An improved design and method is disclosed that uses a novel nesting linear slide which incorporates machine tool slides or ways into a structural member. The design simplifies the fabrication and assembly of components requiring accurate sliding alignment, such as milling machine bases, saddles, tables and columns. Due to the use of the single piece, which replaces multiple pieces in the prior art, fabrication and assembly costs are also significantly lower. The invention also enables a method of construction utilizing the novel single shape component which simplifies the assembly of machines requiring sliding surfaces with accurate alignment. The invention essentially comprises a single structural element that includes both male and female sliding members. By nesting two of the single structural elements it is possible to create sliding joints for machine tool bases, saddles, tables, and columns, as well as a wide variety of other sliding joints, in an extremely cost-effective manner. The simplicity and low cost of the method will be especially advantageous in the manufacture of small machine tools and other machines intended for higher volume production.

A method for manufacturing a transmission device that includes a casing, and a rotary part rotatably guided inside the casing by means of a first bearing and a second bearing. The method includes axially moving a preloading element in a first recess until it bears axially against the first bearing in the first direction, and then applying a force to the preloading element until the applied force reaches a set value and the preloading element reaches a preloading position in which a predetermined axial preloading force is applied by the preloading element and the axial bearing surface of the casing to the first bearing and the second bearing, respectively. The preloading element is attached to the casing in in the preloading position.

A journal foil bearing system includes a journal housing member including a journal housing wall that is disposed about a bore that extends along an axis. The journal housing wall has an inner diameter surface that faces the bore. The journal housing wall locally along the inner diameter surface has a first relief region. A shaft is disposed within the bore and is supported for rotation. A biasing foil member includes at least one biasing foil received within the bore and disposed radially between the journal housing member and the shaft. A top foil member includes at least one top foil disposed within the bore radially between the at least one biasing foil and the shaft. The biasing foil is disposed circumferentially along the inner diameter surface and the first relief region.

A rolling bearing includes an inner ring, an outer ring, a plurality of balls, and a cage that holds the balls. The inner ring is a rotating ring, and the outer ring is a fixed ring. An annular groove for creep suppression is formed in a fitting surface of the rolling bearing that is fitted on a mating member to which the outer ring is attached. The annular groove has a groove main body portion and inclined groove portions located on opposite sides of the groove main body portion in an axial direction and formed to be shallower than the groove main body portion such that the depth of each of the inclined groove portions increases toward the groove main body portion. The inclined groove portions come into contact with the mating member when the outer ring is elastically deformed by a radial load received from the balls.

A mount surrounding a rigid body within an enclosure, is provided herein. The mount includes: a first pair of a first pin and first spherical bearing, wherein the first pin is movable within the first spherical bearing while being in contact with the rigid body such that two degrees of freedom (DOF) restriction enable a displacement of the rigid body; a second pair of a second pin and second spherical bearing, wherein the second pin is movable within the second spherical bearing while being in contact with the rigid body such that two DOF restriction enable a displacement of the rigid body; and a third pair of a third pin and third spherical bearing, wherein the third pin is movable within the third spherical bearing while being in contact with the rigid body such that two DOF restriction enable a displacement of the rigid body.

A mounting tool and a method for mounting a wheel bearing assembly, having an inner ring flange and an outer bearing ring, into a bearing seat of an axle body of a vehicle are disclosed. The mounting tool includes a supporting member, two L-shaped holding members, which can be fastened at various positions along the supporting member, and at least one securing means for fastening the L-shaped holding members to the supporting member. The holding members each have a foot section with a recess, the foot sections being insertable in an intermediate space between the inner ring flange and the outer bearing ring in order to engage the outer bearing ring. Each recess has a shape configured to apply an evenly distributed pressure to outer bearing rings of several different dimensions. Hereby a flexible and versatile mounting tool is provided.

A toolkit for mounting a bearing onto a seating includes an adapter sleeve radially interposable between the inner ring and the seating and having a tapered portion configured to mate with a tapered bore of the inner ring and a threaded portion configured to extend away from the bearing, a hydraulic nut having a threaded bore and an axially moveable piston, a hydraulic pump configured to increase a hydraulic pressure inside the hydraulic nut, a driving tube configured to be interposed axially between the side face of the inner ring of the bearing and the piston, and a reaction sleeve configured to be interposed between the hydraulic nut and the adapter sleeve and including a first threaded portion configured to engage the threaded portion of the adapter sleeve and a second threaded portion configured to engage the threaded bore of the hydraulic nut. Also a method of using the toolkit.

Methods and systems for surge control in a compressor system. A recirculation valve position may be actuated in response to identified conditions of potential surge, determined from a compressor map. Recirculation valve position may be controlled by calculating distance of current operating state to a surge line and using proportional integral control to manage the distance. Compressor speed command may be derated in response to identified surge, determined from one of speed fluctuations of the compressor speed, or variance of a compressor speed tracking error.

One or more techniques and/or systems are disclosed for a connecting rod that can comprise a body configured to house an internal lubricant reservoir. The reservoir can house and supply lubricant to bearings coupled with the rod. These bearings may be in fluid communication with the internal reservoir, which can in-turn provide lubricant to the bearings. The rod or bearings may comprise at least one lubrication port fluidly coupling the lubrication port with the bearing, to facilitate the flow of lubricant from the reservoir to the bearing.
