High torque heavy duty gearboxes are essential for powering long-distance conveyors, grinding mills, and bulk material handling systems in mining, cement, and steel industries. These units deliver reliable performance under continuous high-load conditions where downtime is extremely costly.
제품 개요
These gearboxes serve overland conveyors, ball mills, sag mills, and apron feeders. Core strengths include exceptional torque capacity, robust shock load handling, and the ability to operate continuously in dusty, high-temperature environments typical of mining and mineral processing plants.

작동 원리
Power from the electric motor is transmitted through a high-speed pinion into multiple reduction stages of helical or bevel-helical gears. Each stage increases torque while reducing output speed. The final low-speed shaft connects directly to the conveyor pulley or mill pinion. A reinforced housing and oversized bearings absorb the heavy starting torques and shock loads common in these applications.
핵심 이점
Handles peak starting torques of conveyors and mills without damage to gears or bearings.
Reinforced housing and optimized gear tooth profiles withstand sudden overloads from jammed material.
Designed for 24/7 operation with minimal maintenance in remote mining locations.
Precision ground gears achieve high efficiency, reducing energy consumption on long conveyors.
Foot, flange, and shaft-mounted options with torque arms simplify installation on existing structures.
Advanced sealing and forced lubrication systems allow longer periods between oil changes.
구조 및 재료 장인정신
Housings are fabricated from high-strength steel plate or heavy cast iron with internal ribbing for maximum rigidity. Gears are precision ground from case-hardened alloy steel. Large-diameter shafts and oversized spherical roller bearings handle combined radial and axial loads. Multiple labyrinth and lip seal stages provide excellent protection against abrasive dust.
일반적인 적용 시나리오
지상 컨베이어: Transmits power to the head pulley of long-distance belts transporting ore or coal from mine to processing plant. High torque handles full load starts reliably.
Ball and SAG Mills: Provides the massive starting torque and continuous low-speed power required for grinding operations in mineral processing.
Apron Feeders: Delivers controlled high torque to heavy apron feeders handling large lumps of material at the primary crusher discharge.
선택 가이드
Calculate required output torque including starting torque and service factor. Determine exact ratio needed for desired belt or mill speed. Consider mounting position, available space, and ambient conditions. Evaluate thermal capacity for continuous operation and confirm adequate lubrication system for remote sites. Discuss pulley diameter, belt tension, and any future capacity increases with the engineering team.

자주 묻는 질문
Q: What service factor is recommended for conveyor applications with frequent starts?
A: A minimum service factor of 1.8 to 2.0 is advised for conveyors with frequent loaded starts to account for high starting torque.
Q: How is lubrication handled on remote mining sites?
A: Forced lubrication with oil coolers and condition monitoring is standard. Oil analysis programs help extend change intervals.
Q: Can these gearboxes be supplied with condition monitoring sensors?
A: Yes. Vibration, temperature, and oil condition sensors can be factory-fitted for integration with plant SCADA systems.
Q: What is the typical lead time for a high torque unit?
A: Standard configurations are available in 8 to 12 weeks. Fully custom designs with special ratios or cooling systems require 14 to 18 weeks.
Q: Are spare parts readily available for older models?
A: Yes. Critical components including gears, bearings, and seals are stocked for both current and legacy high torque series.
사례 연구 – 엔지니어 현장 기록
