Patent ID: 8813595

Claim:
A method of adjusting a meshing position of a hypoid gear including a first gear and a second gear which meshes with the first gear for transmitting a rotary motion of the first gear in a direction which is different from a direction along which a rotational shaft of the first gear extends, comprising the steps of: displacing the second gear along a direction of a rotational shaft of the second gear a plurality of times while the second gear is being held in mesh with the first gear; measuring transmission errors at respective positions to which the second gear is displaced and plotting a relationship between distances by which the second gear is displaced and the measured transmission errors; evaluating hypothetical transmission errors between the measured transmission errors from the measured transmission errors; subtracting the measured transmission errors and the hypothetical transmission errors from a maximum allowable transmission error to determine differences therebetween; integrating the differences with respect to the distances by which the second gear is displaced, to determine the area of a region surrounded by the differences and the maximum allowable transmission error; and dividing the region with a dividing line at a given area ratio and establishing a point of intersection between the dividing line and the distances by which the second gear is displaced as a meshing position of the second gear.
