ABSTRACT

The present application relates to a novel harmonic reducer, a flexible gear
assembly, and a robot. The harmonic reducer device includes a rigid gear, a
flexible gear, a wave generator, and a torque transmission member. The wave
generator is positioned within the rigid gear, and the flexible gear is placed
between the rigid gear and the wave generator, such that the flexible gear is
deformed by the protrusions of the wave generator, such that the external gear
of the flexible gear, corresponding to the protrusions, is partially engaged
with the internal gear of the rigid gear. The input connection portion of the
torque transmission member is joined to the torque output portion of the
flexible gear, while the output connection portion of the torque transmission
member is connected to a fixed connector to transmit torque. The deformable
elastic portion of the torque transmission member is designed to deform
simultaneously with the flexible gear.
