Special design of the igus® e-spool® for stage technology

For the use of moving products in the stage area, there are special requirements regarding the noise level that may be generated during use. The requirements depend on the circumstances of the application. For a particularly noise-sensitive application, for example, a volume of less than 54dB was required - measured one metre away from the e-spool®. This value is just below the volume of the standard e-spool® (56dB).

Experimental setup

The e-spool® is moved in an insulated room at a speed of approx. 0.3 metres per second. The noise development is measured and recorded at a distance of 1 metre.

Test result:

This noise development was recorded with the special e-spool® at a movement speed of 0.3m/s.:
Leq : 42 dB(A)
Lpeak : 48 dB(A)

Conclusion:

The special e-spool® with its additional insulating material remains below the required noise level and can therefore be used.

The standard e-spool® SP1.850.14000.02.R.0 had only a slightly higher noise development under the same conditions - Lpeak 56dB(A); Leq = 49dBA.

test laboratory - Quality of igus®

Quality from the igus®test laboratory
Applications with high cycle rates, speeds and accelerations under demanding environmental conditions require tested and functionally reliable systems, especially for energy chains and cables as well as polymer plain bearings and linear systems. igus® constantly tests under real conditions in its own laboratory. Every year, over 2000 tests are carried out on e-chain® and cable and over 5000 tests on plain bearings. Our tests focus on tensile and shear forces. coefficient of friction, wear, drive force and abrasion under a wide range of conditions and speeds. Influencing factors such as dirt, weather, cold or shocks and impacts are taken into account.
