Multi-channel rotary joint |
摘要 |
A multi-channel rotary joint including a first joint structural member rotatably linked to a second joint structural member. Sealing regions defined and formed by mechanical seals that are lined up concentrically around relative rotational axis are provided between opposing peripheral surfaces in a relative rotational axial direction of the first and second joint structural members. A plurality of channels passing independently through the sealing regions (except for the sealing region which is used as a drain region) are provided for the first and second joint structural members, and an electrical wire insertion path is provided so as to pass through the inner peripheral region of a mechanical seal that has the smallest diameter. A drain path that opens into the drain region is provided for the joint structural member. |
