Abstract

The embodiment of the invention discloses a gear pair meshing rigidity calculation method, which specifically comprises the following steps of: equally dividing single gear teeth in a meshing state according to basic geometric parameters and working condition parameters of a gear pair to obtain a plurality of straight tooth slices; according to the basic geometric parameters and the working condition parameters, calculating the load, the friction coefficient and the abrasion loss of each straight tooth slice; according to the load, calculating the friction coefficient and the abrasion loss, the bending rigidity, the axial compression rigidity and the shearing rigidity through adoption of an energy method; according to the bending rigidity, calculating the axial compression rigidity and the shearing rigidity, the single gear tooth rigidity; calculating meshing stiffness of a single pair of gear teeth according to the tooth stiffness of the single gear; calculating the meshing rigidity of the gear pair according to the meshing rigidity of the single pair of gear teeth; and therefore, the influence of friction and abrasion on the meshing rigidity of the helical gear pair is considered, and the meshing rigidity of the helical gear pair is accurately calculated.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission system dynamics, in particular to a method for calculating the meshing stiffness of a gear pair and a terminal device. Background technique [0002] Helical gears have stable transmission, strong load capacity and high transmission efficiency, so they are widely used in many industrial fields. The time-varying meshing stiffness is one of the main internal excitation sources of the gear transmission system. Accurately obtaining the actual meshing stiffness of the gear is an important prerequisite for dynamic analysis, vibration and noise reduction, and optimal design. During the meshing process of gear pairs, friction and wear on the tooth surfaces are inevitable. At present, the mesh stiffness calculation method mainly considers the influence of wear on the mesh stiffness of the involute spur gear pair. In the calculation of the mesh stiffness of the involute helical gear pair, th...
