The radio antenna in Dwingeloo is an iconic and historic structure that is still used daily for scientific research. Despite the age of the system, this remarkable installation places specific demands on maintenance and operational reliability.
Two biodegradable lubricants have now been successfully implemented for the lubrication of the installation. In addition to supplying these products, the project also included flushing the system, replacing the oil, and ensuring the responsible disposal of the used lubricant.
The antenna was designed and built by Werkspoor in 1965 and remains in operation today under the management of ASTRON (Netherlands Institute for Radio Astronomy). Maintenance is carried out in collaboration with CAMRAS, a volunteer organization dedicated to preserving and operating this unique installation.
Analysis and Optimization of the Drive Systems
The installation consists of several key components. These include the main drive with a right-angle gearbox and the pivot bearing, which together enable the antenna to rotate. In addition, two drive units mounted on top of the antenna are responsible for the vertical positioning of the dish.
Despite careful maintenance, questions remained regarding the quality of lubrication. Concerns were raised about whether the correct oil type was being used and to what extent contamination and wear were affecting performance. To investigate this further, a trend analysis was conducted based on periodic oil sampling.
The analysis revealed significant oil contamination and showed that the lubricant in use had an insufficient viscosity. In other words, the oil was too thin for this application.
