CHAPTER 11Mechanism Assembly
11.1 Introduction
The purpose of an assembly is to establish relationships between parts and to see how various constraints impact their relationship. Because the final product may also be a moving assembly, we can introduce joint connections between the moving parts to observe how the product may behave. You can consider the mechanism assembly and animations as a simulation that provides motion analysis for proper assembly designs and catch problems early on. In Creo mechanism assembly application, there are four basic joint connections: 1‐Pin, 2‐Slider, 3‐Cylinder, and 4‐Planar.
Pin joint connection is applied on an axis to provide rotational motion along the axis it is aligned to. Slider connection needs pin connection for an axis, then align or mate a flat surface to the assembly. The slider provides a translational motion on the aligned surface. Cylinder connection allows both rotational and translational motion on the axis aligned to the assembly. Planar connection provides a perpendicular rotational motion to the aligned surface and additional two translational motions (Figure 11.1).
