Spinning or twisting shaft bearing assembly with vibration isolation connection arrangement

A spinning or twisting spindle bearing assembly for supporting a spinning or twisting spindle shaft, comprising:

• a spindle shaft neck bearing engageable with a spindle shaft at a first axial location thereof and serving to radially support the spindle shaft,
• a spindle shaft step bearing for radially and axially supporting an end portion of the spindle shaft at a location spaced axially of the first axial location,
• a spindle bearing housing enclosing the neck bearing and step bearing,
• an outer housing surrounding the spindle bearing housing with a radial spacing between the spindle bearing housing and outer housing forming an annular gap which extends from adjacent the location of the step bearing along a substantial portion of the axial length of the spindle bearing housing, said bearing housing being closed to prevent flow of lubricant fluid between the interior of the bearing housing to the annular gap,
• connecting structure for connecting the outer housing directly to a spinning machine frame member at an axial location of the spindle shaft which is axially spaced from the spindle shaft step bearing, wherein the annular gap between the outer housing and the spindle bearing housing extends from the connecting structure over substantially the entire remaining length of the outer housing,
• and a vibration isolation connection of the outer housing and bearing housing located axially spaced from the neck bearing and from the machine frame member, such that vibrations experienced in use at the neck bearing are transmitted indirectly to the machine frame member substantially only by way of the bearing housing to the vibration isolation connection and then through the outer housing to the machine frame member.
