New gear unit series for high torques

Siemens Drive Technologies expands its FLENDER gear program with a gear unit series for up to 1.4 million newton-meters.

With its high torque range, the new gear units are especially suited for applications in the steel and cement industries, conveyor systems, and sugar production.

At this year’s Hannover Messe, Siemens is unveiling a new gear unit series for high torques of up to 1.4 million newton-meters (Nm). With this new addition, Siemens now offers gear unit series covering a torque range from 3,000 Nm to 1,400,000 Nm.

The gear units are available as spur gear and bevel spur gear versions with gear ratios from 1 to 450. The gear unit series features a modular design and is built entirely of standard components. This means that low-cost gear unit series are now also available for applications that were forced to use custom-built components due to high torque requirements.

The heavy industrial gears in the Flender series are offered as two to four-stage spur gear and bevel spur gear units, and for horizontal or vertical mounting positions. The high degree of standardization means that both gear and bevel spur gear versions can be installed with the same components and standard enclosures. Both versions also offer the same output shaft solutions for different output concepts.

The progressive ratio of sizes allows fine gradation in the high torque range. Special requirements are implemented by the use of standard components or custom solutions, but they are always based on the modular system. The heavy industrial gears may be used universally in all applications that require high torque, as in the steel and cement industries, conveying systems, and sugar production.

Im Focus: ILA 2018: Laser alternative to hexavalent chromium coating

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.

When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
