The AndyMark EVO Slim 16.37:1 Ratio, ~2in Shaft Length is a high-performance, lightweight gearbox designed to enhance the drive trains of competition robots. This single-speed gearbox is part of the EVO Slim line, which shares several components with the EVO Shifter, including weight-relieving features and robust construction with all-steel gears and aluminum plates. It is provided in kit form, allowing for customization and assembly to accommodate up to three motors, although motors are not included.
The gearbox utilizes a 15 Tooth 32DP pinion gear, which is included and does not require a key. For those who prefer not to install the pinion themselves, motors with pre-installed pinions are available. The installation process for the pinion varies depending on the motor type. For a NEO motor, a 3-ton arbor press is necessary due to the interference fit, while for a CIM motor, the fit may be either slip or press, depending on manufacturing tolerances. In both cases, the application of red Loctite 271 is recommended to ensure secure attachment.
The EVO Slim gearbox is compatible with either the E4T Optical Encoder Kit or the SRX Mag Encoder, requiring a 3D printed mount plate for installation. Future versions will include appropriate holes in the motor plates to accommodate the Encoder Mount Pad. When using the SRX Mag Encoder, additional mounting hardware is necessary to ensure proper installation.
Note: Ensure proper safety measures are followed when installing pinions and encoders to prevent injury or damage.
