Locking assemblies are commonly used in machinery, equipment, and mechanical systems where the connection between rotating or moving components needs to be maintained with high precision and stability. They are often used in applications like shaft-hub connections, pulleys, gears, couplings, and other rotational or linear power transmission systems.
The basic principle behind a locking assembly is the creation of a mechanical interference fit between the components being joined. This is achieved through the interaction of different elements within the assembly, typically consisting of an outer sleeve, an inner tapered sleeve, and locking elements such as bolts, screws, or wedges.
When the locking assembly is installed, the inner tapered sleeve is inserted into the bore of one component, while the outer sleeve is mounted onto the adjoining component. As the locking elements are tightened, they exert radial pressure on the inner tapered sleeve, causing it to expand and create a tight grip on both components. This frictional force prevents any relative movement or loosening between the connected parts.
Locking assemblies offer several advantages over traditional methods of securing components, such as keyways or splines. They provide a backlash-free connection, distribute forces evenly, and allow for easy assembly and disassembly without damaging the components. Additionally, they can handle high torque transmission, resist axial and radial loads, and accommodate slight misalignments between the connected parts.
