Exploit The CAD Standard Parts Library Of Roller Bearings To PLIB Standard

Industry enterprise continually exploit the good quality, low cost, swift come into the market product by virtue of computer aided design(CAD) system. But because data format of different CAD system is different, it baffles the data exchange of the different CAD system. While two and more CAD system are integrated the large application with share data, there is a problem that the part information data can not communications. Different data format of CAD system baffle the part data exchange of standard part library and share of standard part in different CAD system, it baffles pass of manufacture information and reduce efficiency of manufacturing. If you want to settle the problem, the data exchange of different CAD system is the chief task. The data exchanges of CAD system have two way.The first way is direct correspond. The secondary way is indirect correspond. It does not need more processor by The neutral data library with standard PLIB. When we exchange the data by the neutral library.Text exploits the roll bearing's neutral file with standard PLIB, and found the neutral data library. I select the single, double row column roll bearing, single, double row taper roll bearing, move center ball roll bearing, move center roller roll bearing and especial holding frame.During establishing the tapered roller bearings model, there is difficulty that is caused from tapered roller being on a slight tilt to axis X and its location being not certainty in bearings. So I establish the new WCS. The bearings's axis is the new WCS's axis X and the O point is the point where the bearings's axis and roller's axis intersect. PLIB standard's rotate function is in accordance with the UG/OPEN GRIP's rotate function in the new WCS. The new WCS simplify the generation of model. We use function of PLIB standard for exploiting the neutral program of tapered roller bearings and perfecting the standard parts library.Text bearing part modeling way offer some referenced mind for after modeling. Besides ,it can achieve the data exchange from the neutral library with PLIB to UG system.
