In the continuous heavy-duty transportation of heavy-duty trucks, the auxiliary box main shaft reduction gear, serving as the "last checkpoint" of power transmission, has its load capacity and wear resistance directly determining the vehicle's transmission efficiency and uptime.

With 15 years of expertise in heavy-duty truck transmissionsystems,XINGMULOULANintroducesthe 12JSDX240T-1707106-2 Auxiliary Box Main Shaft Reduction Gear, engineered tomilitary-grade standards to solve industry pain points such as gear noise, tooth breakage, and early wear in heavy-duty vehicles.

This product utilizes 20CrMnTiH high-quality carburizing alloy steel as the core blank material, renowned for its excellent hardenability and wear resistance. In terms of manufacturing, we employ a composite processing route of "gear hobbing - shaving - heat treatment - honing." Particularly in the heat treatment phase, we use imported German multi-chamber furnaces for controlledatmosphere carburizing and quenching. This ensures the tooth surface achieves high hardness while maintaining good toughness in the core, effectively resisting impact loads. The gear precision meets Grade 6 of the GB/T 10095-2001 standard, improving meshing smoothness by 30% compared to the industry average.

XINGMULOULAN adheres to the R&D philosophy of "Defining Performance by Material, Ensuring Longevity by Precision.

The 12JSDX240T-1707106-2 reduction gear has undergone rigorous bench fatigue testing and real-vehicle road testing. Its durability and reliability fully meet and often exceed OEM standards, making it the preferred replacement solution for numerous logistics companies and repair stations.

1.High-Strength Alloy Structure
Utilizes 20CrMnTiH alloy steel treated with carburizing and quenching. Surface hardness HRC58-62, core hardness HRC33-40, bending fatigue strength ≥1300MPa. Effectively resists tooth breakage caused by heavy impact loads.

2.Precision Profile-Shifted Tooth Design
Employs advanced tooth profile modification technology, optimizing tip relief and lead crowning. This increases the meshing contact pattern to over 90%, significantly reducing transmission noise and localized wear.

3.Full-Life Cycle Durability
Passed 1.5 million cycles of bench fatigue testing, simulating extreme conditions of heavy loads and frequent shifting. The gear shows no pitting or tooth breakage, with a lifespan 60% longer than standard products.

Q1: Does this reduction gear need to be replaced in pairs?
A1: Yes. Reduction gears are precision-meshing components. To ensure optimal backlash and contact pattern, we strongly recommend replacing them in pairs (both the drive and driven gears) to avoid meshing issues and noise caused by single-tooth wear.

Q2: What are the advantages of 20CrMnTiH material compared to standard 40Cr?
A2: 20CrMnTiH is a dedicated carburizing steel, offering significantly higher wear resistance and bending fatigue strength than quenched and tempered steel 40Cr. Under heavy impact loads, 20CrMnTiH is less prone to tooth breakage, and its surface hardness after carburizing is much higher, greatly improving wear resistance.

Q3: What should be noted during installation?
A3: Before installation, please measure the gear meshing clearance (standard backlash is usually 0.20-0.35mm). Also, check if the bearings are installed properly to avoid uneven wear due to shaft misalignment.

Q4: How are non-man-made quality issues handled during the warranty period?
A4: During the 12-month or 60,000 km warranty period (whichever comes first), if non-man-made quality issues (such as early pitting or tooth breakage) occur due to material or manufacturing processes, we will be responsible for a free replacement.

Q5: Do you support customization based on samples or drawings?
A5: Yes. We possess strong R&D and processing capabilities and support rapid prototyping and custom production based on customer-provided samples or drawings to meet different transmission modification needs.
