摘要：一种牙轮钻头轴承密封系统，主要由牙掌轴承（1）、牙轮内孔（2）、弹性密封件、密封槽（3）组成。其中，弹性密封件采用主要由弹簧内圈（8）和密封外壳（9）组成弹簧蓄能密封圈。其内圈是由不锈钢类材料制作的金属弹簧，外圈是由高分子塑料制成的密封外壳。在密封圈截面内还可以填充一些物质，以防止泥浆堵塞密封圈，影响弹簧的弹性。密封圈内的填充物可选择低硬度耐高温的硅胶。密封外壳的前沿有内凸缘（6）和内、外密封唇（18，7）。内凸缘（6）用于固定弹簧内圈（8）。内、外密封唇分别与轴承密封槽的两个密封面接触，实现牙掌轴承与牙轮内孔之间密封的目的。密封外壳采用耐磨性好摩擦系数极小的高分子塑料制成。由此，提高了密封件适应钻头高速旋转的能力，延长了密封寿命。

摘要： A bearing seal assembly (110, 112, 114) seals a sealing gap (26) defined by a first race (10) and a second race (12) of a bearing (100). The bearing seal assembly includes a resilient seal (24) having a cross-sectional profile (58) that in exemplary embodiments is symmetric about at least one of a horizontal axis and a vertical axis, and which may be an X-shaped profile. The profile defines a flexing portion (55), and the resilient seal further has a first pressure-bearing side (57) and a second side (59) opposite the first pressure-bearing side. The flexing portion is configured to flex to form an energized seal that seals the sealing gap when a pressure is applied to the first side of the resilient seal. The bearing seal assembly may also include wear strip section (66) that has a removable blast shield (74) that protects the seal during a coating process, and subsequently is removed. A bearing assembly (100) may include the first race and the second race that define the sealing gap, and the described bearing seal assembly.

摘要： A pillow block bearing assembly for a drivetrain assembly of a work vehicle may include a pillow block housing defining a bearing cavity, a bearing disposed within the bearing cavity, and first and second sealing devices installed within the bearing cavity. Additionally, the drivetrain assembly may include a shaft received within the pillow block bearing assembly, with the shaft extending through the bearing such that an outer circumferential surface of the shaft directly contacts an inner circumferential surface of an inner race of the bearing at a bearing/shaft interface defined between the shaft and the bearing. Moreover, a sliding fit may be defined between the outer circumferential surface of the shaft and the inner circumferential surface of the inner race at the bearing/shaft interface such that the shaft is allowed to slide axially relative to the bearing when a given axial load is applied through the shaft.

摘要： An outer-ring-equivalent component (2) having an annular raceway surface (2a) on which rolling elements (5) roll is disposed on an outer circumference of a bearing (3). The bearing (3) is, for example, a retainer-equipped roller. Between the bearing (3) and a fixed member (7) located apart from the bearing (3) in an axial direction, a thrust washer (4) is interposed so as to be movable in the axial direction. A gap forming device (10) is provided which constantly forms a gap (11) between the thrust washer (4) and the outer-ring-equivalent component (2). For example, as the gap forming device (10), an axial width (J) of the bearing (3) is made larger than an axial width (G) of the outer-ring-equivalent component (2).
