  • How to Design and Install Bevel Gears - Gear Technology

    Contact patternA critical attribute of any bevel gear design . is its contact pattern (Fig. 3). Simply stated, the contact pattern is the area in which the gear teeth come in contact as they engage and disengage during their rotation. When a gear is installed in a gearbox and is powering the designated application, there are varying degrees of pres- sure—or load—on the gear teeth. These
