摘要： PURPOSE: To allow a gear hob to be meshed with a machined gear automatically with high accuracy by shifting the angle position of the machined gear on the basis of the slippage between the generating centerline and a cutting edge position and the slippage between the generating centerline and a tooth space position. CONSTITUTION: At the time of detecting the position of a gear hob cutting edge, a gear hob is rotated by a hob shaft driving motor MB to detect the one-rotation signal of a hob shaft, and the pulse number of a position coder is counted. In the on position of a detecting head, the pulse count number is instructed to a numerical control device NC from a program sequencer PMC so as to obtain a turning angle Δθ. A Y-axis motor MY is driven, and the distance between intersection points Y1, Y2 is detected by the detecting head and outputted to a comparator. On the basis of this signal, the numerical control device NC computes slippage ΔY between the generating center and the cutting edge center so as to obtain the generating center cutting edge position set data in the axial cutting start position of the gear hob, and the distance ΔY is shifted in the Y-direction to obtain a cutting edge position.

摘要： PURPOSE:To cause relative movement of a tool and a gear material and cause separation therebetween through operation of a returning motor in a tool/gear- material engaging and returning device for a gear working machine, when service interruption occurs or when an abnormality occurs in devices associated with the gear working machine. CONSTITUTION:When electric supply is interrupted, it is detected by service interruption detectors RA1, RA1'. When an abnormality occurs in a specified device of a gear working machine, it is detected by abnormality detectors RA2, RA2'. As a result, a switching means SCR is inserted into a connection circuit between a d.c. power source 7 and a returning motor 6. In response to detection signals from the service interruption detectors RA1, RA1' or from the abnormality detectors RA2, RA2', therefore, the d.c. power source 7 is connected to the returning motor 6. Thus, the returning motor 6 is driven by the d.c. power source 7, so that a tool and a gear material make their relative movement and are moved away from each other.

摘要： PURPOSE:To compute a rotation quantity of a gear to be worked with simple circuit constitution, generate drive pulse of a servo motor 2, and synchronously rotate the gear and a screw-like tool, in a NC gear cutting machine in which the gear W to be worked is worked with a screw-like tool such as gear hob T or screw-like grinding wheel. CONSTITUTION:A gate 15 is opened by the rotation quantity detection pulse of an encoder 6 to detect a rotation quantity of a screw-like tool, oscillation pulse of a pulse oscillator 14 is passed through the gate 15, the passing pulse through the gate 15 is counted with a first and a second preset counters 16, 17, and when the number of count is reached to a first setting value, the gate 15 is closed with the first preset counter 16, and when the number of count is reached to a second setting value, the drive pulse of a servo motor 2 is generated with the second preset counter 17. The first setting value is a value Kh.g, a constant Kh multiplied by the factor (g) of the screw-like tool, the constant Kh is the number of drive pulse Pw of the servo motor per unit rotation of the gear W divided by the number of rotation quantity detected pulse Pt, namely the value Pw/Pt, and the second setting value is the number of teeth Z of the gear W.
