Compact Wedge-Profiled Sealings for Shafts and Hydro-machine Flanges
Abstract
The paper considers some compact wedge-profiled seals for shafts and flanges of hydraulic machines made from light and durable material. Studies of the narrow-edged metal seals show that high tightness can be obtained with a minimum width of the contact. Under the high pressure of working fluid on the cylindrical surface, the compact wedge-profiled seals sag and completely adhere to the cones of seats, with ends slipping across the flat surfaces with no loss of integrity. The hollow portion available in the elastic characteristic enables us to reduce the contact stress (pressure) when compact wedge-profiled seals are used in movable joints, reducing friction and their wear.
