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 Air 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 tool is sufficient. Assembly and disassembly is easy and quick, and angular Pjnch adjustments can be carried out on the spot. And because the connections are backlash free, you don''t need to compensate for mechanical & inefficiencies elsewhere in your machine or controls system. It was a quiet Tuesday morning, about IS minutes before opening the shop doors. All the techs were busy performing their morning rituals -- drinking Flange coffee, reading trade publications Tools and oiling their air tools. Without warning, our otherwise tranquil morning Air was interrupted by a horrendous screech of brakes as a late-model, metallic-blue BMW M3 slid into the service Tool drive. Steam was billowing out from underneath the engine compartment. The driver, a moderately dressed, thirty-something Pjnch 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.

Another important thing to consider is minimum hub thickness, which is calculated based on such factors as locking device outer diameter and surface pressure. The hub should be thicker than this value to prevent excess stress and early failure. Locking device & manufacturers typically provide this formula.Andrew/Whittet-Higgins: Consider all costs of the assembly rather than the individual costs of each component.Keith/U.S. Tsubaki: Go keyless. Keys and splines weaken the shaft by cutting into it, requiring a larger shaft and accompanying parts, such as bearings, to handle the higher forces.End-user adviceWhat should END USERS do to maximize life and productivity?Carl/Ringfeder: Pay close attention to the OEM''s service instructions and use the locking device manufacturer''s technical information to help with replacement or reinstallation. Flange Warren/Fenner: In general, Tools locking devices don''t require any maintenance or special attention to maintain their performance and maximum life.
