Nettet15. apr. 1999 · A critical factor in spiroid gearing manufacturing technology are the spiroid hobs, which like spiroid gearing are of two types—Helicon (Fig. 1) [2], [3] and Spiroid (Fig. 2) [3] (when discussing both of them, the term ‘spiroid’ is used).Spiroid gears such as worm gears are cut after Oliver’s second principle [2], [5], i.e. the spiroid hob is an … NettetThe Circular Pitch defines the width of one tooth and one gap measured on an arc on the pitch circle; in other words, this is the distance on the pitch circle from a point on one tooth to the corresponding point on the adjacent tooth. This is equal to π divided by the Diametral Pitch. CP = Circular Pitch in inches DP = Diametral Pitch
