Precision Strain Wave Gears for High and Standard Torque Applications
Schaeffler has expanded its range of precision strain wave gears to accommodate a broader range of applications in its robotics portfolio, and is now offering two series for lightweight robots: RT1 for the high-torque range and RT2 for standard torque applications.
The RT1 precision strain wave gear for the high-torque range is currently offered in four sizes from 14 to 32, in the ratios 100 and 160, and for torques of 25 to almost 900 Nm.
- Application range optimally covered with two strain wave gear series
- Series RT1 for particularly compact articulated arms and higher than average loads
- Series RT2 with extensive range of variants for easy integration into the customer design
The RT2 strain wave gears cover around 80 percent of standard cobot applications. The series is available in five sizes from 14 to 32, in five ratios from 50 to 160, in variants with a hollow shaft and for direct attachment to the motor shaft, as a closed unit with seals, and as a component set. The RT1 gears are currently available in four sizes from 14 to 32, in ratios of 100 and 160, and for torques of 25 to almost 900 Nm. Thanks to the high torque density, RT1 strain wave gears permit particularly compact articulated arms for higher than average loads.
The RT2 precision strain wave gear for standard torque applications is available in five sizes from 14 to 32, in five ratios from 50 to 160, in variants with a hollow shaft and for direct attachment to the motor shaft, as a closed unit with seals, and as a component set.
Their low weight and compact design make them an ideal choice for use in cobots. The backlash-free and wear-resistant tooth system of the strain wave gears guarantees excellent positional accuracy over the entire operating life. In both series, the high tilting rigidity of Schaeffler's XZU double row angular contact needle roller bearings enable a cobot structure with considerably increased rigidity.
