Definitions

  • the invention relates to a spindle rail for a spinning machine with a spindle unit arranged on the spindle rail, which has a spindle with a receiving section for detachable connection to a spinning tube and an electric motor with a rotor connected non-rotatably to a spindle shaft of the spindle.
  • the invention also relates to a spinning machine with a spindle rail.
  • Spinning machines of the type mentioned are known in a variety of configurations from the prior art. These have at least one spindle, each with a receiving section as a support for a spinning tube.
  • the spindle is preferably driven via a single drive, which is formed by an electric motor having a rotor and a stator.
  • the rotor which is non-rotatably connected to the spindle shaft, is coupled to an associated stator, which—like the spindle bearing—is arranged non-rotatably in a suitable bearing housing of the spindle unit.
  • spindle units In order to mount the spindle units on the spindle rail, it is necessary to position the individual spindle units in a stationary manner on the spindle rail via their housing, for which purpose appropriately designed fastening means must be used. In addition to the actual bearing housings, such spindle units have outer housings which surround the bearing housing. Overall, the known spinning machines therefore require a lot of space due to the space-intensive design of the spindle units, which results in spindle banks that take up a lot of space. The large number of components of known spindle units also results in high production costs.
  • the DE 41 06 953 A1 and the DE 39 42 914 A1 each disclose a spindle rail with a receiving opening in which a bearing guiding the spindle shaft and a stator of an electric motor are positioned without a separate housing.
  • the object of the invention is to simplify the exchangeability of the leading bearing.
  • the invention solves the problem by a spindle rail with the features of claim 1 and a spinning machine with a spindle rail with the features of claim 10.
  • Advantageous developments of the spindle rail are specified in the dependent claims.
  • the task is solved by a spindle rail for accommodating a spindle unit for a spinning machine.
  • the spindle unit has a spindle with a receiving section for detachable connection to a spinning tube and an electric motor with a rotor connected to a spindle shaft of the spindle in a rotationally fixed manner.
  • the spindle rail has a receiving opening.
  • the spindle unit does not have a housing that is separate from the spindle rail, but this is formed by the receiving opening of the spindle rail.
  • a bearing guiding the spindle shaft and a stator of the electric motor are positioned in the receiving opening.
  • the leading bearing is integrated in a flange unit with a passage for the spindle shaft to be supported.
  • the flange unit is interchangeably fitted into the receiving hole, and the leading bearing includes an upper bearing and a lower bearing which are arranged on a same side of the stator in the longitudinal axis direction of the spindle shaft.
  • the spindle rail has a receiving opening designed for positioning both the stator and the leading bearing.
  • positioning is understood to mean an at least non-rotatable connection of the leading bearing and of the stator.
  • a leading bearing is to be understood as meaning a bearing that is suitable for guiding and supporting the rotational movement of the spindle shaft about its longitudinal axis without tilting.
  • the leading bearing has a first upper bearing and a second lower bearing. The indication of the direction "up” or “down” is selected with a view to the receiving section for the detachable connection to the spinning tube.
  • a bearing close to the receiving section forms an upper bearing in the sense of the present invention.
  • the upper and lower bearings are on the same side of the stator, in particular with respect to one another immediately adjacent, arranged.
  • the upper and lower bearings can be arranged on a side of the stator facing away from the receiving section or on a side of the stator facing away from the receiving section. This allows a compact design of the leading bearing.
  • the leading bearing or the upper and/or lower bearing can preferably also be fixed in one or both axial directions of the spindle for the axial bearing of the spindle.
  • leading bearing is synonymous with the leading bearing itself and the upper and/or lower bearing of the preferred embodiment of the leading bearing.
  • the configuration according to the invention leads to a more compact construction of the spinning machine.
  • the spinning machine can be inexpensively manufactured since, compared to known spindle units, the costly components for forming a housing and the necessary fastening means for fastening the housing to the spindle rail can be dispensed with.
  • the individual drives can also be made more compact due to the omission of a housing that takes up space, so that the spindle unit on the spindle rail takes up only a small amount of space.
  • the spindle unit can be arranged in the housing-forming receiving opening by positioning the stator and the leading bearing as intended in any way.
  • the leading bearing is arranged on a bearing carrier which can be positioned in or on the receiving opening.
  • the bearing support is a flange unit which comprises the leading bearing or a component part of the leading bearing and can be inserted into the receiving opening in an exchangeable manner.
  • the flange unit has a passage for the spindle shaft to be stored. In the event of a defect or wear of the leading bearing or its component part comprised by the flange unit, this can be easily replaced with an exchangeable attachment.
  • interchangeable means non-destructive dismantling of the bearing support, in particular of the flange unit.
  • the flange unit preferably has a cylindrical shape in cross section with a front collar which is provided for resting on the spindle rail or abutting against the spindle rail, the cylindrical section being insertable into the receiving opening.

