Description
Application
Design
3
The BIPEX-S couplings described here are torsionally flexible claw couplings that are free of
torsional backlash and are available in various types and sizes. They are characterised by a
very compact design.
BIPEX-S couplings are fail-safe.
These instructions describe the assembly and operation of a BIPEX-S coupling arranged
horizontally with a shaft-hub connection made by a cylindrical or conical bore with a parallel
key or by various clamping connections. Please consult Flender if you want to use a different
type of installation.
BIPEX-S couplings are designed for use in all kinds of machines. They are primarily used in
drive units with torque transmission without any backlash and only low misalignment.
A BIPEX-S coupling consists of two hub parts that are connected to one another by a cam ring
made of an elastomer material. In the BHH-W type the hub parts are connected to one another
by two cam rings and a spacer.
The cam ring is fitted between the hub cams with a small amount of interference. The coupling
characteristic of zero backlash is based on this.
The hub parts are joined to the shaft by finished bores with a parallel key or various clamping
connections.
The diagrams show the various types with their constituent parts and their part numbers.

Tightening torques and widths A/F (Page 63)).
5.2.2 Plug-in assembly of the coupling halves
Note
As a result of the interference between the cams and the cam ring (20) an axial force is required
to insert the coupling parts axially. The axial force depends on the size of the coupling and the
Shore hardness of the cam ring (20). It increases again after insertion so that there is no
permanent stressing of the coupled units.
The assembly procedure depends on which type you wish to assemble.
● Plug-in assembly of types BNN, BGG, BCC, BHH, BKK and BCS (Page 28)
● Plug-in assembly of type BHH-W (Page 28)
5.2.2.1 Plug-in assembly of types BNN, BGG, BCC, BHH, BKK and BCS
Procedure
1. Push the cam ring (20) onto a coupling part.
2. Push the coupling halves together. When doing this, pay attention to the dimension S from

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. the bearings) to an unacceptable extent.
The misalignment values in operation result from the following:
● Misalignment due to assembly
Incorrect position due to a lack of precision when aligning
● Misalignment due to operation
Example: Load-related deformation, thermal expansion
You can minimise misalignment by aligning after assembly. A lower misalignment in the
coupling has the following advantages:
● Reduced wear of the elastomer components
Assembly
5.3 Aligning the coupling
● Reduced restoring forces
● Misalignment reserves for operation of the coupling
You can find the maximum permitted shaft misalignment values during operation in section
Shaft misalignment values during operation (Page 62).
5.3.2 Possible misalignment
The following types of misalignment can occur:
① Axial misalignment (ΔKa)
② Angular misalignment (ΔKw)
③ Radial misalignment (ΔKr)
