Description
- AndyMark EVO Shifter am14u Family Hex Shaft, StageA 3 Stage – 08.63:1 Ratio 1.14:1, StageB 3 Stage – 06.86:1 Ratio 1.14:1
- Features two-speed shifting on-the-fly
- Accommodates two CIM or NEO motors
- Utilizes robust AMPCO 18 Bronze dog gear
- Optimized for easy assembly and disassembly
- Employs spring-extend pneumatic cylinder
The AndyMark EVO Shifter am14u Family Hex Shaft, StageA 3 Stage – 08.63:1 Ratio 1.14:1, StageB 3 Stage – 06.86:1 Ratio 1.14:1 represents a significant advancement in shifting transmission gearboxes. This two-speed, shift-on-the-fly gearbox is designed with an improved 4-tooth dog shifting method, allowing for seamless transitions between speeds. It accommodates motor input from 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 installed, even if included in the order.
The EVO Shifter incorporates several enhancements 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 shifting. The shift block assembly is reinforced with a larger bearing and threaded steel housing, ensuring durability. The input stage utilizes 32 DP gears and a 15-tooth pinion gear, achieving a high first stage reduction of 85:15. Users have the liberty to select independent high and low ratios, with the option to swap ratios as needed. Additional encoder options are available, enhancing the gearbox’s adaptability.
The gearbox features aggressive weight reduction techniques and is designed 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 using existing mounting plate holes. The pneumatic shift method employs a spring-extend pneumatic cylinder, allowing shifts to occur even during acceleration or deceleration. The gearbox’s weight ranges from 2.9 to 3.5 pounds, depending on the stage configuration.
Note: Proper greasing is essential for optimal operation and longevity of the gearbox. It is recommended to run the gearbox for 30 minutes without grease for a break-in period before applying grease to the spur gears periodically.
