Abstract: The diametral clearance of an aperture of a bearing is measured by an apparatus which includes a mounting for placing both the bearing and an associate pivot in axial relation with each other along an axis of alignment and positioning devices for positioning the pivot in relation to the bearing. The positioning devices include axial direction positioning devices for adjusting the pivot in each of two mutually perpendicular axial directions transverse to the axis of alignment to locate an approximate center of bearing clearance and for adjusting the pivot from the approximate center of bearing clearance in each of the mutually perpendicular axial directions until the pivot displaces the bearing in the corresponding direction.

Abstract: A probe for inspecting contoured surfaces by transmitting and receiving eddy currents includes a shaft disposed in spatial relationship with the contoured surface and a pivotal probe manipulator rotatably mounted on the end of the shaft and having a critical dimension including the location of the pivot point and the width of the probe manipulator and spring means urging the probe manipulator against the contoured surface so that the probe travels along the surface and rotates substantially .+-.90 degrees relative to the shaft.

Abstract: A device for measuring end play between a vehicle spindle and a wheel hub. A rotary thrust rod has a swivel connection with a housing threaded onto the spindle, such that the rod applies a pushing or pulling force to the spindle, depending on the direction of thrust rod rotation.

Abstract: An apparatus for use with a device including a housing having a wall surface, and including a pinion and bearing carrier assembly having a first surface and a second surface, and also including a shim or shims located between the first surface and the wall surface, the apparatus determining the required thickness of the shim or shims in order to space the second surface a predetermined distance from the wall surface, the apparatus comprising a frame including a reference point, and a surface adapted to support the second surface of the assembly, a member including a surface adapted to engage the first surface of the assembly, a mechanism for moving the member relative to the frame so as to move the member surface into and out of engagement with the first surface of the assembly, and an arrangement for indicating the location of the member relative to the reference point.

Abstract: A gaging tool for checking the alignment of spaced apart holes located on a common axis, having particular utility for checking the alignment of bearing seats on half round yokes for universal joints. A pair of gage bushings are secured in the bearing seats by retaining straps. An alignment bar is passed through the internal gage bore of one of the bushings. When the bearing seats or holes are in alignment, the alignment bar will pass into the other of the pair of gage bushings.

Abstract: An apparatus mechanically actuates GO ring gauges and NOGO ring gauges to check whether inner and outer diameters of hollow, cylindrical-shaped products such as bushes B/G are within fit tolerances, thus automatically distinguishing between acceptable and unacceptable products.

Abstract: An apparatus for use with a device including a wall surface, and a removable, rotatable shaft having thereon a reference point and a bearing assembly, the bearing assembly including a surface supported by the wall surface with a shim between the bearing assembly surface and the wall surface, and with a fixed distance between the wall surface and the reference point when the bearing assembly is axially loaded in the device, the apparatus being for measuring the required thickness of the shim without inserting the shaft into the device, and the apparatus comprising a mechanism for axially loading the bearing assembly with the shaft out of the device, and a gauge rod for measuring the existing distance between the bearing assembly surface and the reference point.

Abstract: A device for measuring interference and wall thickness of a half cylindrical plain bearing includes a bearing support block provided with a substantially semi-cylindrical shaped recess for receiving the plain bearing, a pressing mechanism for closely pressing the plain bearing against the recess, a substantially semi-columnar shaped wall thickness measuring head having a smaller outer diameter than the inner diameter of the plain bearing when it closely contacts with the recess, and a positioning mechanism for establishing a predetermined positional relationship between the recess and the wall thickness measuring head upon measurement. The bearing support block carries a detector or detectors for measuring interference of the half cylindrical plain bearing, and the wall thickness measuring head incorporates measuring instruments such as air micrometers.

Abstract: A measuring apparatus for measuring the interference or height of semicylindrical articles such as shell-type half bearings or the like in which the articles to be measured are adapted to be disposed in a shape-conforming cavity of a bearing cap with one parting edge surface of the bearing being supported by the framework of the apparatus. A reciprocable gaging block incorporating a gaging surface is movable to and from a measuring position and a clearance position by means of a motor and cam carrier assembly which is biased toward the gaging block under a preselected load and the eccentric cam thereon effects an intermittent reciprocation of the gaging block to and from the measuring position. Biasing means are provided for continuously biasing the gaging block toward a nonmeasuring position. A probe is provided for sensing the interference or height of a bearing being measured in response to the disposition of the gaging surface relative to the bearing cap when the gage block is in the measuring position.

Abstract: A measuring process for evaluation of the machining capability or quality of multi-spindle rotary machining or turning unit utilized for the production of preferably rotationally-symmetrical workpieces which are to be finished on both sides, and for the intermediate and/or final evaluation of workpieces which are finished in that manner. Furthermore, the invention also relates to a measuring installation for the implementation of this measuring process.

Abstract: A gauge for measuring the clearance between the bottom surface of the body side bearings of a rail car and the subjacent top surface of the respective truck side bearing rollers includes a central vertical frame and a horizontal cross beam carrying on each of its outer extremities a vertically movable graduated blade. Telescoping arms on opposite ends of the cross beam enable the gauge to be used on different kinds and sizes of rail cars and cabooses; and a missing side bearing adapter is provided so that gauging can proceed even though either or both of the side bearings are missing. For truck plant and body plant use special indicia are provided.
