Komatsu Grader Dedicated Gear Rings 23B-15-12670

Core Features

Speed Reduction and Torque Increase & Power Transmission: Meets with the drive pinion (bevel gear/cylindrical gear), converting the high-speed, low-torque input from the gearbox into low-speed, high-torque (transmission ratio typically 4-6:1), meeting the traction requirements of graders for heavy-duty scraping, climbing, and soft ground operations.

Differential Adaptation and Driving Stability: If a differential ring gear is used, it works with the differential planetary gears to achieve differential rotation of the wheels on both sides, preventing wheel slippage during steering or on uneven surfaces, protecting the tires and transmission system, and improving the overall machine's passability.

Ensuring Operational Precision: High meshing precision reduces transmission impact and vibration, preventing the scraper and other working devices from shifting, ensuring the flatness and construction quality of leveling and slope repair operations.

Balanced Load Transmission: Uniform load distribution on the tooth surface, capable of withstanding instantaneous impact loads of 1.8-2.2 times the rated load, suitable for high-frequency heavy-duty operating conditions of construction machinery.

1. Factory-accurate fit

Manufactured according to Komatsu's original drawings, the tooth profile, pressure angle, mounting stop and other parameters are completely matched with the whole machine, and no additional adjustment is required during installation, avoiding the assembly error and early failure risk of non-original parts.

2.Excellence in Materials and Craftsmanship

Utilizing high-strength alloy steel of 42CrMo or 20CrMnTi, the teeth undergo forging, carburizing, quenching, and precision grinding, achieving a surface hardness of HRC58-62 and a root strength ≥1100MPa. This results in outstanding impact resistance, pitting resistance, and wear resistance.

Optimized tooth profile and helix angle design reduce meshing noise (≤85dB), achieving a transmission efficiency of 97%-98%, minimizing power loss, and improving fuel economy.

3.high adaptability to operating conditions

Engineered for rugged terrains with dust, water, high temperatures, and heavy loads, this model features factory-installed sealing to effectively block dust and mud, minimizing lubrication failure and corrosion risks. Its designed service life exceeds 12,000 hours.

1. Excellent reliability and maintainability

Low failure rate, reducing downtime for maintenance; good interchangeability with original parts, convenient maintenance and replacement, ensuring construction progress.

operating condition adaptation

Heavy-duty/mountainous operations: Prioritize original equipment manufacturer (OEM) parts or high-quality aftermarket parts to enhance impact and fatigue resistance.

Routine maintenance: Ensure materials and heat treatment meet standards to avoid tooth surface peeling, breakage, and other malfunctions caused by inferior parts.

Installation and Maintenance

During installation, adjust the meshing clearance (0.2-0.35mm) and contact spot according to the original manufacturer's specifications, and tighten the bolts to the specified torque (180-220N,m). Regularly check the oil level and quality of the bridge housing, and use Komatsu's designated GL-5 grade gear oil to extend the life of the gear ring.
