Driven by both policy and market demand, the development of industrial drones has been booming in recent years. Industrial drones are breaking the tradition and continuously expanding their application scenarios in the fields of logistics and transportation, industrial inspection, emergency rescue, environmental protection, etc., profoundly changing the operation methods and efficiency of many industries, with huge room for growth and promising prospects.
However, complex and harsh environments and harsh application conditions always affect the performance of bearings. Therefore, in order to realize the free take-off and landing and smooth flight of the UAV, there are still many tests.
Not long ago, a domestic aviation electrical manufacturer encountered the problem of "how to ensure bearing performance in a strong corrosive application environment" in the process of designing an unmanned helicopter. The unmanned helicopter is mainly used for marine exploration, so the bearings used must be able to cope with the highly acidic salt spray environment.
SKF took full advantage of its own localization advantages, and with years of experience accumulation and active innovation in the field of drones, it only took three months to provide a complete set of bearing samples, which greatly exceeded customer expectations:
Using the breakthrough special material super stainless steel VC444, the corrosion resistance is significantly improved, which greatly prolongs the service life of bearings and equipment, and reduces the overall cost of ownership in the life cycle of the drone; Completed the four-proof (acid salt spray proof, acid atmosphere proof, mould proof and damp heat proof) test in a third-party laboratory certified by CNAS to help this model meet the requirements of relevant industry standards, such as "GB/T 38924.7-2020 Civil Light Environmental test methods for small unmanned aerial vehicle systems", the test requirements for environments such as heat and humidity, corrosion, etc.
