A method for the determination of the optimal polynomial functions for the conduction of machine-tool setting variations in pinion teeth finishing in order to reduce the transmission errors in spiral bevel gears is presented. Polynomial functions of order up to five are applied to conduct the variation of the cradle radial setting and of the cutting ratio in the process for pinion teeth generat...

Diagnostics of faults in gears requires development of reliable condition indicators. A large number of condition indicators, which are based on statistical moments of the synchronous average and its derivatives (difference and residual signals) were previously suggested. This study evaluates the efficiency of different gear condition indicators that are based on statistical moments and compare...

The paper primarily employs the 3D calculation method of helical gear-meshing line and meshing position, in addition to traditional stiffness calculation. This analysis correction load-sharing are beneficial for improving assembly process high-powered critical equipment. dynamic models rigid–flexible coupling, velocity–torque, force planetary gear trains nuclear power plants established based o...

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 m...
