Such measurements should be corrected to corresponding values on transverse pitch circles for general comparisons.īORE LENGTH is the total length through a gear, sprocket, or coupling bore.ĬIRCULAR PITCH (p) is the distance along the pitch circle or pitch line between corresponding profiles of adjacent teeth.ĬIRCULAR THICKNESS (t) is the length of arc between the two sides of a gear tooth on the pitch circle, unless otherwise specified.ĬLEARANCE-OPERATING (c) is the amount by which the dedendum in a given gear exceeds the addendum of its mating gear.ĬONTACT RATIO (mc) in general, the number of angular pitches through which a tooth surface rotates from the beginning to the end of contact.ĭEDENDUM (b) is the depth of a tooth space below the pitch line. As actually indicated by measuring devices, backlash may be determined variously in the transverse, normal, or axial-planes, and either in the direction of the pitch circles or on the line of action. Gear Products and Suppliers | Gear Knowledge MenuĪDDENDUM (a) is the height by which a tooth projects beyond the pitch circle or pitch line.īASE DIAMETER (Db) is the diameter of the base cylinder from which the involute portion of a tooth profile is generated.īACKLASH (B) is the amount by which the width of a tooth space exceeds the thickness of the engaging tooth on the pitch circles.
