Abstract

403,886. Gear grinding machines. MAAG-ZAHNRAEDER UND MASCHINEN AKT.-GES., and ERNST, D., 219, Hardstrasse, Zurich, Switzerland. June 6, 1933, No. 16255. [Class 83 (iii).] In a gear-grinding machine, such as that described in Specification 15617/13, [Class 83 (iii), Metals, Cutting], wherein a gear blank 1 is rolled past a pair of grinding discs 6 and is controlled by means of tensioned flexible bands 4 passing round a cylindrical segment 3 the effective profile of the segment is modified from the theoretical circular profile in order to impart to the profile of the gear teeth, slight deviations from the true involute form. These deviations may compensate for elastic distortion of the teeth under full load or for small pitch errors. In one form, Fig. 2, the rolling segment has a profile 71 differing from the circular profile 7. A similar result may be attained by the use of a circular segment in conjunction with flexible bands of varying thickness. In some cases a non-circular segment may be used with bands 4 of varying thickness.
