Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
111 words
A bearing and housing assembly, comprising: a fluid-film bearing; a housing in envelopment of said bearing; means mounting said bearing, within said housing, pivotally on an axis perpendicular to said bearing; wherein said mounting means includes means accommodating relative movement between said bearing and said housing along said axis; and further including means interposed between said bearing and said housing, on opposite sides of said bearing, for damping said relative movement; and wherein said mounting means comprises flexure pads disposed transverse to said axis, on opposite sides of said bearing, and pivot elements interposed between said bearing and said pads in contacting engagement with only intermediate, axis-bisected portions of said pads.
Claim 2
Dependent Claim
111 words
A bearing and housing assembly, comprising: a fluid-film bearing; a housing in envelopment of said bearing; means mounting said bearing, within said housing, pivotally on an axis perpendicular to said bearing; wherein said mounting means includes means accommodating relative movement between said bearing and said housing along said axis; and further including means interposed between said bearing and said housing, on opposite sides of said bearing, for damping said relative movement; and wherein said mounting means comprises flexure pads disposed transverse to said axis, on opposite sides of said bearing, and pivot elements interposed between said bearing and said pads in contacting engagement with only intermediate, axis-bisected portions of said pads.
Claim 3
Dependent Claim
17 words
A bearing and housing assembly, according to claim 1, wherein: said damping means comprises rigid pressure plates.
Claim 4
Dependent Claim
37 words
A bearing and housing assembly, according to claim 2, wherein: said bearing has flat bearing surfaces formed on external, opposite sides thereof; and each of said flat bearing surfaces slidably engages one of said rigid pressure plates.
Claim 5
Dependent Claim
33 words
A bearing and housing assembly, according to claim 3, further including: adjustment means, carried by said housing, for causing said pressure plates to engage said flat bearing surfaces with a selectively variable pressure.
Claim 6
Dependent Claim
33 words
A bearing and housing assembly, according to claim 3, wherein: said pivot elements are partially nested in an outermost surface of said bearing and protrude therefrom, along said axis, to engage said pads.
Claim 7
Dependent Claim
21 words
A bearing and housing assembly, according to claim 1, wherein: said damping means includes means for selectively adjusting movement damping thereby.
Claim 8
Dependent Claim
36 words
A bearing and housing assembly, according to claim 1, wherein: said flexure pads and an inner surface of said housing together define voids therebetween; and further including elastomeric material disposed in said voids, for damping vibration.
Claim 9
Dependent Claim
40 words
A bearing and housing assembly, according to claim 1, wherein: said flexure pads and an inner surface of said housing together define voids therebetween; and further including means for introducing oil under pressure into at least one of said voids.
