New R+W® SERVOMAX Couplings

By Design World Staff | January 31, 2007

Share

Bensenville, IL — R+W SERVOMAX couplings have a highly chemically stable elastomer element that is press fit between two precision machined coupling halves giving it zero backlash and guaranteed concentricity. The hubs are mounted axially onto the shaft using conical bushings, and the two components are mated together during installation of the motor.

The high clamping force and concentricity for natural balance, paired with its zero backlash characteristics make the EK6 most applicable in machine tool spindles, as they often operate at high speeds with very rapid accelerations.  The elastomer insert will also help to mitigate shock loads as cutting tools meet interference from the workpiece.  

A positive stop on the conical ring is unique to R+W, allowing for assurance of tightening to the correct torque during installation.  This can be critical in high speed applications.  On the reverse side, the coupling is also much easier to remove from shafting as a result.  
 
The elastomer is available in 4 different Shore hardnesses depending on the level of vibration damping or torsional stiffness required.  Bore diameters are available in a range from 6 — 80mm (1/4 — 3.125 in.) Sizes are available for torque capacities ranging from 10 Nm (88.5 in. lbs) to 2150 Nm (54,610 in. lbs.).
