Nexen harmonic gearhead

The Nexen compact harmonic gearhead directly replaces much larger, high-ratio planetary gearheads utilising the latest harmonic, strain wave gearing technology. In addition to its extremely short, compact size, the harmonic gearhead offers high torque, true zero backlash and extremely precise positional accuracy.

Nexen’s gearing-forward design overlaps components and allows the gearing to be integrated into the same plane as the bearing, resulting in an extremely short and rigid gearhead. This narrow, rigid design is combined with a large, rugged, crossed-roller output bearing, designed to handle all combinations of radial, axial and overturning moment loads in a single, compact envelope.

The harmonic gearhead can fit virtually any machine with key applications in products and machinery requiring a minimal footprint, such as machine tools, robots and robotic arms, medical equipment, rack and pinion systems and numerous general industrial positioning and motion control applications. It is also very easy to integrate with a standard ISO 9409 output flange that fits most standard components and end effectors.
