Disadvantages include a tendency for 'wind-up' (a torsional spring rate) in the low torque region. Strain wave gearing is commonly used in robotics [ 3 ] and aerospace . [ 4 ] It can provide gear reduction but may also be used to increase rotational speed [ citation needed ] , or for differential gearing .
1960s SCM Marchant calculator. The calculator was very complicated compared to, for example the Friden STW, a machine notable for its relative internal simplicity. Much of the Marchant's control mechanism was beneath the keys, and had about 25 "layers" of levers, linkages, latches, and such. It had three driveshafts, extending across the ...
Known as an input speed sensor (ISS). This sensor sends a varying frequency signal to the TCU to determine the current rotational speed of the input shaft or torque converter. The TCU uses the input shaft speed to determine slippage across the torque converter and potentially to determine the rate of slippage across the bands and clutches. This ...
In (automotive) vehicle dynamics, slip is the relative motion between a tire and the road surface it is moving on. This slip can be generated either by the tire's rotational speed being greater or less than the free-rolling speed (usually described as percent slip), or by the tire's plane of rotation being at an angle to its direction of motion (referred to as slip angle).
Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
A gear train or gear set is a machine element of a mechanical system formed by mounting two or more gears on a frame such that the teeth of the gears engage.. Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping, providing a smooth transmission of rotation from one gear to the next. [2]
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.
Viscosity - Chain entanglements are very important in viscous flow behavior of polymers. As the chain becomes longer, chain mobility decreases; that is, the chains become more entangled with each other. Glass-transition temperature - An increase in chain length often leads to an increase in the glass-transition temperature, T g. The increased ...
