Abstract

To facilitate the replacement of worn spinning rings 1 in ring spinning machines and to accelerate, it is proposed to equip the spinning rings with highly wear-resistant, interchangeable pressed into the body 2 of the spinning rings or einklippsbaren tread rings 3. The spinning runners then glide exclusively on the tread rings optimized for this purpose.

Description

Technical area

The The invention relates to a spinning ring for ring spinning machines.

State of the art

spinning rings serve to guide the revolving, the yarn on the cop spinning spinners. The spinning rotor rotate at near spindle speed and reach speeds of 35 m / sec and more. At least during spinning of No targeted lubrication, lubrication is only possible here grated fibers or by adhering to the cotton fibers small amounts offered by vegetable wax.

Especially the spinning runners are therefore subject to high wear and must be replaced after a few days become. But also the spinning rings are subject to wear and need the Replace after months or years. Here is the exchange of Spinning rings much more complex than the replacement of the comparatively cheap pilots. So have to the new spinning rings are usually re-adjusted. The intervals between the replacement of the spinning rings depend on the rotor speed, the lubricating fiber abrasion, but also the wear of the material pairing Spinning rotor / spinning ring and is between months and years.

It is known to provide the running surfaces of spinning rings with highly wear-resistant coverings. In the DE 195 27 273 A1 For example, an embodiment is disclosed in which spinning rings are coated with a layer of metal-phosphorus or metal-boron in a thickness of 5 microns and 100 microns. If this layer is worn, the spinning ring must be removed and replaced with a new or a newly used with this layer spinning ring. The complex replacement of the spinning ring is therefore not avoided even with such a wear layer.

General description of the invention

Of the Invention was therefore the task of replacing the spinning rings to simplify, accelerate and cheapen. She solves this task by those mentioned in the characterizing part of the independent claim Characteristics.

Of the alone the spinster leading on its circulation Tread ring consists according to the invention of high wear resistant Material, in particular of steel or its wear-resistant Alloys. But it can also consist of ceramic, with high wear resistance across from the steel ones spin runners can be made.

Thereby, that only the tread ring held in the body of the spinning ring replace, this body can remain in the ring rail and does not need to be readjusted when changing the tread ring to become. Replacing the clipped in the body or pressed tread ring is not much more expensive than changing the spinning machine.

During the Tread ring made of highly wear-resistant Alloy, the body can be made of inexpensive material such as sheet metal or plastic, which are easily brought into the required shape can.

The Making the tread ring is very easy if it has a circular cross-section. However, he can also any other, seem appropriate cross-section exhibit. Preferably, its cross-sectional shape is determined by the tread, he's the spinster presents.

Specific description of the invention

In the figures of the drawing is an embodiment of the invention shown. Show in it

1 the cross section through a first embodiment of a spinning ring;

2 the cross section through a second embodiment of a spinning ring.

The spinning ring according to the invention 1 has a body 2 in which a tread ring 3 is held replaceable. This tread ring offers a spinning frame 4 the tread 5 how 1 Recognizable, touches the spinning machine 4 on his circulation only the tread 5 but usually not the body 2 of the spinning ring 1 ,

The body 2 is attached in one of the common ways in a ring rail. This can be done by clamping rings, by spider ring holder, by screwing or otherwise.

The tread ring 3 can in the body 2 be pressed, the body is made of metal such as steel, for example. The body can also be molded from plastic. This can be hard, brittle plastic in the tread ring 3 is also einpressbar. But it can also be used softer, elastic plastic, in which the tread ring is pressed or clipped. The body has for this purpose a hollow profile, which with a lip 6 partially engages an inserted tread ring.

When the tread ring 3 worn out, he can get out of the corpus 2 removed and replaced by a new tread ring. Since the body remains in its place, the new tread ring takes exactly the position and location of the old ring, a readjustment is not required. The replacement of the tread rings is relatively easy and is fast, especially if the tread rings are only pressed or clipped into the body.

The tread rings 3 Advantageously wise circular cross-section, they are therefore much cheaper to produce than conventional, a complicated profile having spinning rings.

How out 2 can be seen, a tread ring 3 ' also have non-circular cross-section, it can then be shaped so that it is the spinster 4 offers a larger contact area. Such a tread ring is subject to less wear and stabilizes the spinning rotor in its position when circulating on the spinning ring.

It is understood that tread rings can be produced and used with any cross-sectional shape. So can a tread ring after 2 on its upper side have a recess, which through the spinning ring 4 current thread provides a larger passage area.

Also the body 2 the spinning ring facing outer surface of a tread ring may be adapted to the nature of its fastening in the spinning ring.

The easy replacement and low cost of tread rings also often allow it not in the choice of their material to the economic limit lowest possible Wear too go, but rather earlier Exchange to accept.
