Functional Description Description ZF planetary gearboxes REDULUS GMH/GME are reliable drive components that have proved themselves successfully in a wide range of operating conditions. Long years of experience and a wide spectrum of products have made us specialists for all kinds of demands of industrial applications. Our quality management acc. to DIN EN ISO 9001 2000 constitutes the basis for a continuously high quality level. A dedicated team of R&D-, design- and sales engineers makes sure that customer requests are transferred into the best technical and economical solution. Our state-of-the-art...

Seals The standard scope of supply includes input- and output shaft sealed with radial shaft seal rings on replaceable wearing sleeves. Mounting position The gearboxes can be mounted in any position. However, the desired mounting position must be specified so that we can ensure proper lubrication. Bearings Gear wheels, planet carriers and shafts are carried exclusively in antifriction bearings. Scope of Supply ZF planetary gearboxes REDULUS are delivered ready for installation, but without oil filling. By default, an external paint coat (blue RAL 5015) is applied. The gearbox interior is protected...

Mechanical Review The continuous output torques shown in this table are based on the following conditions: • no-shock operation • up to five starts per hour with an admissible start-up factor Czul as high as 3-times the rated torque. The exact admissible start-up factor for a specific gearbox size and type can be seen from the table on page 11. In case of more frequent starts and higher start-up factors please contact our sales team.

Nominal thermal power limit P in kW Gearbox Size All figures are average values. We will be pleased to check your selection in questionable cases. The figures are valid for: • gearbox utilization 90 - 100 % • relative duty factor ED = 100 % • ambient temperature Ty = 20° C • max. oil temperature t , = 90° C • horizontal mounting position Heat transmission into the foundation has been assumed to be 10 %. For a gearbox with a direct-attached hydraulic motor, the thermal limit rating given in the table must be multiplied with a factor of 1.25 for two-staged and 1.2 for three-staged types. (Assumed:...
