一种无填料轴承密封的研制

his research according to stationary flow concentric revolving the cylinder and the quality of Couette stream, establish the flowing model of inside and outside of seal. And we research and manufacture a kind of bearings seals-less. The principle of this seal makes full use of press bad between the inside and the outside seals to overcome liquid permeate. Liquid is prevented from outside the bearings, it improves seal usage condition, reducing wear and tear and lowering maintaining expenses, coming to economy energy.
