Garter Springs, or Band Springs as they are sometimes known, are
a coiled length of
tension spring with some kind of end fixing
that enables you to join the ends together to make a continuous
ring. This enables the garter spring to function as a
compressive ring around shafts wheels or pulleys.
Garter springs are seen in a number of applications but the most
is in oil seals or as drive belts.
There are various different end forms that can be used in order
to make the ring connection. The simplest of course is to use a
hook and eye but this is not so secure. One other possibility is
to taper one end of the Garter Spring to enable you to screw it
into the other, sometimes known as a rat-tail end
design.
However the most secure and commonly used way is to use an
insert which is screwed into both ends to form the loop. This
insert is essentially a short close coiled length that fits
tightly within the inside diameter of the close coiled band
tension spring to ensure a tight and positive fixing.
