There are many ways to improve productivity in a servo system. For example, there is the possibility that you can shorten the production cycle time if you use a high-performance servo motor and an actuator.
What is a chance to bring out the servo system performance?
However, there are some points users are overlooking. It is the evolution of coupling technology that uses the linking of a motor and an actuator. In using standard coupling technology, you may not be getting optimal performance from your servo system.
The history of a coupling’s performance improvement
Generally, the couplings used for a servo system require flexibility and torsional rigidity. To fulfill these technical specifications, the Slit Coupling was used during the 1990s and then updated to Disk Coupling in the 2000s.
Around 2005, the servo motor with a higher speed response frequency appeared. There was a technological limit in regards to the shortening of the production cycle time even if we increase the coupling’s torsional rigidity.
What is the limit of torsional rigidity?
The cause is co-vibration. The increase of a coupling’s rigidity is insufficient to increase the rigidity throughout the whole servo system. Due to the high-speed response frequencies, the co-vibration of the Servo System cannot be avoided. So what can be done?
In 2007, NBK took the lead in the industry with the launching of the High-Gain Rubber Coupling. In 2013, it launched a new coupling, the “XG2,” with a capacity to achieve a much higher rigidity fo torsional rigidity and damping performance. With the XG2, you can increase your productivity and control of your Servo System through the high gain it offers compared to traditional couplings.
High-gain rubber couplings, the XG series, shorten the manufacturing time through the reduction of vibration even in high gain surroundings.
