The invention relates to the technical field of gear meshing analysis, in particular to a gear tooth contact performance analysis method. The gear tooth contact performance analysis method comprises the following steps that a first instantaneous conjugate meshing line and a second instantaneous conjugate meshing line are calculated according to the construction of a small gear reference tooth surface and a large gear reference tooth surface, then the first instantaneous conjugate meshing line and the second instantaneous conjugate meshing line are discretized, the distances between corresponding discrete points are calculated, the shortest distance among discrete point pairs is the transmission error of meshing between the small gear tooth surface and the large gear tooth surface, and the corresponding discrete points are meshing points; and the transmission error is separated and then an instantaneous contact curve can be separated to obtain a tooth surface contact pattern. According to the gear tooth contact performance analysis method, the meshing points can be determined only by establishing two nonlinear equations, mathematical models of the tooth surface contact analysis and the edge contact analysis are unified, and the problem that the calculation process of the gear tooth contact performance analysis is complex is solved.
Description
technical field [0001] The invention relates to the technical field of gear mesh analysis, in particular to a gear tooth contact performance analysis method. Background technique [0002] The gear tooth contact analysis method is used to predict the tooth surface impression and transmission error during gear meshing transmission, and it is an important means to evaluate the gear meshing performance. The currently widely used gear tooth contact performance analysis method is mainly based on the microscopic geometric topology. The core content is to determine the meshing point pair and the transmission error by solving five nonlinear equations according to the contact condition of the meshing point (the normal vector is collinear and the position vector is the same). , the instantaneous contact curve is simplified to a straight line according to the micro-geometric topology of the meshing points. This method needs to solve five nonlinear equations, the setting of the initial ...
