This article is part of a section of the RcTek site that is devoted to informing the radio controlled model car racer about the various fixings & fasteners that are used in remote controlled model cars.
In this article we have information for the model racer about Belleville Washers.
Belleville washers are simple in their operation and provide an inexpensive and compact springing solution.
If you Play the animation to the right, which shows a cross-sectional view of belleville washer, you will see how a load applied to the centre is distributed to the edges of the washer. As it is a spring, when the load is removed, it returns to its former state.
Obviously the reverse is true in that a compressing force can also be applied to the edges to transfer the force to the centre.
Their Limitations
As they are such a compact springing solution, there isn't a great deal of movement available with each spring.
This limitation can be overcome by placing multiple springs next to each other. These must always be placed back to back as shown in the image on the left.
Those who needed a progressive springing solution could always use springs of different thickness (made from thinner gauge steel).
Summary
This article serves primarily as a reference to other articles on this site, but if it helps you, have a nice day!
