Patent ID: 6993852

Claim:
A gauge for setting a pair of tapered roller bearings mounted in opposition along a common axis and between inner and outer machine components, one of which has a cylindrical surface to which a race of one of the bearings is to be fitted with an interference fit and also has a reference surface located at an angle with respect to the axis, said gauge comprising: a base having an end face configured to fit against the reference surface and at its other end configured to hold the race that is to be fitted to the cylindrical surface, so that the race is detached from said one machine component; a first gauge element mounted on and shiftable axially relative to the base and having a gauging surface for contacting a conical envelope on the detached race that is carried by the base; a second gauge element also mounted on and shiftable relative to the base and having a gauging surface for contacting an identical conical envelope on the bearing of which the detached race is also a part; a first measuring device for determining the axial positions of the first and second gauge elements to ascertain the distance between gauging surfaces on them; a second measuring device for determining the diameter of the race that is carried by the first gauge element; and a third measuring device for determining the diameter of the cylindrical surface of the one machine component, so that the magnitude of the interference fit may be ascertained.
