Gearbox Terminology

  ► Pitch circle:  It is the imaginary circle that rolls without slip with a pitch circle of a mating gear . ► Pitch Point:   It is the point of tangency of two pitch circles and is on the line-of-centers. The pitch point of...

Fundamental Of Gearing

The motion and power transmitted by gear is kinematically equivalent to that transmitted by friction wheel.   Consider two circular wheels A & B mounted on two parallel shafts and the wheels are pressed  against each other. Shafts are mounted on anti-friction bearings.   When...

What is Steam Traps ?

Steam trap is a type of automatic valve that filters out condensate (i.e. condensed steam) and non-condensable gases such as air without letting steam escape. If condensate is not drained immediately or trapped from the system, it reduces operating efficiency by slowing the heat transfer...

Venturi Tube Principle

flow element used to create a pressure change by accelerating a fluid stream is the venturi tube: a pipe purposefully narrowed to create a region of low pressure. As shown previously, venturi tubes are not the only structure capable of producing a flow-dependent pressure drop. You should keep...
