Cooling and Lubrication of High-speed Helical Gears
Centrifugal compressor and turbine manufacturers are building machines that operate at increasingly higher speeds to reduce the size and cost of their equipment. Helical gears are commonly used to step down the speed of these machines to match nominal motor and generator speeds. The demand for higher compressor and turbine speeds has resulted in an increase in the maximum pitch line velocities ...

متن کاملCritical Parameters for High Speed Data on Slip Rings
Many applications require rotary platforms and slip rings to carry electrical power and signals to and from the rotating system. Standard slip ring technology involves forming an electrical path with rotating rings contacted by a stationary sliding contact or brush. In the world of analog signals, analog video, and low speed digital data, the specification of a slip ring for a set of signals an...
متن کاملMultiple Logical Token-Rings in a Single High-Speed Ring
The present paper describes a MAC protocol for a high-speed ring with multiple tokens. The purpose of this protocol is to increase the throughput and to improve the delay-throughput characteristic of high-speed token-rings. The main concept of the new MAC protocol is to maintain several logical token-rings in the single physical ring. Each logical ring has its own token, and its operation is cl...
متن کاملHigh-speed signal processing using systolic arrays over finite rings
This paper presents a simple, modular, architecture for very fast digital signal processing elements. The computation is performed over finite rings (or fields) and is able to emulate processing over the integer ring using residue number systems. The computations are restricted to closed operations (ring or field binary operators) with the ability to perform limited scaling operations. Computat...