  • the bearing support can preferably be an element which traverses the receiving opening and which is arranged stationarily in the receiving opening in such a way that the bearing can be supported on the bearing support.
  • the attachment of the bearing carrier to the spindle rail can be selected as required from the conventional possibilities of form-fitting, non-positive and/or material-locking attachment.
  • a preferred backlash-free fastening within the receiving opening designed as an oversize or transition fit can be carried out, for example, by means of a press fit, which is particularly suitable for designing the bearing carrier as a crossing element and for fastening the stator within the receiving opening.
  • assembly can preferably take place in a manner known to those skilled in the art, for example by utilizing thermal effects when heating or cooling the corresponding components.
  • the bearing support in particular the flange unit, can preferably be designed in such a way that it can be fitted with a clearance fit so that it can be replaced.
  • the configuration of the spinning machine according to the invention makes it possible, in particular, to dispense with complex means for fastening the respective individual drives via their housing to the spindle rail.
  • the spinning machine according to the invention also offers the advantage that the spindle unit has a lower weight than known spindle units.
  • a positioning unit which fixes the stator and/or the leading bearing at a distance from one another in the direction of the longitudinal axis of the spindle shaft.
  • the positioning unit forms an assembly unit which, as an assembly aid, fixes the leading bearing or the stator to one another in the direction of the longitudinal axis of the spindle shaft.
  • the positioning unit does not offer any support for the leading bearing or the stator, but merely facilitates the assembly of the spindle unit in the receiving opening.
  • the positioning unit can, for example, be support rods that extend in the direction of the longitudinal axis of the spindle shaft and are connected on the outside to the leading bearing or to the are connected to leading bearing supporting bearing bracket or the stator.
  • the support rods can, for example, in order to ensure that the leading bearing or bearing carrier and/or the stator rests flat in the receiving opening, in correspondingly designed grooves in the receiving opening or in the leading bearing/bearing carrier and/or the stator, extending in the direction of the longitudinal axis of the spindle shaft get lost.
  • the use of positioning aids in the form of support rods for example three or four support rods arranged at equal intervals around the circumference, improves the axial position of the leading bearing and the stator relative to one another and facilitates assembly of the spindle unit in the receiving opening.
  • damping means are arranged in the region between the leading bearing and the receiving opening and/or between the stator and the receiving opening.
  • the damping means can be, for example, spring-elastic elements, elastomers, a fluid or a combination thereof, which support the leading bearing or the stator in relation to the receiving opening both in the radial and in the axial direction.
  • elastomers or fluids or a combination thereof are preferred for the damping because of the associated greater ability to convert energy and thus damping than the spring-elastic elements.
  • the damping means serve to dampen the precision movements of the spindle.
  • the damping means are particularly preferably ring-shaped and have a permanent restoring behavior, so that the spindle center and the vertical spindle position do not change over time.
  • the positioning unit provided has a damping means or is designed as a combined positioning and damping unit.
  • the configuration of the positioning unit with damping means makes it possible to dispense with an arrangement of separate damping means.
  • the design of the positioning unit with the properties of a damping unit makes it possible to dispense with additional components, with the combined positioning and damping unit offering both the possibility of aligning the leading bearing and the stator in the axial direction of the spindle shaft and in relation to the receiving opening elastically to support.
  • the spindle can be supported in the axial direction in any desired manner.
  • the leading bearing for absorbing the forces acting axially on the spindle can be designed as a fixed bearing.
  • the leading bearing rests against a support surface that at least partially overlaps the receiving opening in the direction of the longitudinal axis of the spindle shank.
  • the support surface can be, for example, a cover that closes the receiving opening and through which the spindle shank protrudes or which encloses the spindle shank in a preferred embodiment.
  • the support surface can be formed in a particularly preferred manner by the bearing bracket. Alternatively or additionally, the support surface can be arranged in or on the receiving opening.
  • the support surface can preferably be formed in one piece with the spindle rail, molded onto or attached to the spindle rail.

  • An external arrangement of a connection point can also be provided on the spindle rail in a preferred manner, as required, in such a way that corresponding current collectors can be supplied with electricity in a simple manner.
  • An external arrangement means all accessible side walls of the spindle rail that physically delimit the spindle rail. For example, the side walls of the spindle rail that are accessible within a receiving opening also form an outside for the arrangement of such a connection point.
  • the receiving opening is cup-shaped.
  • the receiving opening in a cross-sectional plane which runs parallel to the direction of insertion of the spindle unit, the receiving opening has a U-shaped or similar, for example V-shaped, cross-sectional shape.
