Harmonic Drive

Winding Gears

Harmonic Drive winding gears are a customised planetary gear with particularly high reliability. This special planetary gear is driven via the planet carrier and comprises two sun gears and a double planetary gear. This version does not require a ring gear. The complete housing acts as the carrier (input element) and rotates with an operating speed of up to 3000 rpm. This dynamically balanced system must exhibit low backlash and operate reliably in 24 hour/day use. The winding gears are applied in stator winding machines for electrical motors. Using the central hollow shaft the wire for the stator is passed between the planet gears.
