Vadnais Heights, MN—Nexen Group, Inc. announced the industry’s shortest and most compact automation gearhead. The Nexen Harmonic Gearhead directly replaces much larger, high-ratio planetary gearheads utilizing the latest harmonic, strain wave gearing technology. In addition to its extremely short, compact size, the Harmonic Gearhead has numerous significant advantages over planetary gearing including high torque, true zero backlash and extremely precise positional accuracy.

Nexen’s patent-pending, 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.

The Harmonic Gearhead is available with the Nexen Roller Pinion System (RPS). The gearhead is integrated directly into the pinion without adding any length to the system, resulting in the only drive solution that maintains zero backlash from the driving motor shaft through to the driven load for both linear and rotary motion. This combination also adds significant simplicity saving the extensive time and expense of integrating a gearbox into the motion system; the user can simply bolt and go. Nexen’s RPS delivers high-accuracy positioning with zero backlash and virtually eliminates cumulative error. The RPS surpasses traditional rack and pinion systems with a unique roller pinion/rack combination that can be easily adapted to any application.
