POLY PKZ

The POLY shaft coupling is a torsionally flexible shaft coupling (safety coupling) for general mechanical engineering. It is axially pluggable and characterized by its excellent ability for compensating vibrations.Its special features are the flexible elements (bundles) in both coupling halves. Thanks to these individual elements it shears interrupting the power transmission with overload or wear of the elements.The POLY shaft coupling is particularly compact; that is why it is suitable for small shaft distance dimensions.

Function of shear type shaft couplings: The shear type POLY shaft coupling is particularly compact consisting of two hubs with cam and pocket elements arranged on the face on the circumference that are blindly plugged in axially.The individual elastomer sets are clamped in the tailor-made clearances of the coupling hubs transmitting the torque in this way.In case of overload or wear of the elastomers the power transmission is interrupted and the shaft coupling (safety coupling) shears off.
