Harmonic Drive, a provider of precision motion control solutions, announced the release of its HPF series of hollow shaft gear units. Designed for heavy-duty industrial applications, these advanced gear units aim to offer high torque outputs and flexible installation options, making them ideal for use in demanding environments.

The HPF series hollow shaft gear units provide exceptional torque density and positional accuracy, making them suitable for a wide range of industrial applications including robotics, packaging and material handling. They feature a high torque output, with maximum continuous torque ratings up to 737.7 Foot Pounds Force (1000 Nm) and maximum peak torque ratings up to 1,102.94 Foot Pounds Force (1500 Nm).

The unique hollow shaft design allows for easy integration and installation in tight spaces, while also allowing for the passage of cables, hoses and other mechanical parts through the gear unit. Additionally, the hollow shaft design provides high torsional rigidity, making it suitable for high-speed applications.

Robotics Summit & Expo (May 10-11) returns to Boston

Andrew Zucker, a mechatronics engineer at Harmonic Drive, will be speaking at the Robotics Summit on May 10, 2023 at 2 PM ET. Zucker’s session, “Simplification of Advanced Motion Control Using Integrated Servo Drives,” will explore how to simplify the design of a robotic joint without compromising the features that normally come at the cost of bulky cabling and electronics, like performance, reliability or advanced motion control features. 

Built with state-of-the-art manufacturing processes and materials, the HPF series gear units are durable and reliable even in the most demanding environments. They also feature low backlash and low noise operation, making them ideal for applications where precision and quiet operation are a must.

Features include:

  • Hollow Shaft:  0.98″ to 1.26″ (25mm to 32mm)
  • Available in 2 Frame Sizes
  • Peak Torque: 73.53 Foot Pounds Force to 147.06 Foot Pounds Force (100Nm to 200Nm)
  • Ratio: 11:1
  • Backlash <3 arc-min
  • Extra-large Cross Roller Output Bearing
