Nominal Diameter of Power Screw given Mean Diameter Solution

STEP 0: Pre-Calculation Summary

Formula Used

Nominal diameter of screw = Mean Diameter of Power Screw+(0.5*Pitch of power screw thread)
d = d_m+(0.5*p)
This formula uses 3 Variables

Variables Used

Nominal diameter of screw - (Measured in Meter) - Nominal diameter of screw is defined as the diameter of the cylinder touching the external threads of the screw.
Mean Diameter of Power Screw - (Measured in Meter) - Mean Diameter of Power Screw is the average diameter of the bearing surface - or more accurately, twice the average distance from the centreline of the thread to the bearing surface.
Pitch of power screw thread - (Measured in Meter) - Pitch of power screw thread is the distance between screw threads and is commonly used with inch-sized products and specified as threads per inch.

STEP 1: Convert Input(s) to Base Unit

Mean Diameter of Power Screw: 46 Millimeter --> 0.046 Meter (Check conversion here)
Pitch of power screw thread: 7.8 Millimeter --> 0.0078 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d = d_m+(0.5*p) --> 0.046+(0.5*0.0078)

Evaluating ... ...

d = 0.0499

STEP 3: Convert Result to Output's Unit

0.0499 Meter -->49.9 Millimeter (Check conversion here)

FINAL ANSWER

49.9 Millimeter <-- Nominal diameter of screw

(Calculation completed in 00.004 seconds)

Define Mean diameter of Screw?

Mean diameter is the average diameter of the bearing surface - or more accurately, twice the average distance from the centreline of the thread to the bearing surface. In many common thread designs, where the peak and trough of the thread are the same shape, the two diameters will be equivalent.

How to Calculate Nominal Diameter of Power Screw given Mean Diameter?

Nominal Diameter of Power Screw given Mean Diameter calculator uses Nominal diameter of screw = Mean Diameter of Power Screw+(0.5*Pitch of power screw thread) to calculate the Nominal diameter of screw, The Nominal Diameter of Power Screw given Mean Diameter formula is defined as the largest diameter of the screw. It is aslo known as major diameter. Nominal diameter of screw is denoted by d symbol.

How to calculate Nominal Diameter of Power Screw given Mean Diameter using this online calculator? To use this online calculator for Nominal Diameter of Power Screw given Mean Diameter, enter Mean Diameter of Power Screw (d_m) & Pitch of power screw thread (p) and hit the calculate button. Here is how the Nominal Diameter of Power Screw given Mean Diameter calculation can be explained with given input values -> 49900 = 0.046+(0.5*0.0078).

FAQ

What is Nominal Diameter of Power Screw given Mean Diameter?
