Developed for applications in conveyor belts as well as in compact wheel drives of autonomous logistics systems, FAULHABER’s robust DualGear provides high dynamics and precision in a compact design. The system, the company explains, offers a high-performance and economical solution for intralogistics environments. This is a versatile solution: Two
synchronous movements can be realised with one drive, reducing integration effort and optimising installation space and system costs. The new drive system combines
two high-performance partners in a compact unit – the powerful and dynamic brushless 32mm motor from the BX4 family; and two diameter- compliant mounted robust metal planetary gearheads from the GPT series at both ends of the motor. The BX4 base motor for the DualGear
combination is available in two motor lengths, 42mm and 68mm. This allows the drive system to be flexibly adapted to different performance and installation
space requirements. Hall sensors with sine/cosine output signals enable precise detection of the rotor position for exact commutation and positioning. In combination with an external motion controller, accurate positioning movement is possible, resulting in a drive system that combines torque and maximum accuracy with a compact design. The GPT planetary gearheads are
available with up to three stages, which enables exact dimensioning with respect to speed and torque requirements. In addition, the components have welded joints to ensure reliable and durable construction without the use of adhesives. According to the company, the
possibility of realising two synchronous, powerful movements with just one drive and a central control creates new approaches for efficient, simple system architectures, in the next generation of conveying and intralogistics systems.

gear units ensure smooth mixer operation
NORD DRIVESYSTEMS’ MAXXDRIVE industrial gear units have been specifically developed for mixers. The gear unit
series offers high output torques from 15 to 282 kNm and ensures smooth operation even under demanding operating conditions. The FEM-optimised and compact design
enables operation under ultimate external loads. For agitator applications, it is recommended to combine the
gear units with the SAFOMI-IEC adapter (SAFOMI = Sealless Adapter For Mixers). SAFOMI features an integrated oil expansion volume. Oil tanks and hoses as well as the leakage- and wear-prone radial shaft seal between the gear unit and IEC cylinder are no longer required. As a result, the SAFOMI- IEC adapter on the agitator drive enables greater operational reliability and reduced maintenance. Not only is the oil level and thus the required oil volume lower, but thanks to fewer attached components the installation space is also reduced. With two variants of its MAXXDRIVE right-angle gear units
with SAFOMI, NORD offers the wastewater industry a powerful drive alternative for brush aerators. As standard, the input stage is designed as an SAFOMI adapter. This makes the solution compact, low-wear and low-maintenance, and extends the operating times of the entire system. Two radial shaft seals on the output shaft offer additional protection, both externally against oil leakage and internally against aggressive substances that may damage the seal.

high precision gear units for surgical robots
With surgical robots, movements must be carried out with precision and exact repeatability while being safe around patients. Being compact and low weight, high-performance strain wave gears are ideally suited for the severe spatial constraints found in such environments. Nabtesco’s drive solutions meet the high
precision and safety requirements of the industry, from small and short gears, to digital gearboxes, to complete actuators. The company’s strain wave gears offer zero
backlash, excellent repeatability and high-torque capacity, and ensure transmission of the control movements to instruments and axles with no delay and with millimetre accuracy. The adjustable backdriving torque delivers controlled yielding and supports sensitive positioning. These have small dimensions and low weight, and enclosed designs enable effortless cleaning and sanitary conditions. Short gears are particularly interesting options for robot-assisted surgery.
Compared to conventional short-build strain wave gears, they deliver 120% power density and 140% life time at identical size. This creates additional

freedom for the development of compact and powerful robotics systems. Models with a hollow shaft make it possible to pass cables, hoses and power leads directly through the gear. Wherever applications call for a high level
of integration, actuators offer crucial benefits. Combining gear, motor, encoder, and an optional brake in one finely tuned unit, they ensure high functionality, effortless handling, and maximum compactness. For Emergency Stop situations, the strain
wave gears are designed for torque levels of up to 500% of the rated torque and offer a safety factor against failure of up to 1,500%. In the event of a malfunction, this level of protection helps keep patients and operating personnel safe. Additional safety is provided by the digital gearbox, which captures torque
variations with such precision that collisions can be detected ahead of time and movements can be stopped quickly.
