Bosch Rexroth launches 'most powerful' hydraulic drive



Bosch Rexroth launches 'most powerful' hydraulic drive
After many years of research and development testing, Hägglunds CBM is a range of very large heavy-duty hydraulic motors that eliminate the need for gearboxes and provides direct drive for high torque applications like wind turbines.

The CBM delivers 50 per cent more torque, is 50 per cent lighter than its predecessor and places less weight on the drive shaft to provide the world’s highest torque-to-weight ratio.

In addition, the CBM delivers a number of unique operating advantages expected from a direct drive, including full torque from zero, protection from shock loads and four-quadrant operation.

"The drive not only handles heavier workloads, but also takes up less space and reduces weight on the drive shaft. This makes the new motor ideal for use on large bulk materials handling plant, like apron feeders and bucketwheel machines, through to heavy mixers, digesters and diffusers" said Brian Holmes, sales support manager for Bosch Rexroth.


"The motor’s reduced installation requirements, combined with the higher productivity it provides, can mean lower overall investment costs and increased long-term revenue."

"This allows Rexroth to provide the unique advantages of a hydraulic drive to a broader range of applications than ever before."

Installation is made due to the splined hollow shaft that eases the attachment to the driven shaft.

Direct retrofit kits are also available to make the upgrade of an existing motor quick and easy. The motor utilises the Hagglunds DU drive unit to provide infinitely variable speed along with accurate load control and fast response due to the low inertia. This coupled with the large range of displacements allows the user to select the right size for their application and to maximise the products efficiency.

excellent, a new approach for wind turbine applications. Lighter, and compact, might find implementation in industrial areas where high torques are required
