Title:
METHOD AND DEVICE FOR PRECISELY WORKING GEAR
Document Type and Number:
Japanese Patent JPS5627729
Kind Code:
A
Abstract:
In the finishing of gearwheels 33 by shaving or rolling using a toothed tool 3 in backlash-free mesh, depth infeed is controlled by measuring the distance 34 between the axis of the tool and gearwheel, and the infeed is stopped when the measured centre distance reaches a predetermined value. The device 40 for measuring the centre distance is mounted as close as possible to the tool and workpiece, to avoid errors due to mechanical deformation, temperature changes and other causes. For example it is mounted on a workpiece tailstock 31 and directly senses the tool holder 5. It comprises a probe 49 which is pressed back upon tool holder contact until it operates a contact at the predetermined position.
