    2" Compliant Wheel, 1/2 inch Hex, 35 Durometer Green

    #am-3462_green
    $8.00
    (In stock)

    Compliant wheels are not intended for moving robots, but moving objects. Compliant wheels give way to allow rigid objects to be manipulated easily. A line of multiple wheels on a driven hex shaft creates a very effective roller that ignores variations in the objects being driven. This makes for high-performance intakes and internal conveyors. The wheels are sized for an interference fit and tend to stay in place on a shaft, though a shaft collar may be used to make absolutely sure the wheels stay clear of other mechanisms or maintain consistent spacing.

     

    The hex bore versions of this wheel are undersized, and are intended to be an interference fit on their respective hex shafts. This interference fit allows for effective torque transfer from the hex shaft to the wheel, as well as allowing the wheel to remain in place along the shaft without the need for spacers or collar clamps:

     

    Compliant Wheel Sizing

     

    Different durometer ratings give each wheel unique characteristics. Green wheels (35A durometer) are the softest and most compliant around objects, while orange (40A), maroon (45A), and blue (50A) wheels are increasingly firm. The increased firmness also allows the latter wheels to carry a higher RPM rating. Check out the downloads tab for a chart showing wheels and their maximum RPM.

    This is the "500EX Hex Hub" the bore is a 1/2" Hex Hole. It is a slightly different version of the 500 Hex Hub. It is manufactured differently, as it is extruded. Also, there is a 1.124" diameter boss on each side of the hub flange, providing a location for 1.125" bore flat sprockets. Are you having a hard time keeping your sprocket concentric with your hub? This hub is the trick.

    This is the hub featured in the 2014 and 2015 Kit of Parts Drive Chassis and fits all AndyMark wheels.

    6" HiGrip Rubber Tread Wheel Rev2

    #am-0940b
    $18.45
    (In stock)

    FTC Note: This product is NOT legal for FTC, we recommend our Stealth Wheel.

    Product Overview: 
    This is a 6" diameter wheel with a polycarbonate body and a TPU rubber "HiGrip" tread profile. This wheel features a 77A durometer tread material that is durable with long-life wear characteristics. Use this wheel for great tread life and good drivetrain response. 

    We feel that these wheels are a more durable option for teams' drivetrains. While they provide good traction, they make for a maintenance-free wheel for the average team. Under normal circumstances we feel that these wheels will last most FIRST Robotics Competition teams the entire season. 
    No bearings or hubs are included in this wheel. 

    Specifications:

    • Diameter: 6 inches
    • Body Material: Polycarbonate, black
    • Tread Material: TPU rubber, 77a durometer
    • Bore: 0.95 inch, with bearing pockets of 1.124 inch diameter x 0.25 inch deep on both sides
    • Weight: 0.5 pound
    • Bolt Pattern: six holes (0.17 inch diameter) on a 1.875 inch diameter bolt circle
    • Coefficient of friction: 0.95-1.0 static (on tight pile carpet)
    • Coefficient of friction on HDPE: 0.31
    • Side Load: In excess of 600 lbs at tread surface
    • Load capacity: 90 pounds

    Usage: 

    • Use #10-24x3/4 thread forming screws to attach sprockets or hubs to this wheel. 


    With Axle and Hub:

    • If you wish to drive this wheel with an Axle and Hub, you can pick your hub by fitting any of the AndyMark hubs (not included) to this wheel. If this is your choice, then no bearing is needed. Use #10-24x3/4 thread forming screws to fasten a hub to this wheel.

    With Sprocket:

    • If you wish to drive this wheel with a sprocket, then the sprocket needs to be attached to the side of the wheel, and two ball bearingsneed to be pressed into the wheel (one on each side). The ball bearing must have a 1.125" od. For a 1/2" id, use am-0181 or am-0029. For a 3/8" id, use am-0209. Use #10-24x3/4 thread forming screws to fasten the sprocket to the wheel.

    With Bearings:

    • To press bearings into this wheel (for a free spinning wheel or for use with a sprocket), two ball bearings need to be pressed into the wheel (one on each side). The ball bearing must have a 1.125" od. For a 1/2" id, use am-0181 or am-0029. For a 3/8" id, use am-0209.
