Grinding body, in particular a double-taper grinding body

摘要

The invention relates to a grinding body, in particular a double-taper grinding body, for a gear grinding machine working by generation grinding with indexing control. The aim of the invention is to produce gearing with high transmission capacity in small dimensions and at a small mass. The object is to design a double-taper grinding body in such a way that, at the gear, the fillet radius of the fine-machining contour corresponds to that of the preliminary-machining contour. According to the invention, this is achieved in that, in the axial section plane of the double-taper grinding body 1, the transition from the flank line 2, lying at a profile angle alpha 0 to the profile centre line 6, to the line 5 defining the tip of the tooth is formed by a circular arc 3, the centre point M of which is at a distance from the line 5 defining the tip of the tooth at most by the size of the tooth-tip radius delta a0 which can be selected as a function of the module, and by an adjoining tangent 4 running at an angle alpha '0 of 35@ to 50@ to the profile centre line 6. <IMAGE>
