Product Description

List of spare parts

The maintenance and care of the excavator slewing gearbox are crucial for ensuring its long-term stable operation. As a core component of the excavator, the slewing gearbox often operates in extremely harsh environments, enduring high loads, high impacts, and complex working conditions. Therefore, regular maintenance and care of the slewing gearbox can effectively extend its service life, reduce the incidence of failures, and improve the excavator's operational efficiency.

First and foremost, lubrication is the most critical aspect of slewing gearbox maintenance. The gears and bearings inside the slewing gearbox generate significant friction and heat during operation. Without adequate lubrication, the wear and tear on the gears and bearings can accelerate, potentially leading to failures. Therefore, regularly inspecting the lubrication system of the slewing gearbox and ensuring the quality and quantity of lubricating oil meet the requirements are key to maintenance. Modern slewing gearboxes are often equipped with centralized lubrication systems that automatically inject lubricating oil into the gears and bearings at regular intervals, greatly enhancing lubrication effectiveness and maintenance convenience. Additionally, the replacement cycle of the lubricating oil should be adjusted based on actual working conditions and usage frequency to ensure optimal lubrication performance.

Secondly, 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.
