The AndyMark Flyer Overdrive Gearbox, Sport Gearbox Input, 1.92:1 / 1:1.92 is an innovative gearbox designed for the FIRST Robotics Competition (FRC), offering both overdrive and underdrive capabilities within a single unit. This versatility allows the output shaft to spin faster or slower than the input, 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. The design accommodates a pass-through shaft by replacing the rear bearing with another 1/2 inch hex bearing, allowing for customization without machining. This feature is particularly useful for creating a roller intake when combined with compatible wheels.
Mounting the gearbox is straightforward, thanks to its 'wings' that fit over any 1-inch wide extrusion, such as Peanut or Box Tube, facilitating easy attachment to a robot's frame. The gearbox supports three hardware input options: CIM/NEO, Falcon, and Sport Gearbox. The Sport Gearbox option provides an additional stage of reduction and secure mounting, making it suitable for applications like climbers. It is important to note that these options modify the hardware included with the Flyer but do not come with a motor or planetary gearbox.
For those who prefer to use their own gears, the gearbox offers a no-gears option. It can accommodate any two 20DP, 1/2 inch wide, 1/2 inch hex bore gears totaling 70 teeth. This flexibility allows users to achieve a custom ratio not currently offered. Additionally, the empty shell can serve as a mounting point for the other end of an extended shaft, enabling a symmetrical setup.
