Research on meshing performance of high-order segmented topology modification in face gear pair
In order to enhance the load-bearing performance of face gear transmission and reduce its sensitivity to installation misalignment
a high-order segmented topological modification method based on a predefined contact path was proposed.
Methods
2
Firstly
2nd-order and 4th-order segmented modification functions were designed along the predefined contact path of the pinion and the instantaneous contact line direction
respectively. Based on the surface superposition method
the equation of the modified tooth surface was established. Subsequently
the tooth contact analysis (TCA) equation incorporating installation errors was derived. The influence of parameters such as predefined contact path angle
modification length
modification curve order
and maximum modification amount on the contact characteristics of face gear pair under different installation error conditions was investigated. Finally
a comparative analysis of the load-bearing contact characteristics of the face gear pair under different modification functions and modification amounts was conducted using the finite element method.
Results
2
The calculation results show that compared to 2nd-order modification
the 4th-order modification method reduces the contact stresses of the tooth surface and the error amplitude of load-bearing transmission. Furthermore
the contact trace extends from the root of the inner diameter tooth of the face gear to the tip of the outer diameter tooth. The high-order segmented modification method can reduce the sensitivity of the face gear pair to installation errors
optimize the load distribution of the tooth surface
and enhance meshing performance.
