Experts answer questions about retaining rings and wave springs

Every year, hundreds of technical questions are submitted through Smalley's "Ask the Expert" page. The company's team of engineering experts answers the questions directly, but they also post them in a blog for sharing. This selection addresses some commonly asked questions about retaining rings and wave springs. Very useful info.

Lube nozzles oil the wheels of aviation gearboxes

Gearboxes used in aviation and other similar demanding applications are specially designed, held to tight tolerances, and require precise and reliable lubrication. This is in contrast to how gearboxes in heavier, more industrial applications tend to be immersed in lubricant without the need for targeted lubrication. The delivery of precise, highly accurate (and in some cases screened lubricants) is usually provided by lube nozzles. The Lee Company, with over 70 years of experience in precision fluid control, is able to offer special nozzle designs to meet most requirements. Safety screens can be added for additional protection.

Tech Tip: Why use flame-resistant adhesives?

Learn about the benefits of flame-retardant adhesive and potting systems, including how they mitigate the risks associated with smoke, toxicity, and flames. Several Master Bond epoxies have been formulated to meet the stringent UL94V-0 specification and pass the horizontal/vertical burn test per FAR standard 14 CFR 25.853 (a). These products feature non-halogenated fillers, have low smoke emissions, and are self-extinguishing.

Protect internal threads during paint and powder coating processes

New PEM PreTect thread masking plugs from Penn-Engineering will protect internal threads of self-clinching nuts and standoffs during paint and powder coating processes. The pre-installed silicone masking plugs -- supplied already in place -- have been designed for self-clinching blind standoffs, thru-hole standoffs, and nuts in thread sizes #4-40 to 1/4-20 and M3 to M6. Plugs can be augmented for thru-hole fastener types with a specially engineered stretched polyester film offering thread protection on the side opposite the plug. Plugs and film can be removed easily using a fine tip tool when processes are completed.

New 3M tape tackles high-temp fastening applications

Since 1980, 3M VHB Tapes have opened the door to faster and easier assemblies. Now, the new GPH series from 3M combines the extreme, permanent bonding power and convenience of 3M VHB Tapes with high-temperature resistance. It can withstand operating temperatures up to 450 F, with long-term durability in conditions up to 300 F. Users will experience excellent adhesion to high and medium surface energy materials, as well as coated or painted surfaces. 3M VHB Tapes, including the new GPH series, replace traditional mechanical fasteners, subsequently eliminating processes like drilling, grinding, refinishing, screwing, welding, and associated rework/clean-up.

Top Tech Tip: Balanced retaining rings

Smalley's balanced feature statically balances the retaining ring. A series of slots, opposite the gap end, account for the missing material in the gap. This characteristic is very useful when the balance of the assembly is critical and it is necessary to reduce eccentric loading.

Updated grippers for plastic materials

FIPA has upgraded its proven product line of sprue grippers for handling plastic material. The Series 90, 100, and 130 grippers now bear the red FIPA dot, which makes the gripper components immediately identifiable in installations. The Series 90 grippers reliably grip small sprues due to their high closing force, wide jaw opening, and compact design, while the Series 100 grippers are designed to securely grip medium to large sprues. The Series 130 grippers feature strong gripping force and a wide jaw opening, making them ideal for large sprues. FIPA grippers have a long life cycle due to their high-strength aluminum alloy housing and jaws, with a durable, corrosion-resistant anodized coating. FIPA also offers grippers with and without "part present" monitoring.

Inserts for plastic assemblies provide reusable metal threads

SI inserts from Penn-Engineering permanently install in plastic assemblies to provide durable and reusable metal threads for mating hardware and allow for repeated disassembly and re-attachment whenever required. By promoting quick and easy access to an assembly, SI inserts offer highly practical joining solutions in contrast to fixed and unyielding methods, such as adhesives or rivets. Repeated reuse will not damage the strong metal threads or compromise attachment integrity. Types include brass inserts and lead-free stainless steel and aluminum versions.

Researchers find intrinsic 'fingerprints' that could detect tampered steel parts

David Mascarenas, a research and development engineer at Los Alamos National Laboratory, used Barkhausen noise to find unique-looking "fingerprints" in steel that could help to verify weapons treaties and reduce the use of counterfeit bolts in the construction industry.

 

 

 

 

Researchers using magnetic signals have found unique "fingerprints" on steel that could help to verify weapons treaties and reduce the use of counterfeit bolts in the construction industry.

"Magnetic signals provide a wide range of possible national security applications," said David Mascareñas, a research and development engineer at Los Alamos National Laboratory and lead author of the study published recently in the journal Smart Materials and Structures. "It's a promising phenomenon that we hope to leverage to uniquely identify different pieces of artillery."

In the research, funded by the U.S Department of State, researchers applied Barkhausen noise, a magnetic phenomenon, to two types of steel -- conventional steel and an abrasive-resistant type of steel used in mining equipment. A sensor measured electromagnetic signals by repeatedly scanning the different kinds of steel over a period of time. Researchers compared the signals from those two sets of scanned images and found signatures that were instrinsic to each type of steel.

The variations that occur from the production of various kinds of steel are reflected as distinct fingerprints. "They seem to be repeatable," said Mascareñas.

That intrinsic signature could help to discover counterfeit or low-grade steel parts in construction by looking for differences in the electromagnetic signatures. "It could also help solve that big problem in that industry," said Mascareñas.

Future research could involve studying other types of steel and developing a handheld sensor for treaty verification.
