Hedcon Worm Gear Reducer

Sumitomo Drive Technologies’ Hedcon Worm Gear Reducer is a specialized power transmission solution engineered specifically for applications characterized by heavy shock loads and high overhung loads. Unlike standard worm gear units that rely on bronze wheels, the Hedcon series utilizes a unique high-hardness steel worm wheel design. This innovative construction allows it to withstand shock loads up to 500% of the rated torque, making it exceptionally rugged and reliable in demanding environments where conventional reducers would fail.

The mechanical efficiency of the Hedcon series is a significant advancement over traditional worm drives. By employing a convex-concave tooth profile and optimizing the gear microgeometry, Sumitomo has minimized sliding friction between the worm and wheel. This results in a mechanical efficiency of up to 90%—a substantial improvement over the typical 40-60% efficiency found in standard worm gear reducers. This efficiency not only reduces energy consumption but also significantly lowers heat generation, allowing for continuous operation under heavy loads without the need for complex cooling systems.

Designed for maximum versatility and ease of installation, the Hedcon series features a hollow output shaft as standard. This design allows the reducer to be mounted directly onto the customer’s driven shaft, eliminating the need for additional couplings and reducing overall installation space. The series offers a wide range of reduction ratios, from 5:1 to 60:1, and is available in various mounting configurations, including foot-mounted, face-mounted, and shaft-mounted options.

Durability is further enhanced by the use of high-quality materials and robust sealing. The gears are crafted from premium alloy steel and undergo precise heat treatment to ensure maximum hardness and wear resistance. The housing is constructed from high-strength cast iron, providing excellent rigidity and protection against the elements. Backed by Sumitomo’s rigorous quality assurance, the Hedcon Worm Gear Reducer is the ideal choice for heavy-duty applications such as rolling mills, cranes, mixers, and mining equipment.
