Abstract

A noise and vibration attenuating mounting for a textile spindle assembly includes a rigid inner member having an elongate sleeve adapted for attachment to the spindle assembly and a support ring carried by and extending radially from the sleeve. An elastomeric annulus includes portions secured to opposite radial faces of the support ring, preferably in radially spaced relation to the sleeve. A rigid washer is secured along a first free radial face of the annulus in radially spaced relation to the sleeve. A cylindrical casing portion of a holder concentrically surrounds the annulus and support ring in radially spaced relation to the support ring. The holder includes a radially inwardly extending clamping flange secured to the other free radial face of the annulus in radially spaced relation to the sleeve. At least a portion of the washer extends axially beyond the holder. Mounting flanges are provided for attachment of the casing portion of the holder to the spindle rail of a textile machine and allow for precompression of the elastomeric annulus between the washer and clamping flange upon installation to the spindle rail.

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.

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.
