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.
