Abstract: In the embodiment shown, the assembly comprises a housing and a fluid-film journal bearing having pivoting elements arranged between the housing and the bearing to accommodate pivotal movement of the bearing within and spaced apart from the inner-housing surface. In addition, a damping plate is disposed between the bearing and the inner surface of the housing to prevent horizontal movement of the bearing within the housing and also to constrain vertical movement of the bearing. The pivot elements are engaged with flexure pads carried by the housing, the pads confining an elastomeric damper therewithin, and, in alternative embodiments, the flexure pads confine a visco-elastic substance, or oil, to control vibration.

Abstract: The arrangement comprises means for mounting a rotary type seal, especially a mechanical seal of the dry face type. According to an embodiment of the invention a seal mounting has a substantially circular recess in which a rotary dry face seal is received. Means (not shown) such as a key and keyway, or the like, causes a rotation of the seal mounting in common with a rotary shaft. The mounting disposes the rotary dry face seal for mechanical face sealing with a fixed seal member. The mounting recess has a circumferential inner surface which is out of round, and correspondingly the external periphery of the dry face seal is out of round, the two defining a slidable engagement therebetween. The eccentricity of the cooperating elements causes the seal mounting to engage and carry the sealing element therewith in rotation, in response to shaft rotation, obviating any need to dowel-pin the two elements together.

Abstract: The method involves forming an impeller with a slightly out-of-round hole in the center, and an impeller shaft with a complementary out-of-round peripheral surface, slidably engaging the impeller and shaft together, and then rotationally torquing either the impeller or shaft (relative to the other) to effect a binding lock-up of the two.
