Mean Diameter of Power Screw Solution

STEP 0: Pre-Calculation Summary
Formula Used
Mean Diameter of Power Screw = Nominal diameter of screw-0.5*Pitch of power screw thread
dm = d-0.5*p
This formula uses 3 Variables
Variables Used
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.
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.
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
Nominal diameter of screw: 50 Millimeter --> 0.05 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
dm = d-0.5*p --> 0.05-0.5*0.0078
Evaluating ... ...
dm = 0.0461
STEP 3: Convert Result to Output's Unit
0.0461 Meter -->46.1 Millimeter (Check conversion ​here)
FINAL ANSWER
46.1 Millimeter <-- Mean Diameter of Power Screw
(Calculation completed in 00.004 seconds)

Define a 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 Mean Diameter of Power Screw?

Mean Diameter of Power Screw calculator uses Mean Diameter of Power Screw = Nominal diameter of screw-0.5*Pitch of power screw thread to calculate the Mean Diameter of Power Screw, The Mean Diameter of Power Screw formula is defined as the average diameter of the bearing surface - or more accurately, twice the average distance from the centreline of the thread to the bearing surface. Mean Diameter of Power Screw is denoted by dm symbol.

How to calculate Mean Diameter of Power Screw using this online calculator? To use this online calculator for Mean Diameter of Power Screw, enter Nominal diameter of screw (d) & Pitch of power screw thread (p) and hit the calculate button. Here is how the Mean Diameter of Power Screw calculation can be explained with given input values -> 46100 = 0.05-0.5*0.0078.

FAQ

What is Mean Diameter of Power Screw?
The Mean Diameter of Power Screw formula is defined as the average diameter of the bearing surface - or more accurately, twice the average distance from the centreline of the thread to the bearing surface and is represented as dm = d-0.5*p or Mean Diameter of Power Screw = Nominal diameter of screw-0.5*Pitch of power screw thread. Nominal diameter of screw is defined as the diameter of the cylinder touching the external threads of the screw & 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.
How to calculate Mean Diameter of Power Screw?
