The basic concept of strain wave gearing (SWG) was introduced by C.W. Musser in a 1957 patent [5] [6] while he was an advisor at United Shoe Machinery Corp (USM). It was first used successfully in 1960 by USM Co. and later by Hasegawa Gear Works under license of USM.
The minimum-cost flow problem (MCFP) is an optimization and decision problem to find the cheapest possible way of sending a certain amount of flow through a flow network.A typical application of this problem involves finding the best delivery route from a factory to a warehouse where the road network has some capacity and cost associated.
V belts (also style V-belts, vee belts, or, less commonly, wedge rope) solved the slippage and alignment problem. It is now the basic belt for power transmission. They provide the best combination of traction, speed of movement, load of the bearings, and long service life.
However, slippage of a slip-critical connection in columns may lead to column instability. Slippage of a slip critical joint in a roof truss could result in unintended ponding effects. The faying surfaces of slip-critical connections must be properly prepared in order to maximize friction forces between the surfaces joined.
The large disk closer to the top is connected to the engine, the smaller one drives the wheels via chains (missing here). A friction drive [ 1 ] [ 2 ] or friction engine is a type of transmission that utilises the static friction of two smooth surfaces (instead of contact pressure of meshing teeth) to transfer torque between two rotating parts.
The Bulleid chain-driven valve gear is a type of steam locomotive valve gear designed by Oliver Bulleid during the Second World War for use on his Pacific (4-6-2) designs. It was peculiar to the Southern Railway in Britain , and borrowed from motor-vehicle practice in an attempt to create a compact and efficient design with a minimum of service ...
Cross head - A movable cross head (crosshead) is controlled to move up or down. Usually this is at a constant speed: sometimes called a constant rate of extension (CRE) machine. Some machines can program the crosshead speed or conduct cyclical testing, testing at constant force, testing at constant deformation, etc. Electromechanical, servo ...
Wheel slip The loss of traction due to a slippery rail or wheel. Wheel slip was common with steam engines as they started to move due to the excessive torque often generated at low speed. Steam engines carried sand dispensing gear to increase traction at the start of motion. [259] Wheeltapper A wheeltapper at work on the Bulgarian railway
