A torque-resistant dual face seal includes a seal ring (110, 112) having an L-shaped cross-section including an axially-extending flange (140, 142) and a radially-extending flange (126, 128), the seal ring including an annular seal face (118, 120) and an annular loading surface (134, 136). The seal ring includes a plurality of deformations (138) formed in a spaced apart arrangement circumferentially around the axially-extending flange. An axial cross-section through the axially-extending flange and intersecting one of the plurality of deformations includes a stepped geometry. The plurality of deformations allows a load ring (114, 116) to squeeze into the plurality of deformations to increase a surface area contact between the seal ring and the load ring.
一种抗扭矩双面密封件包括密封环(110、112),密封环具有包括轴向延伸凸缘(140、142)和径向延伸凸缘(126、128)的L形横截面,所述密封环包括环形密封面(118、120)和环形加载表面(134、136)。所述密封环包括以沿周向围绕轴向延伸凸缘的间隔开布置而形成的多个变形部(138)。穿过轴向延伸凸缘并且与所述多个变形部中的一个相交的轴向横截面包括阶梯形几何形状。多个变形部允许负载环(114、116)挤压到所述多个变形部中以增加密封环与负载环之间的表面面积接触。
