List of spare parts

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.
