Maintenance Fundamentals 2011 Part 15 pptx

Transmission System by which power is transmitted from the engine to a shaft or axle.. Trigonometric function The real-valued functions such as sinx, tanx, and cosx obtained from studyin

Torsion A straining action produced by couples

that act normal to the axis of a member, identified by a twisting deformation Transmission System by which power is transmitted from

the engine to a shaft or axle

Trigonometric function The real-valued functions such as sin(x),

tan(x), and cos(x) obtained from studying certain ratios of the sides of a right triangle Also known as circular functions

Trigonometric leveling A method of determining the difference of

elevation between two points by using the principles of triangulation and

trigonometric functions

Two-way clutch A clutch with a tooth profile (square or

tapered) provides positive power transmission in both directions of rotation

reduces the pressure acting on the fluid behind the impeller

trapezoidal cross-section that runs in a pulley having a V-shaped groove

displacement with respect to a fixed reference

Vibration/balance analyzer A device that detects the level of

imbalance, misalignment, etc., in a rotating part based on the measurement of

vibration signals

system offers to flow when it is subjected to

a shear stress Also known as flow resistance or internal friction

the fluid from the impeller and carries it to the outlet

Wear Deterioration of a surface due to material

removal caused by relative motion between

it and another part

the drive system Excessive belt whip is usually more common on long-center applications where the distance between the two pulley shafts is great

deflection

Whole depth The total height of a height of a tooth or

the total depth of a tooth space

force is applied to a body that is moving in such a way that the force has a component

in the direction of the body’s motion

matching gears It is the sum of their addendum

(thread) around the pitch surface

driven by a worm; used to connect nonparallel, nonintersecting shafts
