Objectives & Priorities
• Made out of a A4 sheet of acrylic• Able to drag a load of 10kg up ramp• All components are laser cut• Gearbox compatible with mounting
plate• As compact as possible• Simple setup and quick operation
• High load capacity• Greater teeth strength• High contact ratio• Smoother operation
o Difficult to laser cut
Helical Gears
Planetary Gears
• Compact gearing ratio to volume efficiency• Distribution of Torque• High gearing ratios
o Complex system designso Gearing has to be accurateo High complexity has room for more errors
Spur Gears
• Simple to manufacture• Easy installation• Constant velocity ratios• Compound gear system is compact
o High stress on gear teetho Loud at high speed operations
Friction Reduction
Roller Bearings• Bearings require precision to manufacture of
which can be problem with laser cutting curved surfaces.
• Bearings introduces more surface area, from which power can be loss.
Lubrication (Silicone grease)• Silicone grease is considered a good
lubricant for most plastics.• Doesn’t damage the acrylic• Easy to acquire, can be bought at the local
hardware store.
