The invention discloses a wind power gear box torque arm strength checking method, which comprises the following steps of: performing equivalent bending moment conversion on each bending moment around a y axis, each bending moment around a z axis, each y axis stress and each z axis stress in an obtained hub center load spectrum to obtain a total equivalent bending moment set of a bearing; obtaining each angle interval obtained by dividing according to a preset angle interval; selecting the maximum bearing total equivalent bending moment corresponding to each angle interval from the bearing total equivalent bending moment set; and performing torque arm strength checking according to each load working condition in the hub center load spectrum corresponding to each maximum bearing total equivalent bending moment. By applying the method for checking the strength of the torque arm of the wind power gear box, the comprehensiveness of checking the strength of the torque arm of the gear box is improved, and the overa
