Page 12: Intended Use
Safety instructions 2.2 Intended use ANSI Warning Warning - suspended load Warning - hand injuries Explanation regarding Machinery Directive 2006/42/EC The couplings described here are “components” in accordance with the Machinery Directive and do not require a declaration of incorporation. Protective clothing In addition to the generally prescribed personal protective equipment (safety shoes, overalls, helmet, etc.), also wear suitable safety gloves and safety goggles when handling the coupling. -
Page 13: General Warning Notices
● Do not make any modifications to the coupling that go beyond the permissible machining described in these instructions. This also applies to touch protection facilities. ● Only use original spare parts from Flender. Flender only accepts liability for original spare parts from Flender. - Page 14 Safety instructions 2.3 General warning notices BIPEX-S 3410en Operating Instructions 10/2017...

Page 23: Application Planning
Application planning Check the delivery for damage and for completeness. Report any damage and/or missing parts to Flender immediately. The coupling is delivered in individual parts and preassembled groups. Preassembled groups may not be dismantled. Transport of the coupling WARNING Severe personal injury due to improper transport Severe personal injury due to falling components or due to crushing. -
Page 24: Table 4-1 Types Of Preservative Agents For Long-Term Storage
Application planning 4.2 Storage of the coupling The coupling, unless not specifically ordered otherwise, is supplied with preservation and can be stored for up to 3 months. Note Information about storing the coupling ● Ensure that the storage room is dry (relative humidity < 65 %) and free of dust. ●... -
Page 25: Assembly
Assembly Assembly of the coupling comprises the following steps: ● Preparatory work (Page 25) ● Assembling the coupling (Page 26) ● Aligning the coupling (Page 29) WARNING Danger of injury due to bursting of the coupling If you do not observe the information stipulated here regarding assembly, this can lead to bursting of the coupling during operation. -

Assembly 5.2 Assembling the coupling 3. Put coupling part N (1) on the shaft. Note Coupling parts with cylindrical bore To make assembly easier, you can heat coupling part N (1) with cylindrical bore up to a maximum of 150 °C if required. Note when doing this the temperature range of the cam ring (20) (refer to section BIPEX-S cam ring (20) (Page 64)). -

Page 29: Aligning The Coupling
Assembly 5.3 Aligning the coupling Aligning the coupling 5.3.1 Purpose of alignment The shafts that are joined by the coupling are never on an ideal precise axis but have a certain amount of misalignment. Misalignment in the coupling leads to restoring forces that can stress adjacent machine parts (e.g. -
Page 30: Axial Misalignment
Assembly 5.3 Aligning the coupling NOTICE Property damage The specified permissible values for axial, angular and/or radial misalignment may not appear simultaneously. ● Halve the values for if axial, angular and/or radial misalignment if they appear simultaneously. 5.3.2.1 Axial misalignment Set the axial misalignment ΔKa to a value within the permissible tolerance range of dimension You can find the values for dimension S in section Speeds, geometry data and weights (Page 55). -
Page 31: Commissioning
Commissioning In order to ensure safe commissioning, carry out various tests prior to commissioning. Testing before commissioning WARNING Danger Overload conditions can occur during the commissioning of the coupling. The coupling can burst and metal parts can be flung out. There is a risk of fatal injury from flying fragments. ●... - Page 32 Commissioning BIPEX-S 3410en Operating Instructions 10/2017...

Page 33: Operation
Operation Normal operation of the coupling The coupling runs quietly and shock-free during normal operation. Faults - causes and rectification A form of behaviour which is different to normal operation is classed as a fault and has to be rectified immediately. Look out specifically for the following faults during coupling operation: ●... -
Page 34: Possible Faults
Operation 7.2 Faults - causes and rectification The faults and fault causes listed below only serve as an indication for troubleshooting. In the case of a complex system be sure to include all the system components in the search for the fault. -
Page 35: Possible Causes
Operation 7.2 Faults - causes and rectification Fault Cause Rectification Presence of vibration Coupling not suitable for the operating Use a coupling that is suitable for the conditions. operating conditions. Check the possible causes given in sec‐ tion Unsuitable coupling (Page 35). Incorrect assembly of the coupling. -
Page 36: Correcting Faults
Maintenance-related causes ● Stipulated maintenance intervals not adhered to. ● Spare parts that were used were not original spare parts from Flender. ● Flender spare parts that were used were old or damaged. ● Leak in the area of the coupling not detected so that chemically aggressive substances damage the coupling. -
Page 37: Correcting The Changed Alignment
Operation 7.2 Faults - causes and rectification 7.2.3.2 Correcting the changed alignment A changed alignment of the coupling during operation often occurs when the coupled machines shift towards one another. A cause of this can be loose foundation bolts. Procedure 1. - Page 38 Operation 7.2 Faults - causes and rectification BIPEX-S 3410en Operating Instructions 10/2017...

Servicing Maintenance intervals WARNING Danger of injury due to bursting of the coupling The coupling can burst if the maintenance intervals are not adhered to. There is a risk of fatal injury from flying fragments. ● Please observe all the stipulations concerning maintenance of the coupling in this section. WARNING Danger of injury due to bursting of the coupling The coupling can burst if the maximum permitted torsional backlash is exceeded. -
Page 40: Maximum Permissible Torsional Backlash
Servicing 8.2 Maximum permissible torsional backlash Note Shorter maintenance intervals If necessary, set shorter maintenance intervals depending on actual wear. Maximum permissible torsional backlash In order to calculate the torsional backlash, rotate one coupling part without applying torque up to the stop. Mark both of the coupling halves in the way shown in the diagram below. Turn the coupling part in the opposite direction up to the stop. -
