Document Type and Number:
Japanese Patent JPH0648043
Kind Code:
B2
Abstract:
A harmonic drive motion transmitting mechanism having a housing encircling a circular spline within which is journalled a flexspline. The flexspline has an annular array of gear teeth thereon, which flexspline has an inner bore having a diameter defined as D. The circular spline also has an annular array of gear teeth mateable with those of the flexspline. A wave generator is mounted within the flexspline. The flexspline has a lip which extends longitudinally beyond the distal edge of its annular array of gear teeth by 10% to 40%D. The lip is of radially thickening dimensions from immediately adjacent the outer edge of the annular array of gear teeth thereon, and from a thickness of about 1%D up to a thickness of about 3%D at the distal edge of said flexspline, to minimize the skewing of the ellipsoidal deflection wave of the flexspline.
