Harmonic Drive UK will be exhibiting its range of high-precision HPN planetary gears at the Engineering Design Show at the Ricoh Arena in Coventry from October 21-22, 2015. Harmonic Drive can be found on stand number G50 in the Jaguar exhibition hall.

Now in its fourth year, the Engineering Design Show has tripled in size. With over 200 exhibitors and over 3500 visitors, the show provides a one-stop-shop for design engineers from a variety of industrial sectors, including automotive, aerospace, defence, medical and oil and gas, to network. The show will also include 20 keynote conference sessions as well as 30 free hands-on workshops.

Harmonic Drive has built a reputation over the last 40 years in developing servo actuator and high-precision gearing technology for military, defence, aerospace and robotic applications. At the exhibition, Harmonic Drive will showcase its range of planetary gears, with a particular focus on its HPN planetary gear range.

The HPN planetary gears are available in five sizes, with eight gear ratios from three to 31:1 and can transmit repeatable peak torques between nine and 752Nm. With a backlash of just five to seven arc minutes, the gear series offers a precision option for low-backlash applications including industrial automation, packaging and continuous production environments.

Graham Mackrell, managing director of Harmonic Drive explains: “The planetary gear gets its name from the way the outer gears are designed to rotate like planets around the central ‘sun’ gear. The entire assembly is then enclosed within a strong outer annular ring gear.

“We developed our HPN gear based on this planetary design because it offers a high torque capacity with low backlash, making it ideal for high-volume industrial applications where a competitively priced, accurate gear is required. As a result, the HPN delivers shorter machine cycle times, increasing productivity and reducing costs.”

Harmonic Drive’s application engineering team will be on hand to provide design engineers with product demonstrations for applications in the robotics, industrial automation, military and aerospace industries.
