CSF-Mini series: compact, lightweight and high-capacity gears

The CSF-Mini will be used in precise positioning applications, particularly in sectors like industrial robotics, factory automation and medical technology manufacturing. The gearboxes combine a high-precision Harmonic Drive HFUC-Mini Gear Unit with a compact four-point output bearing. This special design has been developed with a clear understanding of customer requirements and can be adapted to most third-party motors and motor manufacturers.

The new series enhances the range provided by Harmonic Drive UK and provides an innovative design for the increased demand for lightweight and compact gears. Compared with Harmonic Drive PMG gearboxes, the CSF-Mini gearboxes use a higher-capacity component set as well as an improved output shaft, and is mounted in a much smaller housing. As well as its small size and low weight, it also offers improved bearing capacity, zero backlash, high tilting stiffness and excellent repeatability.

Graham Mackrell, managing director of Harmonic Drive UK, explains: "The feedback we have had so far has been incredibly positive. Modern robotic systems require extremely compact precision gears that combine low weight and a high-capacity output bearing, resulting in robots that are versatile, accurate and have the ability to manage high payloads.

"The CSF-Mini has applications in all areas of modern mechanical engineering where precision positioning is required. Interestingly, it has practical applications in research institutions and hospitals, where robots are used for medical instrumentation control. The gear technology delivers the high accuracy and maximum rigidity required to achieve precise, fluid movements, all in a lightweight, compact design."

In addition, the CSF-Mini gearbox has a 'big brother' that will be launched in 2015. The CSF-LW is an additional line in Harmonic Drive's lightweight gearbox range that will complement the standard gear. The CSF-Mini offers a torque capacity of 0.2Nm up to 28Nm, whereas the larger CSF-LW is rated from 16Nm up to 2510Nm.

Mackrell continues: "The technological development of the robotics industry and its dynamic applications in the medical industry continue at a rapid pace. But we are ready for the challenge and more than capable of meeting the future needs of our customers."
