A new form of oval noncircular bevel gear transmission was proposed,which can transfer variable ratio motion and power between the intersecting shafts.A mesh coordinate system on the pitch cone of the oval noncircular bevel gear was established in which the formulas of transmission ratio and displacement etc. were deduced based on analyzing meshing theory. The influences of eccentricity ratio on kinetic characteristics such as the displacement, the angular, the oscillating line of pitch cone contact generator and periodicity were analyzed. Having finished experimental researches, comparisons between experimental results and theoretical analysis were made to get its laws of transmission and methods for design and to verify the drive characteristics of oval noncircular bevel gear.
