(1) Rotary joint
(a) Installation
Rotary joints are used to supply/exhaust high pressure fluid or liquid which is equal to or lower than the
atmospheric pressure from the fixed pipe to rotary parts of each mechanical device with no leakage. When
attaching a separate external-support type rotary joint to the shaft rear end, structure the rotary joint so that
cutting fluid (drain), which is generated when switching ON/OFF the coolant pressure, does not enter inside of
the motor.
(i)
Provide notches or drain so that the cutting fluid (drain) that has entered the rotary joint housing will not
accumulate.
(ii) A rotary joint is a consumable part. Check and replace regularly.
(iii) Many notches must be provided on the housing as a large amount of cutting fluid may leak if the rotary
joint is damaged.
(iv) If the motor is used vertically facing down, enhance the drain using parts such as an air purge.
(b) Recommended models of rotary joint
The tables below show the recommended models manufactured by Deublin and Rix. The target models are
designed to have these rotary joints attached to the shaft rear end. Contact the manufacturer for details of
rotary joint.
