Advantages
High Load Capacity
The tooth surfaces are heat-treated to a hardness of HRC 50–60, capable of withstanding torque loads exceeding 5000 kN·m.
Precision Meshing Design
The pitch, addendum, and tooth profile are controlled to within ±0.05 mm, ensuring smooth meshing.
Long Wear Life
The tooth surface hardening and grinding treatment significantly improves wear resistance, extending service life by approximately 1.5–2 times that of conventional gears.
Stable Operation
Finite element analysis optimizes the gear structure, reducing stress concentration by 15–20%.
Machining process
Our gear manufacturing process usually includes forging, casting, machining, heat treatment, tooth surface finishing and so on.

FAQ
Q: What is the function of the Girth Gear and Pinion?
A: The girth gear and pinion form the core drive system of a mill, transferring torque from the motor to the mill shell, enabling smooth and efficient rotation.
Q: What materials are used for manufacturing the gears?
A: Both the girth gear and pinion are made of high-strength alloy steel or cast steel, heat-treated to HRC50–60, ensuring high wear resistance and load-bearing capacity.
Q: How is the precision of the gear ensured?
A: Tooth spacing, profile, and dimensions are machined to ±0.05 mm accuracy, ensuring smooth engagement, reducing vibration, and improving operational stability.
Q: What is the expected service life of these gears?
A: With hardened teeth and optimized design, the service life is 1.5–2 times longer than standard untreated gears, reducing downtime and maintenance costs.
Q: Can the gears be customized for different mills?
A: Yes. We can provide girth gears and pinions in various diameters, tooth counts, and segment designs to match your mill specifications and operating conditions.
