Ewellix is a global innovator and manufacturer of linear motion and actuation solutions. Today, our state-of-the-art linear solutions are designed to increase machine performance, maximise uptime, reduce maintenance, improve safety and save energy. We engineer solutions for industrial automation, medical equipment, mobile machinery, distribution and a wide range of other industrial applications.
The strength of this system would be massive. Planetary reduction gearbox systems are high torque output. Anyone know if this method has exploration/ core drilling applications?
Same function, higher power density or robustness/life expectancy. For applications requiring the smallest envelop-to-power ratio like robot mounted application, or for applications requiring huge lifetime, shockloads, highest reliability...
In fact, the planetary roller screw will act as a blender for most types of debris that would enter in it. You will get a polluted lubricant that would be detrimental on the long run, but very little risk of jamming or loss of recirculation device like for most ball screws
Seems like you've just taken the SKF video below and added new music and captions. Not very cool. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-IjlgeMeX-9Q.html&ab_channel=SKFGroup
Ewellix is the current name of the previously "SKF motion technologies" that was the linear motion branch of SKF that was divested in 2018. The factory and engineering remained the same, but changed name only.
You do have very nice rivet setters! Automated rivet setting is indeed one of the most important applications of this technology, allowing very compact actuator design for robot mount, and high tolerance to the extreme peak load you get at the end of the setting cycle!
It is a product made with automatic care function even if an installation error occurs at an angle of about 1 degree without any problem with the slide... It is a very good product.
In an industrial plant where I worked we had a couple machines that utilized these for precise movements via stepper motors, the rod diameter was approximately 13 mm x 72 mm in length and replacements were $1,800.00 in mid eighties dollars......
The technology isn't cheap, but you can get very big differences from an application to another, one size to another, with unit price for replacement or batches for OEM business...
Actually, you will find them in several high precision or heavy duty machining centers like vertical axis of gantry milling machines, but more on high precision grinding or broaching machines rather than on lathes 🙂 Applications where power density matters (at the end of robotic arms for example) will use them much more, though ;-)
