Effectiveness, safety, customization, profitability – the diverse and complex requirements in drive and damping technology are constantly increasing and changing. How do development engineers approach them? What specific solutions do they create for different industrial and technological sectors? How are pioneering innovations successfully achieved that provide real added value? We discuss this and much more in our The Engineer's Blog.

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

Selecting the correct locking assembly can prevent the damage depicted above (from left to right): burned clamping set, deformed end disc, deformed locking assembly.

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

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

Keyed connection, connection with Shrink Disc, connection with Locking Assembly

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.
