The AndyMark EVO Shifter Short Hex Shaft, StageA 3 – 08.63:1 Ratio 1.14:1, StageB 3 – 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 mechanism, allowing for smooth and efficient 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 performance. The gearbox is shipped assembled, though motors are not included.
The design improvements include a robust 1/8″ diameter shoulder screw and the use of AMPCO 18 Bronze for the dog gear, which provides added strength and lubricity compared to previous materials. The gearbox features a super-strong shift block assembly with a larger bearing and threaded steel housing, enhancing durability. The input stage utilizes 32 DP gears with a 15-tooth pinion gear, enabling a high first stage reduction. Users can independently select high and low ratios, and the gearbox supports various encoder options, including the US Digital E4T.
The EVO Shifter employs a pneumatic shift method, powered by a spring-extend pneumatic cylinder, which allows shifting while a robot is in motion. The gearbox is designed with aggressive weight reduction features, and its components are engineered for easy assembly and disassembly without concern for gear orientation. It can be mounted to an AM14U family chassis or a 2″x1″ box tube frame, providing versatility in application.
Note: Ensure proper greasing and break-in procedures are followed for optimal performance and longevity of the gearbox.
