This track set includes a pair of 30-tooth silicone tracks, two drive sprockets measuring 1.38 inch (35 mm) in diameter, and two matching idler sprockets along with mounting hardware. The drive sprockets are designed to work with 3mm D-shafts, such as those on micro metal gearmotors.
This set contains components that are great for adding a tracked drive system to a small robot or vehicle. The flexible one-piece silicone tracks are designed to mesh with the drive and idler sprockets.
The drive sprockets are designed to press-fit securely on the output shafts of our micro metal gearmotors and 15.5D mm metal gearmotors. These gearmotors are intended to be mounted onto the side of the hub with the protruding teeth. The output shaft will slide into the socket easily at first but will achieve a snug fit when pressed through to the other edge of the hub.
The ideal spacing between the centers of the two sprockets is about 85 mm for the 30T tracks. Because the tracks are elastic, they will maintain tension even if you do not precisely match this distance. However, if the spacing is too short, they will be loose and more likely to slip off; if the spacing is too long, additional strain will be placed on the sprocket shafts, and the motor might not be able to turn as well.
