The meshing gear teeth comprise cylindrical profile teeth on a gear or rack and circular arc profile teeth on the other gear or pinion. Each cylindrical profile tooth is preferably mounted for free rotation about the cylindrical axis of the tooth. Driving engagement of the gears rotates the contacting cylindrical teeth, thereby providing rolling contact between the meshing gear teeth. At any instant, at least two cylindrical teeth on one gear are in engagement with one tooth on the other gear. With the motion of the meshing gears, the cylindrical profile teeth rotate into and out of the roots of the other gear without loss of rolling contact from entrance to exit. The constant contact and multi tooth engagement prevents backlash relative movement between the gears.

A meshing gear construction comprising a first gear having a plurality of fixed teeth extending therefrom, said teeth alternatingly separated by a plurality of roots each having a radial centerline, faces on either side of each fixed tooth, each root being a continuation of a pair of faces of two adjacent teeth, a second gear having a plurality of rollers thereon rotatable relative to the second gear, said rollers meshing with the fixed teeth of the first gear, and said meshing comprising rolling contact of at least two rollers with one first gear fixed tooth at all instants of motion wherein said rollers comprise cylindrical rollers and the faces of said fixed teeth comprise circular arcs in profile and wherein a radial centers of fixed tooth circular arc face lies outside a pitch circle of the first gear and between the circular arc face and the radial centerline of an adjacent root.
