KTR POLY COUPLING PKZ

DESCRIPTION: POLY PKZ torsionally flexible, shear type shaft coupling Low-priced standard version, two-part and compact The torsionally flexible, shear type shaft coupling POLY PKZ is a low-priced standard version. The two-part POLY PKD shaft coupling allows for the separation of driving and driven side without axial shifting. The benefit is that the elastomers can be replaced when assembled. Apart from that driving and driven side can be radially assembled and disassembled.

POLY PKZ torsionally flexible, shear type shaft coupling

Low-priced standard version, two-part and compact

The torsionally flexible, shear type shaft coupling POLY PKZ is a low-priced standard version.

The two-part POLY PKD shaft coupling allows for the separation of driving and driven side without axial shifting.

The benefit is that the elastomers can be replaced when assembled. Apart from that driving and driven side can be radially assembled and disassembled.

Torsionally flexible, shear type shaft coupling
Short shaft distance dimension
Available with larger elastomers to offset the torsion clearance on request
Applications: general engineering
Vibration-damping
Axial, radial, angular compensation
Axial plug-in
Maintenance-free

The POLY PKZ shaft coupling is a torsionally flexible shaft coupling (safety coupling) for general engineering. It can be plugged in axially and is characterized by its excellent compensaion of vibrations.

Its special feature are flexible elements (packages) in both coupling halves. Thanks to the individual elements it has shear type properties interrupting the power transmission with overland or wear of elements.

The shaft coupling POLY is particularly compact. That is why it is suitable for small shaft distances.

Operation of shear type shaft couplings Poly PKZ

The shear type POLY shaft coupling has particularly short dimensions and consists of two hubs with cam and pocket elements positioned on the circumference on the face that are mounted by blind axial plug-in.

The individual elastomers clamp in the tailor-made free spaces of the coupling hubs transmitting the torque in this way.

With overload or wear of the elements the power transmission is interrupted and the shaft coupling (safety coupling) shears.

Component variation of shear type shaft couplings:

High adaptability with small variation by an optimally differentiated kit system. The POLY elements of one size can easily be combined with each other without problems. This allow to meet various shaft distances with the same basic component.
