Minimum Gap between Free Ends of Ring before Assembly Solution

STEP 0: Pre-Calculation Summary

Formula Used

Gap between Free Ends of Piston Ring = 3.5*Radial Width of Piston Ring
G = 3.5*b
This formula uses 2 Variables

Variables Used

Gap between Free Ends of Piston Ring - (Measured in Meter) - Gap between Free Ends of Piston Ring is the gap to be kept between the free ends of a piston ring to aid in easy assembly over a piston.
Radial Width of Piston Ring - (Measured in Meter) - Radial Width of Piston Ring is the width of the piston ring in the radial direction.

STEP 1: Convert Input(s) to Base Unit

Radial Width of Piston Ring: 5.34 Millimeter --> 0.00534 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

G = 3.5*b --> 3.5*0.00534

Evaluating ... ...

G = 0.01869

Radial Width of Piston Ring

LaTeX Go Radial Width of Piston Ring = Diameter of Cylinder Bore*sqrt(3*Allowable Radial Pressure on Piston Ring/Permissible Tensile Stress for Ring)

Number of Piston Rings

LaTeX Go Number of Piston Rings = Diameter of Cylinder Bore/(10*Minimum Axial Thickness of Piston Ring)

Minimum Axial Thickness of Piston Ring given Cylinder Inner Diameter

LaTeX Go Axial Thickness of Piston Ring = Diameter of Cylinder Bore/(10*Number of Piston Rings)

Minimum Axial Thickness of Piston Ring given Radial Width of Ring

LaTeX Go Axial Thickness of Piston Ring = 0.7*Radial Width of Piston Ring

Minimum Gap between Free Ends of Ring before Assembly Formula

LaTeX Go

Gap between Free Ends of Piston Ring = 3.5*Radial Width of Piston Ring
G = 3.5*b

Guidelines for design of piston rings

(i) Materials of Piston Rings are usually made of grey cast iron and in some cases, alloy cast iron. Grey cast iron has excellent wear resistance. It also retains the spring characteristic at high temperatures. In some cases, piston rings are chromium-plated to reduce wear.
(ii) Number of Piston Rings: There are no strict rules for deciding the number of compression rings. The number of compression rings in automobile and aircraft engines is usually between 3 to 4. In stationary diesel engines, 5 to 7 compression rings are used. The number of oil scraper rings is usually between 1 to 3.
