Strain wave gears with output bearing
In addition to the three basic components flex spline, circular spline and wave generator, the gear sets plus also have a tilt-resistant output bearing. This means they are ready for immediate installation and significantly reduce the design and assembly effort. The backlash-free gearboxes cover a wide range of torques and impress with the best performance data and maximum flexibility in terms of customization.
Optimum absorption of tilting moments
The gear sets plus are our tried-and-tested gearbox sets including a tilt-resistant output bearing. Cross roller bearings (CRB) are installed. These are able to absorb high tilting moments and thus ensure safe and reliable operation. The output bearings are perfectly matched to the respective gearbox set and contribute to the high load capacity of the strain wave gears. A coupling (Oldham coupling) is optionally available to compensate for any radial offset between the motor and gearbox input shaft.
