Swing Gearbox DH55 2101-9002 2101-9002A 2101-9002B 2101-9002C for excavator parts

The excavator slewing gearbox is one of the core components of an excavator, primarily responsible for enabling the rotation of the upper structure. It is driven by a hydraulic motor, which transmits power to the slewing bearing, allowing the excavator to rotate flexibly during operation. The design of the slewing gearbox directly impacts the operational precision and efficiency of the excavator, requiring features such as high load capacity, low noise, and long service life. Modern slewing gearboxes utilize high-strength materials and precision machining to ensure stable performance even under harsh working conditions.

Product Description

The excavator slewing gearbox is one of the most critical core components of an excavator, primarily responsible for enabling the rotation of the upper structure. Driven by a hydraulic motor, the slewing gearbox transmits power to the slewing bearing, allowing the excavator to rotate flexibly during operation and perform various complex tasks such as digging, loading, and unloading. The performance of the slewing gearbox directly determines the operational precision, efficiency, and overall stability of the excavator. Therefore, the design and manufacturing of the slewing gearbox must meet extremely high technical requirements, including high load capacity, low noise, long service life, and excellent impact resistance.

The working principle of the slewing gearbox is based on a gear transmission system. The power output by the hydraulic motor is transmitted through a set of gears to the slewing bearing, driving the upper structure of the excavator to achieve 360-degree rotation. During this process, the slewing gearbox must withstand significant radial and axial loads, especially when the excavator is performing heavy-duty operations. The gears and bearings inside the slewing gearbox are subjected to tremendous pressure. As a result, the internal gears of the slewing gearbox are typically made of high-strength alloy steel and undergo precise heat treatment processes to enhance their hardness and wear resistance. Additionally, the housing of the slewing gearbox is made of high-strength cast iron or cast steel to ensure structural stability under high-load conditions.
