Product Introduction

Spur Gear Working Principle & Mining Application
Spur gears operate through linear tooth contact between parallel shafts, enabling stable torque transfer with minimal backlash and high energy efficiency. Their straightforward geometry allows consistent load distribution, reduced frictional losses, and smooth engagement. High-precision AS1444 material combined with controlled heat treatment ensures excellent hardness stability and wear resistance.
In mining machinery-such as crushers, feeders, grinding mills, and belt conveyors-spur gears, pinion gears, rack gear drives, and other gear sets play a critical role in delivering heavy-load power transmission. Their ability to maintain alignment under shock loads makes them suitable for harsh mining conditions. Optimized tooth profile, controlled noise level, and compatibility with multiple spur gear types allow our gears to achieve superior operational reliability in continuous-duty mining environments.

Quality Control
Our quality system includes metallurgical validation, dimensional verification, and advanced defect detection. Each spur gear is inspected through multiple checkpoints to guarantee consistent hardness, precise geometries, and safe operation under heavy loads.
Magnetic Particle Testing (MT)
Detects micro-surface cracks to ensure tooth integrity under high-speed rotation.
Ultrasonic Testing (UT)
Identifies internal discontinuities to maintain metal density uniformity.
Hardness Verification
Confirms carburized layer depth and stable hardness gradient for long-term wear resistance.
Dimensional & Runout Control
Ensures strict tolerance adherence for smooth meshing.
Tooth Profile Inspection
Controls tooth deviation for reliable torque transmission.
Heat Treatment Integrity Check
Verifies quenching uniformity and tempering stability, preventing structural brittleness or deformation in heavy-load applications.
Gear Classification
Multiple types of gears for industrial applications
Packaging & Shipping
Our packaging system is engineered specifically for precision spur gears, ensuring dimensional safety and corrosion prevention during long-distance shipping. Each gear is individually oiled, wrapped in moisture-proof film, cushioned with anti-vibration material, and housed in fumigation-free plywood cases. Internal separators prevent metal-to-metal contact, while reinforced corner structures eliminate impact risks. All packages are labeled with item codes, heat treatment batch numbers, and traceability barcodes. This export-grade packaging fully protects small spur gears, large spur gears, helical gears, bevel gears, and other components from deformation, oxidation, or surface scratches.
