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.
