Typical Seal structure
As shown in Figure 1, the typical bimetal seal which is located in the chamber between the cone and the bearing consists of a pair of metal rings and a pair of rubber rings. The two rubber rings always keep the faces of the two metal rings in contact, thereby forming a reliable seal and also playing the role of a radial seal. The function of the cone bit bearing seal is to prevent mud, cuttings, and other substances from entering into the bearing and to maintain the grease acting as lubricant.
Figure 1. Cone bit bearing seal: 1-shaft contour, 2-static rubber ring, 3-static metal ring, 4-moving metal ring, 5-moving rubber ring, and 6-cone inner contour.
New seal structure
