The AndyMark EVO Shifter am14u Family Shaft, StageA 3 Stage - 18.71:1 Ratio 1.14:1, StageB 3 Stage - 12.41:1 Ratio 1.14:1 represents a significant advancement in shifting transmission gearboxes. This two-speed, shift-on-the-fly gearbox incorporates an enhanced 4-tooth dog shifting method, 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.

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 increased strength and smooth shifting due to its lubricity. The shift block assembly has been reinforced with a larger bearing and threaded steel housing. The input stage utilizes 32 DP gears and a 15-tooth pinion gear, achieving a high first stage reduction of 85:15. Users can independently select high and low gear ratios, and the gearbox supports easy disassembly and reassembly without concern for gear orientation.

The gearbox employs a pneumatic shift method, utilizing a spring-extend pneumatic cylinder for shifting, which can be executed while a robot is in motion. The design includes aggressive weight reduction features and can be mounted to an AM14U family chassis or a 2"x1" box tube frame. Additional encoder options are available, enhancing its adaptability for various applications.

Note: Ensure proper greasing and break-in procedures are followed for optimal performance and longevity of the gearbox.
