    CIM Sport Gearbox 12:1 HD Ratio

    The CIM Sport is a competition tested high performance line of planetary gearboxes from AndyMark and BaneBots. The CIM Sport features numerous improvements over previous planetary gearboxes used on FIRST Robotics Competition robots. 

    MFR Part #: am-4008_012
    $149.00
    Availability: 2 in stock

    The cold formed steel gears inside this gearbox are a 0.7 Module tooth profile which is 40% larger than the vast majority of planetary gearbox gears previously used on competition robots. The gears are larger, but the housing's size has been optimized to reduce any unnecessary volume. This means you get more reliability without sacrificing precious space. This housing is also one solid piece of aluminium, ensuring that there is no possibility for misalignment of the stages during assembly or during the rigors of match play. 

    Three stage, and now optionally two stage, versions of these gearboxes also feature an "HD" stage, with gears approximately double the face width of the other stages as well as a strengthened carrier plate. These larger gears on the output stage ensure that it will handle heavy or cantilevered loads without worry. The carrier plates are made of hardened 4140 steel and interface to the output shaft with a robust hex bore. New for 2019 we are opening up the use of every available gear ratio with every available motor input meaning there are some combinations that could theoretically exceed the gearboxes design characteristics. As such the blanket warranty we offered on these gearboxes in the past will be discontinued for future purchases. Rest assured that AndyMark still stands behind our product 100% and if you feel that there is a problem with your gearbox or any of our products please contact us and we will make it right. To help you decide which gearboxes to use for your application please reference the below table which includes the maximum torque that the gearbox is designed to take before it will fail.

    A free packet of red tacky grease (am-2768) is included with every gearbox purchased. This grease must be used to coat every internal surface of the gearbox before use. 

    The CIM Sport includes mounting hardware for any CIM style motor including the CIM, the MiniCIM, or the NEO. To install one of these motors, first remove any installed pinion from the motor and press on the included pinion gear using an arbor press or bench vice. This press fit ensures a solid mechanical connection between the pinion gear and the motor. This pinion assembly is not susceptible to vibration and never needs to be checked once installed. All ratios of Blue Sport Gearboxes use a 4:1 input stage, with the same tooth count pinion, so motors and gearboxes can be switched out with ease.
    The CIM Sport can be used with the optional alternative short back block (am-3769). This can be used to shorten any ratio of the gearbox by 0.92 in. and lighten it by 0.23lb. To use this back block the CIM output shaft must be cut down by 0.92 in. and the pinion pressed onto this shortened shaft. For detailed instructions please see the Motor Installation Guide under the downloads tab.

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

    #am-3462_green
    $8.00
    (72 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.

    These aluminum box extrusions are robust and lightweight solutions for custom robot frames, superstructures and mechanism construction. Made to all of your favorite English sizes, the classic 2x1 thin wall tubing is now joined by its thicker-walled counterpart. We have also introduced two thicknesses of 1x1 sizes that teams know and love to build their medium-sized mechanisms. 



    For smaller mechanisms, we recommend using our 5/8 square box tube that is also compatible with our S3 line of brackets and gussets.



    Available Sizes:

    • 2 x 1 x 1/16 in. (0.063 in.) 6061-T6 alloy
    • 2 x 1 x 1/8 in. (0.125 in.) 6061-T6 alloy
    • 1 x 1 x 1/16 in. (0.063 in.)6061-T6 alloy
    • 1 x 1 x 1/8 in. (0.125 in.)6061-T6 alloy
    • 5/8 x 5/8 x 1/16 in. (0.063 in.) 6061-T6 alloy
    • All lengths are (+/- 1in)
