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; (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.
