Embodiment Construction

[0056] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below in conjunction with the accompanying drawings and through specific embodiments.

[0057] In order to facilitate the understanding of the present invention, the gear meshing theory is introduced as follows: According to the gear meshing theory, at any moment in a meshing cycle T of gear pair meshing, there are at most two pairs of gear teeth participating in meshing at the same time; In the meshing period T, the driving wheel or the driven wheel is in its meshing area, and at most 3 pairs of adjacent gears enter into the meshing area successively. That is, there are cases of early engagement and late engagement.

[0058] When calculating the time-varying mesh stiffness of a gear pair, it is necessary to calculate the tooth stiffness of the driving wheel and the driven wheel respectively. In the gear meshing theory, in the single tooth me...

Abstract

The invention relates to a method for analyzing gear pair meshing characteristics. This gear pair meshing characteristics analysis method is based on the finite element model and uses analytical methods to analyze the overall deformation and local contact deformation of the gear pair, and obtain the time-varying meshing stiffness and tooth root bending stress. This method avoids nonlinear contact iteration and has high calculation efficiency and high calculation accuracy; this method can consider tooth tip modification, extended meshing and complex tooth base of spur gear pairs.

Description

technical field [0001] The invention belongs to the technical field of mechanical dynamics, and in particular relates to a method for analyzing the meshing characteristics of a gear pair. Background technique [0002] In gear transmission, mesh stiffness excitation is one of the main dynamic excitations of gear meshing. Accurate evaluation of meshing characteristics is very important for predicting dynamic performance and improving design of spur gear pairs. At present, the existing methods for analyzing the meshing characteristics of spur gear pairs have the following characteristics: [0003] 1) Finite element method [0004] When the finite element method simulates the contact process of the gear pair, the contact element is usually established to simulate the real contact relationship. This method requires a sufficiently fine mesh of the contact area to ensure convergence. Because of the large-scale nonlinear iterative solution involved, the efficiency of this method ...
