Technical Field
The invention relates to the technical field of bearings, in particular to a bearing grinding machine spindle with fine adjustment and single-point finishing.
Background
The bearing is an important part in the present generation mechanical equipment, its main function is to support the mechanical rotating body, reduce the friction coefficient in its motion process and ensure its rotation precision, according to the difference of friction properties of moving elements, the bearing can be divided into two categories of rolling bearing and sliding bearing, in which the rolling bearing is standardized and serialized, but its radial size, vibration and noise are larger and its price is higher than that of sliding bearing, the rolling bearing is generally composed of four portions of outer ring, inner ring, rolling body and retainer, according to the shape of rolling body, the rolling bearing is divided into two categories of ball bearing and roller bearing, when other parts produce relative motion on the shaft, the rolling bearing is a part which is a kind of heavy component in the present generation mechanical equipment and is used for reducing the friction coefficient in the power transmission process and keeping the central position of the shaft fixed, in the mechanical product, the bearing belongs to a high-precision product, not only needs comprehensive support of various subject theories such as mathematics, physics and the like, but also needs various subjects such as material science, heat treatment technology, precision machining and measuring technology, numerical control technology, effective numerical method, powerful computer technology and the like to serve, so that the bearing is a product representing the national technological strength.
The single-point grinding wheel finishing main shaft is a grinding shaft for processing a grinding wheel, but the conventional single-point grinding wheel finishing main shaft has the defects of unreasonable internal design, low rotation precision, large vibration and unstable transmission, so that the roughness of a ground product is large, and the service life of a bearing is influenced.
