The invention provides a bearing assembly assemblability identification method based on a three-dimensional model. The method comprises the following steps: establishing a bearing detail configurationdatabase; determining an assemblability judgment standard of the effective length of the matching surface; determining a bearing inner matching part, a bearing inner matching surface, a bearing outermatching part and a bearing outer matching surface which are matched with the bearing assembly; obtaining the effective length L3 of the bearing inner matching surface and the effective length L4 ofthe bearing outer matching surface; and judging whether the bearing inner and outer matching parts meet the assemblability requirement or not. The method has the advantages that (1) the effective length of the inner and outer matching surfaces of each bearing in the three-dimensional assembly model is automatically obtained; the ratio of the thickness of the bearing inner ring to the thickness ofthe bearing outer ring to the thickness of the bearing inner ring is calculated, the result of whether the assemblability requirement is met or not is given, and compared with a previous manual inspection mode, inspection of the assemblability of the bearing inner matching part and the bearing outer matching part is more comprehensive, higher in accuracy and higher in speed; and (2) the application range is wide.
Description
technical field [0001] The invention belongs to the technical field of bearing component assemblability identification, and in particular relates to a method for identifying the assemblability of a bearing component based on a three-dimensional model. Background technique [0002] Bearing assembly is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. In order to ensure the function of the bearing assembly, the bearing assembly in the mechanical equipment and its matching internal and external bearing parts are often connected by interference fit, which makes the installation and disassembly of the bearing assembly difficult. In three-dimensional product design, if the effective length of the mating surface between the bearing assembly and the inner and outer fittings of the bearing is too long, the bearing assembly may not ...
