4 Graessner Yesterday and Today Since mid of the fifties Graessner manufactures Spiral and Hypoid bevel gears on Gleason gear cutters. Quality and customer orientation, combined with many years of experience, proved the reputation, that Greassner gear sets are used in applications, where performance and reliability is dominating. YESTERDAY Beginning of the seventies Graessner set a standard with the cubic Universal gearbox, with ratios up to 5:1 and all faces machined. Mid of the seventies the Hypoid range was introduced. Ratios up to 10:1 in a single stage were a sensation at that time and are still extraordinary today. Beginning of the eighties Graessner presented the PowerGear right angle gearbox, with a performance density not beaten up to date. A specific developed gearing allows highest torque at extreme small dimensions. Mid of the eighties Graessner presented with the Bevel Helical gearbox again a novelty. Ratios up to 50:1 in only 2 stages, combined with extreme high torque and a backlash < 5 arcmin, were and are partly still unbeaten. Based on quality and extraordinary reliability Graessner products proved their exceptional performance in all industrial branches in any kind of application. This could only be achieved, by having the necessary core competence within the company. TODAY Today Graessner is an independent company. With new investments in machine park, EDP and organisation, Graessner attuned itself to the increased market requirements and is well prepared to support our customers in challenging applications. Based on the long standing experience Graessner started end of 1998 a new development push. PowerGear performance increase up to 15% DynaGear the world wide unique Servo bevel gearbox with ratios up to 15:1 in a single stage ValueGear the ultra flexible low cost gearbox for all branches of the machine building industry A top motivated team with many years of experience and creative new ideas, is the Graessner success key. We don't know tomorrow's challenges. But we know that we need continuous improvement to remain your competent future business partner. 4

Labyrinth- and Switch-/Reverse Gear Boxes Labyrinth gearboxes are ultra high performance spiral bevel

They are designed for all mounting positions and present the following advantages.

oil supply Efficiency nearly 100% Lowest possible temperature increase, even at high speed Low noise,

Switch and Reverse Gear Boxes are spiral bevel gear boxes, used to engage and disengage 90º-torque

5 Labyrinth- and Switch-/Reverse Gear Boxes Labyrinth gearboxes are ultra high performance spiral bevel gear boxes with a non-contact oil seal. They are designed for all mounting positions and present the following advantages. Fretting free oil seal Maintenance free Reliable without oil leakage Possible connection to external oil supply Efficiency nearly 100% Lowest possible temperature increase, even at high speed Low noise, low vibration, high transfer accuracy All shafts without key way, ready clamp or shrink fit joint Switch and Reverse Gear Boxes are spiral bevel gear boxes, used to engage and disengage 90º-torque transfer. Switch Gear Boxes engage or disengage the power train. Reverse Gear Boxes allow an additional change of the rotation direction. All gearboxes can only be operated at standstill. 5

Double gearbox with 2 ratios Sheet positioning gearbox for printing machines Special gearbox with 3 output shafts in 120º orientation Gearbox 40 FH in special execution, working as a high load milling main drive. The drive runs at a speed up to 6000 rpm. A specific designed forced lubrication and a specific gearing allow these performance data. 7

8 Design and development Draft design Production planning Production in various steps with intermediate inspection A bevel gear on its own is insignificant. Incorporated into a system, comprising the housing, shafts, flanges and especially the bearing system, the bevel gear can fulfil its task. And a system is always as strong as the weakest link.
