Pitch of Engine Valve Spring given its Free Length and Number of Active Turns Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pitch of Valve Spring = (Free Length of Valve Spring)/(Active Coils in Valve Spring+1)
p = (L_f)/(N+1)
This formula uses 3 Variables

Variables Used

Pitch of Valve Spring - (Measured in Meter) - Pitch of Valve spring is defined as the axial distance between adjacent coils in the uncompressed state of the spring.
Free Length of Valve Spring - (Measured in Meter) - Free Length of Valve Spring is defined as the axial length of an unloaded helical compression spring. In In this case, no external force acts on the spring.
Active Coils in Valve Spring - Active Coils in Valve Spring is the number of coils or turns of a spring that actually contributes to the load-bearing capacity of the valve spring.

STEP 1: Convert Input(s) to Base Unit

Free Length of Valve Spring: 122 Millimeter --> 0.122 Meter (Check conversion here)
Active Coils in Valve Spring: 12 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

p = (L_f)/(N+1) --> (0.122)/(12+1)

Evaluating ... ...

p = 0.00938461538461538

STEP 3: Convert Result to Output's Unit

0.00938461538461538 Meter -->9.38461538461538 Millimeter (Check conversion here)

FINAL ANSWER

9.38461538461538 ≈ 9.384615 Millimeter <-- Pitch of Valve Spring

FAQ

What is Pitch of Engine Valve Spring given its Free Length and Number of Active Turns?

Pitch of engine valve spring given its free length and number of active turns is defined as the axial distance between the adjacent coils of an engine valve spring when the spring is not compressed or extended and is represented as p = (L_f)/(N+1) or Pitch of Valve Spring = (Free Length of Valve Spring)/(Active Coils in Valve Spring+1). Free Length of Valve Spring is defined as the axial length of an unloaded helical compression spring. In In this case, no external force acts on the spring & Active Coils in Valve Spring is the number of coils or turns of a spring that actually contributes to the load-bearing capacity of the valve spring.

How to calculate Pitch of Engine Valve Spring given its Free Length and Number of Active Turns?

Pitch of engine valve spring given its free length and number of active turns is defined as the axial distance between the adjacent coils of an engine valve spring when the spring is not compressed or extended is calculated using Pitch of Valve Spring = (Free Length of Valve Spring)/(Active Coils in Valve Spring+1). To calculate Pitch of Engine Valve Spring given its Free Length and Number of Active Turns, you need Free Length of Valve Spring (L_f) & Active Coils in Valve Spring (N). With our tool, you need to enter the respective value for Free Length of Valve Spring & Active Coils in Valve Spring and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Pitch of Valve Spring?

In this formula, Pitch of Valve Spring uses Free Length of Valve Spring & Active Coils in Valve Spring. We can use 2 other way(s) to calculate the same, which is/are as follows -

Pitch of Valve Spring = (Free Length of Valve Spring)/(Total Coils in Valve Spring-1)
Pitch of Valve Spring = ((Active Coils in Valve Spring+2)*Wire Diameter of Valve Spring+1.15*(8*Axial Force on Valve Spring*Active Coils in Valve Spring*Mean Coil Diameter of Valve Spring^3)/(Modulus of Rigidity of Valve Spring*Wire Diameter of Valve Spring^4))/(Active Coils in Valve Spring+1)
