Solve the problem of powder metallurgy bearing vibration lead to precision

Vibration is sensitive to powder metallurgy bearing damage, such as peeling, indentation, rust, crack and wear will be reflected in the bearing vibration measurement, therefore, through the use of special bearing vibration tester ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation. Measured values of bearing or sensor installation position and different using conditions, thus requiring prior to each machine is analyzed by the measured value of the determined after judgment standard. Adjustment is according to the specific requirements of powder metallurgy bearing precision testing operation, while accuracy maintain and stable by 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 including hitches in bearing assembly process adjustment 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. Powder metallurgy bearing adjustment precision and test process and results, to be the unanimous approval stamps by 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.
