Please see Page 31 for more details. ©10- and 11-tooth gears with a pitch of module 1.5 or greater are profile shifted gears (x = +0.5). Please refer to the below tables for calculating the center distance when assembled. © The backlash values shown in the table are the theoretical values for the normal direction for a pair of identical SSG Spur Gears with 30 teeth in mesh. ■ Center distance of Stock Spur Gears Meshing with Profile Shifted Spur Gears The table on the right shows the center distance of the spur gears (x=0) which can be meshed with profile shifted spur gears (x=+0.5) with module 1. Multiply by the actual module to determine your center distance. ■ Center distance when gear has 12 to 30 teeth (unit : mm) ■ Assembly distance of a profile shifted gear and the meshing rack a = -2 +H+xm Where a : Assembly Distance H : Height of pitch line of rack m : Module z_: No. of Teeth x : Profile Shift Coefficient Other Bevel Worm Screw Bevel Miter CP Racks Racks Internal Helical Spur Products Gearboxes Gear Pair Gears Gears Gears & Pinions Gears Gears Gears 46 For updated information, please see KHK Web Catalog.
