Model CBH
MODEL CBH COMBINATION CLUTCH-BRAKE
DESCRIPTION
The Model CBH combination clutch-brake is arranged so it
may be mounted in an end of shaft configuration. The unit is
a self-contained, oil cooled, hydraulically actuated
combination clutch-brake designed for maximum capacity
in a minimum space envelope.
The unit contains a spring-set, hydraulically released brake
while the clutch is hydraulically-set and spring released. The
clutch-brake action is effected using a shuttling piston
actuator which moves axially to engage either the clutch or
brake. With this arrangement, it is not possible to engage
the clutch and brake simultaneously so the possibility of
clutch or brake overlap does not exist.
The Model CBH unit uses only the best quality, time proven
materials within its construction and has been designed to
withstand the rigors of high cyclic applications with precision
machined clearances to provide the fastest possible
response.
The input flywheel, gear, or sheave is bolted to the clutch
driving member. The clutch-brake’s inner or driven members
can be keyed or splined to the machine’s output shaft for
maximum driving torque capacity and ease of assembly.
The stationary brake member is affixed to the machine
frame through the use of a brake mounting plate provided by
others.
The stationary housing provides a sealed cavity for the oil
that cools the clutch-brake disc packs. If external cooling is
required, this housing provides a means of oil entry and exit.
The cylinder/piston actuating mechanism has been
integrated within the brake hub thereby eliminating the need
for cross-drilling actuation oil entry holes in the user’s shaft
and the possibility of leakage at the hub/shaft interface.
The Model CBH combination clutch-brake is available with
high-cyclic rate actuation valve assemblies as well as
combination cooling/actuation hydraulic power units.
