The Gears are located in the Gearbox. These provide the movement of the mechanism.
Gears are available in different types..
High Torque: High torque gears have a higher torque. This results in less power needed for the motor to pull the spring, at a cost of speed. This makes the system more efficient in its powerconsumption. Extreme High Torque gears often need special Half Teeth Pistons.
High Speed: High speed gears can achieve a high rate of fire. They are ment to achieve high revolutions, at costs of torque. These are often only suited for less powerfull springs.
Helical: Helical gears have angled teeth. This enables a larger contact surface. In general, this ensures a lower soundproduction. They are better suited for high speed and high power transfers. Shimming is very important with these gears.
