INA bearing the precision of the detection and adjustment - bearing knowledge

Hydraulic press because of its form a large size, heavy weight, by casting, forging, machining, assembly, and the limitation of various technological conditions, the work precision of press itself is unlikely to be completely rely on mechanical processing itself to guarantee, and must pass the assembly in the process of adjustment to meet the precision index. Adjustment is operated according to the concrete requirements of INA bearings detection accuracy, and precision of the keep and solid, want to rely on the related preloaded 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 INA 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. INA 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.
