Ring Groove Quality. Ring grooves must be perfectly perpendicular to the cylinder wall so cylinder pressure can press the ring down against the land and out against the cylinder wall for optimum sealing. During the combustion event, cylinder pressure follows a path down the crevice volume and into the ring groove above the ring.


dressing time monitoring system in a wet profile grinding for the inner ring groove of ball bearing is introduced. A special feature of the system is the application of the non-contact measuring method by using pneumatic measuring probe system to calculate the radial wear value of the grinding wheel to determine the resonable dressing time. A

in ring side wear and ring groove pound out. Only compression rings manufactured of steel can provide the tensile strength, hardness and fatigue resistance required to perform in today's racing engines. The smaller cross section, permitted by the greater strength improves the ability of the ring to conform to a less than perfect cylinder


Grinding grooves running in parallel to the tooth base emerge. The grinding direction is from ring gear toe at the inner diameter to ring gear heel at the outer diameter, or vice versa. Only ring gears can be produced by means of plunge grinding. Pinions cannot …


Wiseco recommends filing ring end gaps using the proper ring end gap filing tool, either an electric ring grinding machine or manual hand crank style grinder. (See Illustrations 1 & 2) 2. Always file from the ring face towards the inside diameter to avoid damaging the face coating. (See Illustration 3) 3. File only one end of the ring.

Jun 13, 2016· The top and bottom surfaces of every ring groove must be completely smooth so the ring has something to seal against. The vertical clearance between the ring and the ring land should be between .002-.004″, preferably on the tight side. More than this and the rings will leak. Less than this and the ring will not float in the groove freely.


The solution: groove grinders made by Herkules. Using deep pass grinding and contour grinding for grinding grooves in carbide rings achieves the highest shape accuracy and surface quality in very short machining times. A long table version of the machine allows for the machining of composite rolls.

May 28, 2021· As pressure increases above the ring and between the ring's inside diameter and the piston groove, the ring is forced downward and outward, creating a tight seal over a wide range of engine RPM. The primary job of the top ring is to serve as a compression seal. It also helps to protect the second ring from combustion heat.


Install the expander into the ring groove followed by the rails.
