    57 Sport Gearbox 4:1 SD Ratio

    The 57 Sport is a competition tested high performance line of planetary gearboxes from AndyMark and BaneBots. The 57 Sport features numerous improvements over previous planetary gearboxes used on FIRST Robotics Competition robots.

    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 57 Sport includes mounting hardware for any 500 or 700 series motor including the AndyMark RedLine, the VexPro 775pro, the AndyMark RS775-5, the BaneBots RS775, the BaneBots RS550, and the AndyMark NeveRest. 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.

    Bearing, 1/2 inch Hex Bore, Flanged, (FR8ZZ-HexHD)

    #am-2986
    $8.00
    (87 En stock)

    This is a Heavy Duty Hex Bearing which outperforms our previous 1/2" Hex Bearings as it has a Heavy Duty Inner Race. This FR8ZZ-HexHD bearing, 1/2" hex bore, flanged, heavy duty inner race, shielded ball bearing, has an inner race that is thicker and stronger than our recent offering of a similar bearing (am-0279). This bearing has more material between the corners of the hex bore and the edge of the race making it stronger and much less likely to crack under high load.

    This bearing is guaranteed to have a stronger, thicker race. 100% of these bearings have been quality checked for a smooth fit over 1/2" hex stock here at AndyMark. Many of our long-time customers will recognize this bearing, as it is the same version we sold back in 2008-2011, and we did not have any failures. Now, it is renamed and quality checked for your high load needs - including drive chassis with cantilevered wheels.


    Specifications:

    • Inside diameter: 0.500-0.502 inch hex bore
    • Outside diameter: 1.125 inch
    • Flange thickness: 0.062 inch
    • Overall thickness: 0.312 inch
    • Weight: 0.05 pound

    4" Compliant Wheel, 3/8" Hex Bore, 35A Durometer, Green

    #am-3562_green
    $12.75

    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 axle creates a very effective roller that ignores variations in the objects being driven. This makes for high-performance intakes and internal conveyors.



    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), blue (50A), and black (60A) 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. 

     

    Please note maroon wheels are only intended for use in FTC. If more powerful motors are used to drive it the spokes may fail.

    0.50 in. Hex and Keyed Shaft Coupling

    #AM-1560
    $25.00
    (15 En stock)

    Whether you have shafts that are too short or shafts of different types, this coupling will solve every component connection issue you've had! Need to combine multiple hex shafts, multiple 1/2-inch keyed shafts, or convert between hex and keyed? This coupling solves all at a better price than anyone else can offer!

    Shaft Compatability

    This coupling has geometry to capture 0.50-inch hex shafts with an inside hex of 0.51 to 0.52 inches as well as 0.5 inch keyed shafts with a 1/8th inch keyway with a keyway width of 0.128 inches to 0.131 inches.

    AndyMark 775 RedLine Motor with 16 Tooth 57 Sport Pinion Gear Installed

    #am-3775a_16t
    $42.00
    (En stock)

    This updated version of the AndyMark 775 RedLine Motor is an even faster and more powerful version of this popular 775-class motor platform. With a power rating of up to 363W, this motor is capable of delivering even more immense power in the same small lightweight package over the previous version. This ball-bearing supported, air cooled motor is best used in high-speed applications where the motor will not be stalled for long periods such as shooters, conveyors, and intake mechanisms. With sufficient care and attention to your application's traction limit, this motor can be effective in FRC drive applications as well.


    This variation of the RedLine comes with a 16 tooth, 0.7 Module pinion and mounting screws (am-3768) already installed allowing this motor to be installed into either a 57 Sport or a Dual 775 Sport gearbox. Not only does this take the risk of damaging the motor during pinion installation out of your hands, it also means that this counts as a COTS part in FRC.

    42 Tooth Pulley

    #am-2234a
    $11.95
    (En stock)

    This is the 42 tooth pulley used in the AM14U family of chassis. It works with all 5 mm pitch HTD timing belts. This pulley has a 1.875 in. bolt circle making it easy to attach to many of our motion components. It also has a locking pattern that is compatible with many of our wheels.

    This pulley comes as two identical halves that mesh with each other to create one pulley that is the correct width for a 15 mm timing belt.

    Need to have two 15 mm belts on one pulley? Add in the 15 mm wide, 42 Tooth Pulley Extension (am-2813) and you can run two belts in two different directions.

     

    Specifications

    • Belt Profile: 5 mm pitch HTD timing belt, 15 mm wide
    • Bolt Pattern: 0.2 in. diameter holes, evenly spaced on a 1.875 in. diameter bolt circle
    • Bore: 0.95 in., with bearing pocket of 1.124 in. diameter x 0.25 in. deep
