The AndyMark Flyer Overdrive Gearbox, CIM/NEO Input, 2:50:1 / 1:2.50 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, thanks to the standardized 1.125 inch outer diameter of both the front and rear bearings. This flexibility allows for the installation 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.
The design of the gearbox incorporates “wings” that facilitate easy mounting onto any 1 inch wide extrusion, such as Peanut or Box Tube, simplifying integration into a robot’s frame. The gearbox supports three hardware options for input: CIM/NEO, Falcon, and Sport Gearbox. The CIM/NEO and Falcon 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 a secure mounting solution, which is beneficial for mechanisms like climbers.
Additionally, the gearbox can be purchased without gears, allowing users to supply their own gears to achieve custom ratios. It accommodates any two 20DP gears with a 1/2 inch hex bore that total 70 teeth. This flexibility extends to using the gearbox as a mounting point for an extended shaft in a symmetrical setup.
