DEVICE FOR MEASURING THE SINGLE FLANK ERROR OF A PAIR OF INTERMESHING TOOTHED WHEELS

摘要

A device for measuring the single flank error of a pair of intermeshing toothed wheels (3, 4) comprises two shafts on each of which one of the toothed wheels can be secured and on each of which also a disk (5, 6) can be secured having a diameter which corresponds to the diameter of the pitch circle of the toothed wheel on the respective shaft. A length of wire or tape (15) is wound around each of the disks, means (22, 23) being provided whereby said lengths of tape or wire can be unwound from the disks under tensile force to cause rotational movement of the disks and toothed wheels and any displacement difference between the lengths is neutralized. The lengths of wire or tape form parts of one wire or tape, which at a given point is fixedly connected to each of the disks, the wire or tape being guided between the disks in a loop round a measuring disk which is disposed on a displaceable carriage (7) whilst means (14) are arranged on this carriage for measuring rotational movement of the measuring disk.
