Abstract: A steering column assembly comprises an outer jacket extending along an axis and defining a central opening for placing a steering shaft and a bearing assembly. A bearing retainer is located in the outer jacket for axially retaining the bearing assembly in the outer jacket. The bearing retainer comprises a first surface spaced from a second surface by an outer edge and an inner edge. The inner edge defines an opening for placement of the steering shaft. The bearing retainer includes a first spring finger extending from the first surface away from the second surface at an angle and a second spring finger extending from the second surface away from the first surface at an angle.

Abstract: A steering column device includes a steering shaft; and a steering column. The steering column includes a housing, a cover, and a sealing member. The housing includes an inclined portion having an inclined surface with an inside diameter increasing from a first side to a second side, the inclined surface contacting the sealing member from the first side. The cover includes a facing portion having a facing surface contacting the sealing member from the second side, and an insertion portion having an outer peripheral surface contacting the sealing member from an inner peripheral side. The sealing member is accommodated in an accommodation space defined by the inclined surface, the facing surface, and the outer peripheral surface. An escape space continuous with the accommodation space is provided between the housing and the cover, the escape space being located closer to the first side than the inclined surface is.

Abstract: A seal device, which accommodates axial displacement between a housing and shaft of an item of rotating equipment, includes a stator which locates into the housing of a piece of rotating equipment. A first rotor locates on the shaft of the rotating equipment and a second rotor is rotationally coupled to the first rotor with the first rotor being permitted to axially float with respect to the second rotor. The device provides sealing integrity when the shaft is both idle and operational. The sealing device may be used, for instance, in a double ended centrifugal pump where shaft displacement occurs from thermal expansion.

Abstract: Two coupling members are provided in respective butting end faces thereof with annular recessed portions surrounding respective fluid channels thereof and having annular projections each formed in a bottom face of the recessed portion. A gasket comprises a sealing portion having an outside diameter smaller than the diameter of the recessed portions and is positioned between the projections of the coupling members, and a guide has an outside diameter permitting the guide to be fitted into the recessed portions and positioned externally of the sealing portion. The butting end faces of the coupling members are movable into contact with each other when the coupling is tightened up properly. The sealing portion has an annular groove formed in an outer periphery thereof, and the sealing portion and the guide are connected together by a snap ring fitted in the annular groove.

Abstract: The assembly includes rotor and stator elements each having an inclined plane or surface juxtaposed to each other. This is a metallic assembly and the rotor and stator also have juxtaposed cavities. The stator cavity being of sufficient size to accommodate a sealing member. The inclined surfaces are flexed with the inclined plane or surface of the rotor forced over the inclined plane or surface of the stator to lock the rotor and stator together with the sealing member enclosed between the rotor and stator. The sealing member does not rotate with the stator. The seal contains at least one labyrinth formed with the rotor and stator, are adjacent each other and lock together.

Abstract: A mount construction for a bearing seal is capable of easily and surely installing the bearing seal in a bearing and, after installation, developing a stable seal performance by suppressing an extracting force. The bearing seal, formed by disposing an elastic member having a lip part on one side face of a reinforcement ring, is press-fitted into a ring body or radially reduced ring body in a state where the lip part is bent in a direction away from the outer peripheral edge of the reinforcement ring on the elastic member side of the bearing seal. While maintaining this state, the bearing seal is extruded from the inside of the ring body or the radially reduce ring into the bearing with care so that the lip part is not caught between the reinforcement ring and the bearing is installed on the bearing.

Abstract: The invention relates to a method and apparatus for assembling in an automated manner a sealing profile on an inner door for refrigerators. The method comprises the stages of: a) providing said profile (1) in the form of a frame welded at the corners, b) stably resting said frame on a support (10), c) gripping said section (4) along all the sides of said frame using engaging means (12) so as to perform said elastic splaying, d) retaining said sections (4) in the splayed position, e) positioning said inner door (31) on said sections (2) of said profile base, f) releasing said sections (4) so as to allow the elastic return of the profile base onto the edge of the inner door, g) extracting inner door and profile thus assembled from said support.

Abstract: A seal arrangement for providing a seal between a nuclear reactor in-core instrument housing and an instrument contained within the housing includes a lower seal assembly surrounding an outer portion of the in-core instrument housing, an upper seal assembly surrounding an outer portion of the in-core instrument, a seal housing enclosing the lower and upper seal assemblies, and lower and upper compression assemblies positioned on respective ends of the seal housing. The compression assemblies each include a drive nut and a compression collar. The compression collars engage and apply an axial load on the seal assemblies to maintain a reliable seal between the seal housing and the outer portion of the in-core instrument housing, and between the seal housing and the outer portion of the in-core instrument.

Abstract: The hole plug includes a peripheral planar ledge with a wall formed perpendicular therewith. A gasket seats within the intersection of the planar ledge and the wall. The gasket includes inwardly extending tabs (or “dogs”) which extend into corresponding pockets (or “doghouses”) formed in the wall. This causes the gasket, which is initially provided in a non-tacky state, to be mechanically secured to the hole plug during shipment and assembly prior to installation.

Abstract: A retainer for the installation of a seal or other component within a machine assembly including concentric first and second machine parts. One of the machine parts is formed as including a gland having a forward end wall and first and second peripheral walls. The first peripheral wall is spaced-apart a first distance from the other machine part and extends intermediate the forward end wall and an open rearward end, with the second peripheral wall being formed contiguously within the first peripheral wall intermediate the forward end wall and the open rearward end. The second peripheral wall is spaced-apart a greater second distance from the opposing machine part, and terminates at a rearward end wall. The retainer has an annular body configured to be receivable intermediate the first and second machine parts.

Abstract: Improved shield designs for ball bearing based spindle motors that exhibit improved containment of grease and the base oil within the bearings at accelerated conditions of temperature and speed is disclosed. Improved shield designs are provided at the shield OD contact area, the use of an impervious shield material, the use of barrier films, shield/bearing designs that use tortuous paths and labyrinth schemes for reducing the oil and grease loss from the shield ID gap of DASD spindle ball bearings, and improved stainless steel shield designs.

Abstract: An inverted strut damper includes an external cylinder which has an expanded midsection and a vertically moveable damper tube arranged concentrically within the outer cylinder. The outer cylinder and tube arrangement form a lubricating oil supply reservoir. Disposed at a top and a bottom of the outer cylinder is a respective oil seal and bearing arrangement. The upper bearing is adjacent to the lubricating oil reservoir and upon upper movement of the damper tube, oil is supplied to the upper bearings and seal.
