Abstract
A unitary, fully-assembled bearingless coolant union which transfers cooling fluid from a fluid source to an axial bore of a rotating spindle on a stationary machine. The union includes a main housing which holds in position both a rotor assembly and a stator assembly such that a rotating seal on the rotor assembly remains in fluid-tight contacting relation with a non-rotating seal on the stator assembly. Means are provided to allow the seal members to move axially with respect to the spindle's axis of rotation in response to axial movement by the spindle itself and to allow the inclination of the seal members from a plane transverse to this axis of rotation in response to minor misalignment of the rotor assembly from concentric relation with this axis of rotation. The two-step process for installing the union includes (1) attaching the end of the rotor assembly to a spindle, and (2) mounting the union's housing assembly upon the stationary machine within the allowable set-up tolerance.
