摘要： A labyrinth type seal assembly having one or more controlled porosity elements retained in the labyrinth pathway between relatively rotatable seal elements. Preferably the controlled porosity elements are formed of open celled foam material such as polyurethane. The controlled porosity elements assist in preventing the ingress of contaminating solid or liquid materials, the loss of sealed materials and the flooding or overloading of drain ports.

摘要： A mounting for the road wheel of an automotive vehicle includes a spindle, a hub located around the spindle and inboard and outboard tapered roller bearings located between the hub and spindle where they are mounted in opposition. The cones (inner races) of the two bearings are separated by a spacer which at its ends is attached to the cones. The spacer holds the cones together within the hub so that the bearings and hub can be installed on and removed from the spindle as a unit. The spacer also establishes the setting for the bearings. In addition, the mounting has a seal located in the inboard end of the hub. The seal has lips which establish dynamic fluid barriers along the cone of the inboard bearing and along an adjacent sealing surface on the spindle without contacting the cone or spindle. The raceways and rollers for the two bearings have highly crowned profiles and the hub and the seal within contain an optimum amount of grease for lubricating the bearings.
摘要翻译：用于机动车辆的车轮的安装件包括主轴，位于主轴周围的轮毂和位于轮毂和主轴之间的内侧和外侧圆锥滚子轴承，在那里它们相对安装。两个轴承的锥体（内圈）由间隔件分开，间隔件在其端部附接到锥体。间隔件将锥体保持在毂内，使得轴承和轮毂可作为一个单元安装在主轴上和从主轴上移除。垫片还建立了轴承的设置。此外，安装件具有位于毂的内侧端部的密封件。密封件具有唇部，沿着内侧轴承的锥体并且沿主轴上的相邻密封表面建立动态流体屏障，而不接触锥体或主轴。两个轴承的滚道和滚子具有高度凸度的轮廓，轮毂和密封件包含用于润滑轴承的最佳润滑脂量。

摘要： The performance of a worm assembly seal is improved by (1) the use of a hardened steel worm with a bronze worm gear; (2) the use of a hardened steel worm and a bronze worm gear with a tribological coating on one or both of the worm thread or spiral and the gear teeth; 3) the use of a hardened steel worm and a bronze worm gear with a tribological coating on one or both of the input or output shaft or shaft sleeves; or (4) the use of a hardened steel worm with a bronze worm gear with a tribological coating applied to the worm thread, the gear teeth, the input and output shafts or shaft sleeves, or combinations thereof. In each of the three approaches, the worm, worm gear, and input and output shafts or shaft sleeves can have surface finishing treatments. Additionally, in each of the three approaches, carbon or carbon/nitrogen concentration gradients can be added to the worm. As can be appreciated, each approach builds on the prior approach to further improve seal performance, thereby reducing seal leakage and extending seal life.

摘要： A particle exclusion assembly designed to operate in an inclined position and to protect an associated sealing assembly. The assembly includes radially inner and outer relatively rotatable walls and axially inner and outer baffles and a rotary, controlled porosity, open-celled element which substantially fills the cavity between the two walls and the two baffles. The open-celled element controls the rate of movement of particulate material and restricted annular opening is provided to control ingress and egress of particulate material from the open-celled element.

摘要： A seal assembly (100) between an elastomeric seal component (110) and a surface (102) of a rotating component (104) which incorporates at least one micro-channel (106) having discrete branching elements (108, 108A) or micro-recesses (114). The micro-channels (106) are formed on either the surface of the rotating component (104) or the elastomeric seal component (110), and are configured to provide a uniform and unidirectional wear surface. The micro-channels (106) permit a controlled amount of lubricant to flow to the elastomeric seal region (R) area while creating a barrier to prevent lubricant axial migration beyond the elastomeric seal region (R). The controlled lubrication reduces seal wear, extends the seal life, and results in a reduced chance of leakage if the elastomeric seal component (110) is misaligned relative to the rotating component surface (102).
摘要翻译：在弹性体密封部件（110）和旋转部件（104）的表面（102）之间的密封组件（100），其结合有至少一个具有分立的分支元件（108,108A）或微型（114）。微通道（106）形成在旋转部件（104）或弹性体密封部件（110）的表面上，并且被构造成提供均匀且单向的磨损表面。微通道（106）允许受控量的润滑剂流动到弹性体密封区域（R）区域，同时产生阻挡层以防止润滑剂轴向迁移超出弹性体密封区域（R）。如果弹性体密封部件（110）相对于旋转部件表面（102）不对准，则可控制的润滑减少密封件磨损，延长密封寿命并且导致泄漏的可能性降低。

摘要： A bearing isolator seal having a shaft seal assembly that includes a stator housing having an inner radially extending face with an annular flange of substantially frusto-conical shape that extends from a larger diameter end that is fixed to the inner radially extending face to a smaller diameter free end, and a rotor having a peripherally extending radial flange of substantially frusto-conical shape that is provided with a smaller diameter end that is fixed to a hub of the rotor, a larger diameter free end, and a contact sealing surface therebetween, the free end being biased into contact with the inner radially extending face of the stator housing and the contact sealing surface being biased into contact with the free end of the annular flange of the stator housing under static seal conditions, the rotor being constructed in a manner causing these areas of contact to be broken under the effect of centrifugal forces generated by rotation of the rotor with the shaft. In accordance with another feature of the preferred embodiments, drain ports are provided at a radially inner side of the fixed end of the annular flange of the stator housing, and radially extending V-grooves are provided in an axial end surface of the rotor so as to cause lubricant to be propelled radially outwardly against the angled annular flange of the stator housing, along which it is cause to flow to and through axially extending holes forming the drain ports under dynamic sealing conditions.
