For further practice with bolted assemblies, a three-body STEP assembly was created for a Sprocket Drive in NX-IDEAS 6.1 (2004 version). This model is a spinoff of the Bolted Dome Assembly posted earlier.
The slotted wheel section is a separate body, from the cylindrical section which is intended to be Joined to the wheel body. The sprocket and cylinder are adaptations of the dome and cylinder from the pressure box in earlier model, re-using bolt holes and pattern.
For my simulation, the five mounting holes of the wheel were Constrained. A force of (6000, 4000, 0 lb) was applied at the fillet of one tooth as shown.
The sprocket will be connected to the cylinder by 12 bolts. Your choice how to create.
- Manually create the flat spiders to washer faces (you create!), upward facing spiders near bottom of holes, and Bar elements connecting the spiders.
- Bolt Head creation, to automate creating the bolt head flat spider to washer face, and Bar element to the interface plane.
- Bolt Thread creation, to automate same for upward facing RBE2 and Bar element. I never succeeded getting this working, so they were easily created manually.
- Automated Bolt Head creation based on search of hole of size range, like the Altair demos, and same for Bolt Thread.
Let me know if anyone gets the Bolt Thread feature to work, and how-to-do. I tried hard, and always failed with nothing displayed after the pop-up it had succeeded, and nothing new in the browser. Darryl
