Datasheet EKH

Product catalog summary

Overview: The document provides technical specifications and installation instructions for the EKH series elastomer couplings, featuring a split-hub design that is plug-in, backlash-free, and made of stainless materials.

Specifications:

Design: Split-hub, plug-in, backlash-free, stainless.
Materials: Elastomer spider made of polyurethane; split-hubs made of high tensile aluminum.
Dimensions: Length dimensions follow DIN ISO 2768 cH standards.
Order Example: EKH 200 - D1 = 26 G6 D2 = 32 H6.

Installation Instructions:

The split-hub design allows for a backlash-free, force-fitted clamping connection with simple operation.
Misalignment errors between input and output shafts can be easily controlled and corrected.
For assembly, fixed hub halves are placed on shaft pegs, and loose hub pieces are screwed on.
Service does not require disassembly of drive and output units.
The distance between drive and output shafts must exceed dimension 'g'.

Technical Data:

Screws: ISO 4762 / 12.9 - coated.
Sizes and Properties: Various sizes from 15 to 2000 Nm, with specific hardness, moment of inertia, torsional stiffness, max shaft misalignment, lateral spring rate, and maximum speed (nmax) detailed in a table.

Key Data from Table:

Size 15: 15 Nm, 98 Sh-A, 0.03 kgm², 0.24 Nm/arcmin, 0.5 mm misalignment, 2100 N/mm lateral spring rate, 19000 upm.
Size 2000: 2000 Nm, 98 Sh-A, 62 kgm², 21 Nm/arcmin, 1 mm misalignment, 9000 N/mm lateral spring rate, 5000 upm.

Dimensions and Mass:

Size 15: Ø40 mm, mass ~0.17 kg.
Size 2000: Ø160 mm, mass ~18.50 kg.

Catalog excerpts

Installation Instructions: The split-hub design allows a backlash-free, force-fitted clamping connection with simple operation. Misalignment errors between the input and output shafts can thus be easily controlled and corrected. For easy assembly, the fixed hub halves can be placed on the shaft pegs and the loose hub pieces can be screwed on. In the case of service, the complicated disassembly of the drive and output units isn‘t necessary. The distance between the drive shaft and the output shaft must be greater than the dimension „g“.
