ABSTRACT

The meshing position of gear in the actual meshing process would deviate from the theoretical position, which is called gear engagement misalignment. The gear engagement misalignment could lead to changes in actual meshing characteristic of gear, and then influence gear’s meshing capability. Therefore, it is necessary to analyse the actual meshing situation of gear in detail for gear design. This paper aims at the three typical meshing misalignment forms of gear, using finite element method to establish a gear meshing model, and analysing gear contact ratio, contact stress distribution and size of contact zone, and the contact stress of gear in different meshing misalignment values. Then the impact of the meshing misalignment on gear meshing rule is analysed.
