The Harmonic Drive® Gear belongs to the group of strain wave gears. With smaller dimensions and a lower weight compared with conventional gear types, they are suitable for use in lighter and more compact applications and systems. Owing to their high reduction ratios and the fact that they consist of three basic components and have a coaxial orientation, strain wave gears can be easily integrated into existing applications.

The continuously increasing demands placed on servo drives require, among other things, perfect interaction between the motor, gears, motor feedback system and controller. To guarantee characteristics such as precision and dynamics, servo actuators from Harmonic Drive SE have a high degree of compatibility. The option to choose between a zero backlash strain wave gear and a low backlash planetary gear. The tilt resistant output bearing enables the direct attachment of high payloads without additional support and thus permits a simple and space saving design.

Requirements of the market for gears that support high speeds or low ratios often require the highest precision. Harmonic Planetary Gears meet this requirement. Due to their integrated motor connection with clamping element and motor flange, they allow easy mounting of servo motors. The special design with a flexible ring gear in the last stage ensures consistently high precision over the entire service life - we call this Permanent Precision®.

Faster cycle times, better quality and higher accuracy in conjunction with a high degree of customisation - these are the requirements of today’s customer. This is clearly demonstrated by the increasing demand for smaller production batch sizes.  However, it is also necessary to keep costs low and to reduce these by overall standardisation whilst continuing to develop and implement solutions within a defined time frame.
