he Bearing Tooth Gear is actually a functional technology that uses bearings in the construction of the gear teeth and of course bearings are being used for axle bearings to mount the gear housing. Currently there are 2 U.S. Utility Patents on the Bearing Tooth Gear (BTG) technology (5,371,704 & 5,704,248) and further Patents are undoubtedly available, if a market could be established for the BTG technology. The BTG technology use bearings inside the bearing teeth, or, the bearings are set in the gear housings. The bearing teeth are in rolling contact, instead of sliding contact, like conventional gear teeth designs. While it is obvious that rolling friction is much lower than sliding friction and therefore less energy is needed to rotate the gears; there are actually a number of other advantages to using rolling contact, instead of sliding contact. I will go into further detail regarding the advantages of the BTG technology in the following questions.
