Product Overview

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.

Weight Reduction with Optional Parts sold separately: Additional Encoder:
An optional Encoder Package can be purchased and added to this Toughbox. If you already have a US Digital Encoder to fit this Toughbox, this Encoder Mount Pad will help you mount the encoder to the Toughbox. A very complete guide for encoder installation and alignment is shown on the Encoder Package page.

Motor Mount Plate Options:
We offer a Standard mount plate made out of polycarbonate.

Optional Long Output Shaft:
T-Box Long Output Shaft is available, which is 3.5 inches longer than the standard Output Shaft.

Aluminum Hex Output Shafts:
The Toughbox can use a hex aluminum output shaft, but a FR8ZZ-Hex bearing must be ordered to replace the FR8ZZ bearing supporting the output shaft.

    Marginal design plagued by fit and finish issues

    I have ordered five of these gearboxes and none of them have left me feeling warm and fuzzy inside. Fit and finish has been a recurring issue. Several of the gears simply didn't fit on shafts or shafts didn't fit into the bearings. Some file time on a lathe to make excessive chamfers and actually turning some of the shaft OD's down has helped, but this should not be necessary. This is not even touching on the inherently bad design of the gearbox. Transparent plastic is great for visibility, but makes for a terrible bearing support plate. These things are LOUD, no matter how much monkeying is done. Considering the primarily educational context of these products, these drawbacks may be considered good? I guess it's a good education in things to not do in product design. Regardless, they've worked and haven't hand grenaded yet.

    14:1 My Favorite Ratio

    The standard 12:1 ratio works great, but the 14:1 ratio really gives an edge in acceleration and pushing force. I know, I know "it slows you down", but how long do you ever spend a peak velocity? Not nearly as much time as you do speeding up and slowing down. We did the math and 14:1 is my favorite ratio.

    Problem with gear

    The gears do not fit the acrylic plate. To fit the engine has to be tilted and complying engage a little get stuck. I can not therefore connect more than one motor. For the project I'm doing I need two motors in the transmission. I need this transmission as fast as possible.
