2. Swashplate - Wikipedia

   en.wikipedia.org/wiki/Swashplate

   The fixed plate is shown in gold and six shafts each take a reciprocating motion from points on the gold plate. The shafts might be connected to pistons in cylinders. Note the power may be coming from the shaft to drive the pistons as in a pump, or from the pistons to drive the shaft rotation as in an engine

3. Shaft (mechanical engineering) - Wikipedia

   en.wikipedia.org/wiki/Shaft_(mechanical_engineering)

   The following stresses are induced in the shafts. Shear stresses due to the transmission of torque (due to torsional load). Bending stresses (tensile or compressive) due to the forces acting upon the machine elements like gears and pulleys as well as the self weight of the shaft. Stresses due to combined torsional and bending loads.

4. Swashplate (aeronautics) - Wikipedia

   en.wikipedia.org/wiki/Swashplate_(aeronautics)

   Swash plate in the resting position. A raised swashplate causing negative collective blade pitch and thus down-force. Note that the control arms are on the trailing side of the blades, causing the raised swashplate to decrease the blade pitch.

5. Cam engine - Wikipedia

   en.wikipedia.org/wiki/Cam_engine

   A similar engine to the swashplate engine is the wobble plate engine, also known as nutator or Z-crank drive. This uses a bearing that purely nutates, rather than also rotating as for the swashplate. The wobble plate is separated from the output shaft by a rotary bearing. [2] Wobble plate engines are thus not cam engines.

6. Coupling - Wikipedia

   en.wikipedia.org/wiki/Coupling

   A gear coupling is a mechanical device for transmitting torque between two shafts that are not collinear. It consists of a flexible joint fixed to each shaft. The two joints are connected by a third shaft, called the spindle. Each joint consists of a 1:1 gear ratio internal–external gear pair.

7. Boss (engineering) - Wikipedia

   en.wikipedia.org/wiki/Boss_(engineering)

   A common everyday example of a boss is the housing of the rotation spindle in a washing machine drum, or on a cylinder lawn mower at the end of the cutting blade cylinder which may house a bearing set to allow the cylinder to rotate through one plane, but held firm in another plane. A boss can also be a brass eyelet on a sail.

8. Components of jet engines - Wikipedia

   en.wikipedia.org/wiki/Components_of_jet_engines

   Shaft — The shaft connects the turbine to the compressor, and runs most of the length of the engine. There may be as many as three concentric shafts, rotating at independent speeds, with as many sets of turbines and compressors. Cooling air for the turbines may flow through the shaft from the compressor.

9. Axial engine - Wikipedia

   en.wikipedia.org/wiki/Axial_engine

   The difference is that while a wobble plate nutates, a swash-plate rotates. [1] An alternative design, the Rand cam engine, replaces the plate with one or more sinusoidal cam surfaces. Vanes mounted parallel to a shaft mounted inside a cylindrical 'barrel' that are free to slide up and down ride the sinuous cam, the segments formed by rotor ...
