ToughBox Micro S

The ToughBox Micro, a lightweight single-speed gearbox great for mecanum drive trains and more, has improved! Say hello to the ToughBox Micro, now, with an S.

The features everyone needs are here to stay; the drop-in option for the AM14U drive bases accept NEO and CIM-style Motors. "What has changed?", you ask. For starters, gears are now symmetrical. No longer, will you need to ensure gears are installed in the correct orientation! Secondarily, pocketed gears are now an off-the-shelf option for you to choose when saving weight is a priority. If you have gear stock on hand and you want to save money, you can now order with output gears excluded. 

Like many gearboxes we offer, the ToughBox Micro S can be ordered with your plate, ratio, and shaft of choice based on your needs.  If you want the ToughBox Micro as it was, now called the ToughBox Micro Classic, is still around while supplies last.

Gear Options:

• Standard
  • All gears are 20 DP 4140 Steel, Zinc Plated, and contain symmetrical features.
• Weight Relief 
  • Gears are pocketed where possible. The material properties are the same as standard gears. Some gears are too small to reasonably pocket. This includes;
    • 3/8 in. hex bore gears between 25 and 52 tooth.
    • 1/2 in. hex bore gears between 30 and 56 tooth.
• Exclusions
  • To save money, if you already have gears for the ratios desired, you can elect to receive only the gears you need.

Shaft Options:

All shafts are made of Steel; 1018, 1215, or 12L14, and zinc plated for rust prevention. For speed and distance measurements, all shafts are machined with a socket to accept a steel dowl or magnet for various encoders. The AM14U shaft has this feature at both ends.

• Long
  • Length: 5.6 inches long.
  • Usage: For large drive rail spans or when multiple motion components must be driven, this extra-long shaft is a great choice.
• Short
  • Length: 3.6 inches long.
  • Usage: Great for driving individual motion components such as a hub or pulley. Supporting the output shaft end with a bearing is not always needed.
• AM14U
  • Length: 5.1 inches long.
  • Usage: This shaft should be used when installing a ToughBox Micro S in an AM14U drive base. The length is designed to be perfectly supported on the output shaft end.

Plate Options:

• Flat: For face mounting a ToughBox Micro S to various structures or members wherever you need it to live! It also keeps the insides from falling out.
• Angled: When you want to secure the ToughBox Micro S to a flat component face like 2x1 box tube or channel.
• None: Use this option if you wish to secure the ToughBox Micro S straight to your own flat plate. We do this on the AM14U for mecanum drive trains!

Break-in Period:

All AndyMark gearboxes require grease for proper operation and long life. Grease is included with your gearbox, so please use it. We encourage you to power the gearbox continuously for 30 minutes without grease to allow the gear teeth to wear in. We design with short run times in mind, this 'run in' period for smooth gearbox operation is recommended. Once completed, thoroughly grease the gear teeth periodically to ensure smooth operation.
