摘要： A bearing sealing device comprises a middle ring having peripheral channel adapted to partially accommodate an annular sealing means that exerts a sealing action against a rotating member to be protected, and against the inner surface of the encircling casing within which the rotating member is located, and an lower ring which, by being urged against the middle ring, insures a sound tightness by virtue of the contact of one annular surface thereof with an opposing surface of the first annular element; a spacer means insertable into the first annular element, which spacer is retained in place by the lower ring. It is provided with a lower cylindrical recess partially accommodating a second annular seal which is adapted to exert a sealing action on the central shaft on which the rotating member being protected is mounted.

摘要： This invention relates to an improved pillow block characterized by a cast body containing a main bore for housing an antifriction bearing and cast bolt-receiving slots for mounting same and for attaching endplates thereto that do away with the need for drilled and tapped holes. The endplates are cut from common sheet materials and gang-drilled to provide the apertures that accept the bolts used to assemble same onto the opposite faces of the body with an O-ring therebetween to establish a fluid-tight seal. In like manner, a hole cutter is used to cut rather than drill a central hole for passing the rotating element to be journalled in the bearing.

摘要： An improved pressure compensator for earth boring drill bits for minimizing the pressure differential between the lubricant and the well bore. A flexible diaphragm is located in the lubricant reservoir for separating the lubricant from the borehole fluid. The diaphragm is positioned in the reservoir so that a substantial void space exists on the borehole fluid side of the reservoir. A retainer holds the diaphragm in this position, requiring a positive lubricant pressure to stretch the diaphragm in order to fill the void space. For lubricating the bit, the lubricant is introduced under pressure sufficient to stretch the diaphragm. The lubricant pressure is then released, allowing the compensator to return to its original shape which in turn causes the excess lubricant to be expelled. This assures complete filling and a desired void space.
摘要翻译：用于钻孔钻头的改进的压力补偿器，用于最小化润滑剂和井眼之间的压力差。柔性隔膜位于润滑剂储存器中，用于将润滑剂与钻孔流体分离。隔膜位于储存器中，使得在储存器的钻孔流体侧存在实质的空隙空间。保持器将隔膜保持在该位置，需要正的润滑剂压力来拉伸隔膜以填充空隙。为了润滑钻头，在足以拉伸隔膜的压力下引入润滑剂。然后释放润滑剂压力，允许补偿器返回到其原始形状，这又导致多余的润滑剂被排出。这确保完全填充和所需的空隙。

摘要： An axle is disclosed having a housing defining a lubricant reservoir. A shaft extends through a bore in the housing and is supported by two bearings within the bore. The shaft has a radially extending surface which partially defines a lubricant chamber for pressurizing and pumping lubricant. The housing has a lubricant passageway in communication with the lubricant chamber. A seal is positioned within the lubricant chamber and has a lip which contacts the radial surface.

摘要： A downhole drilling motor, e.g. a turbodrill, which is connected to a string of drill pipe has a rotating shaft for driving a drill bit which may be a rotary bit or a high speed solid head diamond bit. The turbine section has rotor and stator blades which are crescent shaped in cross section with each blade having an exit angle of 14.degree.-23.degree. for maximum turbine efficiency. The drilling motor may alternatively be a positive displacement motor. The bearing shaft is provided with chevron rotary seals positioned below the rotary bearings carrying both radial and vertical thrust. Fluid lubricant fills the space from the rotary seals to a predetermined level above the bearings. A piston seals the lubricant chamber and is pressurized by drilling fluid (i.e. mud) flowing through the tool. A layer of lubricant fluid overlies the first piston and has a second piston covering said fluid and transmitting pressure from the drilling fluid to the lubricant fluid surrounding the bearings. The drilling mud is divided into two streams, one of which rotates the drill bit, and the other of which passes through the drill bit. The pressure drop across the drilling motor equals the pressure drop across the drill bit, thus balancing the pressure on the bearing seals.

摘要： A self-loading auger scraper has a sealed auger supporting bearing assembly that includes a fixed lower housing secured to the floor of the scraper bowl and an upper housing rotatably mounted in bearings in the lower housing. An auger drive means is supported on a cross beam at the top of the bowl; and the upper bearing housing and the drive means have generally coaxial opposed square stub shafts which are loosely but non-rotatably engaged by square sockets in the bottom and top of an auger shaft to provide slip connections. The length of the auger shaft is such as to permit the auger to float while maintaining the slip connections.
