Coupling Device Selection and Handling
Item Description Remarks
(1) Coupling device
selection precautions
① Selection of the coupling device should be based on the
following factors:
② If the selected coupling device is larger than necessary
(when used in high vibration/shock environments), the load
which is applied to the shaft by the vibrations/shocks will be
increased by the weight of the coupling device.
③ Be sure to select a coupling device with an adequate
transmission torque surplus relative to the Sensor shaft’s
torque.
A larger than
necessary coupling
device will increase
the ‘mounting error’
shaft load
accordingly.
(2) Coupling device
installation precautions
① Never hammer the coupling device into position, and be sure
that it is mounted in a straight manner.
Excessive force may
deform the coupling
device, thereby
reducing is efficiency
and durability.
