•Use the skills you have learnt in other tutorials.
•Learn how to model a belt and chain with Piggyback-Sliders
•Introduce the Pattern FB.
•Learn how to use the Pattern FB to model chain links of an indexing chain.
This tutorial was prepared before the Motion-Path FB became available. We would now use the Motion-Path FB to prepare the path of the chain, and not Piggyback-Sliders. However, the Piggyback-Slider modeling technique is very useful.
1.Models the path of a point (Motion-Point) on a chain that moves at constant velocity - the belt is 1200mm long.
2.Models a chain-link on the chain - each chain-link is 100mm long, to give 12 chain-links.
3.Adds a Solid to represent the chain-link and the tooling attached to the link.
4.Makes copies the Solid with the Pattern FB.
5.Models the motion of the chain-link to an Indexing motion, with an index that is equal to the pitch of one chain-link pitch - 100mm.
