Please see Page 165 for more details.② The backlash values shown in the table are the theoretical values for the backlash in the normal direction of a pair of identical gears in mesh.③ These gears produce axial thrust forces. See Page 167 for more details.④ Right handed and left handed helical gears in the same module are designed to mesh as a pair, but KHG gears are not interchangeable with SH type helical gears.*Above is for illustration purposes only and differs from actual tooth forms. To find more details, please see the section “4.3 Helical Gears” in sepa-rate technical reference book (Page 22).Normal ModuleTransverse Module[Caution on Secondary Operations]① Please read “Caution on Performing Secondary Operations” (Page 166) when performing modifications and/or secondary operations for safety concerns. KHK Quick-Mod Gears, the KHK's system for quick modification of KHK stock gears is also available.② Due to the gear teeth being induction hardened, no secondary operations can be performed on tooth areas including the bottom land (approx. 2 to 3 mm).③ While cutting off the entire hub may cause curvature deformation by residual stress, some products are straightened and annealed after refining the material.SpecificationsPrecision gradeJIS grade N6 (JIS B1702-1: 1998)JIS grade 2 (JIS B1702: 1976) Referencesection of gearRotating planeGear teethStandard full depthTransversepressure angle20°Helix angle21°30'MaterialSCM440Heat treatment Thermal refinined, tooth surfaceinduction hardenedTooth hardness50~60HRCFace width (E) 8Hub width (F)10Total length (G)18Screw offset (J) 5
