Product Description

The RHPH series gear unit, specifically the Harmonic Drive RHPH0137, is a compact precision gearbox designed for applications demanding high torque density and exceptional positioning accuracy. This model features a lightweight aluminum housing with multiple mounting interfaces, supporting direct integration into servo motors or robotic joints. It operates within a voltage range of 12-48V DC and functions reliably in temperatures from -20°C to +85°C. The RHPH0137 excels in industrial automation, aerospace, and medical equipment, offering near-zero backlash (<1 arcmin) and a torque capacity up to 15 Nm. While its Harmonic Drive technology ensures smooth motion and longevity, the unit requires precise lubrication management for optimal performance. Compatible with standard communication protocols like EtherCAT, it enables seamless connectivity with motion controllers. The compact design eliminates need for battery or screen integration, prioritizing space-sensitive installations. Detection distance adapts via modular feedback options. Key advantages include high reduction ratios (50:1 to 160:1) and 93% efficiency, though initial costs may exceed conventional gearboxes.
