Abstract

Device for attaching spindle bearing housings of ring spinning machines, on a preferably cylindrical holding tube, characterized in that a flexible clamping band (7, 8) is provided, which at one end to a retaining pin (11) on the spindle bearing housing (1) suspended and after wrapping at least a part of the circumference of the holding tube (3, 4) with its other end via a tensioning element attached to the spindle bearing housing (12, 13, 14) is tightened tightened.

Description

In the DD 29 797 A discloses an apparatus for securing spindle bearing housings to two parallel, adjacent support tubes. The fastening takes place by means of clamping pieces, which surround the holding tubes. For this purpose, clamping pieces are required, which require machining. Clamping connections of this type have the advantage that the support members require no division-dependent machining for the attachment of retaining elements such as screws. Rather, the components can be readily mounted in any, in particular the uniform pitch of the jobs.

The DE 2 014 490 A shows a tubular support for the spindle bearing housing. Aligning the spindle bearing housings must be carried out with minimum tolerances so that the spindles are still exactly centered in the associated ring at their tips. The spindles can be pre-assembled in the factory on devices very accurately on carriers extending from intermediate stand to intermediate stand. A single pipe for this purpose is a simple structural measure. It has been shown that these are preassembled only one tube spindle bearing housing during transport are very exposed to the risk of displacement, in particular twisting around the pipe and their exact assembly is impaired.

The DE 35 28 023 C1 introduces a tensioning band attachment for supply lines also on only one pipe. When supply lines are placed on the accuracy of the arrangement only very small claims that can be met here easily by a strap on only a tubular support.

The DE 31 45 798 C2 discloses a Luntensperrvorrichtung at a drafting of a spinning machine, which is also attached to only one cross-sectionally circular rod by means of a clamping band. On the accuracy and compliance with the setting of such devices, which attack only small forces, also low demands are made, which can be met by means of a tension band readily.

This is especially true for the subject matter of DE 494 978 A for fixing a lighting device to a sewing machine. Here, the arrangement of the device in terms of height, angle, inclination, etc. is deliberately left as much freedom. The strength of the arrangement is of minor importance, it can be easily restored in the event of decay.

Of the Invention was the task, a simpler, less expensive Type of fastening, in particular for fastening spindle bearing housings of Ring spinning machines on two parallel holding tubes or Specify rods. But the invention is also for attachment of spindle bearing housings suitable for only one holding tube.

In a first embodiment is the device for attaching a spindle bearing housing at least suitable for a holding tube. She has a flexible strap with holes near his both ends, with the one end in a pin-shaped holding member on the spindle bearing housing and with its other end in an attacking on the spindle bearing housing Clamping device can be suspended is, by means of which the circumference of the spindle bearing housing partially wrap around strap is clamped.

If a holding tube is cylindrical, the resistance depends on Turning the spindle bearing housing around the holding tube visible from the clamping force of the clamping band, from the coefficient of friction between tension band and holding tube and others Influencing factors from and is limited by these. To avoid this limitation, the holding tube or the support rod out of round, for example, be elliptical.

The Device is therefore advantageous for attaching a spindle bearing housing used two parallel holding tubes. Here are two in opposite directions straps in reverse order put the two holding tubes and through a clamping device, in the two tension bands intervene, stretched together. There is no danger that itself the spindle bearing housing turns around the two holding links.

In a second embodiment for attaching a spindle bearing housing to two parallel Holding links is a longer, pliable strap provided, both of which provided with holes Ends in pen-shaped Holding pins inserted and the two strands of the strap by means of one between the two holding ears relative to the spindle bearing housing Tensioned tendon.

In the figures of the drawing are embodiments of the devices shown. Show in it

in the Subsequently, the invention will be applied in its application to fastening of spindle bearing housings shown and described. It is understood that the invention also for fastening in front of other components of spinning machines can be used with advantage.

In the 1 and 2 are spindle bearing housings 1 represented by their spindles 2 only the axes are indicated. The spindle bearing housings are each on two holding tubes 3 and 4 attached and have for this purpose semicircular recesses 5 on, which are placed on the outer diameter of the holding tubes. The spindle bearing housings are preferably made of die-cast.

In the recesses 5 are grooves 6 deepened, in which in the embodiment of the 1 two flexible straps 7 and 8th preferably made of steel. The dimensions of the clamping bands in terms of length, width, thickness, material depends on their application. For lightweight fasteners with low strength requirements, plastic straps can also be used. Tensioning straps made of plastic have the advantage that they have a higher coefficient of friction than steel and therefore tend less to slide around the holding tube when mounting on only one holding tube. To avoid tearing the holes in plastic straps, their ends receiving the holes may be reinforced by pads, clips or the like.

The in the 3 and 4 Tensioning bands shown in detail 7 . 8th have holes at their ends 9 and 10 on whose edges are crimped on one side. The straps are with their round holes 9 in retaining pins 11 hung in the grooves 6 are arranged. You can put in the bearing housing 1 be used or - if they are made of die - be formed in them. The straps are around the perimeters of the holding tubes 3 and 4 laid and with their elongated holes 10 in frames 12 a pull plate 13 hooked.

For fastening the spindle bearing housings 1 becomes the tension plate 13 by means of a screw 14 pulled against the spindle bearing housing and the tension bands 7 and 8th Tense until tight around the holding tubes 3 . 4 lie.

In the embodiment of the 2 comes a longer strap 15 For use, the only round holes at both ends 9 having. We put one end in the retaining pin 11 in one of the grooves 6 mounted, then the spindle bearing housing 1 on the holding tubes 3 . 4 put on the strap and pushed it into the other groove until it is behind the retaining pin 11 this groove engages. Then a clamping piece 16 placed between the two holding tubes on the strap and by means of the screw 14 pulled against the spindle bearing housing until the two strands of the tension band 15 tight around the holding tubes 3 . 4 are drawn.
