R+W Elastomer Couplings

Information

Axes of Misalignment


Lateral	Angular	Axial

Function

The equalizing element of the EK coupling is the elastomer insert.
It transmits torque without backlash or vibration.The elastomer
insert defines the characteristics of the entire drive system.

Backlash is eliminated by the press fit of the elastomer into the hubs.
Through variation of the Shore hardness of the elastomer insert,
the coupling system can be optimized for the ideal torsional characteristics.

Sizes 2 - 800

Shore hardness 98 A Shore hardness 64 Sh D Shore hardness 80 Sh A Shore hardness 65 Sh D Shore hardness 64 Sh D

Sizes 2500 - 9500

The coupling includes 5x elastomer segments

Specification

Description of the Elastomer Inserts

Type	Shore hardness	Color	Material	Relative damping (Ψ)		Temperature range		Features
A	98 Sh A	red	TPU		0.4 - 0.5		-30°C to +100°C	high damping
B	64 Sh D	green	TPU		0.3 - 0.45		-30°C to +120°C	high torsional stiffness
C	80 Sh A	yellow	TPU		0.3 - 0.4		-30°C to +100°C	very high damping
D*	65 Sh D	black	TPU		0.3 - 0.45		-10°C to +70°C	electrically conductive
E	64 Sh D	beige	Hytrel		0.3 - 0.45		-50°C to +150°C	temperature resistant

*The electrical conductivity of the elastomer material is to prevent the electrostatic charging of the elastomer coupling system, to reduce the risk of sparking in operation. ATEX technical data is available upon request.
The values of the relative damping were determined at 10 Hz and +20˚ C.
