Web4 de jul. de 2016 · Dynamic characteristics of the herringbone grooved gas journal bearings (HGGJB) under fluid-structure interactions are systematically investigated using the finite element method. Stability and bearing capacity of the HGGJB are estimated and compared with those of the plain gas journal bearings (PGJB). Influences of the …
Spiral groove bearings (also known as Rifle bearings) are self-acting (journal and thrust), or hydrodynamic bearings used to reduce friction and wear without the use of pressurized lubricants. They have this ability due to special patterns of grooves. Spiral groove bearings are self-acting because their own rotation builds up the pressure needed to separate the bearing surfaces. For this reas…
