Case StudyA bearing is defined by parameters such as its principal dimensions, its basic load ratings, its limiting speedsand its mass. It belongs to a category which corresponds a certain range of its parameter values. In acatalogue, a bearing is referred to by a designation. Bearing types are described by tables which define thebearing parameter values including the designation.The bearing example has been chosen here because the bearing tables given in distributor and retailercatalogues illustrate quite well the design table principles. The bearing itself is a good example of howcomponents within a mechanical part can be constrained by relations.The Data you Need to Perform the ScenarioThe required data is delivered with the <strong>Knowledge</strong> <strong>Advisor</strong> product.The starting documentThe bearing design tableAn import fileA CATScript macroKwrBallBearing0.CATPartKwrBallBearing.xlsKwrBallBearingImport.txtKwrMacro1.CATScriptWhen creating Rule4 in your own environment, you should replace the pathname given as the argument ofthe LaunchMacroFromFile function with the pathname corresponding to the file where the macro has beenunloaded.Some Explanations about your Starting DocumentThe document we start from in this case study is a part inspired by the SKF deep groove ball bearing withDesignation 623. Our purpose here is not to design an industrial ball bearing but to use a ball bearing as abasis to illustrate the CATIA knowledgeware capabilities.
Here are some details about the part design, the document initial parameters and its relations.The Document ParametersThe bearing rings are coaxial shafts created from the Sketch.1 and Sketch.2 features. The balls are shaftscreated from the Sketch.4 feature. To find out the role played by the various parameters, proceed as follows:1. In the specification tree, expand the PartBody feature and slide the cursor on the Sketch.1 feature Thesketch used to create the outer bearing ring is highlighted in the geometry area.2. To identify the sketch.1 parameters:1. double-click sketch.1 in the specification tree2. click the formula icon3. in the parameter list:select B.The B dimension is highlighted in the geometry area. Its value is set to 4mm. It definesthe total bearing width.
