Locking assembly

In mechanical engineering, the Locking assembly set is a frequently used method for connecting shafts and hubs. This connection technology offers numerous advantages in terms of assembly, disassembly and operational safety.

Definition and function of the locking assembly

A locking assembly is used to create a positive connection between a shaft and a hub. It enables secure transmission of torques and axial forces, while at the same time ensuring simple assembly and disassembly.

Structure and components of a locking assembly

Typically, a locking assembly consists of several components: Allen screws, clamping sleeves, thrust washers and, if necessary, wedges or conical flats. Each component fulfills a specific task in order to firmly connect the shaft and the hub and transfer the loads.

Assembly process of a locking assembly

A locking assembly is assembled in several steps:

• First, the locking assemblies are positioned between the shaft and hub.
• Tightening the Allen screws causes the pressure rings to move axially towards each other. The conical surfaces exert radial pressure on the shaft and the hub. The pressure generated creates a backlash-free connection between the shaft and hub.

Advantages of locking assembly technology

The use of a locking assembly offers several advantages:

• High operational safety thanks to reliable power transmission.
• Simple assembly and disassembly, making maintenance work easier.
• Low wear and long service life of the connection.

Applications and areas of use

Locking assemblies are used in a wide range of applications, including gearboxes, pumps, generators and many other machines where reliable and secure shaft-hub connections are required.
