Page 2 of 10 Gear Fundamentals:
At the most fundamental level, gears provide a way to modify circular motion. Gear trains can be used to change the direction of circular motion, alter its speed and torque, or completely translate circular to linear motion. In the AEG mechbox, all three of these capabilities are used. There are several different types of gears, four of which are present in a typical AEG mechbox: the bevel gear, the standard/spur gear, the sector gear, and the rack gear. Bevel gears are typically used to change the direction of motion, a trait necessary in the AEG mechbox to turn the motor output shaft motion 90 degrees. Standard or spur gears can be used in a variety of roles, but serves mainly as the torque multiplier in the AEG mechbox. Sector gears feature teeth on only a partial sector of the gear circumference, and is typically used when constant gear meshing is not desirable. Lastly, the AEG piston serves as a rack gear to translate the circular motion of the gear train into linear motion to compress the main spring.
