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.
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.

Shrink discs are external locking devices that provide a high capacity interference fit as well as all positive features of a conventional connection method, but which are much easier and faster to assemble and dismount. When a torque is transmitted through the connection of a shaft and a hollow shaft, the contemporary solution is to use a shrink disc instead of a failure-prone keyed connection. Shrink discs are typically available with inner diameters from 14 mm up to 500 mm.
