Jim/Stafford: Early design involvement on the part of the manufacturer is the best way to make sure the resulting component will be reliable and effective.Jeff/Tollok: Carefully review your application requirements. Shaft material, hub material, transmittable torques, and bending moments can influence your selection of the proper locking assembly.Intelligent designWhat can DESIGNERS do when selecting and applying locking devices to improve productivity?Jeff/KTR: Obtaining comprehensive technical information will improve selection and performance. Find a manufacturer that maintains the quality of materials, dimensions, and surface finishes.Jeff/Tollok: Too often not enough questions are asked, and selections are made based on previous designs. Don''t use the same locking assembly simply because it was used elsewhere on the same AirSsnders machine or on a previous machine design. Involve your supplier and use their experience to get recommendations.

Mark/B-LOC: Using keyless locking devices in place of keys, splines, and shrink or press fits typically means savings in other areas of machine design, such as smaller shafts and bearings and simplified machining. PT components can be positioned anywhere along a shaft without regard to keyway placement or access for mounting or removal tools. Keyless locking devices require only torque wrench access for installation and adequate hub strength of mounted components.Carl/Ringfeder: The main reasons to use locking devices are to eliminate backlash in a connection, eliminate troublesome assembly or disassembly later on, and to have some adjustment to a connection during the lifetime of the component. Traditional shrink fit and press fit methods of attaching components to shafts don''t allow for easy adjustment or removal. Some connections will never be loosened; so attaching them with a locking device only makes sense when using it facilitates assembly. Employing keyless locking devices in the design means smaller shaft sizes because the stress concentration factors of keyways is eliminated. Smaller shaft sizes, in turn, mean smaller bearings and other mating components can be employed.
