the furthest part from the motor. That should buy you some mm’s

[sebastian]

thanks, that would kinda work, just hope the thing doesn’t fall off or gets deformed from the belt force. I suppose will be steel pulley only as the shaft is only to thirds though.

I would do this, too. I hate collared pulleys for this reason.

I’ve gotten away with worse.
