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.

Product Overview:
This 20-inch-long Nano Tube houses two complete gearboxes that drive 3 output shafts. Each has the same gearing and shafts as the Nano with 500 Key Shaft. Toughbox Nano Tube accepts two 2.5 inch CIM Motors. Hardware is included for attaching two of these motors.

This product is intended to be used as a complete drive module for the side of a 6-wheel-drive robot. The center shaft is slightly lower than the two outer shafts for better turning. A second tube is to be used on the opposite side of the robot in order to make the complete drive chassis. This same Nano Tube could be used for a 4-wheel-drive robot by removing the center shaft.

Version:
3-shaft, 500 Key

Specifications for each Gearbox:
  • Overall Ratio: 12.75:1 (standard)
  • Gear material: 4140 steel
  • Gear type: spur gears, 20 dp, 14.5 degree pressure angle
  • Body extrusion material: 6061 aluminum
  • Output shaft: 1/2 inch diameter, 4140 steel with 1/8" keyway
  • Input Gear: CIM Gear, 14 tooth, 0.315 inch bore w/ 2mm keyway
  • Large Cluster Gear: 50 tooth, 3/8 inch hex bore
  • Small Cluster Gear: 14 tooth, 3/8 inch hex bore
  • Large Output Gear: 50 tooth, 1/2 inch hex bore
Weight: 4.5 Pounds, not including motors or encoders

5.95:1 14 tooth 50 tooth 24 tooth 40 tooth


Weight Reductions with Optional Parts:
Aluminum Large Cluster Gear can replace the standard steel 50 Tooth Large Cluster Gear.
Aluminum Large Output Gear can replace the standard steel 50 Tooth Large Output Gear.

Optional 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. Here is a guide for encoder installation and alignment.

Aluminum Hex Output Shaft:
The Toughbox Nano Tube can use a hex aluminum output shaft and a long hex aluminum output shaft, but a FR8ZZ-Hex bearing MUST be ordered SEPARATELY to replace the FR8ZZ bearing supporting each output shaft. 		Product Usage:

Price: $545.00
Price: $595.00
Product Overview:
This is a 20" long Nano Tube chassis that is ready for a battery, wheels and controls.

This chassis comes without wheels, but with spacers, machine keys, and hardware to contain a wheel on the 1/2" diameter output shaft. This hardware is included to handle a 500 Key Hub (not included), which needs to be attached to the wheel of your choice.

Also, this is a bare mechanical chassis. A control system will need to be added to make this chassis come to life.

You can now even select if you want this as a Kit to assemble yourself, or pre-assembled by AndyMark in the options box above. Be aware that the Assembled version is more expensive and will have a 7-10 business day lead time as we build these to order.

Specifications:
  • Width: 21" (suggested, measuring from outside face of gearbox to opposite outside face)
    • With the Cross Hex Tubes included, this could be as much as 30"
  • Length: 20" (gearbox extrusion length)
  • Height: 3"
  • Estimated Chassis Weight: 23 lbs
  • Estimated Load Capacity: 400 lbs (based on wheels)
  • Motors: Four CIM Motors (am-0255)
  • Estimated Maximum Speed: (depends on wheels)
  • Estimated Maximum Output Torque at Each Wheel: 20 ft-lb
Included Hardware: Recommended wheel options:
Don't forget to buy Hubs and Spacers for each of these wheels.
