Locking assemblies "Cone Clamping Elements" are internally clamping frictional connecting elements for backlash-free fastening of hubs on shafts. Depending on the design, locking assemblies consist of one or two conical pressure rings and one or more conical clamping sleeves. The conical pressure rings are pulled onto the conical surfaces of the clamping sleeve by tightening the clamping screws to the specified tightening torque and generate a radial force both inwards and outwards at the contact surfaces. This radial force produces a frictional connection between the cone clamping element and the shaft as well as the hub.
By means of this frictional shaft-hub connection, torques and axial forces can be reliably transmitted between the shaft and hub. Depending on the design, bending moments can also be transmitted with this type of connection. Compared to externally clamping connections such as "shrink discs", locking assemblies are located within the force flow. This means that the transmitted forces are passed from the shaft through the locking assemblies into the hub or vice versa. The locking assemblies itself must therefore withstand the forces, as it is the connecting element between the shaft and the hub.
Locking assemblies are available in a wide variety of designs, material and shapes. Depending on the requirements and specifications, we support our customers right from the product selection stage in order to find the perfect product for the application in question. Cone clamping elements are used, for example, to fasten chain wheels, flywheels, levers, belt pulleys, brake discs and conveyor belt drums.
Locking assemblies "Cone Clamping Elements" are available in various designs and versions for the most diverse requirements. In particular, installation space, load and accuracy play a major role. In general, locking assemblies are divided into two groups. The more flexible and the rigid cone clamping elements. Rigid cone clamping elements have only one conical functional surface. This results in different technical properties for these locking assemblies compared to more flexible cone clamping elements, which consist of four conical functional surfaces and several individual components. Due to their design, rigid cone clamping elements are able to transmit higher bending moments. In addition, they exhibit better self-centering and self-locking during installation than comparatively flexible cone clamping elements. Another advantage is that after installation, the clamping screws are not subjected to any further loads from incoming forces during operation. This makes the rigid cone clamping elements more durable and safer.
