Product Introduction

This passive spur gear is a key power-transmission component, designed to mesh with a driving gear and transfer rotational force to a splined shaft (e.g., in transmission or transfer case assemblies).

Structure & Material

• Material: High-strength alloy steel, heat-treated (carburized & quenched) for high surface hardness and core toughness.

• Design: A spur gear with external teeth (for meshing with the driving gear) and internal splines (for connecting to a driven shaft). Precision-machined teeth ensure tight meshing tolerance.

Performance

• Power Transmission: Receives torque from the driving gear and transfers it to the connected splined shaft.

• Low-Noise Operation: Precision-machined teeth minimize meshing noise during high-speed rotation.

• Load Resistance: Withstands heavy torque loads in heavy-duty truck drivetrain systems.

Durability

• Heat-treated alloy steel resists wear, pitting, and deformation under extreme operating conditions.

• Carburized surface enhances tooth strength, extending service life.

Core Function

1. Torque Transfer: Transmits power from the driving gear to the driven shaft via internal splines.

2. Speed Regulation: Adjusts rotational speed (paired with the driving gear) in the drivetrain system.

3. Load Bearing: Handles high torque loads in transmission/transfer case assemblies.

Key Features and Benefits of the DZ9114320646 Passive Spur Gear

This driven spur gear isn’t just a chunk of hardened steel — it’s a precision-machined power-transmission component that plays a critical role in your vehicle’s drivetrain. Here’s what sets it apart:

• Precision Tooth Profile – Each tooth is cut to exact OEM specifications, ensuring optimal meshing with the mating driving gear and minimizing backlash noise.
• High-Grade Alloy Steel Construction – Manufactured from heat-treated alloy steel for superior hardness, wear resistance, and fatigue life under heavy loads.
• Splined Bore Interface – The internal spline is machined to tight tolerances, guaranteeing a secure, slip-free connection to the output shaft.
• Smooth Power Delivery – Designed to transmit rotational force evenly, reducing vibration and extending the service life of adjacent drivetrain components.
• Direct OEM Replacement – Drop-in fitment for Shacman trucks eliminates guesswork during installation, saving valuable workshop time.
• Factory-Direct Pricing – By cutting out distributors, Mettlead delivers this gear at a cost that improves your bottom line without compromising quality.

In other words, this passive spur gear balances durability, precision, and value — three qualities that matter most when you’re managing a fleet’s maintenance budget.

Technical Specifications

Below you’ll find the verified technical parameters for the DZ9114320646 Passive Spur Gear. These specs help confirm fitment and compatibility before you place your order.

Application Scenarios – Where Does This Gear Fit?

Understanding exactly where this component sits in the drivetrain helps you confirm it’s the right part for your repair or rebuild project. Here’s how the DZ9114320646 passive spur gear earns its keep:

• Compatible Vehicles: Shacman heavy-duty trucks (Shaanxi Automobile series), including models equipped with the corresponding transmission or transfer case assembly.
• Gear Function: Acts as the driven straight-tooth gear (从动直齿轮) that meshes with the driving gear in the gear train.
• Power Path: Receives rotational force from the active driving gear and transmits it through its splined bore to the connected output shaft, enabling downstream power delivery to axles or auxiliary systems.
• Typical Replacement Scenario: Worn tooth surfaces, excessive backlash, spline damage, or abnormal drivetrain noise during gear meshing engagement.

Frequently Asked Questions – Passive Spur Gear DZ9114320646

What is the exact function of the DZ9114320646 passive spur gear?

This gear serves as the driven (passive) straight-tooth gear in the gear mesh. It receives rotational force from the corresponding driving spur gear and transfers that torque through its internal spline to the output shaft. Essentially, it’s the link between the power source and the downstream drivetrain components in Shacman trucks.

How do I know if this passive spur gear fits my Shacman truck model?

The most reliable way is to match the OEM part number DZ9114320646 against your vehicle’s parts catalog or the number stamped on the existing gear you’re replacing. If you’re unsure, send us your VIN or assembly number and our technical team will verify compatibility for you.

What material is this spur gear made from, and how durable is it?

It’s manufactured from high-grade alloy steel that undergoes carburizing, quenching, and tempering. This heat-treatment process creates a hard tooth surface (HRC 58–62) that resists wear while maintaining a tough core that absorbs shock loads — giving you a long and reliable service life.

Can I visually inspect the gear teeth for wear before deciding to replace it?

Yes. Common signs that indicate replacement is needed include pitting on the tooth flanks, visible scoring or grooves, chipped tooth edges, and measurable backlash exceeding factory tolerances. Additionally, unusual grinding noise or vibration during gear engagement is a strong indicator of tooth surface degradation.

Does this gear require any special installation procedures?

Installation is straightforward — it’s a direct OEM-spec replacement. However, it’s important to inspect the mating driving gear and the splined shaft for wear before assembly. Installing a new passive gear against a badly worn driving gear or damaged spline will accelerate premature failure. Always apply the manufacturer-recommended lubricant during assembly.

What is the lead time and minimum order quantity?

Standard stock items typically ship within 3–7 business days. For larger bulk orders or custom-packaged requirements, lead time ranges from 15–30 days depending on quantity. There is no rigid minimum order — we work with both small workshop orders and large distributor volumes.
