Planetary transmission

An ice drill, the ice drill comprising:

• a power head, the power head configured to allow the user to control operation of the ice drill;
• an engine, the engine producing a right-handed output rotation at a crankshaft;
• a planetary transmission, the planetary transmission including:
• a pinion gear, the pinion gear:
• connected to the output rotation of the engine;
• and
• receiving the output rotation from the crankshaft;
• a set of planetary gears, the planetary gears each in operational contact with the pinion gear;
• a gear bracket, the gear bracket maintaining the position of the planetary gears relative to the pinion gear;
• a ring gear, the ring gear including inward facing teeth that are in operational contact with each of the planetary gears in the set of planetary gears such that:
• the rotation speed has been changed by a specified ratio;
• and
• the rotation has been changed to left-handed in orientation;
• and
• an output shaft connected to the ring gear;
• an auger, the auger attached to the output shaft;
• and
• a cutting blade, the cutting blade configured to be moved by the auger to create a hole in ice.
