Harmonic gearhead with strain-wave gearing challenges planetary gearheads

Nexen Group : 01 March, 2013  (New Product)
Nexen Group is showcasing diverse motion control products at Hannover Messe 2013, 8-12 April in Hannover, Germany, including its roller pinion system (RPS) and precision ring drive (PRD), together with the newest addition, the harmonic gearhead.
Harmonic gearhead with strain-wave gearing challenges planetary gearheads

The new harmonic hearhead uses the latest harmonic, strain wave gearing to provide a rigid, high-torque, true zero backlash gearhead. Designed to replace planetary gearheads, this patent-pending, gearing-forward design overlaps components and allows the gearing to be integrated into less than half the space needed for alternative technologies.

Nexen’s RPS features a unique roller pinion/toothed rack combination that delivers high-accuracy positioning with zero backlash to virtually eliminate cumulative error. Offered in five distinct models, the RPS is specifically designed to meet demanding industrial applications, with each offering 99 percent operation efficiency, low friction and minimal maintenance requirements.

The PRD features smooth, precise motion in indexing and rotary positioning applications. Reaching speeds of 300 rev/min and lasting for up to 60,000,000 revolutions, the PRD combines power, rigidity and durability and low energy costs in high performance applications.
