What is the HB Series Industrial Gearbox?
The HB Series includes heavy-duty gear units with parallel shaft (H Series) or right-angle helical bevel (B Series) configurations. They are built for high-torque, high-power applications in industries like mining, cement, steel, cranes, and marine equipment, offering robust construction and modular design.
What are the primary applications for HB Series gearboxes?
They are used in heavy industries for equipment like conveyors, crushers, mixers, turbines, cranes, and marine drives. The B Series is ideal for right-angle setups in space-constrained applications, while the H Series suits straight-line power transmission.
What materials are used in HB Series gearboxes?
Housings are made of high-strength cast iron (e.g., HT250) or welded steel plates for vibration resistance. Gears are typically 20CrMo alloy steel, carbonitrided to HRC 58-62 for durability and wear resistance. Selection and Specifications
How do I choose the correct HB Series gearbox size and ratio?
Select based on motor power (kW), input speed (RPM), required output torque, and service factor (e.g., 1.25 for moderate loads, 1.75 for heavy/shock loads). The HB Series offers 1 to 4 reduction stages with ratios from 1.25:1 to 450:1. Sizes (e.g., 1-26) support up to 160 kW or higher. Check thermal capacity for ambient temperatures above 30°C using manufacturer catalogs.
What is the efficiency and noise level of HB Series gearboxes?
Efficiency exceeds 95% per stage due to profile-ground helical and lapped bevel gears. Noise levels are typically below 85 dB, ensuring stable and quiet operation even under heavy loads.
What mounting and output options are available?
Mounting options include horizontal, vertical, or flange-mounted configurations with a modular design for compact layouts. Output options include solid shafts (single/double), hollow shafts with keyway, spline, shrink disc, or flange for versatile installation.
What input configurations are supported?
Input options include keyed solid shafts, IEC-normalized motor flanges, or adaptors for seamless integration with various motor types.
What is the torque capacity of HB Series gearboxes?
They are designed for large-scale industrial applications, with torque capacities up to 950 kN·m, suitable for high-power motors in heavy machinery.
How often should HB Series gearboxes be maintained?
Inspect oil levels every 500 hours initially, then every 2,000-4,000 hours. Change lubricant (preferably synthetic for heavy duty) every 5,000-10,000 hours or annually. Check seals and gears for wear. Bearings typically last over 50,000 hours (L10 life) under normal conditions.
