GFB Swing Drive with Output Torques up to 485 kNm
The hydrostatic swing gears of type MOBILEX GFB feature high performance and are ideal driving components that have proven their worth under arduous application conditions in the most unfavorable operating environments. Swing gears MOBILEX GFB are employed in excavators. Due to their extremely compact size they are best suited for direct mounting inside the equipment. Their design provides for ease of mounting and maintenance. The use of case-hardened gearwheels and nitrite annulus gears has resulted in low-noise running characteristics, and a consistently high manufacturing standard ensures excellent load carrying ability and outstanding operational reliability. The teeth of the gearwheels are optimized on the basis of L+S computer programs and yield highest safety margins. The drives feature an optimum total efficiency. The gear units described in this bulletin are subject to constant updating and technical advancement. To suit the specific needs of our customers with respect to dimensions and output further variants can be made available on request. We are prepared to give advice and provide assistance whenever needed, even in the project stage, to find the most appropriate application solution for you.
– High-duty planetary gearbox of modular construction
– Compact, space-saving, two-stage planetary gear design
– Robust bearing system absorbing the forces exerted by the ring gear
– Simple mounting, low-noise running, high efficiency
– Long service life, easy oil change
Application Conditions：Rexroth swing motor gearboxes have been designed for use at ambient temperatures ranging between -20° C and + 40° C. Environmental influences such as salt water, salty air, sand, dust, overpressure, heavy vibrations, extreme shocks and ambient temperatures, aggressive media and the like will impede the function of the product. To enable a safe design of the winch drive such conditions must be reported to the Factory.
Lubrication: The gear teeth 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 operating 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.
Brake: The standard supply scope includes a spring-loaded, hydraulically released multiple-disk parking brake arranged on the input side. The multiple-disk holding brake is not a service brake.
Hydraulic Motor: The gearbox is designed for direct flange attachment of a variable or fixed displacement motor (preferably a Rexroth hydraulic motor). If requested, the motor can be supplied along with the gearbox.
Gearbox Supply: Rexroth MOBILEX planetary gearboxes are delivered ready for installation, but without oil filling. The standard gearbox version comes with a priming coat of grey color 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 with TECTYL 502 C.
Weights, Oil Volumes, Dimensions: The specified weights are average figures. As far as oil volumes are concerned, swing motor 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 Notes: As prescribed by statutory provisions, all rotating parts must be protected by guards against accidental contact. Local safety regulations must be complied with. Commissioning and maintenance of the gearboxes must be performed in line with the instructions given in our operating manual.
