OPTIMIZATION OF DYNAMIC MESHING BEHAVIOR OF HIGH SPEED SPIRAL BEVEL GEARS

A new approach for optimizing the dynamic meshing behavior of spiral bevel gear drives has been developed. It includes (1) the local synthesis for determining the machine tool settings, which can control the position and size of the contact pattern, the orientation of the contact path, the amplitude and the shape of the transmission error curve, (2) the tooth contact analysis (TCA) for simulating the geometry and contact of tooth surfaces, and (3) the loaded tooth contact analysis (LTCA) for simulating the tooth contact in transmitting torque. These techniques were used to constitute the design route with feedback. A numeral simulation on a computer shows that the excellent dynamic behavior of a spiral bevel gear drive, specially, with a contact ratio near 2.0 has been obtained by using the above mentioned method.
