Product Overview

This shift-on-the-fly gearbox, uses a dog gear shifting method. Motor input accepts two CIM style motors. The output shaft is a round 1/2" 4140 steel shaft with a 1/8" keyway.

The Super Shifter includes hardware for pneumatic shifting, but the pneumatic cylinder is not included.

Three differences compared to the original AM Shifter design:

  • An extra reduction stage is included. This stage allows for direct drive applications of 4", 6" and 8" wheels.
  • The output shaft extends outside the gearbox, as opposed to being captured within the side plates.

Shift Style:

  • Pneumatic:
    • A pneumatic cylinder, Bimba model 04-0.5-DP, 3/4" bore x 1/2" stroke, (not included) shifts between high and low gear. This cylinder mounts with a 5/8-18 nut (not included). This is a strong, fast method of shifting, lasting under 0.5 seconds and pushing with 26 pounds of force (if using 60 psi). This pneumatic shift can be done while a robot is accelerating.

Total Weight: approx. 4.0 lbs., without motors or pneumatic cylinder installed

Product Usage:
All AndyMark gearboxes require grease for proper operation and long life. We suggest using our red tacky grease, am-2768. We also encourage that the user powers the gearbox continuously for 30 minutes without grease to allow the gear teeth to wear in. While we do design with short run times in mind, this 'run in' period for smooth gearbox operation, is recommended. Once this is completed, thoroughly grease the gear teeth periodically to ensure smooth operation.
