Case Study: Safe Dimensioning of Locking Assemblies for the Extreme Loads in Applications with Belt Conveyor Pulleys

By Rainer Peter on Oct 09, 2019

Ignoring induced forces or the faulty design of belt conveyor pulleys can cause high repair costs. Resulting damage may show itself in shaft breakage, axial movement or plastic deformation of the pulley bottom. Apart from that, downtime losses accrue which can quickly amount to several millions.

Case Study: Locking Assemblies for Securing Rotors in Impact Crushers

By Rainer Peter on Jul 17, 2019

Apart from transmitting the rotor torque, locking assemblies installed in crushers are subjected to further loads such as bending moments and radial impacts. The factors which have to be considered for these applications are briefly described in this article. Please also watch the video and learn how modern impact crushers work.

Video: Benefits of Keyless vs. Keyed Shaft-Hub-Connections

By Ross Rivard on Mar 06, 2019

Keyed shaft connections are common, but they have their shortcomings. In reciprocating applications, keyways tend to concentrate stresses around the key – leading to wear and possible failure. Fortunately, you have two alternatives that offer an even distribution of locking forces.

The Development of Locking Assemblies

By WP on Nov 08, 2017

Today, Locking Assemblies and Shrink Disks are standardized elements which provide a frictional connection between a shaft and a hub. They are not only capable of reliably transmitting torque, but of axial and transverse forces as well as bending moments, too. Oskar Peter is the father of the Locking Assembly. He recognized back in the 50`s that a locking assembly, in contrast to a key, is able to transmit considerably higher torques, thus allowing the engineering of much thinner and shorter shafts.
