Description

Apparatus for measuring the magnitude of a rotating body and a method for measuring the intensity using the same {RUN-OUT measuring apparatus for a rotation}

The present invention is to measure the displacement of the rotating body, such as a bearing for a wheel for supporting a wheel of the automobile, that is, the run-out measurement of the rotating body such as rotational vibration and vibration of the rotating body (french surface), and automatically The present invention also provides an apparatus for measuring the magnitude of a rotating body that can satisfy the rotational accuracy and the convenience of inspection at the same time.

In general, in the case of a rotating body, the rotating surface is accompanied with a displacement when the rotating force is generated. Therefore, knowing and managing this displacement value accurately prevents the degree of rotation of the rotating body and the vibration and vibration during the rotation.

For example, in the case of a vehicle using a disc, such as a wheel bearing for supporting a wheel of a car, such as a car, a brake is generated by restraining a pad mounted on a rotor of a disc brake. have.

As shown in FIG. 1, a double row of electric balls 300 are inserted between the inner member 100 and the outer member 200, and the inner wheel 100 or the outer member 200 has a wheel or the like. The flanges 120 and 220 attached to the vehicle body are integrally formed, and a plurality of hub bolts 150 are press-fitted into the flange 120, and the space into which the electric ball is inserted is sealed with seals 170 and 270 for airtightness. This prevents leakage of lubricating grease encapsulated inside and prevents ingress of rainwater or dust from the outside.

However, since the hub bolt 150 is fixed to the wheel attachment flange 120 of the rotating body by a forced press-fit method, it has become a major factor that hinders the flange surface runout and the brake rotor side runout accuracy.

Therefore, the brake judder phenomenon that causes vibration and low frequency unpleasant noise during low-speed driving of the vehicle is sometimes referred to as the shaking precision of the pad sliding contact surface of the rotor. The precision, the precision of the circumferential surface, such as the axial runout of rolling bearings, and the assembling precision of the rolling bearing, accumulate, resulting in impairing the surface runout accuracy of the brake rotor side.

In recent years, in pursuit of light weight for improved fuel efficiency, the above-mentioned brakes for wheel wheels have been eliminated in order to reduce the thickness of the wheels, and to meet the above-mentioned demands for improving the rigidity of the wheel bearings for steering stability. Measures for surface runout accuracy on the rotor side have been taken.
