H/B series Parallel Shaft industrial gearbox

The HB Industrial Gearbox is a heavy-duty industrial transmission gearbox engineered for reliable power reduction and torque transmission in demanding industrial environments. Designed on a modular platform, this Industry Gearbox supports different shaft layouts including parallel and right angle configurations, and can be installed horizontally, vertically, or with torque-arm support. Precision machined gears undergo carburizing, quenching, and grinding processes to ensure high strength, low noise, and stable performance. With wide reduction ratio and power coverage, the HB series industrial gearbox is suitable for conveyors, crushers, mixers, and heavy machinery where durability and efficiency are paramount.

Product Advantages


Modular Heavy-Duty Design for Versatile Industrial Use


The HB Industrial Gearbox series features a universal design scheme that supports both parallel and orthogonal shaft configurations. Its modular structure reduces the number of parts while increasing specification options, enabling customization for specific industrial gearbox requirements such as hollow shaft outputs, flange outputs, and multiple mounting orientations.


High Power & Torque Capacity Across Wide Scope


HB series gearboxes cover large power and torque ranges suitable for industrial applications: torque up to 900 kN·m, power ratings extending to several thousand kilowatts. This enables the Industry Gearbox to serve heavy conveyors, large mixers, and other high-load machinery with confidence.


 Advanced Gear Processing for Efficiency and Reliability


Gears in the HB industrial gearbox are manufactured from high-grade alloy steels with precision carburizing, quenching, and grinding. The advanced processing ensures high surface hardness and durability, leading to stable torque transmission, reduced wear, and improved operational efficiency under heavy load conditions.


 Noise Reduction and Thermal Management


The robust housing of this heavy-duty industrial gearbox incorporates a sound-absorbent design and enlarged surface area to improve heat dissipation and lower operational noise. Large fans and optimized airflow further assist in managing temperature rise during continuous heavy-duty operation.


Flexible Installation & Integration Options


Designed for flexibility, the HB Industrial Gearbox supports multiple installation modes (horizontal, vertical, swing base, torque arm), multiple input methods (motor flange, shaft) and output options (solid shaft, hollow shaft configuration), making integration straightforward in diverse industrial systems without requiring extensive mechanical redesign.



Application Scenarios


Heavy Conveyors and Material Handling


The HB Industrial Gearbox efficiently manages torque and speed reduction in long-run conveyor systems in mining, cement, and port logistics. Its heavy-duty design ensures low vibration and consistent performance under fluctuating loads, reducing maintenance cycles and improving throughput.


Metallurgical and Mining Equipment


In metallurgical presses, crushers, and mining hoists, this industrial gearbox handles high shock loads and continuous duty cycles. Its robust structure, thermal management, and noise-reduced operation enable prolonged uptime in tough environments with dust, vibration, and thermal stress.


Power Generation and Heavy Machinery


For mechanical drives in power plants, large pumps, and mechanical presses, the Industry Gearbox ensures reliable speed control and torque delivery. Its broad ratio range and flexible shaft configuration help match different motor inputs and mechanical load requirements.


Bulk Material Processing


In industries such as cement, chemical, and aggregate processing, the HB gearbox supports mixers, crushers, and pulverizers with stable performance. Its precision gears and robust housing maintain alignment and reduce downtime through effective temperature and noise control.




FAQ


Q1: How do I determine if the HB Industrial Gearbox is suitable for my application?


A1: Provide your rated input power (kW), desired output speed or transmission ratio, and load torque requirements. Our experts will assist in selecting the correct HB Industrial Gearbox model and configuration based on those parameters.


Q2: What installation orientations can this gearbox support?


A2: The HB series supports horizontal and vertical mounting, swing base, and torque arm installation methods. Multiple input/output shaft options (solid, hollow, spline, flange) allow integration into different shafts and drive layouts.


Q3: Can the gearbox operate continuously in heavy industrial environments?


A3: Yes. The HB Industrial Gearbox is designed for continuous duty with robust housing, advanced heat dissipation features, and precision gear processing to withstand high torque and thermal stress over extended operation.
