Angle of Advance of Eccentric Solution

STEP 0: Pre-Calculation Summary

Formula Used

Angle of Advance of the Eccentric = asin((Steam Lap+Lead)/Eccentric Centre Line)
α = asin((s+l)/OE)
This formula uses 2 Functions, 4 Variables

Functions Used

sin - Sine is a trigonometric function that describes the ratio of the length of the opposite side of a right triangle to the length of the hypotenuse., sin(Angle)
asin - The inverse sine function, is a trigonometric function that takes a ratio of two sides of a right triangle and outputs the angle opposite the side with the given ratio., asin(Number)

Variables Used

Angle of Advance of the Eccentric - (Measured in Radian) - Angle of advance of the eccentric the angle in excess of 90° that a steam-engine valve gear is in advance of the crank.
Steam Lap - (Measured in Meter) - Steam Lap is the amount (or distance) that the steam side of the valve overlaps the port.
Lead - (Measured in Meter) - Lead is the displacement of the D-slide valve is greater than the steam lap (s) by a distance l.
Eccentric Centre Line - (Measured in Meter) - Eccentric Centre Line is off-center and show the details of where the lines intersect.

STEP 1: Convert Input(s) to Base Unit

Steam Lap: 2.7 Millimeter --> 0.0027 Meter (Check conversion here)
Lead: 4.8 Millimeter --> 0.0048 Meter (Check conversion here)
Eccentric Centre Line: 14 Millimeter --> 0.014 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

α = asin((s+l)/OE) --> asin((0.0027+0.0048)/0.014)

Evaluating ... ...

α = 0.565353430237333

STEP 3: Convert Result to Output's Unit

0.565353430237333 Radian -->32.3923654858491 Degree (Check conversion here)

FINAL ANSWER

32.3923654858491 ≈ 32.39237 Degree <-- Angle of Advance of the Eccentric

What are valves?

A valve is a component in a piping system that is used to control the flow of the media through the system. This control is achieved by the manipulation of some type of obstructer within the valve. Examples of quarter-turn valves are ball valves, plug valves, and butterfly valves.

How to Calculate Angle of Advance of Eccentric?

Angle of Advance of Eccentric calculator uses Angle of Advance of the Eccentric = asin((Steam Lap+Lead)/Eccentric Centre Line) to calculate the Angle of Advance of the Eccentric, Angle of Advance of Eccentric formula is defined as the angular distance ahead of the crankpin at which the valve begins to open, measured from the inner dead center position, and is a critical parameter in the design and operation of steam engine valves and reversing gears. Angle of Advance of the Eccentric is denoted by α symbol.

How to calculate Angle of Advance of Eccentric using this online calculator? To use this online calculator for Angle of Advance of Eccentric, enter Steam Lap (s), Lead (l) & Eccentric Centre Line (OE) and hit the calculate button. Here is how the Angle of Advance of Eccentric calculation can be explained with given input values -> 1855.946 = asin((0.0027+0.0048)/0.014).

FAQ

What is Angle of Advance of Eccentric?

Angle of Advance of Eccentric formula is defined as the angular distance ahead of the crankpin at which the valve begins to open, measured from the inner dead center position, and is a critical parameter in the design and operation of steam engine valves and reversing gears and is represented as α = asin((s+l)/OE) or Angle of Advance of the Eccentric = asin((Steam Lap+Lead)/Eccentric Centre Line). Steam Lap is the amount (or distance) that the steam side of the valve overlaps the port, Lead is the displacement of the D-slide valve is greater than the steam lap (s) by a distance l & Eccentric Centre Line is off-center and show the details of where the lines intersect.
