Abstract

An assembly, or device, for measuring the end play in the bearing of a turbine hub of a torque converter in which the turbine hub is provided with a bore therethrough and the turbine is enclosed within a casing, the casing being provided with a single opening in one side thereof having a hollow hub extending outwardly from and about said casing opening, the axis of the opening in the casing hub being in alignment with the bore in the turbine hub, the measuring assembly or device being provided with a base portion having a flat upper surface, and an under surface parallel with the upper surface, the base being provided with an aperture whose side wall extends upwardly from the upper surface of the base, a spindle slideable through the aperture in the base and of such length as to extend through the hollow hub of the casing and in engagement with the bore in the turbine hub for moving the turbine in the measuring operation, the means engaging the turbine bore being of cone shape and extending outwardly from the spindle, the smaller end of the cone adapted to extend into the bore and the larger end of the cone adapted to engage the outer peripheral edge of the bore, the spindle further being provided with means for measuring the movement of the spindle after the upper end of the spindle is in contact with the bore of the turbine hub, means being provided for releasably fixing a measuring gauge to the spindle below the under surface of the base and means connected with the gauge for engaging the under surface of the base for operating the gauge when the spindle is moved relative to the base.

Dependent claims

In a transmission torque converter comprising a casing having an opening therein, a bearing supporting a turbine having a central bore therethrough carried within said casing, and a hollow hub fixed about said casing opening of a larger diameter than the turbine bore and having at least its outer surface perpendicular and on the same axis as said turbine bore, an assembly for measuring the end play of said bearing, said assembly comprising:

a. a base having parallel upper and lower surfaces, each of said surfaces being in a single parallel plane, the upper surface of the base being adapted to receive the outer end of the casing supporting hub, means for supporting the base in a substantially horizontal plane, said base having an aperture extending therethrough, the walls of the aperture being substantially perpendicular to at least the upper surface of the base;
b. a spindle of smaller diameter than the diameter of the hollow hub and adapted to slide through said aperture in the base;
c. the upper end of the spindle being cone-shaped and tapered inwardly toward its outer upper end adapted to engage one end of the said turbine bore;
d. a gauge-supporting bracket having an aperture therethrough adapted to normally slide along said spindle and positionable on said spindle below the base, said bracket having means for releasably fixing the bracket to the spindle at selected locations;
e. a measuring gauge fixedly supported upon said gauge-supporting bracket having operatable means adapted to engage the underside of the said base for operating the same for measuring the movement of the spindle through the aperture in the base,
whereby the end play in the turbine bearing may be recorded on the gauge upon the upward movement of the spindle after its upper end has been placed in contact with the hub bore of the turbine.
