Ball bearing disc springs slotted and plain
This two types of disc spring are designed to be set up
allong with the ball bearings to act as an elastic support
which allows it to absorb vibrations and to compensate thermal
dilatations produced by the heating/cooling of the axis where the
ball bearing is set up. Which results on a longer life and on a
reduction of the noise produced.
Plain
This ball bearing disc spring results in the following
graph:
The spring has a high stroke and a low force, which can
successfully protect a ball bearing.
Slotted
This discs are an improvement over the plain disc. The
slots contribute in making a much more interesting Force-Stroke
diagram. As you can see the spring reaches a point where with a
constant force, there is a stroke. Due to its properties this
spring protects the ball bearing preventing consecuences from a
thermal dilatation.
Slotted discs are less rigid and taller. It must also be
mentioned that slotted disc springs can be stacked in
parallel to obtain a given desired force.
Materials
Ball bearing disc springs are manufactured from high quality spring
steel; they can also be made to order in other materials e.g.
corrosion resistant or non-magnetic steel, spring bronze Cu Sn 8,
copper beryllium alloy Cu Be 2, Nimonic 90 and others.
