The AndyMark Flyer Overdrive Gearbox, CIM/NEO Input, 1.33:1/1:1.33 is an innovative gearbox designed for use in competitive robotics, particularly in the FIRST Robotics Competition (FRC). This gearbox is unique in its ability to function both as an overdrive and an underdrive system, allowing the output shaft to spin faster or slower than the input shaft, respectively. This dual functionality is achieved through the use of gears with a 1/2 inch hex bore, enabling users to configure the gearbox according to their specific needs without requiring additional purchases.
The gearbox features a short 1/2 inch hex output shaft that extends approximately 2 inches from either face of the gearbox. Users have the flexibility to replace this with any Toughbox output shaft, and the design accommodates a pass-through shaft setup without the need for machining. This adaptability makes it suitable for various applications, such as creating a roller intake when combined with compatible wheels.
Mounting the gearbox is straightforward, thanks to its "wings" that are designed to fit over any 1-inch wide extrusion, such as Peanut or Box Tube, facilitating easy integration into a robot's frame. The gearbox supports multiple input hardware options, including CIM/NEO, Falcon, and Sport Gearbox. The CIM/NEO and Falcon options are particularly effective for flywheel shooters, providing a robust bearing-supported output shaft that can handle the shock loads associated with high-speed wheel contact. The Sport Gearbox option offers an additional stage of reduction and a secure mounting solution, ideal for mechanisms like climbers.
For those who prefer to customize their gear ratios, the gearbox can be purchased without gears, allowing the use of any two 20DP, 1/2 inch wide, 1/2 inch hex bore gears totaling 70 teeth. This flexibility extends to using the gearbox shell as a mounting point for an extended shaft, enabling symmetrical setups.
