A SJC-type
coupling has such characterisics as cannot be seen in
other couplings owing to its perculiar construction.
It means that the coupling has a complex feature that
combines characteristics of a backlash-zero metal
spring coupling and those of a coupling taking
advantage of a common rubber elastic body.
Accordingly, a SJC-type coupling is divided into 2
usages-one usage is the backlash-zero method adopted
in order to deliver the angle of rotation and another
usage is a method adopted in order to mainly deliver
torque. Because each usage has distinguished sleeves
of different hardness, please choose a proper
coupling. |

In case of using a coupling
within a low torque sphere with an aim to mainly
deliver the angle of rotation and effect control, the
same backlash-zero characteristic as a metal spring
coupling offers can be utilized. In addition, it also
has a function to absorb a torsonal vibration that a
common coupling cannot offer.
It becomes less than the torque listed in the table.
Please refer to the table in the below.
Although the allowable torque usable as a
backlash-zero torque is same with the 2 kinds of
sleeve, a sleeve, a sleeve of higher hardness can get
the excellent performance in a use of delivering the
angle of rotation correctly. |

A SJC-type coupling can be used
for higher torque than a metal coupling in that it
delivers torque by way of contracting the sleeve.
Accordingly, it can be applied to a geneal industrial
machine such as a pump in no need of backlash-zero.
Although the SJC-coupling are standardized in
different sleeves, green sleeves of lower hardness
offer less usual torque and maximum torque. While red
sleeves of higher hardness offer higher usual torque
and maximum torque. Thinking conversely, however,
allowable value of mis-alignment is bigger in the
green sleeves and less in the red sleeves. Please
choose a proper sleeve to fit your usage. |
