A precise analysis has been made on the relationship between the resharpening of the type 3 worm hob and the tooth bearing of the type 3 worm gear. Firstly, a calculation method, which is used to calculate the axial profile of a new basic thread surface formed by the resharpened cutting edge of the worm hob, is obtained. Secondly, considering the new basic thread surface of the worm hob as a new thread surface of the type 3 worm, a caluclation method for the dimensions of the cone-shaped cutter, which is used to cut the new thread surface, is obtained. Thirdly, by applying these calculation methods to numerical examples of the worm hob, the profile error of the basic thread surface owing to the radius reduction made by the resharpening of the worm hob is clarified numerically, and the new dimensions of the resharpened worm hob and the cone-shaped cutter are obtained. Finally, the variation of the tooth bearing between the new wheel tooth surface cut by the resharpened worm hob and the thread surface of the original worm is discussed.
