DD235281A1 - ADJUSTABLE SPINDLE MOUNTING FOR RING SPINNING OR RINGING MACHINES - Google Patents

Abstract

The invention relates to an adjustable spindle attachment for ring spinning or ring twisting machines, in which a Lagergehaeuse a spindle is disposed in an opening of a Spindeltraegers, rests with a Lagergehaeuseflansch on the spindle carrier and is provided below the Spindeltraegers with a screw, wherein between the Lagergehaeuseflansch and the Spindeltraeger a plastically deformable annular disc is arranged. The aim of the invention is to achieve a work facilitated by the reduction of the power requirement during the deformation of the plastically deformable annular disc in the centric adjustment of the spindle to the ring. The technical problem, which is solved by the invention, is to reduce the deformation resistance of the plastically deformable annular disc. According to the invention, this is achieved by arranging at least three support surfaces (10) distributed over the circumference on the annular disc (3, 12, 13). Fig. 2

Description

Field of application of the invention

The invention relates to the field of spinning and twisting and relates to an adjustable spindle attachment for ring spinning or ring twisting machines, in which a bearing housing a spindle is disposed in an opening of a spindle carrier, is provided with a bearing housing flange on the spindle carrier with a screw, wherein between the bearing housing flange and the spindle carrier a plastically deformable annular disc is arranged.

Characteristic of the known technical solution

In an adjustable spindle attachment for ring spinning or ring twisting machines, in which a bearing housing a spindle is disposed in an opening of a spindle carrier, rests with a bearing housing flange on the spindle carrier and is provided below the locker.'trägers with a screw, has been proposed that to the spindle carrier facing end side of the bearing housing flange a plastically deformable region is arranged (DD invention application WP D 01 H / 266 715 4). The plastically deformable region consists of a ring. The disadvantage here is that the centric adjustment of the spindle to the ring requires a large amount of force to achieve the deformation of the plastically deformable ring.

Object of the invention

The application of the invention has the goal to achieve a work easier in the central adjustment of the spindle to the ring by reducing the power requirement in the deformation of the plastically deformable annular disc.

Explanation of the essence of the invention

The invention has for its object to reduce the deformation resistance of the plastically deformable annular disc. According to the invention, this object is achieved in that at least three distributed over the circumference bearing surfaces are arranged on the annular disc.

embodiment

To the accompanying drawings show

1: the front view FIG. 2: the section A-A according to FIG. 1 FIG. 3: the section A-A according to FIG. 1 FIG. 4: the section A-A according to FIG.

With an adjustable spindle attachment for ring spinning or ring twisting machines, a bearing housing 1 (FIG. 1) of a spindle 8 is arranged in an opening of a spindle carrier 4. The bearing housing 1 rests with a bearing housing flange 2 on the spindle carrier 4 and is provided below the spindle carrier 4 with a screw connection. The screw connection consists of a threaded portion 5 located on the bearing housing 1, a washer 6 and a hexagonal nut 7. Between the spindle support 4 and the bearing housing flange 2, a plastically deformable annular disc 3 is arranged. On the annular disc 3 four distributed over the circumference bearing surfaces 10 are arranged. The annular disc 3 rests with the bead 11 on the circumference of the bearing housing flange 2 (FIG. 2). The spindle is assigned a ring 9.

The mode of action is the following:

By applying a bending moment on the bearing housing 1 below the threaded portion 5, the spindle 8 is pivoted, and indeed so far until a centric Stel'ung the spindle 8 is reached to the ring 9. The contact surfaces 10 located on the annular disc 3 are plastically deformed by the applied bending moment. The not yet tightened hex nut 7 on the threaded portion 5 is tightened after the achieved centering position of the spindle 8 to the ring 9 and thus keeps the bearing housing 1 in the set position on the spindle carrier 4 fixed.

In another embodiment, the annular disc 12 is formed divided (Fig. 3). In a further embodiment, a slot 14 and three bearing surfaces 10 are arranged on the annular disc 13 (Fig. 4). The mode of action is the same as that previously described. With regard to the number of contact surfaces 10, it is such that at least three are arranged.

Characteristic of the known technical solution In an adjustable spindle attachment for ring spinning or ring twisting machines, in which a bearing housing a spindle is disposed in an opening of a spindle carrier, rests with a bearing housing flange on the spindle carrier and is provided below the spindle carrier with a screw, has already been proposed that on the spindle carrier facing end face of the bearing housing flange a plastically deformable region is arranged (DD invention application WP D 01 H / 266 715 4). The plastically deformable region consists of a ring. The disadvantage here is that the centric adjustment of the spindle to the ring requires a large amount of force to achieve the deformation of the plastically deformable ring.

In an adjustable Spindeibefestigung for ring spinning or ring twisting a bearing housing 1 (Fig. 1) of a spindle 8 in an opening of a spindle support 4 is arranged. The bearing housing 1 rests with a bearing housing flange 2 on the spindle carrier 4 and is provided below the spindle support 4 with a screw connection. The screw connection consists of a threaded portion 5 located on the bearing housing 1, a washer 6 and a hexagonal nut 7. Between the spindle support 4 and the bearing housing flange 2, a plastically deformable annular disc 3 is arranged. On the annular disc 3 four distributed over the circumference bearing surfaces 10 are arranged. The annular disc 3 rests with the bead 11 on the circumference of the bearing housing flange 2 (FIG. 2). The spindle is assigned a ring 9.
