摘要： Provided is a gear grinding machine which can dress a grinding stone while a gear is held attached to the machine regardless of the size of the gear. To this end, the gear grinding machine (1) engages and mutually rotates a work (W) and the grinding stone (17) to thereby grind the work (W), wherein the gear grinding machine is equipped with a turning table (22) which holds the work (W) and rotates around a work rotating shaft (C), and a pivot table (31) which is pivotably supported around the work rotating shaft (C); and a dresser (40) which is capable of dressing the grinding stone (17) is provided on the pivot table (31), the pivot table (31) being pivoted to move the dresser (40) between a dressing position (D1) and a retreat position (D2).

摘要： Based on a left tooth surface(28) having a maximum accumulated pitch error ALmax (when clockwise direction is a positive direction) and a right tooth surface(29) having a minimum accumulated pitch error ARmin (when clockwise direction is a positive direction), which are conceived to most likely have insufficiently ground portions, a correction value δθ which cancels these accumulated pitch errors for suppressing the accumulated pitch error after grinding is obtained. A reference tooth groove angle θ 0 is corrected by the correction value δθ, thereby obtaining the meshing angle θ of the work gear. All teeth detection and signal processing in a short period of time is realized by using a displacement sensor and a high-speed meshing-dedicated circuit board.
