<p>The present invention provides a convex processing which can perform crowning without increasing the volume and maintaining the mechanical strength of gear machining equipment. The gear processing device of the present invention includes: a base station which is arranged in the pedesta and has an inner gear-shaped tool unit which is meshed with the processed gear for processing; a tool supporting unit is arranged on the pedestal for supporting the processed gear in a free rotation way, and is relatively separated from the tool unit; and a first rotary driving mechanism which rotates surrounding about the tool and the second axis which is orthogonal to the first axis of the rotation center of the tool.</p> |
