Flexible pin type couplings

They are failsafe and pluggable.

Buffer material and buffer geometry ensure an optimal balancing between resilience and restoring action as well as a good damping behavior.

Flexible pin type couplings are available in various series and designs.

The assignment of driving and drive side is arbitrary. Due to the assembly, the pin coupling has a small circumferential backlash. After the installation of the coupling, it is required to align the drive as precisely as possible because the extent of the displacements have a decisive influence on the service life as well as on the restoring forces and torques.

The permissible values specified on page 12 define the limit for the sum of alignment errors and operational displacements.

The operating temperature range is between -40°C-25°C ( If constructed of gray cast iron) and, depending on the buffer material, up to +100°C ( +120°C are possible for a short time).

Flexible pin type couplings exhibit progressive spring characteristics.

Buffer and bolts are interchangeable with those of earlier models. The selection of material for the pin and buffer components depends on the rotational speed. While gray cast iron can be used for low rotational speeds it is required to fall back on steel solutions in case of high speeds. Available as further constructive designs are welded designs. The constructive design (welded part or ductile iron) of steel is done by the manufacturer depending on the size.

Pins are made of flexible materials and placed in the holes on the edges of two hubs, which are connected by pins, hence the realization of torque transmission. Range : Maximum torque up to 2.0X10⁶Nm
