Printed Truck: Gearbox Helical 18:1 Ratio

cults3d

I will work with Truck V1 and Truck V2. Simple gearbox with helical gears is perfect for 540 brushed motors. Print, add some grease, and it works great! Here are the hardware you need: 4mm axles 4mm bearings - I used 624zz bearings. M3 grubscrews for locking the gears You can see more videos of the V1 and V2 truck over at my youtube channel: http://www.youtube.com/c/MrCrankyfaceProjects. Edit 2016-03-12: Added bighelical32t_0.7m_PIN.stl, this is the output gear with a 1.5mm hole for putting a pin through the gearshaft - it works better than just using grub screws but requires drilling through the metal shaft. Edit 2016-03-27: Updated with new gearbox housing that'll work in both Truck V1 and Truck V2. Edit 2016-04-23: Apparently, the new gearbox housing had some tight tolerances around the gear - so I made some more space there. Only one file changed is mount2.stl. Also added spacer.stl which helps align the gears - put it behind the big middle gear.
