Function, Specifications, Materials, and Key Parameters of 81.35111.0021 Ring Gear Assembly
1. Function
The 81.35111.0021 ring gear assembly is a critical component in the planetary gear system of vehicle axles, primarily used in heavy-duty commercial vehicles like Shaanxi Automobile Group's Delong series. Its main functions include:
• Power Transmission: Transfers torque from the drive shaft to the wheels, enabling vehicle movement.
• Gear Reduction: Works in conjunction with planetary gears to reduce rotational speed and increase torque output, providing the necessary power for driving.
• Load Distribution: Distributes driving forces evenly across the wheels, enhancing vehicle stability and traction.
2. Specifications
• Part Number: 81.35111.0021
• Application: Specifically designed for Shaanxi Automobile Group's Delong series heavy-duty trucks, including models like M3000 and X3000.
• Type: Internal ring gear assembly for planetary gear systems, typically mounted within the axle housing.
• Configuration: Includes an internal ring gear with teeth, which meshes with planetary gears to transmit power.
3. Materials
• Ring Gear: Typically made of high-strength alloy steel, which provides excellent wear resistance, fatigue strength, and durability under heavy loads.
• Other Components: May include bearing surfaces, mounting flanges, and lubrication channels, which are often constructed from steel or cast iron for strength and reliability.
4. Key Parameters
• Module: The module of the gear teeth, which determines the size and pitch of the teeth.
• Number of Teeth: The total number of teeth on the internal ring gear, affecting the gear ratio and torque transmission.
• Tooth Profile: The shape of the gear teeth, which must be precisely machined to ensure smooth engagement with planetary gears.
• Pitch Diameter: The diameter of the pitch circle, a critical dimension for gear meshing.
• Face Width: The width of the gear teeth, influencing the load-carrying capacity of the gear.
• Hardness: The surface hardness of the ring gear, typically achieved through heat treatment processes like carburizing or nitriding, to enhance wear resistance.
• Tolerance: The manufacturing tolerances for key dimensions, ensuring proper fit and function within the planetary gear system.
5. English Terminology
• Ring Gear Assembly: Also referred to as an internal ring gear or planetary ring gear.
• Planetary Gear System: A gear system consisting of a central sun gear, planetary gears, and an internal ring gear, which provides gear reduction and torque multiplication.
• Torque Transmission: The process of transferring rotational force from the drive shaft to the wheels.
• Gear Reduction: The decrease in rotational speed and increase in torque output achieved through the gear system.
• Load Distribution: The even spreading of driving forces across the wheels to improve vehicle stability and traction.
