(c) Installation of coolant joint
Install the coolant joint to the motor shaft end so that it stops at the shaft edge. Stopping the coolant joint at the
edge of the inner diameter or at the screw bottom may generate an excessive radial runout, which may
generate abnormal noise or vibration.
(3) Coupling
(a) Caution when selecting coupling
Always use a flexible coupling for coupling the spindle and the motor. The flexible coupling is flexible enough
to absorb a certain level of radial runout and parallel offset. The flexible coupling has tolerable values for three
degrees of freedom (parallel offset, angular misalignment, and axial movement), which realizes a low-vibration
and low-noise coupling up to high-speed rotation.
- Tolerable values of parallel offset and angular misalignment:
Absorbs minor misalignments or declinations that were not resolved during alignment.
- Tolerable value of axial movement:
Absorbs elongation of the spindle and motor shaft due to thermal expansion.
(These tolerable values are the standard values for which the coupling does not break. They are not the
standard values for which the load is not applied to the spindle or the motor bearing. Thus, in order to
rotate up to high-speed with low-vibration and low-noise, the spindle and the motor shaft must be
aligned.)
(b) Recommended model of coupling
The table below shows the recommended models manufactured by Miki Pulley and Eagle Industry.
(Note)
The diaphragm coupling in the table above absorbs the misalignment of the rotary axis with the
elastic deformation of the extremely thin metal diaphragm. In addition, there are the features as light
weight, no lubrication and high torsional stiffness, so it is recommended as a coupling of a high-
speed motor.
