Description

  • AndyMark EVO Shifter Short Keyed Shaft, StageA 2 - 04.77:1 Ratio, StageB 2 - 06.00:1 Ratio
  • Advances seamless two-speed shifting
  • Allows CIM or NEO motor compatibility
  • Incorporates robust AMPCO® 18 Bronze gears
  • Offers flexible staging and mounting options
  • Enhances encoder choices and weight reduction

The AndyMark EVO Shifter Short Keyed Shaft, StageA 2 - 04.77:1 Ratio, StageB 2 - 06.00:1 Ratio represents a significant advancement in shifting transmission gearboxes. This two-speed, shift-on-the-fly gearbox incorporates an enhanced 4-tooth dog shifting mechanism, allowing for seamless transitions between speeds. It is compatible with two CIM or NEO motors and can be configured with either two or three interior stages, offering flexibility in output shaft selection.

The EVO Shifter features several improvements over previous models, including a robust 1/8" diameter shoulder screw and a dog gear made from AMPCO® 18 Bronze, which provides added lubricity for smoother operation. The gearbox's input stage utilizes 32 DP gears and a 15-tooth pinion gear, achieving a high 85:15 first stage reduction. Users can independently select high and low ratios, with the ability to swap between them as needed. Additionally, the gearbox offers more encoder options, including the US Digital E4T and the CTRE SRX mag encoder.

The design incorporates aggressive weight reduction features and allows for easy assembly and disassembly due to the uniform features of the cluster gears. An optional third stage provides additional ratio choices, and the gearbox can be mounted to an AM14U family chassis or a 2"x1" box tube frame. The pneumatic shift method, powered by a spring-extend pneumatic cylinder, enables shifting while a robot is in motion.

The gearbox requires proper greasing for optimal performance and longevity. It is recommended to run the gearbox for a short period without grease to allow the gear teeth to wear in before applying grease. The gearbox is shipped assembled but without motors, even if motors are included in the order. Note: Ensure proper installation of the pinion gear using the recommended procedures to avoid operational issues.
