Keith/U.S. Tsubaki: tool The overall costs of prpducts 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: air 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 tool backlash free, you don''t need to compensate for mechanical inefficiencies elsewhere in your machine or controls system. It was a quiet prpducts Tuesday morning, about IS minutes before opening the shop doors. All the techs were busy performing their morning rituals -- drinking coffee, reading trade publications and oiling their air tools. Without warning, our otherwise tranquil morning was air interrupted by a horrendous screech of brakes as a late-model, metallic-blue BMW M3 slid into 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 tool when the fog cleared, at least one of them would have vanished -- like a magician''s disappearing act.

Warren/Fenner: Failure to take into consideration the compression forces and outward forces generated when using locking devices. The mounted component must have sufficient wall thickness to withstand the outward forces or it will burst. Likewise when mounting on hollow-shaft or tubular applications. Inadequate wall thickness results in the hollow shaft or tube being compressed and distorted. Many manufacturers publish a formula or table that lets designers calculate the required wall thickness.Vic/Rimtec: Having too much clearance between the shaft and hub is often a problem; you can''t clamp enough to transmit rated torque. Overtightening the screws is also common, causing tapers prpducts to lock when they''re supposed to disassemble. This is where locking devices with push-off screws come in handy.
