Check the accuracy of IKO bearing and load

Adjustment is operated according to the concrete requirements of IKO bearing detection accuracy, and precision of the remains and firm depends on the related pre-tightening and locking means and measures to guarantee. Hydraulic press used by all walks of life, because of its USES different is different on the working accuracy requirements, also used in the manufacture of different industry standards. In the same industry due to the production of different products, the requirements of the precision is not likely to agree. So in the same industry standard according to different working conditions is divided into several levels and the corresponding precision index. Factory production by the technical department according to the production of the precision of the press in the standard test syllabus and test outline, issued by the relevant departments as a guidance document, which regulates related project and parameter of the detection method and the corresponding data, as the standard to install and check acceptance. Generally include need to adjust hitches in IKO bearing assembly process to achieve the accuracy of the project. As in hydraulic press for the levelness of the workbench, column spacing deviation, workbench and activities of table flatness, column connected to upper beam of perpendicularity, parallelism between the workbench, the main oil cylinder within the work schedule and verticality of the workbench, columns and fluctuation beam connections on the surface of the inner and outer nut joint exposure rate, etc. IKO bearing adjustment precision and test process and results, to Fang Ketong signatures and seal of approval full-time staff. Tools needed in the process of adjustment and tooling design by counterpart professional technology personnel in production after into the production process as planned. Inspection and testing and adjusting operation outline of omitted. Preloading method: in the early period of the load positioning is a bearing shaft relative position, in use will not change the preload method. Here an example: 1, all kinds of crack, crack, such as raw materials, forging crack, crack and grinding cracks, heat treatment, the crack in the process of bearing after operation, will become a source of stress concentration and expanded rapidly, cause bearing fracture, great influence on bearing life and job security. In fact, for important use of bearings, bearing factory has been to 100% of their component parts magnetic or radiographic inspection. 2, all kinds of machinery, such as abrasion, cut and bruised, crushed, can cause adverse bearing installation, causing partial load and stress concentration, caused by rotation precision and service life. 3, peeling and folding, the two defects of local combined with matrix metal not firm, and its surroundings often exist in different degrees decarburization or poor phenomenon, carbon material easy caving, the indented or wear, bearing life and accuracy very unfavorable. 4, rust, black and pitting, the latter two are easy to store water and dirt of defects, most likely to develop into rust. The corrosion is caused pollution sources, the installation of non-performing, early wear and fatigue serious corrosion will make the bearing damaged. 5, maintains a riveting or welding quality, mainly to see whether it has offset the rivet head, skew, relaxation, lack of meat, or 'double eyelid, correct the position of the welding, solder joint is too big or too small, for welding not firm or excessive cause jam phenomenon of roller. More than a few we check key check part of IKO bearings, in addition to the above tests.
