Adjusting method for restraining inclination angle rotation errors of two-end supporting shafting structure

Abstract

The invention relates to an adjusting method for restraining inclination angle rotation errors of a two-end supporting shafting structure, and belongs to the technical field of precision shafting structure adjustment. According to the adjusting method, firstly, a model of the two-end supporting shafting structure is established, the adjusting method for restraining the inclination angle rotation errors of the two-end supporting shafting structure is introduced through the model, the steps are clear, dependence on the adjustment experience of operators is reduced, the method has the characteristic of completeness, assembling and machining errors can be effectively restrained by adopting the method to perform adjustment, and then the inclination angle rotation errors of the two-end supporting shafting system structure are effectively restrained.

Description

technical field [0001] The invention belongs to the technical field of assembly and adjustment of precision shafting structures, and in particular relates to an assembly and adjustment method for suppressing inclination rotation errors of shafting structures supported at both ends. Background technique [0002] At present, the assembly and adjustment of precision shafting structures is a core technology mastered by only a few units in China. It is an industry secret, and most of them are mastered by experienced technical experts. The quality of the assembly and adjustment is highly related to the experience value. . No patent has been retrieved for announcing an assembly method for suppressing the inclination rotation error of the supporting shafting structure at both ends. Check the patents related to the inclination rotation error, and find that most of them are related to the test method. For example, the patent CN 106352846 A provides a test method for the inclination r...

Patent CN 106624776 A discloses a shafting assembly method supported by a bidirectional single bearing with a certain span. This method improves the rotation accuracy of the shafting system by reasonably adjusting the preload of the bearing, and can adjust the rotation accuracy to 10″ However, if the coaxial accuracy of the bearing holes at both ends of the frame with a certain span is not enough, it will be difficult to further improve the rotation accuracy by this method

Patent CN 105387829 A discloses a method for adjusting the concentricity of the left and right half shafts of the turntable. The test index for installation and adjustment does not involve the inclination angle rotation error of the shaft system. The installation and adjustment method is to assemble the bearing on the right half shaft, fix the bearing seat, and measure the The shaft diameter jumps, and then adjust the left semi-axis to the allowable range. This method of adjustment is not perfect for the shaft system with high requirements on the inclination angle rotation error.
