Compact gearbox suits precise positioning

Targeting the demand for compact, lightweight and high capacity gears, Harmonic Drive has created the CSF-Mini series of gearboxes. Developed with versatile output options, the range opens up exciting applications in the robotics industry, where gearing technology is a hugely important factor.

The CSF-Mini will be used in precise positioning applications, particularly in sectors like 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 series aims to provide an innovative design solution to the increased demand for lightweight and compact gears. Compared to Harmonic Drive PMG gearboxes, the CSF-Mini uses a higher capacity component set, an improved output shaft, and is mounted in a much smaller housing. As well as its size and low weight, it also offers improved bearing capacity, zero backlash, high tilting stiffness and repeatability.

The CSF-Mini also has a 'big brother' to be launched next year. The CSF-LW is an additional line in Harmonic Drive's lightweight gearbox range which will complement the standard gear. The CSF-Mini offers a torque capacity of 0.2-28Nm, whereas the larger CSF-LW runs from 16-2510Nm.

“The feedback we've 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,” commented Graham Mackrell, Managing Director, Harmonic Drive UK. “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.”

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