    • An earth boring bit has a bit body having a depending bearing pin. A cone has a cavity rotatably mounted on the bearing pin. A seal groove formed in the cavity of the cone. An elastomeric seal ring is located within the groove and forms a seal between a base of the groove and the bearing pin. The seal ring has two side surfaces, each spaced from one of the side walls of the groove by a clearance. Elastomeric protuberances protrude from each of the side surfaces of the seal ring for non-sealing contact with one of the side walls of the groove.
    • 地镗头具有一个具有从动轴承销的位体。 锥体具有可旋转地安装在轴承销上的腔体。 形成在锥体的空腔中的密封槽。 弹性密封环位于凹槽内,并在凹槽的基部和轴承销之间形成密封。 密封环具有两个侧表面,每个侧表面与沟槽的一个侧壁间隔开一个间隙。 弹性突起从密封环的每个侧表面突出,用于与槽的一个侧壁非密封接触。

    • An earth boring bit has rotating cones with two lubricant passages to increase bearing capacity and cause lubricant circulation. A lubricant reservoir in the body supplies lubricant to passages between the cone and bearing pin. A pressure compensator equalizes lubricant pressure to the exterior of the bit. A first passage leads from the reservoir to the upper side of the bearing pin. A second passage leads from the reservoir to the bearing pin at a point from 185 degrees to 225 degrees as seen from an inner end of the bearing pin. This point is located in a diverging region 51d of an annular clearance surrounding the bearing pin.
    • 地球钻头具有带有两个润滑剂通道的旋转锥体,以增加承载能力并引起润滑剂循环。 体内的润滑剂储存器向锥体和轴承销之间的通道提供润滑剂。 压力补偿器将润滑剂压力与钻头的外部相等。 第一通道从储存器引导到轴承销的上侧。 第二通道从轴承销的内端看,从185度到225度的位置从储液器引导到轴承销。 该点位于围绕轴承销的环形间隙的发散区域51d中。
