Functional Description

DescriptionGFB planetary gearboxes are swing gears. They are suitable for

use in excavators and cranes of all types, in ship unloading

equipment, forestry equipment and in all applications where

accurate positioning is needed.

The drive consists of a two- or three-staged gearbox with an

integrated multi-disk brake, an output pinion as well as a motor.

The information provided in this catalogue serves to help you to

select the planetary gearbox best suited for your application. In

addition, our technical sales is available to you to provide advisory

services even at the project stage.

LubricationThe gearteeth and bearings are splash lubricated. Aside from

periodic oil changes, the drive units are maintenance-free. Oil

changes are easy to do. The oil brands recommended in the oper-

ating manual shall be exclusively used.

The change intervals for the relevant application conditions are

also given in the operating manual. The pinion-side antifriction

bearing of the output shaft is grease-lubricated for life.

Hydraulic MotorsThe gearbox is designed for direct flange attachment of a variable

or fixed displacement motor. If requested, the motor can be

supplied along with the gearbox.

Spring-applied multi-disk brakeThe standard supply scope includes a spring-loaded, hydraulically

released multi-disc arranged on the input side. This brake is not a

service brake.

Gearbox SupplyZF planetary gearboxes are delivered ready for installation, but

without oil filling. The standard gearbox version comes with a

priming coat of gray color (similar to RAL 7032) and is internally

protected with a temporary corrosion preventive that preserves

the gearbox for 24 months, if stored in a dry location.

External flanges, shaft extensions and mating faces are protected.

Mass, Oil Volumes, DimensionsThe specified mass are average figures. As far as oil volumes are

concerned, gearbox operators should rely on oil level readings

rather than specified oil volumes. Figures and dimensions are not

strictly binding. We reserve the right to make changes in line with

technical progress.

Further NotesAs prescribed by statutory provisions, all rotating parts must be

protected by guards against accidental contact. Local safety

regulations must be complied with. Commissioning and mainte-

nance of the gearboxes must be performed in line with the

instructions given in our operating manual.

Layout and Classification

Operating ConditionsThe gearboxes are designed for use at ambient temperatures of

between -20°C and +40°C. Environmental influences such as

salt water, salty air, sand, dust, pressure, heavy vibrations,

extreme shocks and ambient temperatures, aggressive fluids

and the like may affect the function of the gearbox. All such

conditions must be specified so that the gearbox can be

designed for safe operation.

Gearbox DesignThe gearbox design is based on many years of practical applica-

tion experience. The maximum output torques T2 max indicated

under technical data for crane applications relate to FEM Sec-

tion I, 3rd Edition and Section IX (FEM - Fédération Européene

de la Manutention), as well as DIN 15020, collective load class

L2, service and time category T5 corresponding to driver group

M5. The reference output speed is 25 revolutions per minute

maximum. If the swing gearbox is to be classified in another

driver group, the required output torque must be converted

using the K factor (see table).

This conversion gives you the maximum admissible output

torque for the new driver group selected. Wether or not the

chosen overall classification can be met will be determined by

our gear technology experts

.

Higher TorquesFor gearboxes transmitting higher torques than those indicated

in this product catalog, please contact us.

Gearbox Selection ▶ T2 = Output torque

▶ T2K = Corrected output torque

K factor according to device time category and collective

group given in the table.

T2K = T2 • K

▶ T2K of the gearbox to be selected must be ≤ T2 max (according

to this product catalog).

Spring applied multi-disk brake TBr sta. min = 1,3 • T2 (input torque)

The holding torque multiplies with the selected transmission

ratio.
