NORD MAXXDRIVE XD gear units

Lifting applications place special demands on the installation space for drives. With MAXXDRIVE XD, NORD Drivesystems says it has developed an industrial gear unit with increased centre distance that is suited to the U-shaped configuration of drive, motor and cable drum.

During development, the MAXXDRIVE XD’s housing was specially designed for lifting applications and optimised for downward loads. The elongated arrangement of gear stages also enables a mechanical tailor-made dimensioning of the gear unit with sufficient centre distance, thereby avoiding the common problem of overdimensioning.

NORD currently offers the MAXXDRIVE XD in five sizes with centre distances between 509 and 963 mm, and also in versions with three or four gear stages. Housing dimensions and centre distance are identical for the three- and four-axle versions. This enables users to standardise and reduce versions when constructing their cranes. Due to the three and four stage versions, MAXXDRIVE XD covers a wide speed range with a maximum nominal gear ratio of i=355. The constant torque across the whole speed ratio offers a high efficiency while in use.

For the MAXXDRIVE XD’s components, NORD is using standard parts from its range of industrial gear units, offering users a wide choice of options and short delivery times. Additionally, the housing is also available with an inspection cover, enabling a visual check of internal components without having to remove the gear unit.
