Abstract: A method for mounting on a shaft extending through a housing a preloaded rolling bearing assembly incorporating first and second rolling bearings capable of supporting axial load, involves mounting the outer race rings of both bearings in axially fixed positions in the housing, mounting the inner race rings with a shrink fit on the shaft and with rolling bodies disposed between the inner and outer race rings, and introducing in the interface between the inner envelope surface of the inner race ring of the second bearing and the shaft a pressure medium to create a thin medium film in the interface for allowing the inner race ring of the second bearing to be axially displaced on the shaft. An axial force is then applied to the inner race ring of the second bearing and the axial force thus applied is measured. The pressure medium is then drained from the interface between the inner race ring and the shaft when a predetermined axial force is reached, whereupon the axial force is relieved.

Abstract: An apparatus for supporting a roll mantle of a roll for a paper machine or equivalent in a lateral direction, in particular in the direction transverse to a principal loading direction, such as the nip plane. The roll mantle is rotatingly supported on a stationary roll axle, e.g., by support and loading members, and is displaceable in relation to the axle substantially in the principal loading direction. The roll mantle is also supported on the roll axle radially by glide bearing elements acting in opposite radial directions so that, when the roll mantle is displaced in the principal loading direction, the movement of the roll mantle is guided to take place along a predetermined path.

Abstract: An assembly system comprises a supply jig for holding and positioning a plurality of parts one by one, a supply center for inserting a plurality of parts into the supply jig, a plurality of assembly centers for taking out the parts from the supply jig and assembling the parts into products in parallel processing, carrier conveyor for carrying the supply jig from the supply center to the assembly centers and return conveyor for returning the supply jig from the assembly centers to the supply center. The supply jig supplies the common parts which are required in all of the assembly centers, while each of the assembly centers comprises individual supply means for supplying a non-common part. Thus, this system can cope with assembling various types of products simultaneously, and can eliminate line stoppage upon occurrence of a trouble or for periodic inspection in any one of the centers, thereby production capability is improved.

Abstract: An outer ring of an axle bearing is heat-treated and a through hole can be formed quickly and reliably. The outer ring has raceways on its inner periphery along which rolling elements roll. A through hole for mounting an antilock brake sensor is formed in the outer ring to extend from its outer periphery to the inner periphery. A plug is inserted into the hole thus formed. After hardening the raceways, the plug is pulled out of the hole. Since the hole is formed before hardening the raceways, it can be formed easily by drilling with an ordinary carbon steel tool. Since the raceways are hardened after inserting the rod-shaped metal plug into the hole 9, the heat produced during hardening will disperse through the plug. It is thus possible to prevent shoulder portions of the raceways from melting due to overheating.

Abstract: A catalytic exhaust treatment device for an automotive vehicle includes a generally cylindrical substrate having a support seal at either end and with each of the support seals encircling an end of the substrate, and an intumescent mat applied to the cylindrical surface of the substrate, with the mat extending between the support seals. The catalyst further includes a cylindrical container having an inside diameter sized so as to compress the support seals and the mat such that the seals and mat are maintained in contact with the substrate and the container.

Abstract: The end surface 2e of the press-fit portion 2c of the axle 2 is machined with high precision to serve as a reference surface for measuring the negative bearing clearance upon completion of the assembly. The inner ring 3 is press-fitted on the press-fit portion 2c of the axle 2 and is fixed in position by the nut 6 screwed on the threaded portion 2d of the axle 2. In this axle bearing assembly, the inner ring 3 abuts against the shoulder portion 2d of the axle 2 with no clearance defined therebetween, and the negative bearing clearance is assured.

Abstract: A process is provided for making a painted end frame assembly of the type used in a bed, crib, or cradle. Components of the end frame assembly are first formed and a selected color of paint is applied to each component to produce a multi-colored end frame assembly following later assembly of the components. In one embodiment, a process is provided for making a painted end frame assembly with multi-colored spindles.

Abstract: A method to automatically align internal splines (20) of a torque converter (16) to mating external splines (18) of a transmission subassembly (14) during the assembly of the torque converter (16) to the transmission subassembly (14). The apparatus includes a robotic end effector assembly (26) coupled to an arm (22) of a robot (24). The end effector assembly (26) includes a counterbalance mechanism, such as spring assemblies (62) and a position sensor (64) that provide for a reduced effective weight of the torque converter (10) to allow the splines to align and detect if the splines are not properly aligned. Upon sensing non-engagement, robot (24) lifts, rotates and lowers the torque converter (16) until the position sensor (64) detects alignment of the mating splines.

Abstract: A tool for installing and aligning a bearing cap in a universal joint so as to position an end surface of the bearing cap a predetermined distance above the outer surface of the arm of the end yoke is generally cup-shaped, including a generally flat, circular end portion having a hollow cylindrical skirt portion. The skirt portion defines an inner diameter which is slightly larger than the outer diameter of the bearing cap. The skirt portion also defines an axial length which is equal to the desired predetermined distance. A cut-out may be formed in a portion of the tool to receive a spring tab or other axial retaining structure for the bearing cap. Also, one or more apertures may be formed in the end portion of the tool to receive anti-rotation protrusions formed on the end surface of the bearing cap. The universal joint is assembled by initially disposing the tool over the end surface of the bearing cap such that the inner surface of the end portion abuts the outer end surface of the bearing cap.

Abstract: A double-containment piping assembly has two anchor supports, and at least one elbow fitting with an outer elbow section and an inner elbow section received within the inner elbow section. A first leg having a first inner pipe received within a first outer pipe is coupled between an anchor support and the elbow fitting. A second leg having a second inner pipe received within a second outer pipe is coupled between the other anchor support and the other side of the elbow fitting. First flexibility supports are mounted on either side of the elbow fitting, and permit axial and lateral movement of the inner pipe relative to the outer pipe in the areas of the elbow. First axial-guiding supports, which permit axial movement of the inner pipe relative to the outer pipe, but prevent lateral movement of the inner pipe, are each mounted a minimum distance from the elbow fitting between the inner and outer pipes.

Abstract: A high precision mounting method for linear guide rails is performed with the steps of: fixing the first linear guide rail to a first predetermined position while pressing the first linear guide rail against the reference surface of the mounting jig, disposing the mounting jig at a second predetermined position so that a section shape of the reference surface of the mounting jig in a longitudinal direction thereof is symmetric with respect to a center line between the first and second linear guide rails, and fixing the second linear guide rail to the mounting bed while pressing the second linear guide rail against the reference surface of the mounting jig disposed symmetrically. The mounting method is capable of mounting the linear guide rails in a short time.
