HELI (CQCTRACK): Precision-Engineered Undercarriage Solutions for LIUGONG Excavators – Track Sprocket Assembly 46A0140 for CLG920/CLG922

As a vertically integrated manufacturer and global supplier of premium undercarriage systems, HELI (branded as CQCTRACK) delivers engineered replacement components that meet the rigorous demands of modern construction machinery. This document provides a comprehensive technical and commercial overview of our manufactured Track Sprocket Assembly, engineered as a direct replacement for LIUGONG OEM part number 46A0140, compatible with CLG920 and CLG922 crawler excavator models.

Product Technical Specification: Track Sprocket Assembly 46A0140

The sprocket is a mission-critical drive component within the crawler undercarriage system. It engages with the track chain links, transmitting power from the final drive to propel the machine. Premature sprocket wear directly leads to accelerated chain link wear and system inefficiency. Our 46A0140-compatible assembly is designed to restore and maintain optimal power transmission and system harmony.

• OEM Reference: LIUGONG 46A0140
• Compatible Machine Models: LIUGONG CLG920, LIUGONG CLG922 Crawler Excavators.
• Function: Final drive engagement, track propulsion, and track guidance.
• Critical Design Parameters: Tooth profile geometry, pitch diameter, hardness gradient, bore tolerance, and mounting bolt pattern.

Engineering Philosophy & Manufacturing Protocol

At HELI (CQCTRACK), we believe durability is engineered from the inside out. Our manufacturing process for the 46A0140 sprocket assembly is a multi-stage, quality-gated protocol.

Stage 1: Advanced Material Metallurgy
We begin with selected high-carbon, high-chromium alloy steel (e.g., SAE 4140/42CrMo grade or superior). This material is chosen for its excellent hardenability, ensuring we can develop a deep, consistent case hardness while maintaining a shock-absorbent core. Spectrographic analysis verifies material chemistry for every batch.

Stage 2: Precision Forging & Machining

• Forging: The sprocket blank is hot-forged to refine the grain structure, creating a continuous fiber flow that follows the tooth contour. This dramatically enhances fatigue strength and impact resistance compared to cast or cut-from-plate alternatives.
• CNC Machining: The forged blank undergoes multi-axis CNC machining. This ensures absolute precision in:
  • Tooth Profile: Each tooth is milled to the exact OEM-specified involute form and pitch, guaranteeing smooth engagement with the track chain and eliminating undue stress concentrations.
  • Bore & Hub Dimensions: Critical mounting surfaces are held to tight tolerances (IT7-IT8) for perfect alignment with the final drive output shaft, preventing eccentric wear and seal damage.
  • Bolt Holes & Pilot Surfaces: Machined for flawless mounting and concentricity.

Stage 3: Proprietary Heat Treatment
This is the core of our durability advantage. We employ a controlled carburizing and quenching process.

• Case Hardening: The component is exposed to a carbon-rich atmosphere at high temperature, allowing carbon to diffuse deeply into the surface layer.
• Quenching & Tempering: Rapid quenching creates an extremely hard, wear-resistant martensitic case (typically 55-60 HRC). A subsequent tempering cycle relieves internal stresses, providing optimal toughness and resistance to cracking.

Stage 4: Quality Assurance & Validation
Every batch is subject to a stringent inspection regime:

1. Dimensional Verification: CMM (Coordinate Measuring Machine) inspection of tooth profile, pitch, bore, and mounting features.
2. Hardness Testing: Rockwell and micro-hardness tests across the tooth flank, root, and core to validate the hardness gradient.
3. Non-Destructive Testing (NDT): Magnetic particle inspection for surface and sub-surface defects.
4. Performance Simulation: Run-in testing under load to verify smooth operation and seal integrity.

Competitive Advantages of Sourcing from HELI (CQCTRACK)

• Engineered for Synchronized Wear: Our sprockets are not made in isolation. Their tooth hardness and profile are engineered to match the wear characteristics of our track chains and other undercarriage components, promoting balanced system wear and extending overall undercarriage life.
• Total Cost of Ownership (TCO) Reduction: Superior metallurgy and heat treatment result in a slower wear rate, reducing machine downtime for changes and lowering cost-per-hour metrics significantly compared to inferior alternatives.
• Vertical Manufacturing Control: From raw material to finished goods, our in-house control ensures traceability, consistent quality, and supply chain reliability.
• Global Technical & Logistics Support: We provide comprehensive application data, installation guidance, and efficient logistics solutions for distributors and large-scale end-users worldwide.
