Construction machinery gears are core components of the transmission systems of equipment such as excavators, loaders, and cranes. They need to adapt to the complex construction environment with much dust, strong vibration, and large load fluctuations on construction sites, and their transmission reliability directly affects construction efficiency and equipment service life. Different from ordinary vehicle gears, construction machinery gears adopt a special configuration of reinforced tooth roots in structural design, combined with the design of widened tooth surfaces, to improve impact resistance and cope with frequent heavy-load starts and stops and instantaneous torque peaks during construction.

To adapt to diverse outdoor climates and working conditions, construction machinery gears are made of special alloy materials that are wear-resistant and corrosion-resistant. Their tooth surface performance is enhanced through multiple heat treatment processes, and at the same time, they are equipped with multi-layer sealing and protective structures to effectively block sediment and rainwater from invading the meshing parts and reduce the erosion of gears by harsh environments. According to the operation needs of different construction equipment, construction machinery gears will also be calibrated with differentiated parameters. For example, excavator gears focus on low-speed and high-torque transmission adaptation, while crane gears optimize smooth transmission characteristics to ensure precise matching with equipment functions.

In daily operation and maintenance, it is necessary to shorten the lubrication inspection cycle of construction machinery gears in combination with construction intensity, select special lubricating oil suitable for heavy-load working conditions, and regularly clean the dust and debris around the gearbox to check the integrity of seals. If abnormal noise or delayed power transmission is found in the transmission system, it is necessary to promptly investigate the meshing state and tooth surface wear of construction machinery gears to avoid the expansion of faults affecting the construction progress.
