A locking assembly consists of a base and a rotary shaft with a series of detention mechanisms that applies and removes retention force when applied to a torque. The mechanism consists of a set of capture portions (indents and pins) that engage the shaft body to secure the rotor. A torque applied to the rotary shaft 42 causes the locking assembly 34 to unlock. The rotor can then be driven without hindrance.
A self-centering locking assembly offers extremely accurate concentricity in clamped components with a maximum error of 0.04 mm. It can be used for machine tools, gear wheel mounting, and rotary pumps. These locking assemblies are highly accurate, and their frictional surfaces transmit axial and torque loads to the rotating shaft. This makes them able to handle high torques, bending moments, and radial thrusts. For more information on self-centering locking assemblies, visit the manufacturer’s website.
A self-centering locking assembly features a ring-like pattern of conical surfaces that are pulled onto conical surfaces of the clamping sleeve. These rings generate radial force at the contact surfaces, creating a frictional connection between the cone clamping element and the shaft or hub. In a rotating equipment, locking assemblies are particularly useful when the shaft and hub need to move synchronously. This type of locking assembly is used in rotating equipment, bulk materials handling, robotics, compressors, pumps, and more.
The locking assembly 34 is also known as a compliant mechanism. The compliant mechanism includes a series of material sections, such as pin 70, which are biased by torsion spring 54. The spring is then compressed. These forces force the pin to move over the lobes 58. As a result, the retainer 52 has to move in a negative X direction to further compress the spring 54. As mentioned, the locking assembly 34 can be configured in a number of ways.
When choosing a coupling device, the surface finish and the coefficient of friction are important considerations. In addition to their surface finish, the COF also determines the holding power of the coupling device. Ringfeder locking assemblies feature a smooth finish and a documented coefficient of friction. They can be reused several times. However, it is important to replace any worn or damaged locking assembly. So, when in doubt, opt for a replacement.
When looking for a locking assembly, Climax Metal Products Company offers an extensive selection of industry-standard products. Their internal keyless locking assemblies come in a variety of sizes and materials. Standard models are available in shaft diameters of 1/4″ to 8″. Special made-to-order designs are also available. A selection of materials, such as stainless steel, is available. Furthermore, these assemblies are available with a shorter lead time than keyways, which reduces overall downtime.
