ISO 6336 Certified High-Precision Straight Spur Gear for Industrial Transmission Systems

1. Product Overview

2. Core Structural & Precision Advantages

• ISO 6336 Full Standard Compliance: All gear parameters including tooth profile accuracy, pitch error, runout tolerance and surface hardness strictly follow ISO 6336 international certification standards. The standardised tooth strength calculation and precision grading system guarantee consistent mechanical performance and interchangeability, supporting universal matching with international standard transmission parts.

• High-Precision Tooth Machining: Adopts professional gear hobbing, fine grinding and tooth profile correction processes, achieving high precision up to ISO 6–8 grade. The uniform and smooth tooth surface ensures tight meshing clearance, effectively reducing transmission backlash and improving positioning accuracy of mechanical systems.

• Optimized 20° Full-Depth Tooth Profile: Equipped with industry-standard 20° pressure angle full-depth teeth, featuring thickened tooth root structure and reasonable stress distribution. It significantly enhances bending resistance and contact fatigue strength, avoiding tooth breakage and wear failure under high-speed and heavy-load working conditions.

• Standardized Dimensional Uniformity: Strictly controlled pitch diameter, tooth spacing and concentricity errors ensure excellent coaxiality during high-speed rotation. The symmetrical straight-tooth structure produces no axial thrust during operation, reducing auxiliary load on bearings and shafts.

3. Premium Material & Industrial-Grade Craftsmanship

• High-Strength Alloy & Carbon Steel Materials: Optional 40Cr alloy steel, 20CrMnTi carburized steel and 45# carbon steel. The materials feature high rigidity, strong toughness and excellent wear resistance, fully meeting the mechanical strength requirements specified by ISO 6336 for industrial transmission gears.

• Professional Heat Treatment Process: Adopts integral quenching and tempering or tooth surface high-frequency quenching treatment. The tooth surface reaches high hardness while the gear core maintains good toughness, achieving perfect balance between wear resistance and impact resistance.

• Fine Surface Finishing: Precision grinding and deburring processes eliminate surface burrs and tool marks. The smooth tooth surface reduces meshing friction and abrasion, improving transmission efficiency and resisting long-term cyclic load fatigue.

• Strict Quality Calibration: Each batch of gears undergoes professional testing including gear precision detection, hardness test, metallographic analysis and strength verification to fully meet ISO 6336 standard indicators.

4. Key Performance & Operational Benefits

• Stable & Accurate Transmission: Standard tooth profile and ultra-low tolerance error ensure precise meshing, stable power transmission and small running jitter, which is ideal for precision transmission and positioning equipment requiring high accuracy.

• Excellent Load & Fatigue Resistance: In line with ISO 6336 gear strength design specifications, it can withstand long-term variable load and heavy-load operation, with strong resistance to contact fatigue and bending fracture.

• Low Vibration & Low Noise Operation: High-precision meshing fit reduces meshing impact and friction noise, effectively lowering equipment operating noise and improving the working environment of mechanical equipment.

• High Transmission Efficiency: Smooth tooth surface and reasonable tooth profile structure minimize sliding friction loss, with transmission efficiency up to 98% and above, saving equipment operating energy consumption.

• Strong Versatility & Interchangeability: Fully compliant with ISO international standards, it features strong universality, convenient assembly and replacement, and good compatibility with various standard industrial transmission components.
