In part one of my series “How to secure bearings properly”, we learned how and why bearings move in their mounting holes and what we can do against it. If press-fit is not enough or not available in order to keep a bearing in place, you can do so by changing it´s shape. In this […]
The various influences that affect the lifespan of a plain bearing are relatively trivial. It´s easy to imagine that a truckload of fine dust is rather less helpful for a long bearing life. Also, that 500 ° C ambient temperature can cause difficulty in choosing the right lubricant, results in few raised eyebrows. And yet, often times […]
There is a saying among german conservative engineers going like this: “Wer Kunststoff kennt, nimmt Stahl”. “Those familiar with plastics use steel instead”. To be honest I didn’t hear this in quite a while now. But it´s still in the heads of many engineers. Even if they don´t know a word of german. In the […]
In episode two of this series, I showed you some options of how to secure bearings axially to keep them from moving out of housing holes. In this episode, I want to show you how to make an easy anti-rotation feature and why you would need one in the first place. Why would you need […]
robolink® is a joint kit system. The igus® standard robolink® solution is in black colour today. Today we ask ourselves if this is the right colour for the product. Or should it be more light? One discussed solution might be SILVER (see pic). Please give us your vote which arm you would prefer if you had the choice. […]
At the FAKUMA trade show, our supplier and partner DR. BOY (http://www.dr-boy.de/) presented an injection moulding process. The automated handling of the products is operated by a 4 DOF robolink® joint arm RL-D-RBT-5532-BC (igus standard product) together with a CPR control unit (http://cpr-roboter.de/produkte/igusrobot.html).
An interesting, unusual problem solution to the calculation of complicated Robolink® movements is offered by www.RoBo-mac.de The program, a Mathematical 3D joint Toolbox controls Direct and Inverse Kinematics, all parameter and measurements “of your robolink® arm” can become basic inputs of the calculation. The program tool not only calculates “Pick & Place” final positions, but also individual […]
ALBIS is an igus customer and supplier: https://www.albis.com/ At FAKUMA fair, they presented a very nice “demo plastic factory”, using our 4 DOF robolink® arm RL-D-RBT-3322-BC as manipulator. The complete project has been realised by the training workshop at Albis (“AZUBI” project). Very nice demonstration!
