Q&A: My company manufactures high-speed metal forming machines. We have one application on a feed axis where we are encountering problems with the coupling...
For the past 30 years or more, designers
have paid due diligence to the electrical aspect of hazardous atmosphere equipment design, but have often ignored the mechanical side. In recent years, the mechanical aspects of ATEX design have increasingly come to light. Not only do electrical power transmission products, but also mechanical power transmission products need to comply with the ATEX directive.
In most cases, industrial power transmission calls for flexible rather than rigid couplings in order to forgive minor shaft misalignment. For that reason, this article will focus solely on the selection of flexible couplings.
Fairchild International, a U.S.-based manufacturer of underground mining equipment, has produced battery-powered DC scoops since the early 1980s. With 17 different models available, Fairchild offers a size to fit any coal mining operation, making it the leader in the industry.
A new solution has been developed around
the use of microprocessor-controlled
prostheses. Just like natural limbs, these
can react automatically, adapting to the
current situation.
Based on simulation methods and calculation tools developed by the Schaeffler Group and presented in the first part of this paper, three approaches regarding increased efficiency based on rolling bearings are presented.
