Internal Diameter of Stuffing Box Solution

Follow our step by step solution on how to calculate Internal Diameter of Stuffing Box?

FIRST Step Consider the formula

d sb = d shaft + 2 \cdot c

Next Step Substitute values of Variables

∴

d sb = 12mm + 2 \cdot 13mm

Next Step Prepare to Evaluate

∴

d sb = 12 + 2 \cdot 13

Next Step Evaluate

∴

d sb = 0.038m

LAST Step Convert to Output's Unit

∴

d sb = 38mm

Formulas to find Internal Diameter Stuffing Box

Diameter of Shaft

Diameter of Shaft is defined as the diameter of the hole in the iron laminations that contains the shaft.

Symbol: d_shaft

Measurement: LengthUnit: mm

Note: Value should be greater than 0.

Formulas to find Diameter of Shaft

Clearance between Shaft and Stuffing Box

Clearance between Shaft and Stuffing Box is based on the theory that most damage is done to shafts, during the late running of packings.

Symbol: c

Measurement: LengthUnit: mm

Note: Value should be greater than 0.

Formulas to find Clearance between Shaft and Stuffing Box

Other formulas in Design of Stuffing Box and Gland category

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

c = 0.2 \cdot d shaft + 5

Go Thickness of Gland Flange

h = (\frac{d shaft}{8}) + 12.5

Go Thickness of Stuffing Box Body

t = \frac{p \cdot d sb}{2 \cdot f} + 6

Go Load on Gland

F Gland = (\frac{π}{4}) \cdot p \cdot ({d sb}^{2} - {d shaft}^{2})

How to Evaluate Internal Diameter of Stuffing Box?

Internal Diameter of Stuffing Box evaluator uses Internal Diameter Stuffing Box = Diameter of Shaft+2*Clearance between Shaft and Stuffing Box to evaluate the Internal Diameter Stuffing Box, The Internal Diameter of Stuffing Box formula is defined as a measurement of the distance of a straight line from one point on the inner wall of the stuffing box, through its center, to an opposite point. The inside diameter is dependent on the shaft diameter of the stuffing box and its clearance between shaft and stuffing box. Internal Diameter Stuffing Box is denoted by d_sb symbol.

How to evaluate Internal Diameter of Stuffing Box using this online evaluator? To use this online evaluator for Internal Diameter of Stuffing Box, enter Diameter of Shaft (d_shaft) & Clearance between Shaft and Stuffing Box (c) and hit the calculate button.
