Abstract
The jig includes an upper jig part, a lower jig part, a support plate, a guide jig part, and a spring. The upper jig part has a pressure protrusion for press-fitting a rotating shaft, and applies pressing force to the rotating shaft. The lower jig part supports a rotor casing in a direction which is opposite the acting direction of the pressing force. The support plate is mounted to the lower jig part, and supports the rotor casing in a direction which is opposite that of the force for press-fitting the rotating shaft. The guide jig part supports the rotor casing in a direction which is opposite that of reaction force generated in the rotor casing by the support plate. The spring elastically biases the guide jig part towards the rotor casing.
Claims4
A jig for assembling a rotor including a lower jig locating a rotor casing in its upper part and an upper jig to pressurize the rotating shaft to press-fit the rotating shaft to the rotor casing, comprising:
- a support plate located at the upper part of the lower jig opposite to the rotor casing to support the rotor casing in a direction opposite a direction in which force pressing the rotating shaft acts;
- and
- a guide jig pressurized by the upper jig to support a rotor casing in a direction opposite an acting direction of reaction force which is generated in the rotor casing by the support plate,
- wherein the support plate is made of the same material as a rubber ring mounted to the rotor casing to prevent the slippage of a recording medium, and has the same thickness as the rubber ring, the support plate supporting a surface of the rotor casing having no rubber ring.
