Two
basic types of couplings are being offered, Type ES Rubber Elastic Coupling,
and Type CC Roller Chain Coupling. Both combine the full overload protection
capabilities of the CG Crossgard with facility of shaft to shaft connection.
Type
CG-CC Couplings
A standard roller chain sprocket is connected by a duplex roller chain to a
platewheel mounted on the CG Clutch. This construction provides a simple,
reliable, low cost means of transmitting drive with minimum backlash, and
accommodating reasonable shaft misalignment. Both Taper-bored and pilot bore
sprockets are available.
The ES Couplings consist of two close grained cast
iron jaws with hard rubber drive elements interposed.
It is a low inertia coupling combining quiet operation
with torsional elasticity to absorb shock loads and damp
vibration.
These couplings can be supplied with pilot bore, finish bore and
keyseat and setscrews, or fitted with clamping elements to clamp
directly to keyless shafts. The use of clamping elements eliminates
all backlash in the drive line within the operating torque range, but
does require an increase to the overall length of coupling in order to
accommodate. Coupling and clamping element assembly are supplied to suit
specific metric shaft sizes. Clutch and Coupling half can have different
bush sizes. Each model can have three different torque ranges which is
achieved by using different types of spring.
For shaft to shaft connection the CGZ Couplings provides total
disengagement in the event of overload. Suitable for mounting on
high speed shafts. The coupling consists of two close grain cast
iron jaws with hard rubber drive elements interposed. A low inertia
coupling which combines quiet operation with torsional elasticity
to absorb shock loads and damp vibrations.
