ABSTRACT

A servo reducer includes a motor gear connected to a driving motor, a support
structure, a first-stage gear set, a first-stage shaft, a second-stage gear
set, a second-stage shaft, a third-stage gear set, a third-stage shaft, and an
output gear meshed with the third-stage gear set. The first-stage shaft, the
second-stage shaft, and the third-stage shaft are mounted on the support
structure. The first-stage gear set is mounted on the first-stage shaft and is
meshed with the motor gear. The second-stage gear set is mounted on the
second-stage shaft and is meshed with the first-stage gear set. The
third-stage gear set is mounted on the third-stage shaft and is meshed with
the second-stage gear set. When an external load exceeds an allowable limit of
a gear strength, external load energy is converted into friction heat between
the teeth and consumed, so no backlash is defined.
