The structural design of the excavator slewing gearbox is the key to its superior performance. The slewing gearbox is typically composed of components such as gears, bearings, housing, and hydraulic motor interfaces. Its internal gear transmission system is precisely designed and optimized to maintain stable transmission efficiency under high-load conditions. Gears are one of the core components of the slewing gearbox, and their meshing accuracy directly affects the noise level and transmission efficiency of the slewing gearbox. Modern slewing gearboxes usually employ helical gears or planetary gear designs, which not only enhance the load-bearing capacity of the gears but also effectively reduce noise and vibration during operation.
