OPERATION
The
wrapped spring hinge is comprised of a housing, inner drum
(hub), and a stepped spring. The larger diameter step, nests
inside the housing while the smaller diameter spring step
fits tightly over the inner drum. The housing and inner
drum are therefore effectively coupled together by the spring.
When the inner drum is rotated in one direction, the small
diameter spring step rotates together with it, while the
large diameter spring step slips inside the housing. When
the drum Direction is reversed the large spring diameter
step locks inside the housing and the small spring diameter
step slips over the inner drum. The slip torque is the rated
torque of the hinge and represents the maximum unbalanced
load torque the hinge will support. The spring-wrapped,
friction braked hinge is ideally suited in applications
requiring the maintenance of an unbalanced torque load in
any desired position, through 360º, about a given rotary
axis. |
INSTALLATION
The
model FH-1 friction braked hinge body has built in anti-rotation
flats and grooves which allow for both rib and nest installation.
In typical rib installation the support material is slotted
to the proper dimension across the hinge grooves. The hinge
is in then simply slipped into the anti-rotation slot. In
a nested installation the flats across the hinge body provide
the anti-rotation feature. In this case flats are molded
in the support material to correspond to the dimensions
of the flats on the hinge body.
Figure-1 illustrates
a typical rib installation. The sheet metal chassis(stationary
member) provides the longitudinal support for each end.
A flatted shaft fitted to the hinge bore and the proper
length for the installation is held in place by retaining
rings. The cover or platform is keyed to the flatted shaft.
The cover may be rotated to any position bi-directional
through 360º position. The cover will stay in position at
any angle. |
