Description

  • AndyMark EVO Shifter am14u Family Hex Shaft, StageA 2 Stage - 06.00:1 Ratio, StageB 2 Stage - 22.67:1 Ratio
  • Advances shifting with a 4-tooth dog mechanism
  • Supports two CIM or NEO motors
  • Offers flexible two or three interior stages
  • Enhances durability with AMPCO® 18 Bronze
  • Integrates pneumatic shift-on-the-fly feature

The AndyMark EVO Shifter am14u Family Hex Shaft, StageA 2 Stage - 06.00:1 Ratio, StageB 2 Stage - 22.67:1 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 gears. 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 gearbox is delivered assembled, though motors are not pre-installed.

Several improvements distinguish this model from previous iterations. The dog gear now features four dogs on each face, enhancing the strength and durability of the design. The use of AMPCO® 18 Bronze for the dog gear material provides added lubricity, ensuring smooth shifting operations. A robust shift block assembly with a larger bearing and threaded steel housing further enhances the gearbox's reliability. The input stage employs 32 DP gears and a 15-tooth pinion gear, facilitating a high first stage reduction of 85:15. Users have the liberty to independently select high and low ratios, with the option to swap ratios as needed.

The gearbox also supports a variety of encoder options, including the US Digital E4T and the CTRE SRX mag encoder. Weight reduction features have been meticulously integrated into the gears and plates, and the cluster gears are designed for easy assembly and disassembly without concern for gear orientation. 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 using existing mounting plate holes.

The EVO Shifter employs a pneumatic shift method, utilizing a spring-extend pneumatic cylinder that allows shifting while a robot is in motion. This ensures continued operation even if air pressure is lost, as the cylinder defaults to the selected "Ratio A". The gearbox requires proper greasing for optimal performance and longevity, with a recommended break-in period before applying grease to the spur gears.
