The inspection and maintenance of the sealing system are also essential aspects of slewing gearbox care. The sealing system of the slewing gearbox effectively prevents external dust, mud, and moisture from entering the interior, avoiding corrosion and damage to the gears and bearings. However, seals can age and wear over time, leading to a decline in sealing performance. Therefore, regularly inspecting the condition of the seals and promptly replacing aged or damaged seals are crucial for maintaining the sealing performance of the slewing gearbox. Moreover, for excavators operating under harsh conditions, the sealing system requires more frequent inspection and maintenance to prevent external contaminants from entering the slewing gearbox.

The gears and bearings of the slewing gearbox also require regular inspection and maintenance. Gears and bearings are the core components of the slewing gearbox, and their condition directly affects the performance and lifespan of the slewing gearbox. Regularly checking the meshing state of the gears and the operating condition of the bearings, and promptly addressing any abnormalities, can effectively prevent failures. For example, issues such as gear wear, pitting, and tooth breakage, as well as bearing wear, looseness, and abnormal noise, need to be addressed promptly. Additionally, for slewing gearboxes operating under high-load conditions, periodic disassembly and inspection are necessary to ensure the internal components are in good condition.
