  4. Abstract:
  5. This article presents a method for determination of meshing force distribution on contact region of spur gear teeth. In this method it is assumed that there are inter-connected springs on the teeth profile. These springs treat as capacitive fields. The compliance matrices of these fields are determined from the results of finite element analysis done on 3-D model of a gear. The tooth compliance matrix is used as a reference data to determine the tooth deformations for any meshing situation. The meshing force distribution is calculated using this reference data and Hertz theory for contacting bodies. The results of this analysis help in stress analysis under real operation conditions and more reliable design of gears without needing 3-D contact model. So by this method the volume of the calculations is reduced remarkably. The method is applied to a spur gear pair, and the meshing force distribution and meshing stiffness is determined for two cases of ideal and misaligned contacts. Copyright © 2008 by ASME
