ABSTRACT:
A method for crown grinding of gear teeth having lengthwise curved teeth and a grinding head for the performance of the method, wherein there are ground the outer and inner flanks by means of rotatable, individually driven grinding elements or bodies, which are mounted in a grinding head rotatable about an axis of rotation and, during grinding, forming an outer as well as an inner envelope surface which is coaxial with respect to the axis of rotation of the grinding head. In order to be able to crown grind teeth flanks with greater accuracy, the axis of rotation of the grinding head is adjusted in spaced relation from a computation point of a tooth lengthwise line of the tooth flank, which is different from the spacing of the computation point of the tooth lengthwise line from a center serving as the center for non-crowned tooth flanks.
