81.35612.0019 Ring Gear Support

Function, Specifications, Materials, and Key Parameters of 81.35612.0019 Ring Gear Carrier

1. Function

The 81.35612.0019 ring gear carrier serves as a critical support component in the planetary gear system of vehicle axles, typically found in heavy-duty commercial vehicles. Its main functions include:

• Supporting the Ring Gear: It holds the ring gear in place, ensuring proper alignment and engagement with the planetary gears.

• Transmitting Torque: It facilitates the transfer of torque from the drive shaft to the wheels through the gear system.

• Maintaining Gear Mesh: It ensures consistent and accurate gear meshing, which is essential for smooth power transmission and vehicle operation.

2. Specifications

• Part Number: 81.35612.0019

• Application: Designed for use in the axle systems of heavy-duty commercial vehicles, such as those manufactured by Shaanxi Automobile Group or other similar heavy-duty truck makers.

• Type: Internal ring gear carrier for planetary gear systems, typically integrated into the axle housing.

• Configuration: Includes a carrier body with mounting features for the ring gear, bearings, and possibly lubrication channels.

3. Materials

• Carrier Body: Typically constructed from high-strength cast iron or forged steel to withstand the high loads and stresses encountered in heavy-duty applications.

• Bearings and Bushings: May use high-quality alloy steels or bronze alloys for durability and wear resistance.

• Fasteners and Fittings: Constructed from steel or stainless steel to ensure secure attachment and corrosion resistance.

4. Key Parameters

• Dimensions: Overall size and mounting dimensions must match the specific axle design, including the diameter and width of the carrier, as well as the spacing and size of mounting holes.

• Load Capacity: The carrier must be designed to handle the maximum torque and load ratings of the vehicle's axle system.

• Weight: The weight of the carrier affects the overall weight distribution and fuel efficiency of the vehicle, so it is often optimized for strength-to-weight ratio.

• Tolerances: Manufacturing tolerances for key dimensions, such as the bore for the ring gear and the mounting surfaces, must be tightly controlled to ensure proper fit and function.

• Lubrication Requirements: The carrier may have specific lubrication requirements to ensure smooth operation and longevity of the gear system.

5. English Terminology

• Ring Gear Carrier: Also referred to as a ring gear housing or planetary carrier.

• 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.

• Load Capacity: The maximum torque and load that the carrier can withstand without failure.

• Tolerances: The allowable variations in dimensions from the specified nominal values, which are critical for ensuring proper fit and function of the components.
