Component Set HDUR
The HDUR series component set is a flat gear system with very high torque density. It is characterised by a high gear reduction with a small axial construction length. Thanks to the two-row wave generator bearing and larger tooth mesh length, this series has the highest torque density of all Harmonic Drive® flat gears. The HDUR series functions in accordance with the strain wave gear principle and transmits rotational motion with high positioning and transmission precision.

The short axial length of the flat gears in the HDUR series enable maximum gear reduction in a very small construction space. Flat gears are ideal for use in dynamic servo systems and also as a differential unit for phase adjusters and speed controllers. Their ease of installation and maintenance free operation are further reasons for using this kind of gear in all fields of modern mechanical engineering. The gears in the HDUR series display increased torsional rigidity and peak torque levels. They represent the ideal drive solution for servo systems in robots as well as in handling and printing machines, which place high dynamic demands on the drive system. In the HDUR series of flat gears, an extra element is applied to the functional principle of the Harmonic Drive® strain wave gear. The dynamic spline (DS) is a hollow wheel with internal teeth - the same number of teeth as the flexspline. This component rotates in the same direction and at the same rotational speed as the flexspline and is used as an output element in speed reduction configurations. The dynamic spline differs from the circular spline by the chamfer in the external circumference.
