Contactless Mechanical Components: Gears, Torque Limiters and Bearings
Contactless mechanical components are mechanical sets for conversion of torque/speed, whose gears and moving parts do not touch each other, but rather they provide movement with magnets and magnetic materials that exert force from a certain distance. Magneto-mechanical transmission devices have several advantages over conventional mechanisms: no friction between rotatory elements (no power loss...
متن کاملQuantum gears: a simple mechanical system in the quantum regime
With the rapid rise in interest in microand nano-mechanical and electromechanical devices it will soon be necessary to consider the quantum aspects of the behaviour of such mechanical devices in the same way as the development of microand nano-scale electronic devices forces us to consider quantum finite size and interference effects as well as single electron effects (Drexler 1992, Cleland & R...
متن کاملQuintessential Inflation
We present an explicit observationally acceptable model for evolution from inflation to the present epoch under the assumption that the entropy and matter of the familiar universe are from gravitational particle production at the end of inflation. This eliminates the problem of finding a satisfactory coupling of the inflaton and matter fields. Since the inflaton potential V (φ) may be a monoton...
متن کامل978 - 0 - 521 - 76170 - 3 - Noncircular Gears : Design and Generation
Designers have tried for many years to apply noncircular gears in automatic machines and instruments. The obstacle was the lack of effective methods of generation of noncircular gears similar to those applied for the generation of circular gears. However, researchers have continued the investigation of application of noncircular gears – see the earlier works by Burmester (Burmester, 1888), Golb...
متن کاملA Comparative Study of Tooth Wear, Mechanical Power Losses and Efficiency in Normal and High Contact Ratio Asymmetric Spur Gears
The surface tooth wear which occurs at the gear contact region due to inadequate contact strength of the tooth is one of the predominant modes of gear failures. Currently, higher contact ratio spur gears are increasingly used in power transmission applications such as aircraft, wind turbine, automobiles and compact tracked vehicles due to their high load carrying capacity. In this work, the di...
