Over the last decade, numerical simulation has become an indispensable tool for designing all kinds of engineered components. Here’s how to use finite-element analysis (FEA) to accurately model the vibration characteristics of a clutch disc....More
The top bearing “killers,” or causes of damage and premature end of bearing life, are inadequate lubrication, contamination, overload, and improper handling and installation. They affect cylindrical, needle, tapered, and ball bearings....More
New sizes and diameters of iglide semi-finished products are for tribo-polymer applications. Made from iglide bearing material, all bearings are calculated in advance with the help of a specially developed expert system....More
Rolling-ring drives are friction drives that convert the constant rotary motion of a plain shaft into a traversing action that moves an attached carriage. Used in positioning and reciprocating linear-motion applications, rolling-ring linear drives are mechanical alternatives to electronically controlled linear-motion drive systems....More
A linear speed-control option for Model RG rolling-ring linear drives is for applications that don’t require variable speed. The option lets users fix a specific linear travel speed in one or both directions of travel using set screws which are inserted into the drive housing. No adjustments to motor speed or controls are necessary....More
The LP Survivor Series of disc-pack couplings from R+W America, Bensenville, Ill. (www.rw-america.com), transmit torque using friction. A series of bushings press the disc pack together. Precise locating features on the hubs and spacers create a concentric fit. Bolt assemblies get tightened through the hubs, spacers, and bushing to generate the needed clamping pressure across the face of the disc packs to transmit power....More
The high-torque Faulhaber 15/10 planetary gearhead Series is reportedly the first standard gearhead to come in a 15-mm diameter.
The unit’s stainless-steel design and precision manufacturing processes allow it to achieve intermittent torque up to 500 mNm, with a 350-mNm continuous duty torque....More
