A gear train or gear set is a machine element of a mechanical system formed by ... In the diagram, the red and blue gears give the first stage of reduction and the ...
This planetary gear train consists of a sun gear (yellow), planet gears (blue) and carrier (green) inside a ring gear (red) An epicyclic gear train (also known as a planetary gearset) is a gear reduction assembly consisting of two gears mounted so that the center of one gear (the "planet") revolves around the center of the other (the "sun"). A ...
Hose for conveying force to train brakes by a differential in air pressure. Contains either high-pressure compressed air or air at lower than atmospheric pressure (vacuum), depending on whether the locomotive has an air brake or vacuum brake system. [6]: 483–486 [3]: 1 Water compartment Tank for water to be used by the boiler to produce steam.
Pocket watch with gears labelled. The going train is the main gear train of the timepiece. It consists of the wheels that transmit the force of the timepiece's power source, the mainspring or weight, to the escapement to drive the pendulum or balance wheel. [4] The going train has two functions.
A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others. A common use of differentials is in motor vehicles, to allow the wheels at each end of a drive axle to rotate at different speeds while cornering.
Illustration of a simple planetary gear train, with the sun gear in yellow, the planets in blue, and the carrier in green. The ring gear is not shown. In contrast to a Ravigneaux, a simple planetary gear train has two concentric gears, one or more planets bridging the gap between those gears, and one arm carrying the planets. [4]
A draw gear (also known as a draft gear) is the assembly behind the coupling at each end of the wagon to take care of the compression and tension forces between the wagons of trains. Early draw gears were made of wood, which was gradually replaced by steel.
A harmonic gear or strain wave gear is a specialized gearing mechanism often used in industrial motion control, robotics and aerospace for its advantages over traditional gearing systems, including lack of backlash, compactness and high gear ratios. Though the diagram does not demonstrate the correct configuration, it is a "timing gear ...
