Product Introduction
This product is the pinion gear, a core transmission component of ball mills, specifically designed to drive the rotation of the ball mill cylinder. As a crucial link in power transmission, the pinion gear meshes with the large gear, efficiently transmitting the motor's torque and speed to the mill body, ensuring stable material grinding operations. This series of products is widely used in ball mill equipment in industries such as cement, mining, metallurgy, and chemicals, serving as a vital foundational component for ensuring the continuous and efficient operation of grinding systems.
Product Advantages
- High Strength and Durability: Utilizing high-quality alloy steel materials (such as 35SiMn, 40CrMo, etc.), and undergoing precision forging and tempering, the gears possess excellent impact resistance and fatigue strength, effectively resisting wear and deformation during long-term heavy-load operation.
- High-Precision Transmission: Relying on advanced CNC gear hobbing equipment and a strict quality control system, the gear's tooth profile and pitch accuracy are guaranteed, achieving smooth meshing with the large gear, reducing transmission noise, improving transmission efficiency, and minimizing equipment vibration.
- Scientific Hardness Matching: The pinion tooth surface hardness (HRC45-55) is scientifically designed to be 30-50 HB higher than the large gear tooth surface hardness. This hardness gradient design effectively avoids scuffing, ensuring synchronized wear of the large and small gears during long-term operation and extending the service life of the entire transmission system.
- Flexible and Fast Supply: With mature processing lines and ample inventory, standard parts are readily available, and custom-made non-standard parts have short processing cycles (typically 5-7 days), enabling rapid response to customer needs and reducing downtime.
Product Technical Features
- Material Selection: The main body material uses high-performance alloy steels such as 35SiMn, ZG45# forged steel, or 40CrMo to ensure excellent mechanical properties and wear resistance.
- Processing Technology: The standard process flow is "quenching and tempering → gear hobbing → high-frequency quenching of the tooth surface." Quenching and tempering improves core toughness, while high-frequency quenching strengthens the tooth surface hardness, giving the gears both a strong and tough core and a wear-resistant surface.
- Hardness: The tooth surface hardness is controlled within the HRC45-55 range, with uniform hardened layer depth, ensuring resistance to pitting corrosion under high contact stress.
- Specifications: The module range covers 14 to 40 modules, and different tooth numbers, tooth widths, and internal hole specifications (such as 90-degree double keyways) can be customized to meet the needs of ball mills ranging from 1.2 meters to 2.4 meters and even larger.
- Structural Design: The structure can be optimized according to the specific operating conditions of the ball mill (dry/wet) to ensure tight fit with components such as shafts and bearings, and stable and reliable operation.
