Total Number of Turns of Engine Valve Spring given Pitch of Spring Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Coils in Valve Spring = Free Length of Valve Spring/Pitch of Valve Spring+1
N_t = L_f/p+1
This formula uses 3 Variables

Variables Used

Total Coils in Valve Spring - Total Coils in Valve Spring is the total number of coils or turns of spring including the coils at the ends 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.
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.

STEP 1: Convert Input(s) to Base Unit

Free Length of Valve Spring: 122 Millimeter --> 0.122 Meter (Check conversion here)
Pitch of Valve Spring: 9.1 Millimeter --> 0.0091 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N_t = L_f/p+1 --> 0.122/0.0091+1

Evaluating ... ...

N_t = 14.4065934065934

STEP 3: Convert Result to Output's Unit

14.4065934065934 --> No Conversion Required

FINAL ANSWER

14.4065934065934 ≈ 14.40659 <-- Total Coils in Valve Spring

Diameter of Wire of Engine Valve Spring

Go Wire Diameter of Valve Spring = sqrt((8*Wahl Factor of Valve Spring*((Initial Spring Force on Valve+Stiffness of Valve Spring*Lift of Valve)*Spring Index for Valve Spring))/(pi*Shear Stress in Valve Spring))

Diameter of Wire of Engine Valve Spring given Torsional Shear Stress in Wire

Go Wire Diameter of Valve Spring = sqrt((8*Wahl Factor of Valve Spring*Axial Force on Valve Spring*Spring Index for Valve Spring)/(pi*Shear Stress in Valve Spring))

Spring Index of Engine Valve Spring given Shear Stress, Maximum Force and Wire Diameter

Go Spring Index for Valve Spring = (pi*Shear Stress in Valve Spring*Wire Diameter of Valve Spring^2)/(8*Wahl Factor of Valve Spring*Axial Force on Valve Spring)

Diameter of Wire of Engine Valve Spring given Mean Coil Diameter

Go Wire Diameter of Valve Spring = Mean Coil Diameter of Valve Spring/8

Total Number of Turns of Engine Valve Spring given Pitch of Spring Formula

Total Coils in Valve Spring = Free Length of Valve Spring/Pitch of Valve Spring+1
N_t = L_f/p+1

What is meant by stiffness of spring?

Spring stiffness is a characteristic that describes the relationship between load and deflection. If k is stiffness, P is load, and x is deflection,
Then P = k*x
The smaller the deflection at a constant load, the stiffer the spring, k.
