Innovative Self-Aligning Bearingless Planetary Gear Drives for High-Performance Applications

SABP Transmission Technology, Inc., based in Lincoln Park, NJ, has developed a groundbreaking self-aligning, bearingless planetary gear drive system. This innovative design ensures internal load balancing, enhancing stability and performance. Six prototypes have been successfully tested, with ratings of up to 500HP, input speeds of 8,000 RPM, and gear ratios ranging from 7:1 to 20:1. Ideal for non-angle gear applications requiring speed changes of 6:1 or higher, the SABP system has been adopted in off-highway vehicles and helicopter gearboxes, showcasing its commercial viability across various sectors, including government and aerospace.
