Title:
ROTOR UNIT AND BEARING PRELOAD PROVISION METHOD
Document Type and Number:
Japanese Patent JP2019078381
Kind Code:
A
Abstract:
To provide a rotor unit capable of providing appropriate preload to a pair of bearings rotatably supporting a rotational shaft.SOLUTION: A rotor unit comprises: a rotational shaft extending along an axial line; a pair of bearings rotatably supporting the rotational shaft; and a pair of spacers 80 of a roughly cylindrical shape arranged side by side in an axis direction between the pair of bearings, provided coaxially with the rotational shaft, and enclosing the rotational shaft. The pair of spacers 80 each have an inclination surface 82 inclined to a reference surface vertical to the axial line and contacting with each other. The inclination surfaces 82 are welded to each other, in a state where torque is imparted to the pair of spacers 80 in mutually opposite directions with the axial line as a center and thus a length from one end part in the axis direction of the pair of spacers 80 to the other end part in the axis direction is elongated.SELECTED DRAWING: Figure 12
