Textile spindle mounting

Claim 2

A noise and vibration attenuating mounting for a textile spindle assembly comprising a rigid inner member including an elongate sleeve adapted for concentric attachment to the spindle assembly and a support ring carried by and extending radially from said sleeve, annular elastomeric means having portions secured to opposite radial faces of said support ring, a rigid washer secured along a first free radial face of said elastomeric means in parallel relation to said support ring and in radially spaced relation to said sleeve, a holder having a cylindrical casing portion concentrically surrounding said elastomeric means and support ring in radially spaced relation to said support ring and including radially outwardly directed mounting flanges, said holder including a radially inwardly directed annular clamping flange spaced from said sleeve and secured to a second free radial face of said elastomeric means opposite said first radial face, said washer at least partially extending axially beyond said mounting flanges of the holder, at least one annular axial surface of said elastomeric means being spaced radially from an adjacent axial surface of one of said elongate sleeve and said casing portion of the holder so as to permit radial shearing of the elastomeric means, the axial extent of the washer beyond the mounting flanges and the radial spacing of said elastomeric means being such that upon attachment of said mounting to a textile machine said elastomeric means is precompressed between the washer and the clamping flange and said axial surface of the elastomeric means remains spaced from said adjacent axial surface.

Claim 3

The mounting, as claimed in claim 1, wherein at each point along its length said elastomeric means is spaced radially about a circumference from at least one of said elongate sleeve and said casing portion of said holder and wherein a portion of said elastomeric means is radially spaced from both said elongate sleeve and said casing portion of said holder.

Claim 4

The mounting, as claimed in claim 1, wherein said mounting flanges comprise a pair of diametrically opposed flanges.

Claim 5

The mounting, as claimed in claim 1, wherein said elastomeric means is bonded to said inner member, washer and holder.

Claim 6

The mounting, as claimed in claim 1, wherein said elongate sleeve extends axially beyond said washer and mounting flange.

Claim 7

In combination, a textile spindle assembly, a textile machine spindle rail having an opening adapted to receive therethrough a downwardly extending portion of said spindle assembly and a noise and vibration attenuating mounting securing said spindle assembly to said rail, said mounting comprising a rigid inner member including an elongate sleeve concentrically secured about said downwardly extending portion of said spindle assembly and received through said rail opening in radially spaced relation to said rail and a support ring carried by and extending radially from said sleeve in axially spaced relation to said rail, annular elastomeric means having portions secured to opposite radial faces of said support ring, a rigid washer secured along a first free radial face of said elastomeric means adjacent said rail in parallel relation to said support ring and in radially spaced relation to said sleeve, a holder having a cylindrical casing portion concentrically surrounding said elastomeric means and support ring in radially spaced relation to said support ring and including radially outwardly directed mounting flanges, said holder including a radially inwardly directed annular clamping flange spaced from said sleeve and secured to a second free radial face of said elastomeric means opposite said first radial face, and means for securing said mounting flanges to said rail, the washer at least partially extending axially beyond the mounting flanges of the holder in the uncompressed condition of the elastomeric means, at least one annular axial surface of said elastomeric means being spaced radially from an adjacent axial surface of one of said elongate sleeve and said casing portion of the holder so as to permit radial shearing of the elastomeric means, the axial extent of the washer beyond the mounting flanges and the radial spacing of said axial surfaces being such that when the mounting flanges of the holder are secured to the rail said elastomeric means is precompressed between the washer and the clamping flange and said axial surface of the elastomeric means remains spaced from said adjacent axial surface.

Claim 8

In combination, a textile spindle assembly, a textile machine spindle rail having an opening adapted to receive therethrough a downwardly extending portion of said spindle assembly and a noise and vibration attenuating mounting securing said spindle assembly to said rail, said mounting comprising a rigid inner member including an elongate sleeve concentrically secured about said downwardly extending portion of said spindle assembly and received through said rail opening in radially spaced relation to said rail and a support ring carried by and extending radially from said sleeve in axially spaced relation to said rail, annular elastomeric means having portions secured to opposite radial faces of said support ring, a rigid washer secured along a first free radial face of said elastomeric means adjacent said rail in parallel relation to said support ring and in radially spaced relation to said sleeve, a holder having a cylindrical casing portion concentrically surrounding said elastomeric means and support ring in radially spaced relation to said support ring and including radially outwardly directed mounting flanges, said holder including a radially inwardly directed annular clamping flange spaced from said sleeve and secured to a second free radial face of said elastomeric means opposite said first radial face, and means for securing said mounting flanges to said rail, the washer at least partially extending axially beyond the mounting flanges of the holder in the uncompressed condition of the elastomeric means, at least one annular axial surface of said elastomeric means being spaced radially from an adjacent axial surface of one of said elongate sleeve and said casing portion of the holder so as to permit radial shearing of the elastomeric means, the axial extent of the washer beyond the mounting flanges and the radial spacing of said axial surfaces being such that when the mounting flanges of the holder are secured to the rail said elastomeric means is precompressed between the washer and the clamping flange and said axial surface of the elastomeric means remains spaced from said adjacent axial surface.

Claim 9

The invention, as claimed in claim 6, wherein said spindle assembly includes a mounting collar spaced from said rail on the side thereof opposite said mounting with opposite ends of said sleeve clamped between said collar and abuttment means carried by said spindle assembly.

Claim 10

The invention, as claimed in claim 6, wherein said means for securing said mounting flanges to the rail comprises an opening in each mounting flange, a threaded bore in said rail corresponding to each said flange opening, a bolt disposed through each said flange opening and threadably received in the corresponding rail bore, said flange openings being oversized relative to said bolts to permit adjustment of the spindle alignment during installation.

Claim 11

The invention, as claimed in claim 8, wherein said mounting flanges comprise a pair of diametrically opposed flanges.

Claim 12

The invention, as claimed in claim 6, wherein at each point along its length said elastomeric means is spaced radially about a circumference from at least one of the elongate sleeve and the casing portion of the holder, and wherein a portion of said elastomeric means is spaced radially from both the elongate sleeve and the casing portion of the holder.
