Special Gear Units

With diverse applications and abundant experience, Hyosung Heavy Industries produces highly reliable products through experienced technical development personnel and various analysis, verification and testing.

Product Type

  • Wind Turbine Gear Unit

    Wind Turbine Gear Unit
    Hyosung has started to manufacture wind turbine gear units in response to customer demands for eco-friendly products. Since 2005, Hyosung began wind turbine gear unit production with the 750kW gear box. Hyosung has completed development of the 2MW gear box model and is currently developing the 1.65MW and the 5MW gear box.

    Characteristics

    • Easy maintenance
    • High gear ratio and power density
    • Water-pressure type damper (2MW)
    • Optimized design (gear, shaft, casing)
    • Highly durable gear with flexible pins (2MW)
  • Vertical Roller Mill Gear Unit

    Vertical Roller Mill Gear Unit
    Hyosung’s vertical roller mill gear unit technology is based on the know-how and technical capacity accumulated for the past 20 years and the technical agreement with RENK, and has been supplied to both domestic and international customers. Playing a key role in the crushing of coal, which is fuel for thermal power plants, and limestone for cement plants, the vertical roller mill gear unit has excellent durability against severe environments and is able to handle high loads. A temperature sensor is mounted on the vertical roller mill gear unit to monitor temperatures of the bearing and the oil. In addition, a combination of the planetary gear and the bevel gear enables Hyosung to design the reducer with a gear ratio of 20:1-40:1.

    Characteristics

    • Drives the bevel gear and the planetary gear in a straight line in two stages
    • Welded case without any cracks
    • Uses a shaft thrust bearing lubricated hydrostatically or hydrodynamically
    • Applies lubrication and cooling to the gearing and gear bearing according to the isolated oil supply system’s oil pressure.
  • Jacking System

    Jacking System
    Hyosung’s Jacking System gear box is a core product of the Jack Up Vessel. Its reduction of the gear ratio ranges from 100:1-20,000:1 or higher and is capable of performing a self-test of loads over 1,200 tons. Therefore, analysis of all parts and verification of the load test guarantees the best quality under heavy loads.

    Characteristics

    • Various gear reduction ratio: Ranging from 100:1-20,000:1 or higher
    • Self-test of loads over 1,200 tons
    • Quick delivery
    • High durability and excellent quality even with heavy loads
    • Certified by ABS and CCS
    • Various supply record since 2006 (440kips, 550kips, 660kips, 750kips, 1000kips)
  • Steel Mill Gear Unit

    Steel Mill Gear Unit
    Hyosung’s steel mill gear unit’s steel plate, coiler for steel sheet, 2-stage transmission for conveying the steel raw material, leveler for rolling, and mill for grinding the raw material have been verified through its global supply history and customer satisfaction.

    Characteristics

    • Forced lubrication
    • Mandrel shaft (coiler)
    • Easy maintenance using a bush (coiler)
    • Input drive power of two shafts or multi-shaft (leveler)
    • Gear shifting using hydraulic system (2-level shifter)
  • Marine Gear Unit

    Marine Gear Unit
    The marine gear units must have higher reliability and durability since their operational conditions are severe. Marine gear units are used for main propulsion, thrusters, dredger pumps, and generator gear boxes. The marine gear unit requires very complicated and high technology in the design and production stages. In addition, the units must guarantee semi-permanent lifetimes since replacement is not possible after installation.

    Characteristics

    • Design optimized for various customer requirements
    • Infrastructure for quick delivery and quality warranty
    • Easy operation and maintenance
    • High reliability and durability
  • Cooling Tower Gear Unit

    Cooling Tower Gear Unit
    Hyosung’s cooling tower gear is used to rotate the blade of the cooling tower. It must have water-proof functionality and it must endure long-term operations. In addition, the direction of the input shaft and the direction of the output shaft must be at right angles to each other.

    Characteristics

    • Protection class of IP55 or higher
    • Vertically-upward shaft
    • Input and output shafts are installed at a right angle
    • Uses a bevel gear
