HPF Hollow Shaft Gear Unit

The HPF Harmonic Planetary® gear unit delivers High-Torque and High-Accuracy with a Hollow Shaft design. The HPF Hollow Shaft Gear Unit incorporates continuous backlash compensation that ensures low backlash throughout the life of the gear. An extra-large Cross Roller bearing serves as the output flange and can directly support large loads with exceptionally high moment stiffness. The large coaxial hollow shaft allows cables, shafts, ball screws or lasers to pass directly through the axis of rotation.

Key Features:

• Hollow Shaft: 25mm to 32mm
• Available in 2 Frame Sizes
• Peak Torque: 100Nm to 200Nm
• Ratio: 11:1
• Backlash <3 arc-min
• Extra-large Cross Roller output bearing

When starting a new motion control project involving a gearhead, In-Position Technologies engineers start by reviewing the key requirements to determine the optimum gearhead type, gear ratio, and form factor for the job. They perform all necessary engineering calculations to make sure the system performs as required, within customer specification, and without unnecessary cost. They will also recommend the appropriate accessories that will best fit the application.  

To ensure a gearhead fits the customer’s requirements, In-Position Technologies engineers review:

• Gear Ratio
• Gear Geometry
• Backlash
• Efficiency
• Weight
• Maximum Input RPM
• Nominal Output Torque
• Maximum Acceleration Output Torque
• Emergency Stop Torque
• Axial Load
• Radial Load
• Gearhead inertia at input
• IP Rating

When ordering the HPF Hollow Shaft Gear Unit as a part of a full system, IP Tech engineers review the solution to ensure:

• All parts and accessories necessary for a complete working solution are included
• All components have been checked and verified to work together as a system
• The selected components will perform as required by the project specifications
