Design solutions for the shape of gear bodies depend on several factors such as size wheel, material, production method or use. Cast forged welded gears are used larger wheels. One requirements is weight reduction. Such an effort can be achieved by changing dimensions given while maintaining required stiffness gearing. The paper devoted to problem optimizing in order reduce gears, but best poss...

Abstract Ultrasonic scanning of large spiral bevel gears and the subsequent fracture analyses early-stage tooth flank fractures imply a mode II crack initiation under surface-parallel, orthogonal shear stresses. An iteration Dang Van criterion is presented that focuses exclusively on surface-parallel material planes, yielding standardizable approach for study in gears. It shown Van’s stress amp...
