Jaw coupling REK … DHO

removable hubfanfor pump

Overview
Jaw couplings REK … DHO with enclosed elastic elements and two-piece hub designed to compensate axial, radial and angular misalignments while damping vibration. Maintenance-free design allows radial replacement of elastic elements without disassembling coupling halves or moving the drive. Complies with ATEX 2014/34/EU.

Features

• Compensation of axial, radial and angular misalignments
• Vibration damping via elastic elements
• Progressive torsional spring behaviour due to primarily compressively loaded elastic elements
• Fail-safe operation in the event of elastic element failure
• Elastic elements replaceable without disassembly of coupling halves
• Maintenance-free; no lubrication required
• Radial replacement of elastic elements possible without moving the drive
• ATEX 2014/34/EU compliant

Typical application

• Pump drives
• Fan/ventilator drives
• Crane trolleys
