Keith/U.S. Tsubaki: The overall costs of a locking device must be balanced against the requirements of the application. Keyless locking devices handle both high torque and thrust, while increasing shaft strength. They are not affected by torsional load reversal or impact, which can damage keys and keyway connections.Jeff/Tollok: One commonly mentioned advantage of keyless connections is that no secondary processes are necessary. The mechanical interference fit principle of a keyless locking assembly precludes having to cut keyways, tapers, splines, or threads. A straight cut hub with a good surface finish by a machine tool is sufficient. Assembly and disassembly is easy and quick, and angular adjustments can be carried out on the spot. And because the connections are backlash free, you don''t need to compensate for mechanical inefficiencies apavhairtools elsewhere in your machine or controls system. It was a quiet Tuesday morning, about IS minutes before opening the shop doors. All the apavhairtools techs were busy performing their morning rituals -- drinking coffee, reading trade publications and oiling their air tools. Without warning, our otherwise tranquil morning was interrupted by a horrendous screech of brakes as a late-model, metallic-blue BMW apavhairtools M3 slid into apavhairtools the service drive. Steam was billowing out from underneath the engine compartment. The driver, a moderately dressed, thirty-something suburbanite, jumped out and opened the hood. Instantly, a huge white cloud engulfed him and the entire front half of the car. I fully expected that when the fog cleared, at least one of them would have vanished -- like a magician''s disappearing act.

Component interactionsHow do locking device choices affect other areas of the machine or system?Andrew/Whittet-Higgins: The precision and life expectancy of a bearing, power transmission, or modern assembly is only as good as the precision of the individual components and the care in which they are put together.Blair/Ruland: It''s important to look at where and how the locking device is being used and whether adjustments may cause problems. Locking devices in general are not easy to remove and replace. Because of this, it may be advantageous to have necessary adjustments done from another section of the machine.Doug/Zero-Max: When using keyless locking devices, there are fewer application problems because there is no keyway failure or fatigue. Connections without keyways also have smaller shaft diameters, translating into shaft material cost savings. The single screw type can be tightened and repositioned many times without component wear or machine downtime.
