WiCHMANN - The company Our oldest tradiion is called: Innovaion. WiCHMANN GmbH have commited themselves to uncondiional customer orientaion. Guaranteeing funcion of your cardanshat drives is the task to which we have dedicated ourselves for over 30 years. This relects our claim "Leistung, die bewegt". The meaning is "Power that keeps you moving". We have therefore created one of the most capable organisaions in this ield of manufacture and repair of cardanshats for commercial vehicles and industrial plants with our Cardan Service Network (CSN). We are one of the most capable organisaion on the ield of manufacture and repair of cardanshats for industrial plants and commercial vehicles. We posses one of the largest warehouse of machinable inish-worked components worldwide. Together with our component employees, we make an internaional contribuion towards reducing breakdowns and machine downimes to a minimum. We create customer saisfacion via smooth communicaion routes, fast requirements analyses and secure problem soluions. All roads lead to the head oice in Osnabrueck.

2.2 Length compensaion – spline designs WiCHMANN ofers 2 diferent spline types of length compensaions. The involute proile is frequently used in small cardanshat sizes. The parallel side spline is used in heavy duty shats. On requirement we are able to ofer this spline for other sizes. Following advantages can be obtained: Advantage · separated torque transmission and alignment · due to a large contact surface, you reach a lower surface pressure and axial forces. This leads to high fricion resistance and service life · opimal for smaller sizes, shortest delivery ime and a good price performance Spline design SAE spline Involute spline Conidence ©www.wichmann-os.de Chapter 2 Page 7 02/2014

WiCHMANN - On top 2.3 Lubricant Cardanshats for standard operaing condiions are greased at our factory with a lubricant based on a lithium-complex saponiicaion. For operaion under heavy loads, as for example in rolling mill applicaions or in crusher drives, the use of a special lubricant with reacion-eicient addiives is recommended. These form a ani-wear coaing between the contact surfaces in case of high surface pressures and oscillatory movements in the U-joint. The service life can be considerably increased. Though test bench experiments, accompanied by WiCHMANN, it was determined that the fricion coeicient is thereby reduced by 25% for an axial displacement. This results in a signiicant reducion of the bearing loads of connected assemblies and a wearing of the tooth lanks. Both lubricants are compaible and mixable with each other.

WiCHMANN - On top Economical & fast. 3. Service concepts 3.1 Repair service Even with correct dimensioning and opimal maintenance, component failure in the U-joint is sill possible ater exceeding the bearing life, which can cause a considerable damage within the facility. For this reason, we recommend the prevenive replacement of the relevant components. Component failure can also be caused by unpredicted overloading. In order to guarantee professional workmanship, we recommend that the components be checked and repaired by our qualiied personnel. The punctual renewal of defecive components reduces maintenance costs. · Quality control · Warranty on renewed components · Coordinated pick-up service · Reassembly incl. replacement of defective components · Balancing report · Paint · Visual examination · Disassembly · Inspection · Inspection report ©www.wichmann-os.de Chapter 2 Page 10 02/2014

6. Length deiniion The working length EBL of your cardanshat deines the distance between the drive and output units and the values of changes in length occurring during operaion or at standsill. Cardanshats without length compensaion have a constant length L1 corresponding to the working length. L2 L1 EBLmax L1 = compressed length L2 = maximum possible length compensaion EBLmax = maximum possible working length Opimal working length = EBLopt. = L1 + ½ L2 ©www.wichmann-os.de Chapter 5 Page 15 02/2014
