Harmonic Drive AG

Harmonic Drive offers a complete range of products for demanding applications:
The compact design of the backlash-free Harmonic Drive component sets allows a space-saving integration directly into machines. The component sets are available in various sizes and in different variants.

Harmonic Drive Units consist of a gear component set, equipped with a high capacity output bearing, which are intended for integration into a machine.

The key element of Harmonic Drive gearboxes is a component set within a housing with a flange or shaft as output assembly.

The Harmonic Planetary Gears comprise three variants with different accuracy classes in order to fulfill the demands of applications requiring ratios smaller than 50:1.

Harmonic Drive servo motors, servo actuators and controllers, used in applications with demanding requirements, provide precision motion control and high torque capacity in a very compact package.

We offer customer-specific solutions in a variety of configurations for both linear and rotational motion.

Gearboxes
Harmonic Drive Gearboxes are based on the Harmonic Drive component sets and include an integrated output bearing. All Harmonic Drive Gearboxes benefit from the same advantages as the Harmonic Drive component sets and units zero backlash, excellent accuracy, compactness, high efficiency and long life. The integrated output bearing also provides a high tilting moment capacity as well as a high tilting stiffness. This usually makes an additional load carrying bearing unnecessary and allows for a cost-effective and compact design.

Harmonic Drive Gearboxes are delivered with lifetime grease lubrication and are thus maintenance- free. The improved performance characteristics of the latest generation Harmonic Drive gearing makes them well suited for highly dynamic applications.

PMG Series Gearboxes are available in two different versions with an input shaft or for direct connection to a customer motor. All PMG Gearboxes are supplied with an output shaft and integrated bearings.

CSF-Mini Gearboxes use the latest developments in Harmonic Drive gearing. This results in greatly increased load capacities together with reduced size and increased torsional stiffness. They are available in six versions for increased flexibility. The possible versions can be selected from options for the output, the input and the gearbox housing. The gearbox output is available as a flange or a shaft; the gearbox input is available with either a shaft or as a version for direct motor adaption and two housing formats are available.

All Harmonic Drive Gearboxes are manufactured with the quality and precision expected from Harmonic Drive products.

PMG Series
In the HDUC Series PMG a HDUC Component Set is combined with a housing and output shaft to provide an extremely short unit with small dimensions. The Harmonic Drive gearbox is available in both close coupled and input shaft versions. The gearboxes offer high accuracy and compact dimensions.

Advantages

  • High torque capacity
  • High positioning accuracy and repeatability
  • Compact design
  • High single stage ratios
  • High torsional stiffness
  • Zero backlash
  • High efficiency
  • Robust construction
  • Mounts easily to servomotors

CSF-Mini Series
The new CSF-Mini Series Gearboxes set new standards in their class concerning compactness, precision and performance.

In the CSF-Mini Series Gearboxes, HFUC component sets are used for the first time in standardised gearboxes. In comparison to HDUC component sets currently used in the mini series gearboxes, the HFUC component sets feature a shorter design, higher accuracy, higher torque capacity and improved torsional stiffness, whilst they are also able to accept higher maximum input speeds. In conjunction with the newly introduced 30:1 ratio, the CSF Gearboxes can be used with a comparatively high output speed.

A highly rigid four point flange bearing has been specifically developed for use on the output. Therefore the output element is available optionally with shaft or flange mounting. The input can be realised alternatively via a shaft or by a directly coupled motor.

Advantages

  • Very compact design
  • Backlash free gear with high torque capacity, increased speed limits and optimised torsional stiffness and accuracy
  • Four point high rigidity output bearing, with optional output shaft or flange
  • Flexible assembly options at the input and output
  • Very low weight, making them ideally suited for lightweight applications

HPG Series
By using a flexible ring-gear the planetary gears achieve a backlash of < 1 minute of arc without requiring an additional backlash adjustment mechanism. Until now highly accurate gears and / or an additional adjustment mechanism were necessary to minimize backlash. Tight gear engagement for conventional planetary gears leads to torque ripple and a worsening of noise and wear characteristics. To avoid this problem the new HPG series features a flexible internally toothed ring-gear, thereby exploiting many years of Harmonic Drive experience with thin-walled components. The flexible ring-gear ensures that backlash is minimized and that all planet gears share the load equally.

Advantages

  • Backlash less than 1 minute of arc
  • High moment stiffness
  • High efficiency
  • Repeatability better than 20 seconds of arc
  • Easy motor assembly
