A gauge for setting. a pair of tapered roller bearings that are mounted in opposition has a base to which one of the races for one of the bearings is fitted remote from the location that it normally assumes. In addition, the gauge has male and female elements which slide on the base independently of each other and a spring for urging the elements apart. The spring urges one of the elements against a conical envelope on the detached race and the other element against a conical envelope formed by the tapered rollers around the other race that is in its normal operating position. Sensors measure the strain in the spring, and from the strain one can calculate the distance between like diameters on the conical envelopes. The measurement derived from the gauge together with the desired setting for the bearing enables one to calculate the thickness of a spacer which will provide the desired setting for the bearings.

A pair of tapered roller bearings, which are located between two machine components, such as a pinion shaft and its carrier, to enable the one component to rotate relative to the other one, is set to a desired dimensional preload with the aid of a gauge and the force preload in the bearing is determined to verify that it is within acceptable limits. The gauge is interposed between a raceway and rolling elements of the second bearing to measure the size of a spacer required to give the two bearings the correct dimensional preload. The gauge also exerts a known axial force on the bearings, and while that force is maintained, the torque required by the bearings is measured. That torque divided by the axial load gives a torque signature. Thereafter, the gauge is removed, the spacer is selected and installed, and the bearings are installed in their operative positions. The spacer sets the bearings with a desired dimensional preload.

A setting gauge (G) determines the thickness of a spacer () which gives the correct setting for a pair of tapered roller bearings (B, B) that are mounted in opposition to accommodate relative rotation between machine components (S, H). The gauge has a base () which at one end fits against a surface () to which the spacer is to be applied, and at its other end holds one of the races () of the bearing (B) remote from the other race () which remains in its operating position. In addition, the gauge has a pair of gauge elements (), one of which fits against a conical envelope along the remote race and the other of which fits against an identical conical envelope on the race which remains in its operating position, in effect, projecting the conical envelope defined by the in-place race out of the bearing to a remote location so that measurements may be taken from the bearing. The race which is remote during the measurements has a cylindrical surface () which is configured to fit another cylindrical surface () on one of the machine components (H) with an interference fit, and the gauge also measures the diameters of the two cylindrical surfaces so that the magnitude of the interference fit may be ascertained and its effect on the bearing compensated.

A modified temperature compensation signal (110) is provided in a temperature compensated crystal oscillator (TCXO) circuit (100) in the following manner. A temperature dependent current generator (104) produces a temperature compensation signal (108) whose amplitude changes responsive to changes in ambient temperature. The temperature compensation signal (108) is scaled, based on a plurality of discrete frequency adjust values (212), to produce the modified temperature compensation signal (110).

A portable data device (300) having a memory (302) is provided. The memory (302) is segmented into a plurality of sectors (304-312). A backup memory buffer (312) and a plurality of applications (304-310) are programmed into the plurality of sectors, wherein the backup memory buffer (312) is jointly used by the plurality of applications (304-310). A valid state of data is stored in the backup memory buffer (312) prior to performing a transaction for a first application (304). The valid state of data is restored in the first application (304) upon power up of the portable data device (300) in an event the transaction is terminated prior to completion, wherein the step of restoring is independent of a next application in which a next transaction is performed.

An apparatus for setting bearings that support a shaft in a housing in effect projects critical surfaces from within the housing out of the housing where the axial distance between them may be measured. Where the bearings are tapered roller bearings, a measuring element seats against tapered raceways and indeed has two tapers so that it may be utilized with bearings having differing tapers on their raceways.
