1. 400 Years of Sumitomo Group History

The Sumitomo Group began more than 400 years ago when Masatomo Sumitomo opened a book and medicine store in the city of Kyoto, Japan.

Over the next 100 years, the Sumitomo family developed a leading presence in copper refining, which led to the family opening the Besshi copper mine.

From these beginnings, the Sumitomo group continued to grow and diversity to become one of the largest corporate groups in the world.

Even after 400 years, the Sumitomo family business spirit” is alive in each of the Sumitomo group companies. The core of the Sumitomo Group consists of 20 companies who share the Sumitomo Emblem as well as many common values and ideals.

3. More than 65 Years in Drive Technologies

Sumitomo Drive Technologies of Sumitomo Heavy Industriesbegan early in the 20th century.

In 1911, Sumitomo Machinery Co., Ltd. began manufacturingdirect-current electric motors(3.7kW) for the Besshi copper mine.

In the late 1930s’, the company formed a technical cooperationagreement with CYCLO Getriebebau Lorenz Braren KG of Germany. In 1939, Sumitomo Drive Technologies was born whenSumitomo Heavy Industries, Ltd. began to manufacture CYCLO Drives.

In 2003, Sumitomo Drive Technologies was implemented as aglobal group brand to bind all power transmission businesses ofthe world.

For more than 65 years, Sumitomo Drive Technologies continuesto lead the world in knowledge and innovation in power transmissionand control devices. Sumitomo Drive Technologies strives to be the“dependable partner” for our customers.

The first trial manufactured CYCLO Drive.

5. Features of Paramax Drives

Gear design is based on the AGMA standards with tooth modifications developed with computer technology. The resulting gearing has quieter operating characteristics, improved shock capacity, and longer life. Every PARAMAX 9000 series speed reducer is designed with precisely balanced gear combinations. All gearing is produced from vacuum degassed alloy steel.

Helical gears are produced with 25 normal pressure angle hobs at increased helix angles.This produces stronger and quieter gearing.

5. Features of Paramax Drives

Right-angle models allow direct motor mounting.This eliminates the need for coupling and simplifiesmotor installation, enabling more compact designs.

Driveunit Mounting

Horizontal Vertical Upright

Universal housing allows horizontal, vertical andupright mountings.

FEM analysis is used tomaximize housing strengthand rigidity, thereby ensuring correct gear alignment and noise reduction.

Housing Cooling

Depending upon the application, an additional cooling system may be required to increase the cooling efficiency. New designed fan and conduct air cowling gain larger thermal capacity.
