Description

Technical Field

[0001] The present application relates to the technical field of bearing ring detection, and in particular to an eddy current detection machine for a bearing ring. Background Art

[0002] Bearings are a type of mechanical component, mainly used to reduce friction and support the rotation of mechanical bodies; bearings are usually composed of rings, rolling elements (such as balls or rollers) and cages. The rings usually include inner and outer rings. The inner ring is usually installed on the shaft, and the outer ring is installed in the bearing seat or machine parts. The rolling elements roll between the inner and outer rings to reduce the friction between the inner and outer rings. The cage is used to evenly separate the rolling elements to prevent adjacent rolling elements from colliding with each other, ensuring the smooth operation of the bearing.

[0003] Usually, bearings need to go through a testing process before leaving the factory, so that they can be directly used in various mechanical equipment. Typically, wheel hub bearing rings need to be tested for cracks in all aspects before leaving the factory, and crack testing usually uses eddy current flaw detection for conductive materials. This detection method can detect the rings non-destructively without contacting the rings.

[0004] Reference Figure 1 Generally, wheel hub bearing rings of any size include at least four surfaces. Typically, the inner ring of a wheel hub bearing includes two end surfaces a, an inclined circumferential surface b and a vertical circumferential surface c. During inspection, the above four surfaces need to be fully inspected to meet the requirements of comprehensive crack detection.

[0005] When the existing bearing ring inspection machine inspects the four surfaces of the above-mentioned ring, workers are required to assist in loading and unloading materials and adjusting the position of the ring.
