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.

The bearing system is also a crucial part of the slewing gearbox. Bearings play a role in supporting and transmitting power within the slewing gearbox, and their performance directly impacts the smooth operation and service life of the slewing gearbox. Modern slewing gearboxes typically use high-precision rolling bearings or sliding bearings, which feature high load capacity, low friction coefficient, and long service life, ensuring stable performance under harsh working conditions. Additionally, to further extend the service life of the bearings, slewing gearboxes are equipped with advanced lubrication systems. These systems ensure that the bearings are adequately lubricated during operation, reducing friction and wear, thereby prolonging the bearings' lifespan.

The housing design of the slewing gearbox is also of great importance. The housing not only protects the internal gears and bearings but also needs to withstand high external loads and impact forces. Therefore, the housing of the slewing gearbox is usually made of high-strength cast iron or cast steel and undergoes precision machining and heat treatment processes to enhance its hardness and impact resistance. Moreover, the sealing performance of the housing is a critical consideration in the design. Modern slewing gearboxes often employ multi-layered sealing designs to effectively prevent external dust, mud, and moisture from entering the slewing gearbox, avoiding corrosion and damage to the gears and bearings.
