large FINE CYCLO speed reducER FOR robotic and automated processes requiring high reduction ratios

A new, large precision speed reduction gear that’s bringing increased efficiency to medium and large scale robotic and automated manufacturing processes requiring high speed-reduction ratios will be released at the forthcoming Drives and Controls Exhibition by Centa Transmissions.

The zero backlash FINE CYCLO F4CFS-UA 115, which is now available in the UK from Sumitomo precision product specialist Centa Transmissions, benefits from high positioning accuracy and is the only speed reducer of this high capacity that’s available anywhere in the world. It also has a very low propensity for error, even when working under maximum dynamic alternating loads.
Using the unique Cyclo principal, its innovative design features specially contoured cycloid disc lobes which enables the two-stage reduction gear to operate at very low vibration levels, with an optimal distribution of load forces. In the UA 115, the cycloid discs for the second stage gear are combined with four spur (involute) gears that operate as the first stage of a central toothed input shaft. Each spur gear is combined with an eccentric shaft which rotates two symmetric cycloid discs of the secondary drive stage.

The smooth distribution of forces within the gear unit and the high degree of overlap between the cycloid disc lobes and outer pins ensures that this large compact gear, with an outside diameter of 570mm, achieves a nominal torque up to 16,685 Nm and an acceleration torque of up to 30,000 Nm.

The dynamism provided by this new FINE CYCLO speed reducer, coupled with Centa’s vast expertise and versatility in designing and building dynamic and robust drive solutions, means that all types of precision positioning and automated manufacturing systems can work resiliently to the utmost proficiency for increased productivity. There are also four combination possibilities, which comprise coaxial, offset, right angle and large hollow bore designs, featuring planetary, involute and bevel-input pre-stage drive options.

The UA 115 also provides greater safety benefits as it can withstand up to five time its nominal torque in emergency stop situations, increasing operator safety whilst greatly reducing the propensity for damage to the manufactured or handled product.

The highly beneficial design and output characteristics of the new FINE CYCLO UA 115 mean that designers and engineers can confidently specify its use in all types of robotic, positioning and handling systems. And Centa’s skills in the integration of all types of Sumitomo precision gears and speed reducers, plus their own complementary range of flexible couplings and gearboxes, enable you to benefit from cutting edge drives of the highest accuracy and capability.
