Building Materials Crusher Gearbox

Features a precision gear meshing design to achieve over 95% transmission efficiency, effectively reducing energy loss; utilises high-quality alloy steel materials and heat treatment processes to ensure gear and bearing stability under heavy loads and impact conditions; supports multi-speed gear transmission and various installation methods (horizontal/vertical) to meet diverse industrial application requirements; Optimised tooth profile and housing structure reduce operational noise to below 85 decibels, meeting environmental standards; Sealed dust-proof design combined with a lubrication system ensures a service life of over 50,000 hours for critical components and extends maintenance intervals; Compatible with various power sources such as electric motors and hydraulic motors, widely applied in industries including metallurgy, mining, and material handling machinery. Its reliability, flexibility, and energy-saving characteristics make it a core component in industrial transmission systems, including Machine tool power gearboxes and petrochemical-specific gearboxes, which have strict requirements for precision and corrosion resistance.

 

Gear ratio range typically from 1.5 to 200; multi-stage gearboxes can achieve higher ratios to meet different speed requirements; Rated power ranges from 0.1 kW to 5,000 kW, with selection based on load conditions; heavy-duty applications (such as mining heavy-duty gearboxes and Metallurgical rolling mill gearboxes) require a safety factor to be accounted for; Input speed typically ranges from 750 to 3,000 rpm (matched with the motor), while output speed is adjusted according to the gear ratio; Torque capacity ranges from tens of Nm to millions of Nm, directly related to gear material and heat treatment processes; Efficiency ratings are ≥96% for single-stage drives, slightly lower for multi-stage drives, and approximately 70% to 90% for worm gear drive structures; Protection ratings typically range from IP55 to IP65, providing dust and water resistance; In high-temperature or corrosive environments, such as Chemical mixing gearboxes and Power Plant Conveying Gearboxes, special sealing materials are required; Installation configurations include horizontal or vertical output shafts, flange or base mounting, and compatibility with standard interfaces (e.g., IEC motor flanges); Lubrication methods include splash lubrication or forced circulation lubrication, with operating temperatures typically limited to -20°C to 120°C.

 

Standard Industrial Gearboxes are widely used in heavy industries such as metallurgical rolling mills (metallurgical rolling mill gearboxes), mining crushers (mining gearboxes), and lifting equipment, capable of withstanding high torque and impact loads; in material handling systems such as belt Conveyors , chain conveyors, and bucket elevators, they provide stable low-speed high-torque transmission; In the energy and power industry, wind turbine yaw/pitch systems and coal mills in thermal power plants (thermal power plant conveying gearboxes) rely on their ability to withstand harsh environments and long service life; in the chemical and marine sectors, mixing equipment (chemical mixing gearboxes), pump drives, and ship propulsion systems require corrosion-resistant seals and explosion-proof designs; Construction machinery such as excavators and concrete mixing plants require their compact structure and high power density; Machine Tool Cutting Gearboxes and precision drive systems in automated production lines rely on their low noise and precise speed control performance; in the infrastructure sector, elevator and rail transit drive systems emphasise their safety and maintenance-free characteristics. With modular design and reliability, standard Industrial Gearboxes have become a key component in industrial transmission, with applications spanning a wide range of fields from low-speed heavy-duty to high-speed precision.

 

When using standard industrial gearboxes (including special models such as machine tool power gearboxes or mining heavy-duty gearboxes), the following important matters must be strictly adhered to: First, operation must strictly follow the rated parameters to avoid overloading or overspeed operation, which may significantly shorten the service life or even cause safety accidents. Second, lubrication management is critical; oil levels and oil quality must be regularly checked, and lubricating oil must be replaced according to the manual specifications. Lubricants with appropriate viscosity grades must be selected based on different operating conditions and environmental temperatures. Third, during installation, alignment accuracy must be ensured, and the coupling offset must remain within the permissible range; otherwise, it may lead to increased vibration and premature bearing failure. Fourth, during operation, temperature and vibration levels must be monitored regularly; abnormal temperature increases or vibrations often indicate potential issues.
