What are the advantages of screw gear compared to ordinary gears?

Screw Gear represents a fundamental change in power transmission design, solving some of the problems and challenges that traditional spur and helical gears struggle to address. As industrial machinery evolves toward compact, multi-axis configurations, Raydafon's precision-engineered screw gears offer unparalleled performance in non-parallel shaft applications. So, what are the advantages of screw gears over conventional gears?
