HIRTH COUPLING WITH SECONDARY PROFILE ANGLE

The invention relates to a pre-machined blank for a machine element (1, 2) comprising a Hirth coupling (3, 4), which has a plurality of teeth with central symmetry and tooth gaps therebetween, wherein: each tooth has a tooth flank (12) with a profile angle (α1), a secondary flank (13) with a seconda...

Beschreibung
Zusammenfassung:	The invention relates to a pre-machined blank for a machine element (1, 2) comprising a Hirth coupling (3, 4), which has a plurality of teeth with central symmetry and tooth gaps therebetween, wherein: each tooth has a tooth flank (12) with a profile angle (α1), a secondary flank (13) with a secondary profile angle (α2), and a tooth root region (14); the secondary flank (13) transitions continuously tangentially into the radius of the tooth root region (14); the secondary profile angle (α2) is smaller than the profile angle (α1); a grinding allowance (10) of material is present in the region of the tooth flank (12) after pre-machining and before finishing, preferably final grinding; and no grinding allowance is present in the region of the secondary flank (13) after pre-machining and before finishing, preferably the final grinding.
