Belt/Chain Assembly Feature
Belt/Chain Assembly Feature simulates a belt, chain, pulley or sprocket. It has the ability to include more than two components. This feature adds appropriate mates and relations to give you that desired rotational results. It will also create a sketch containing arcs and lines describing the path of the belt.
SOLIDWORKS will calculate the length of the belt depending on the positions of the pulleys, chain or sprocket.
The other cool part about this feature is, you have the option to automatically create a new part containing the belt sketch.
To create the Belt/Chain Assembly Feature follow these steps:
Click Assembly tab, expand Assembly Feature icon and select Belt/Chain.
In some cases, it may be helpful to switch to Hidden Lines Visible, located in your head-up toolbar.
Let’s create a belt using the two pulleys and the idler. The first selection will position the belt; however you have the option to reorder the selections using the arrow icons. You will need to select the edge from the selection box to reorder.
In this case, I want the belt in the v-grove of the pulleys, so I will have one of the pulleys as my first selection, Idler second and other pulley as the third.
You also have the option to Flip the belt from the inside or outside by selecting the edge and toggling on or off the Flip belt side icon. You can override the belt position by selecting a plane or a surface in the Belt Location Plane selection box.
The Properties area offers some belt definition choices. By making the belt Driving, we can set a specific or standard length of a belt.
There is also the Use belt thickness option. When this is selected, you can see the actual belt part. What’s important here, is the belt curve will be offset from all the pulleys by half the thickness. In this case I entered 15mm, the belt thickness will be 7.5mm.
Another option is Engage belt which allows the suppressing and in-suppressing mates. By unchecking this box the pulleys would move independently.
As I mentioned above, the really cool part about this feature is you have the option to automatically create a new part containing the belt sketch.
There you have it, another great feature to create motion in your assembly.
