the "Rotary reducer / rotary gearbox of XCMG XE470" may involve its technical specifications, structural characteristics, working principles, and application scenarios. Below is an overview of the possible specific content of the rotary reducer / rotary gearbox for the XCMG XE470 excavator, based on general knowledge of rotary reducers / rotary gearboxes for construction machinery.
Technical Specifications
• Model: Designed specifically for the XCMG XE470 excavator.
• Weight: Depending on the specific design, there may be a certain weight range to ensure sufficient strength and stability.
• Reduction Ratio: Determines the ratio between the output speed and the input speed to meet the requirements of the excavator's slewing action.
• Carrying Capacity: Capable of withstanding the huge torque and loads generated during the excavator's slewing process.
Structural Characteristics
• Gear System: Utilizes high-strength, wear-resistant gear materials, precision-machined and heat-treated to ensure gear mesh accuracy and durability.
• Bearings: Uses heavy-duty bearings capable of withstanding radial and axial loads during slewing, while maintaining smooth rotation.
• Oil Seals and Seals: Employs advanced sealing technology to prevent lubricant leakage and impurity ingress, ensuring long-term stable operation of the rotary reducer / rotary gearbox.
• Gearbox Housing: Made of high-quality cast iron or cast steel materials, precision-cast and machined to ensure the housing's strength and rigidity.
Working Principles
The rotary reducer / rotary gearbox receives power from the excavator through the input shaft, which is then reduced and transmitted through the gear system to the slewing platform, enabling the excavator's slewing action. During slewing, the gear system transmits torque through meshing, bearings support the loads, and oil seals and seals maintain the cleanliness and sealing of the lubricant.
Application Scenarios
The rotary reducer / rotary gearbox of the XCMG XE470 is primarily used on large excavators to meet the slewing needs of the excavator in complex working conditions. It is suitable for applications in mines, construction sites, ports, and other locations for earthmoving operations, material handling tasks, and more.
