HARMONIC GEARING COMPRISING THREE-DIMENSIONAL TOOTH FORM

A three-dimensional tooth profile of internal teeth (20) in a strain wave gearing (1) is a basic internal-teeth tooth profile (20(0)) at an internal-teeth outer end (20a), and is a reduced tooth profile, in which the basic internal-teeth tooth profile (20(0)) is proportionally reduced only in the la...

Zusammenfassung:A three-dimensional tooth profile of internal teeth (20) in a strain wave gearing (1) is a basic internal-teeth tooth profile (20(0)) at an internal-teeth outer end (20a), and is a reduced tooth profile, in which the basic internal-teeth tooth profile (20(0)) is proportionally reduced only in the lateral direction, at other tooth-trace-direction positions. A three-dimensional tooth profile of external teeth (3) is a basic external-teeth tooth profile (30(0)) at an external-teeth outer end (30a), and is an increased tooth profile, in which the basic external-teeth tooth profile (30(0)) is proportionally increased only in the lateral direction, at other tooth-trace-direction positions. Tooth cutting process becomes easier than when only the external teeth (30) employ a three-dimensional tooth profile. Since the tooth profiles, which are proportionally reduced and increased only in the lateral direction along the tooth trace direction, are employed, it is further easier in tooth cutting process.
