The modular precision-drive system by Schaeffler Technologies represents a significant advancement in industrial automation, particularly in robotics. Precision drives for industrial automation are typically configured from catalog products such as gearboxes, motors, encoders, brakes, and controllers. Integrating these components into a suitable housing or machine requires considerable customized design work. Pacific International Bearing Sales Inc offers Schaeffler modular precision drives, which can be designed and configured flexibly without the need for in-house development, culminating in an individually configured drive system.
The primary components of the modular precision-drive system include the high torque RT1 and Standard Torque RT2 precision strain wave gear series. These are available in various designs and are complemented by frameless motors tailored perfectly to the application, offering high power density. Additional options such as brakes, Hall sensors, encoders, temperature sensors, and controllers can be selected as required. The system also includes an integrated torque sensor for the RT1 precision strain wave gears, capable of handling demanding control tasks in automation.
The High Torque RT1 and Standard Torque RT2 precision strain wave gears have comparable sizes, but the RT1 variants offer 30% more torque and 40% longer life on average compared to the RT2. The Standard Torque RT2 series features a particularly extensive range of variants.
Configuration Options
Basic configuration
The Basic configuration provides a solid foundation with essential components for reliable and efficient operation. This setup includes High Torque RT1 or Standard Torque RT2 precision strain wave gears and a motor optimized for the transmission performance. This configuration is ideal for general industrial automation tasks that require dependable performance without extensive customization.
Classic configuration
Building upon the Basic configuration, the Classic configuration introduces more advanced components for enhanced precision and control. This level includes a ready-to-fit drive with an absolute encoder, providing precise position feedback essential for accurate positioning and control in various applications. Users can choose between a single-sided encoder setup, with the encoder at the gear input, or a double-sided setup, with encoders at both the gear input and output.
Key Features of Schaeffler’s Precision-Drive Systems
Schaeffler’s modular precision-drive systems, which are unique in their design to meet the demands of robotics and industrial automation, are available at PIB Sales. The following are the primary features that set these systems apart:
Modular design
The modular precision-drive systems are designed to be highly customizable. This flexibility allows users to design and configure drives according to their specific requirements without extensive design, development, and validation efforts. Schaeffler takes care of the customization process, providing a ready-to-use, individually configured drive system.
Integrated torque sensor
A standout feature of the High Torque RT1 gears is the option to include an integrated torque sensor using Sensotect thin-layer technology. This sensor provides accurate, stable measurements without affecting system rigidity, making it ideal for force-controlled processes such as grinding, polishing, and force feedback.
Tilt-resistant output bearings
Schaeffler exclusively uses tilt-resistant double-row angular contact ball bearings (XZU) in their precision strain wave gears. These bearings outperform crossed roller bearings of the same size by approximately 30% in terms of tilting rigidity, ensuring greater stability and reliability in various applications
