Heavy-Duty Bevel Gear Set for Rock Drill Jumbo Differentials This drive and driven bevel gear set is engineered to transmit power in rock drill jumbo differentials, delivering reliable performance in extreme mining conditions. Its precision-machined design ensures smooth torque transfer between the differential and drive wheels, critical for vehicle mobility in rough terrain .
Technical Specifications & Design
Core Performance Traits:
High-Strength Construction: 20CrMnTi alloy steel with carburized quenching provides 1200MPa tensile strength, while the hardened tooth surface (HRC 58-62) resists wear in abrasive environments .
Precision Engineering: ISO 6 class accuracy (DIN 3962) with ground tooth surfaces (Ra 0.8μm) minimizes noise and vibration, reducing energy loss during operation .
Load Optimization: 25° pressure angle distributes contact stress evenly across teeth, enabling 500Nm torque transmission without premature failure .
Performance Advantages
Durability:
Anti-scuff coating reduces friction, extending service life by 50% compared to uncoated gears, as validated by 10,000-hour wear testing (ASTM G133) .
Balanced core hardness (HRC 30-35) ensures toughness to withstand impact loads during sudden direction changes .
Environmental Resilience:
Operates reliably from -30°C (cold underground mines) to +120°C (high-friction differential systems), maintaining mechanical properties across temperature extremes .
Applications
Rock Drill Jumbos: Integral to differential assemblies, facilitating power distribution to drive wheels in mining and tunneling operations.
Heavy-Duty Equipment: Compatible with other off-highway vehicle differentials requiring robust bevel gear sets.
