Background

The bearing is an important part in the modern mechanical equipment, and the main function of the bearing is to support a mechanical rotating body, reduce the friction coefficient in the movement process and ensure the rotation precision of the mechanical rotating body. The bearing bush is a part of the sliding bearing contacted with the rotating shaft, is in a bush-shaped semi-cylindrical surface, is very smooth, is generally made of wear-resistant materials such as bronze, antifriction alloy and the like, the thickness dimension of the bearing bush is determined by the radius difference between the inner cylindrical surface and the outer cylindrical surface of the bearing bush at the positions of the central symmetry plane and the upper bottom surface and the lower bottom surface of the bearing bush, and the requirement on the precision of the thickness dimension of the bearing bush is very. When the sliding bearing works, a layer of thin oil film is required between the bearing bush and the rotating shaft to play a role in lubrication, a layer of oil film molecules is arranged between the inner surface of the bearing bush and the shaft, the gap is small, and the oil film plays a role in lubrication, so that the requirement on the thickness of the bearing bush is high and is in a 0.001 millimeter level. If the load is too large, the lubrication is poor or the quality of the bearing bush is not good, direct friction exists between the bearing bush and the rotating shaft, high temperature can be generated due to friction, although the bearing bush is made of special high-temperature-resistant alloy materials, the high temperature generated due to direct friction is still enough to burn the bearing bush, and therefore the processing and manufacturing and wall thickness detection of the bearing bush are very important. The conventional bearing bush (half bush) wall thickness measurement usually adopts a general or special measuring tool and depends on manual inspection, and due to the influence of the precision and human factors of the measuring tool, the measuring tool has low measuring precision, high labor intensity and easy scratch on the surface of a product.
