Abstract
According to the present invention, a jig for fixing a bearing with a tapered bore through a tapered adapter sleeve on a rotational shaft comprises a positioning member which is attached to a housing receiving the bearing and which has a positioning surface for positioning the bearing in the axial direction, and drawing means which engages with the tapered adapter sleeve and which have driving means for moving the drawing means axially so that the tapered adapter sleeve is moved toward the positioning member. Movement of the tapered adapter sleeve generates strong fixing forces between the tapered bore and the tapered adapter sleeve and between the tapered adapter sleeve and the shaft. The positioning surface contacts with an end of inner ring of the bearing, which is located on the small diameter side of tapered bore.
