The AndyMark Flyer Overdrive Gearbox, CIM/NEO Input, 2.89:1/1:2.89 is an innovative gearbox designed for competitive robotics, particularly in the context of 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, thanks to the standardized 1.125 inch outer diameter of both the front and rear bearings. This flexibility allows for the use of a pass-through shaft of any desired length, secured with collar clamps and supported at the end, making it suitable for applications such as roller intakes when combined with compatible wheels.
Mounting the gearbox is straightforward due to its "wings," which are designed to 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 CIM/NEO and Falcon options are ideal for flywheel shooters, providing a well-supported output shaft optimized for absorbing shock loads. The Sport Gearbox option offers an additional stage of reduction and secure mounting, with the possibility of a reversed, offset shaft, making it suitable for mechanisms like climbers.
For those who prefer to customize their gear ratios, the gearbox is available 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.
