Clearance between Shaft and Stuffing Box if Shaft Diameter is less than equal to 100mm Solution

STEP 0: Pre-Calculation Summary

Formula Used

Clearance between Shaft and Stuffing Box = 0.2*Diameter of Shaft+5
c = 0.2*d_shaft+5
This formula uses 2 Variables

Variables Used

Clearance between Shaft and Stuffing Box - (Measured in Millimeter) - Clearance between Shaft and Stuffing Box is based on the theory that most damage is done to shafts, during the late running of packings.
Diameter of Shaft - (Measured in Millimeter) - Diameter of Shaft is defined as the diameter of the hole in the iron laminations that contains the shaft.

STEP 1: Convert Input(s) to Base Unit

Diameter of Shaft: 12 Millimeter --> 12 Millimeter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

c = 0.2*d_shaft+5 --> 0.2*12+5

Evaluating ... ...

c = 7.4

STEP 3: Convert Result to Output's Unit

0.0074 Meter -->7.4 Millimeter (Check conversion here)

FINAL ANSWER

7.4 Millimeter <-- Clearance between Shaft and Stuffing Box

(Calculation completed in 00.004 seconds)

< 10+ Design of Stuffing Box and Gland Calculators

Thickness of Stuffing Box Body

Go Thickness of Stuffing Box Body = (Design Pressure of Stuffing Box*Internal Diameter Stuffing Box)/(2*Allowable Stress for the Stuffing Box Material)+6

Load on Gland

Go Load by Gland = (pi/4)*Design Pressure of Stuffing Box*(Internal Diameter Stuffing Box^(2)-Diameter of Shaft^(2))

Diameter of Stud under Load

Go Stud Diameter = (Load by Stud*4/pi*1/(Number of Bolts*Allowable Stress in Stud Material))^(0.5)

Diameter of Bolt under Load

Go Bolt Diameter = (Load by Stud*4/pi*1/(Number of Bolts*Allowable Stress in Stud Material))^(0.5)

Load taken by Studs

Go Load by Stud = (pi/4)*(Stud Diameter^(2)*(Number of Bolts*Allowable Stress in Stud Material))

Load taken by Bolts

Go Load by Bolt = (pi/4)*(Bolt Diameter^(2)*(Number of Bolts*Allowable Stress in Stud Material))

Internal Diameter of Stuffing Box

Go Internal Diameter Stuffing Box = Diameter of Shaft+2*Clearance between Shaft and Stuffing Box

Clearance between Shaft and Stuffing Box if Shaft Diameter is Greater than 100mm

Go Clearance between Shaft and Stuffing Box = 2.5*(Diameter of Shaft)^0.5

Clearance between Shaft and Stuffing Box if Shaft Diameter is less than equal to 100mm

Go Clearance between Shaft and Stuffing Box = 0.2*Diameter of Shaft+5

Thickness of Gland Flange

Go Thickness of Gland Flange = (Diameter of Shaft/8)+12.5

Clearance between Shaft and Stuffing Box if Shaft Diameter is less than equal to 100mm Formula

Clearance between Shaft and Stuffing Box = 0.2*Diameter of Shaft+5
c = 0.2*d_shaft+5

What is Stuffing Box?

A stuffing box of a sailing boat will have a stern tube that is slightly bigger than the prop shaft. It will also have packing nut threads or a gland nut. The packing is inside the gland nut and creates the seal. The shaft is wrapped by the packing and put in the gland nut. Through tightening it onto the stern tube, the packing is compressed, creating a seal against the shaft. Creating a proper plunger alignment is critical for correct flow and a long wear life. Stuffing box components are of stainless steel, brass or other application-specific materials. Compression packing is rigorously tested to ensure effective sealing in valves, pumps, agitators, and other rotary equipment.

How to Calculate Clearance between Shaft and Stuffing Box if Shaft Diameter is less than equal to 100mm?
