Profile

For decades, Jahnel)(Kestermann has been an innovative company in the development and productionof gear units for all industrial applications. Constructive intelligence, readiness to invest, closecooperation with scientific institutes as well as the high standard of production and quality assurance arethe main reasons why Ja)(Ke is among one of the leading companies of the power transmissionengineering in Germany. The company was founded in 1910 and with its 250 employees an annualturnover of approx. 35,5 million has been realized in 2006.

Besides gear units made to catalogue, Ja)(Ke specializes above all in the custom -made or small-lotproduction of special gear units (max. unit weight now approx. 225 t). Another speciality are gear wheelswith a maximum outer diameter of 3000 mms in welded, casehardened and ground resp. hoppedexecution. Furtheron, gear wheels up to an outer diameter of 4500 mms, max. module 30 also doublehelical gearing and MAAG toothings up to a module 50 are part of the delivery program.

They are used in the following areas:

mining (e. g. crushers, haulage-, plough- and conveyor systems)

chemical industry (e. g. agitators, i. e. gear and agitator, mixers)

materials handling technology / open-pit mining (e. g. bucket wheels,

stockpile pick- ups, belt type spreaders, conveyor belts, hoisting gears,

clamping winches, )

rubber and plastics industry (e. g. extruders, mixers, calenders)

metallurgical industry (e. g. converters)

steel and iron industry (e. g. rolling mills, coilers, shears, saws)

shipbuilding (e. g. dredging: cutter heads, - wheels, winches)

cement industry (e. g. kilns, mills, levigating-, comminution-, briquetting plants)

water engineering industry (e. g. locks, vertical lift gates)

wind power industry

sugar industry (e. g. presses, minglers)

A well-trained service team is always ready to assist the customers over the world.

Our philosophy is to offer the optimum solution to the special requirements of the customers

Agitators

For more than 50 years, Jahnel-Kestermann constructs agitator drives and drives for the chemical,pharmaceutical and food industry. Based on this long-time experience there is a standard programme foragitator drives having agitator shaft diameters from 80 to 220 mms that is composed of fix componentsand is used preverably for new machines. Furtheron, there are many innovative driving solutions forshaft diameters up to 380 mms and shaft torques up to 318 kNm. Especially the agitator drives for thePolypropylene production according to the BASF procedure are to be accentuated.

Irrespective of the shaft diameter, all drives have the same construction principles:

- flexible element between motor and gearbox (motor coupling, belt drive)

- gearbox with integrated fix bearing for the agitator shaft

- agitator support with fix coupling between gearbox and agitator shaft, loose bearing andshaft sealing (stuffing box, mechanical seal etc.)

If a mechanical seal is used as shaft sealing, it can be mounted and removed without dismantling thedrive on all Jahnel-Kestermann drives. All necessary work steps are possible into an exactly definedremoving direction. The advantage for the plant designer is that the space around and above the vesselbottom can be used in an optimal manner.

Due to the different weights of mechanical seals for shafts from 80 to 380 mms shaft diameter, there aremechanical and hydraulical change devices. In order to keep the stand-still time for a sealing change aslow as possible for the end-user, Jahnel-Kestermann has developped a symbiosis between agitatorsupport and agitator gearbox. Thus, even changing of mechanical seals having a single weight of 1200

kgs is possible within one day.

Individual requirements by our customers as top- and bottom-drives, small mounting height of drive withseal change guarantee, high vessel pressures and extreme loads on the gearboxes can be realised byJahnel-Kestermann without any problems. In co-operation with the plant designer or end-user, wealways try to find the most elegant solution.

Another achievement of Jahnel-Kestermann is the design of drives and agitator supports with regard tothe axial and radial forces influencing the stirrer. For this, we use several calculation programmes andthe FEM analysis. On this basis, construction with optimised material use is possible. For the user ofdrive, this results in a high functionality at a small weight.

As the noise of a chemical plant is very relevant, the Jahnel-Kestermann drives are very silent. Forfulfilling this statement, the gearing is optimised by calculations and manufactured on a highmanufacturing level. The reached result is checked during a test run of gearbox under load on our testbench and documented by a test report.

We offer our knowledge of gearbox technology in connection with our mobile measuring technics asservice for evaluation of existing plants or for the preventive maintenance of our own drives as well asthose of other manufacturers. If damages at gearing or bearings of gearbox are found, we have thepossibility to deliver a replacement. This is, of course, also true for agitator drives of the first generation.
