Beschreibung
Zusammenfassung:	The present invention relates to a harmonic reducer which comprises: a rigidity internal gear; a flexible external gear engaged with the rigidity internal gear; and a wave generator which is pressurizedly in contact with the flexible external gear. An outer circumferential side of the wave generator is designed to be a variable curvature surface by setting a specific coefficient to improve a contact area between the wave generator and the flexible external gear. A fretting abrasion phenomenon is improved after the wave generator is installed in a rigidity external gear by increasing the contact area to improve power transmission efficiency and reduce a delay error. 본 발명은 하모닉 감속기에 관한 것으로, 강성 내접 기어, 강성 내접 기어에 맞물리는 가요성 외접 기어, 및 가요성 외접 기어에 가압적으로 접촉되는 파동 발생기를 포함하고, 특수한 계수 설정에 의해 파동 발생기의 외주변을 가변 곡률 표면으로 설계하여, 파동 발생기와 가요성 외접 기어 사이의 접촉 면적을 증가시키고, 접촉 면적의 증가에 의해 파동 발생기가 강성 외부 기어 내에 장착된 후 프레팅 마모 현상이 개선되어, 동력 전달 효율을 향상시키고 지연 오차를 감소시킬 수 있다.
