Designed with low inertia cycling
components makes the Posidyne®
clutch brake more efficient, requiring
less motor horsepower to accelerate
the load, and less torque to stop
the load. Their totally enclosed design
is impervious to dust, chips,
chemicals, coolants, caustic wash
down, weather, and more, making
them ideal for hostile environments.
Their multiple disc design produces
high torque from a small package.
Re-circulating the fluid dissipates
the heat of engagement, which
is a common cause of downtime with
other clutch/brake assemblies.
A simple actuation system allows
torque in the clutch and brake to be
precisely controlled. Adjustment for
rapid or soft starts and stops is easily
accomplished. Manifold mounted
control valves reduce response times
by eliminating hoses and fittings, and
are recommended for high cycle applications.
By reducing the high starting
inrush currents and the associated
power factor imbalance in the
motor, these unique clutch/brakes
can also reduce energy costs.
The Posidyne® clutch brake can
be actuated by air or hydraulic pressure
for use in a plant or outside remote
applications. The hydraulic
actuation package includes a hydraulic
pump, solenoid valve, regulators,
and a filter. A heat exchanger
can be added for additional cooling.
Oil Shear Technology is the reason
Originally the shear was designed to run even if the mechanism
is slightly out of position. This breakdown created a scrap
part and wasted material. (Image: Force Control Industries)
that clutch brakes by Force Control
last up to 10 times longer than standard
dry friction clutch brakes and do
not need maintenance, adjustment, or
disc replacement. Oil Shear
Technology is the function of a boundary
layer of transmission fluid in shear
between the friction discs and drive
plates. As the parts come together, the
fluid in shear will transmit torque between
the two parts, as well as absorb
heat. This eliminates direct contact of
the friction discs and drive plates
during high-speed slip. Heat from the
friction surface is dissipated as the
fluid circulates to the housing.
