Nettet29. nov. 2024 · A hob is the cutting tool that’s used by the hobber to cut the teeth into the blank workpiece. Hobs are cylindrical in shape and have helical cutting teeth that feature grooves which run the length of the hob. These teeth help in cutting and chip removal. Special hobs are also designed for certain products like sprocket gears. NettetHobbed Gears - Gear Technology Magazine

NettetBasic Parameters ¶. The basic parameters defining the geometry of helical gear teeth are normal module, normal pressure angle, number of teeth, and helix angle. Symbolically, each is denoted as mn m n, αn α n, z z, and β β, respectively. Different basic parameters could be used, but these are the most common. NettetA flat-root ramp on the hob tooth profile will generate a chamfer on the tooth to provide clearance at the major diameter between the external and internal mating teeth. A fillet-root spline hob has a smooth radius so as not to generate a hard chamfer on the spline teeth tips. Download the brochure.
