Jig for fixing bearing
First Claim
1. A jig for fixing a bearing with a tapered bore through a tapered adapter sleeve on a rotational shaft, comprising:
- a positioning member for attaching to a housing which receives the bearing, said positioning member having a positioning surface for positioning the bearing in the axial direction, the positioning surface contacting with an end of an inner ring of the bearing, the end of the inner ring being located on the small diameter side of the tapered bore; and
drawing means which engages with the tapered adapter sleeve and has driving means for moving said drawing means axially so that the tapered adapter sleeve is moved toward said positioning member for generating strong fixing forces between the tapered bore and the tapered adapter sleeve and between the tapered adapter sleeve and the shaft.

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.

11. A jig for fixing a bearing with a tapered bore through a tapered adapter sleeve on a rotational shaft, comprising:
-
positioning means for positioning the bearing in an axial direction, said positioning means being adapted for attaching to a housing which receives the bearing, and said positioning means including a positioning surface which contacts with an end of an inner ring of the bearing which is located toward the small diameter side of the tapered bore; drawing means for engaging with the tapered adapter sleeve, said drawing means inter-engaging with said positioning means; and driving means operatively connected to said drawing means for moving said drawing means along the axial direction such that the tapered adapter sleeve is drawn toward said positioning means and that strong fixing forces are generated between the tapered bore and the tapered adapter sleeve, and between the tapered adapter sleeve and the rotational shaft.
