The invention discloses a gear tooth deformation calculation method introduced by measurement force in the measurement of gear double-sided meshing, and belongs to the field of precision testing technology and instruments. The steps are as follows: (1) Measuring the force during double-face meshing will cause the gear teeth to deform, so that the center distance of the double mesh will change, and then the error curve of the double mesh will be affected. Calculate the gear tooth deformation caused by the measurement force along the left and right meshing lines, and superimpose the tooth deformation on the left and right meshing lines according to the meshing phase, so as to obtain the change of the double tooth center distance caused by the measuring force. (2) The amount of deformation along the meshing line is the component of the measured force along the meshing line divided by the gear stiffness on the meshing line. (3) The tooth stiffness on a single meshing line is the superposition of the stiffness of each contact point on the meshing line. (4) The stiffness of the gear at a contact point is composed of three parts: the bending stiffness of the gear tooth, the shear stiffness and the contact stiffness of the tooth surface. (5) The bending and shear stiffness are calculated by the cantilever beam model, and the contact deformation is calculated by the Hertz formula.
