The AndyMark Flyer Overdrive Gearbox, Falcon 500 Input, 1.33:1 / 1:1.33 is an innovative gearbox designed for competitive robotics applications, particularly in the FIRST Robotics Competition (FRC). This gearbox is distinguished by its dual functionality, allowing it to operate as both an overdrive and an underdrive system. This versatility is achieved through its unique design, which permits the output shaft to spin faster or slower than the input shaft, depending on the configuration chosen by the user. The gearbox features a 1/2 inch hex bore on both gears, enabling easy selection between the two available ratios without the need for additional purchases.
The gearbox includes a short 1/2 inch hex output shaft that extends approximately 2 inches from either face of the gearbox. Users have the option to replace this with any Toughbox Output Shaft, providing flexibility in customization. The design also allows for the replacement of the rear bearing with another 1/2 inch hex bearing, facilitating the use of a pass-through shaft of any desired length without requiring machining. This feature makes it particularly suitable for applications such as roller intakes 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, simplifying integration into a robot's frame. The gearbox offers three hardware options for input: CIM/NEO, Falcon, and Sport Gearbox. The first two options are ideal for flywheel shooters, providing a bearing-supported output shaft optimized for absorbing shock loads. The Sport Gearbox option offers an additional stage of reduction and secure mounting, making it suitable for mechanisms like climbers.
For those who prefer to customize further, a no gears option is available, allowing users to supply their own gears to achieve a specific ratio not currently offered. The gearbox can accommodate any two 20DP, 1/2 inch wide, 1/2 inch hex bore gears totaling 70 teeth, or serve as a mounting point for an extended shaft in a symmetrical setup.
