O-Rings |
||
| O-rings are primarily used for sealing.
Another application is the use as drive belts. As a seal, an O-ring is
a means of preventing an unwanted escape of fluid or pressure. Types of
seal applications include: ______________________________________________ ______________________________________________ Static seal The mating gland parts are not subject to relative movement ______________________________________________ ______________________________________________ Dynamic seal 1. Reciprocating relative motion along the shaft axis 2. Oscillating: movement around the shaft axis relative to the other member 3. Rotary: movement around the shaft axis in one direction only 4. Seat: mechanical distortion of the O-ring around a shaft in order to create the seal ______________________________________________ ______________________________________________ Pneumatic seal Similar to any of the ones previously described except it is used with a gas or a vapor rather than a liquid ______________________________________________ ______________________________________________ Vacuum seal Seals a vacuum chamber or area |
