Definitions

  • the invention relates to a device for mounting a spinning, twisting or winding spindle with a foot bearing arranged in a common bearing housing and a neck bearing for the spindle.
  • Such bearings in which the neck and foot bearings are generally elastically mounted together, are already known in a wide variety of designs.
  • This double elastic bearing for the spindle enables extremely high spindle speeds and is therefore particularly suitable for use in high-speed ring spinning machines. Due to the separate elastic mounting of the foot and neck bearings, the bearing forces that occur are kept to a minimum, resulting in an extremely quiet and low-noise spindle.
  • the invention has for its object to provide an additional elastic mounting for spindles, in which the neck and foot bearing for the spindle can be arranged in any way spring-loaded in a bearing housing.
  • the object is achieved with a device of the type mentioned at the outset in that it has an outer housing in which the foot region of the bearing housing is articulated and an upper region of the bearing housing is spring-mounted in the radial direction.
  • the internal structure of the spindle bearing within the bearing housing is completely arbitrary in the device according to the invention. All conventional spindle bearings can be used for this.
  • the desired additional elastic mounting is created by the hinge at the foot area of the bearing housing, which forms a fulcrum for pivoting movements of the bearing housing within the outer housing, the deflections of the bearing housing being radially cushioned in the upper area.
  • the joint between the foot region of the bearing housing and the outer housing can be designed as a spherical shell, spherical plate or tip joint.
  • the joint is characterized by a high level of robustness.
  • a radially resilient element can expediently be arranged between the upper region of the bearing housing and the outer housing.
  • This radially resilient element can consist of metal and can be, for example, a spiral spring.
  • an element made of an elastomer or the like can also be used for this.
  • the outer housing can have a flange for fastening in a spinning machine, with a cavity in the flange area for arranging the radially resilient
  • the resilient element can also have only a small radial extension and therefore a relatively large length in the axial direction. Also the arrangement of several resilient elements that complement each other in their effect is possible. To protect the radially resilient element from deformation, a deflection limit can also be provided. This is particularly advantageous in the case of spindles driven by a tangential belt, in which high radially acting braking forces occur. Additional damping of the movement of the bearing housing in the outer housing can be achieved by providing a damping medium such as grease, oil or polymer foam in an intermediate space between the bearing housing and the outer housing.
  • a damping medium such as grease, oil or polymer foam
  • a spirally wound and oil or grease-filled damping element for example a wound sheet metal strip, can also be arranged there.
  • the joint between the bearing housing and the outer housing can expediently be made of a different material than the housing.
  • Composite materials can also be used, e.g. B. a PTFE-coated ball joint.
  • Noise can also be reduced by using a membrane that is matched in geometry and material.
  • the relative position of the bearing housing and the outer housing can be adjusted, for example in the foot area, by means of a screw or clamp connection between the bearing housing and the outer housing.
  • adjustment by plastic deformation of a connecting element is also conceivable.
  • the setting of the relative position in the The upper area can be made, for example, by accommodating the spring element in two interlocking disks with an eccentric bore.
  • fuses can be provided, for example in the form of stops against axial movement of the bearing housing relative to the outer housing. Such security is useful in both directions.
  • FIG. 1 shows a central longitudinal section through a first embodiment of a spindle bearing
  • FIG. 2 shows a central longitudinal section through a second embodiment of a spindle bearing.
  • the bearing housing 10 consists of a bearing housing 10 in which one of a neck bearing 11 and a foot bearing 12th existing lockers storage is arranged.
  • the foot bearing 12 is arranged to be movable in the radial direction in the bearing housing 10.
  • the neck bearing 11 is firmly connected to the bearing housing 10 via a press connection.
  • a damping spiral 13 is provided between the foot bearing 12 and the inner wall of the bearing housing 10.
  • the bearing housing 10 completely closes the actual spindle receptacle from the outside.
  • the inner structure of the bearing housing 10 shown is only an example. Other arrangements of neck bearing 11 and foot bearing 12 are also possible here.
  • the bearing housing 10 is inserted into an outer housing 14 and is mounted on the outer housing 14 in its foot region 10.1 via a joint 15, which here is formed by a tip 16 on the bottom of the bearing housing 10 and a correspondingly shaped hollow tip 17 on the outer housing 14.
  • the bearing housing 10 is arranged in the radial direction in a springy manner in the outer housing 14 via a spring element 18, which is formed here by a plurality of spiral springs arranged one above the other.
  • Grease is filled in as a damping medium in a space 19 between the bearing housing 10 and the outer housing 14. The fill level of the grease in the intermediate space 19 and the spring characteristic of the spring element 18 can easily compensate for the effects of the joint 15 on damping and suspension.
  • the bearing housing 10 In its upper region 10.2, the bearing housing 10 is provided with a press-in collar 20 for axial pull-off protection in the outer housing 14.
  • a cover plate 21 is placed on the outer housing 14 from above, which forms both a seal of the interior of the outer housing 14 and an axial and radial stop for the inner housing 10.
  • a centering device 22 for the joint 15 is provided on the lower region of the outer housing 14. With their help, the relative position of the bearing housing 10 to the outer housing 14 can be adjusted.
  • the inner housing 30 has the same inner structure as the inner housing 10 Fig. 1 on.
  • the foot region 30.1 of the bearing housing 30 rests on an elastic membrane 31 of an outer housing 32, which thus forms a spring joint for the bearing housing 30.
  • a pre-setting of the relative position of the bearing housing 30 to the outer housing 32 is possible via a centering device 33.
