Abstract
To reduce the herringbone gear transmission vibration and noise, an optimization design method about the meshing vibration of herringbone gear is provided with a controllable sixth-order polynomial function of transmission error. First, the polynomial coefficients of sixth-order polynomial function of transmission error curves can be determined by optimizing the aim at minimum root mean square value of herringbone gear meshing vibration acceleration based on loaded tooth contact analysis method and herringbone gear vibration model. Second, because of the existence of second-order frequency factors in the amplitude of loaded transmission error, the root mean square value of meshing vibration acceleration under the optimization of amplitude of loaded transmission error is worse than the value under the optimization of meshing vibration acceleration in resonant frequency. Third, a numerical simulation of example based on herringbone gear with different order transmission errors is performed, which proves tha...
Highlights
The standard involute cylindrical gear transmission systems, which are widely used in vehicle powertrain system, are sensitive to the manufacturing and installation errors, which can lead to edge contact, and induce vibration and damage.[1]
Experimentation and practice show that gear transmission system with higher order polynomial function of transmission error (HTE) has lower vibration, better noise performance, and more reliable stability compared to the second-order parabolic function of transmission error (2-TE) system
This article has provided a series of appropriate models to design and analyze the herringbone gear system with sixth-order transmission error based on meshing vibration optimization
Summary
The standard involute cylindrical gear transmission systems, which are widely used in vehicle powertrain system, are sensitive to the manufacturing and installation errors, which can lead to edge contact, and induce vibration and damage.[1] In order to improve the quality of gear meshing, tooth surfaces with different orders of transmission errors are obtained by gear profile modification technique.[2,3,4] Experimentation and practice show that gear transmission system with higher order polynomial function of transmission error (HTE) has lower vibration, better noise performance, and more reliable stability compared to the second-order parabolic function of transmission error (2-TE) system. Due to the interference in the machining process when tooth surface with higher order transmission error than sixth-order polynomial function of transmission error. Under the precondition for guaranteeing the structural strength, 6H-TE can still effectively reduce vibration acceleration and impact load at the transformation point of traditional transmission error
