Title: Some questions reguarding a specific gearmotor, wheels and stuff
Post by: vagoir on December 03, 2009, 07:23:08 AM
Greetings,
this is my first post to this wonderful site :)

so my problem is that i recently bought this gearmotor: http://www.robot-italy.com/product_info.php?cPath=8_90&products_id=483 (http://www.robot-italy.com/product_info.php?cPath=8_90&products_id=483) but i have no idea how I can attach a wheel to it...what parts do I need? and also what parts do i need to mount the motor to the robot chasis.
I'm an electronix student but this is the first time i try to build a robot.

thank you for you help :)

You need a wheel or hub with a 4mm hole and set screw to lock onto the motor shaft.
Here is a hub:

and wheels:

That looks to be a nice motor. Wonder if they ship to the USA?

The hub should just slide onto the gear motor shaft and then locked on by tightening the set (grub) screw.

You will need the drill hole in the wheel to match the hole pattern on the hub. Then use the long screws that come with the hub to bolt the wheel and hub together.
