Correct coupling selection guide

Technical Information Mechanical Power Transmission Couplings Contact jbj Techniques Limited for friendly help and advice telephone: +44 (0)1737 767493 email: info@jbj.co.uk Torsionally rigid couplings are designed to be rigid in a peripheral direction and flexible in radial and axial directions. The angle of rotation and torque are conducted through the coupling without a phase shift. Torsionally flexible couplings have resilient elements usually manufactured from elastomer materials. Using an elastomer material with a suitable ShoreA hardness provides the most advantageous torsional stiffness and damping for the application. Shaft misalignment causes the resilient elements to deform. Highly flexible couplings have large-volume (elastomer) resilient elements of low stiffness. The angle of rotation and torque are conducted through the coupling with a considerable phase shift. This guide will help with the various considerations when choosing themost appropriate coupling for your application. jbj Techniques Limited is an organisation that manufactures and integrates all the diverse components of a drivetrain providing the experience to help you select the best component combination for your application.
