An innovative enterprise in drive

technique

Jahnel-Kestermann

Since the early sixties, the company Jah-nel-Kestermann, formerly Jahnel and after 1981 Jahnel-Kestermann, has been one of the leading enterprises in technology for the drive technique. Operations underwa-ter and on board, loosening and transport of sand and stones � under most difficult conditions � around the world, Jahnel-Kestermann is your experienced partner for the drive technique. Decades of experience in the dredging field, up-to-date calculation programs and fabrication methods being optimal and re-lated to the products offer safety and grant reliability for your plants. Competent engi-neers advise you on site by planning and realization of your special drives. Our ex-periences are the result of decades of close cooperation with the famous ship-yards and engineering companies as well as the criticism by the great international companies. Therefore, already decades ago Jahnel-Kestermann had the task to develop cut-ter-head gearboxes and have had it up to the current Hard-Rock-Cutter-Suction Dredgers of highest power. These gear-boxes, designed for extreme load, have in-tegrated axial-thrust bearings for absorp-tion of the axial load from cutter head. Already in 1970 we delivered the propeller and pump gearbox for the ship �Humber River� � with a hopper capacity of 10,000 m³. This hopper dredger was a milestone in further development! Meanwhile, Jahnel-Kestermann has equipped a great variety of cutter-suction, cutter-wheel and hopper-suction dredgers with gearboxes and couplings � for opera-tion underwater and on board, and accord-ing to the regulations and standards of Classification Societies including ice class.

Jahnel-Kestermann�s highest priorities are special solutions for the customers, reli-ability of operation and our proverbial ser-vice. No wonder, that Jahnel-Kestermann gets orders to design and manufacture the pro-peller, generator, jet- and dredgepump gearboxes as well as cutter drives for the largest dredgers. In the field of offshore technique Ja)(Ke�s gearboxes are in operation for deep-sea cutter, pipe fitter and oil platforms. Great crane ships lift their loads by means of Ja)(Ke�s gearboxes. Many years of experience flow into tooth-ing design, selection of bearings, construc-tion of casing and sealing of high-stress gearboxes. We make a point of our ser-vice availability e. g. the inspection of ax-ial-thrust pads. Here, a check is possible without essential gearbox disassembly. Calculation methods according to the lat-est state of engineering, torsional-vibration simulations and FEM analysis have been executed in our workshop. Thus, construc-tional influences regarding torsional de-flection and stress concentration may be identified at a very early state. For Ja)(Ke�s engineers it is important to know not only the gearbox but also the complete ambient conditions, consequently, to know all working conditions of the vessel. We offer these experiences for the selec-tion of gearboxes and couplings of any kind.

Meanwhile, Jahnel-Kestermann has equipped a great variety of cutter-suction, cutter-wheel and hopper-suction dredgers with gearboxes and couplings � for opera-tion underwater and on board, and accord-ing to the regulations and standards of Classification Societies including ice class.

shafts The gearbox output shaft has a forged-on flange for connection to the propeller shaft. The shaft is bored with mounting face for c.p.p. oil distribution box. The gearbox input shaft with cylindrical shaft end is adapted to the flexible coupling. housing The gearbox casing is designed as torsion-proof welded steel construction, suitable for accepting the outer forces and leading them to the basement. The internal rips are optimized due to vibra-tional properties and carrying-off of heat. bearings Bearing types are dependent on selected gear type. The pinion shaft can be equipped either with roller or plain bearings while the PTO-shaft is normally fitted with roller bearings. The propeller thrust is absorbed via thrust bearing collar seated in axial thrust pads, completely surrounded by oil. The relevant flange is forged to the shaft. The thrust pads can be inspected and replaced via inspection cover without dismantling the gearbox casing. gearing The pinion is made of case hardened steel while the bull wheel can be made of case hardened or through hardened steel. The pinion and the wheel have single helical and precision-ground teeth with optimum corrections to ensure long lifetime and low structure born noise level. lubrication and control system Gearing and all bearing points are lubricated with forced oil by means of a mounted lubrication oil device. Oil circulating system is completely built-on, including stand-by pump. Monitoring system acc. to classification rules including switchboard and interface. clutch The input and PTO shaft can be equipped with hydraulic operated multi disc clutches. The clutch is operated and lubricated by the hydraulic system of the gearbox. soft clutch device miscellaneous Gearbox outside painting RAL 5010 or according to customer�s requirements.
