DE3417501A1 - Mounting of a lower roller for spinning or twisting machines of great length - Google Patents

Abstract

The invention relates to a mounting of a lower roller for spinning or twisting machines of great length, the lower roller being separated into two lower-roller parts, being arranged in stands and mounted in rolling bearings and being driven in the same direction of rotation and at the same rotational speed at the start and at the end, in each case by means of a gear. The object on which it is based is to avoid reducing the production of the machine and to lower the outlay for the mounting of the lower-roller parts. This object is achieved in that the lower-roller parts (2, 3) of the lower roller (1) are received at the parting point in a common stand (4), and a rolling bearing (5, 6) is arranged on each lower-roller part (2, 3) at the parting point. Fig. The invention achieves the technical effect that the full spindle speed of the machine is maintained and the mounting of the lower-roller parts is simplified. <IMAGE>

Bearing of a lower roll for spinning or twisting machines of great length
5

The invention "relates to a mounting of a lower roll for spinning or twisting machines of great length according to the preamble of claim 1.

For spinning machines of great length, it is advantageous to carry out the lower rollers separately in order to twist the Avoid bottom rolls. Separate lower rollers are driven from the start and end of the machine. Warehousing Such lower rolls must be designed taking into account the associated peculiarities.

To meet these requirements, bearings are one Lower roller of the type mentioned is known (DE-OS 1560 233; DE-PS 410 231). The disadvantage is that on a field with six spindles is omitted from the separating point due to the space required for storage, which leads to a reduction in the production of the machine · Another disadvantage is that the storage the lower roll parts at the separation point is expensive.

The invention has for its object to avoid the reduction in production of the machine and the Reduce the cost of storing the lower roll parts.

This task is performed in a device of the generic type solved by the characterizing features of claim 1. In order to have good accessibility to the separation point at To get rid of malfunctions and to carry out maintenance work is in a further embodiment the outer diameter of the rolling bearings is greater than

the largest diameter of the bottom roller.

With the invention, the technical effect is achieved that the full spindle speed of the machine is maintained and the storage of the lower roll parts is simplified will.

An embodiment of the invention is shown in the drawing and will be described in more detail below.

The drawing shows the bearing of a lower roll of a spinning or twisting machine at the cutting point

A lower roller 1 consists of sections screwed together. At the machine ends, the lower roller 1 is mounted in fixed bearings, not shown. the Lower roller 1 for spinning or twisting machines of great length is at the beginning and at the end via a gear in driven in the same direction of rotation and at the same speed and is separated into two lower roller parts 2, 3. At the point of separation, the lower roll parts 2, 3 of the lower roll 1 are received in a common punch 4- On each lower roller part 2, 3, a roller bearing 5 »6 is arranged on the journals 7» 8 at the separation point Rolling bearings 5 »6 are secured against axial displacement with circlips 9» 10. The outside diameter 11 of the rolling bearings 5j 6 is larger than the largest diameter 12 of the lower roller 1.

The mode of action is as follows:

If repairs or maintenance work are necessary on the lower roll 1, the safety

ring rings 9 »10 loosened. Will the repair or maintenance work carried out on the lower roller part 2, the punch 4 is so far to the right over the lower roller part 3 moved until the separation point of the lower roller 1 is exposed. The lower roller part 2 with the one on the journal 7 Rolling bearing 5 located is then lifted out upwards and can in this position on the to be repaired Section can be unscrewed without difficulty · After the repair is finished, it will be again screwed lower roll part 2 down into the work si age brought. The punch 4 is pushed over the roller bearings 5, 6 at the separation point and the retaining rings 9> 10 are reattached. When working on the lower roll part 3 is proceeded accordingly.

Claims (1)

Patent Claims: 1. Storage of a lower roll for spinning or twisting machines of great length, with the lower roll in two Lower roll parts are separated, arranged in punches and stored in roller bearings and at the beginning and at the end is driven via a gear in the same direction of rotation and at the same speed, characterized in that that the lower roller parts (2, 3) of the lower roller (1) at the separation point in a common Punch (4) are added and a roller bearing on each lower roller part (2, 3) at the separation point (5 »6) is arranged. 2, storage of a lower roll according to claim 1, characterized characterized in that the outer diameter (11) of the roller bearings (5, 6) is greater than the largest diameter (12) of the lower roller (1)
