Basic study on transmission error for gear made from different metals laminated in width direction to provide rigidity distribution

To improve the load characteristics of transmission error for helical gears, a gear made laminated materials is proposed. The has three layers in which metals with different rigidities are tooth width direction. on both sides from same metal, and metal used central layer. A theoretical analysis was performed to investigate effects arranging high- low-rigidity changing conventional homogeneous material gear. can be reduced combination high-rigidity layer side layers, low maintained over wide range by adjusting appropriately. principle reduction that, rigidity along one-pitch meshing progress materials, elastic deformation teeth largely cancel out rotational fluctuations caused flank shape range. pair gears manufactured, testing confirmed that lower than material. potential achieve vibration/noise generation wider
