"Users of our high-end gearboxes expect high reliability, especially in their seals," said Michael Schmidt, an expert in sealing technology at WITTENSTEIN. Reliable sealing is especially important for applications in the food sector. Low-backlash planetary gearboxes are frequently used in these cases because they fulfill high requirements for precision and dynamic characteristics particularly well. The motion sequences for creasing and closing milk cartons, for example, must be adjusted precisely to the filling process. The packaging must also be precisely positioned and not oscillate during individual stops. Fluids must not spill over during further transport. This must all take place under strict hygienic conditions at very high speeds. There is also the fact that only certain food-grade lubricants that contain only limited amounts of additives are permitted in these applications. Here as well, premium Simmerrings from Freudenberg Sealing Technologies guarantee much lower wear than standard FKM seals. As a result, their operating life is significantly longer.
Foundation for the Development of New Special Applications
"We are now taking advantage of our experience based on the field use of radial shaft seal rings – documented with the evaluation and forecasting software – to jointly develop special applications with WITTENSTEIN," said Erich Prem, product developer for industrial applications at Freudenberg Sealing Technologies. It is not just the productivity requirements that increase with the increasingly complex and technically demanding applications – but also the reliability of individual components. With other industries in mind, the partners are currently developing wear-resistant sealing solutions with substantially longer operating lives for gearboxes, many fewer disruptions and much reduced downtime.
