摘要： PROBLEM TO BE SOLVED: To shorten a chamfer-processing time of a tooth form.SOLUTION: After simultaneously executing chamfer-processing of both side surfaces (A1 and A2) and a bottom part (B1) of the tooth form of an upper surface of a work object gear, by allowing the work object gear (w) and a screw-like grinding wheel (g) to abut at a torsion angle (θ) of 50 degrees of the outer peripheral edge of the screw-like grinding wheel (g) abutting on an outer peripheral edge upper part of the work object gear, on the work object grear (w), then, after separating both (w and g), the work object gear (w) is vertically inversely fixed to a rotary shaft, and the work object gear (w) and the screw-like grinding wheel (g) are also allowed to abut at the torsion angle (θ) of 50 degrees, to simultaneously execute the chamfer-processing of both side surfaces (A1 and A2) and the bottom part (B1) of the tooth form of the upper surface of the work object gear (w).

摘要： PROBLEM TO BE SOLVED: To provide a method for simply engaging a thread-like grinding wheel with a gear to be worked. SOLUTION: A gear to be worked 2 is simultaneously rotated with a grinding wheel 3. The rotation of the gear to be worked is accelerated to assure that the left tooth flank 22 of one tooth of the gear to be worked has kept into contact with a thread at its right tooth flank 32 of the grinding wheel by means of an ultrasonic sensor. Reading is applied to an angle (C+) to the central point o of the work axis of the gar to be worked, the right tooth flank of the m-th tooth of the contacted gear to be worked. The rotation of the gear to be worked is decelerated to assure that the right tooth flank 23 of one tooth of the gear to be worked has kept into contact with the thread at its left tooth flank 31 of the grinding wheel by means of the ultrasonic sensor. Reading is applied to an angle (C) to the central point o of the work shaft of the gear to be worked, the left tooth flank of the following m+1 th tooth of the contacted gear to be worked. Seconds of arc, α=C++C, is calculated to assign α/2 degrees as an engaging angle. The engaging position of the grinding wheel and the gear to be worked is the position rotated by α/2 agrees toward the right from the central point o of the work axis of the gear to be worked relative to the straight line running from the right tooth flank of the m-th tooth of the gear to be worked to the central point o of the work axis of the gear to be worked.

摘要： PROBLEM TO BE SOLVED: To provide a retrieval device capable of efficiently compensating unbalance of a rotary body such as a grinding wheel and a rotary shaft even if the grinding wheel has a complicated shape like a gear grinding device. SOLUTION: In this grinding device, the grinding wheel 3 having a cylindrical cavity for fitting in a central part is vertically fixed on a main shaft end 30 of a rotary shaft 20 of a rotary head by a flange 31. The grinding device is provided with balance compensation main mechanisms 33a, 33b attaching 2 or 3 balance pieces assembled in a grinding wheel fixing side and a grinding wheel rotation side of the rotary shaft across the grinding wheel and having a fixed radius (r) and a pair of annular grooves and a balance compensation submechanism 32 in which a pair of auto balancers 32a, 32b provided with a member having one set of balance pieces m1, m2, m3, m4 rotatable by a built-in DC motor on the same shaft core as a shaft core of the rotary shaft are independently provided inside the main shaft end of the rotary shaft positioned in the cylindrical cavity for fitting of the grinding wheel so as to divide the direction of thickness of the grinding wheel into two parts to compensate rotation balance of a grinding wheel shaft.
