Description of the invention: [Technical field to which the invention belongs] The surface of the open-end spinning rotor that is in contact with the fiber, on the one hand, can achieve good spinning conditions in the case of various greatly different fiber materials, and on the other hand, hope With a long service life, Bei also protects 5 Dong to prevent wear. "The surface in contact with the fiber", as is well known to the expert, is primarily a fibrous sliding surface or a fibrous acquisition layer. The fiber running to the fiber sliding lunar surface is stored in the conventional manner to the open end spinning rotor 'sliding into the fiber collecting groove by the ^^ & fiber/bone surface, and the spinning rotor is rotated by the open end π At this point, a fiber ring CFaserring is formed, English: fib i ) ^ The line produced by the 4 fiber ring is used for the 'today's main material. The guiding fiber of the end spinning rotor =! Record, stone coating 'This coating consists of a nickel dispersion layer with embedded diamond particles. The zinc separator has a thickness of generally 20 to 50 #ro' and the particle size is between 1 and 2, and an example thereof can be cited as DE 29 09 73 9 C2. [Prior Art] The diamond particles are given a certain roughness to guide the 轳- 守 '丨 fiber, quasi-surface. When all the fiber materials are spun on 2, the granules can ensure good yarn: d two fibers The material 'especially the % of the raw meal containing high levels of contaminants, this rough surface 造成 causes significant contamination in the area of the fiber collection trough and thus causes breakage. Therefore, in the case of the application of the invention, the quality of the yarn of the fiber collecting groove of the surface of the surface which is partially unapplied, or the surface of the fiber that is only drilled or nickel-plated. It is also much worse. Xi Ren has. 5 rt: Some conventional open-end spinning rotors, which allow only the fiber to slide; the mouth end: stone coating' but the fiber collecting groove has no diamond particles. An example of this m can be found in Acts 33 39 852 A1. In this case, the particle size of the diamond particles is selected to be larger, and there is a 1~6 #m ’ point which makes the fiber sliding surface phase rough, which makes the smooth fiber of the body stretch. No diamonds Quality Han phased IT will not be contaminated, so the quality of the machine will be significantly worse. There are other fiber-converting materials, such as sythetik or yake, which are initially poorly slipped, so a smoother fiber sliding surface should be used here. However, due to the recognition of the 4th group and the use of the right ten, the monthly fiber material is less likely to be contaminated, so it is hoped that the coarser fiber will be used for the squeezing of the fiber. quality. It is better than "3". The oral quality is better due to the combination of fibers. Therefore, it is proposed in the German Patent No. 1 97 43 597 to make the sliding surface of the fiber-collecting fiber more griffig. The method is to apply a plurality of nickel-diamond coatings with diamond particles of non-particle size on top and bottom. The diamond layer below b has larger diamond particles. In this case, there is a small diamond particle. The upper nickel-diamond layer, especially in the fiber collection tank*, will be released more than 'because the wire and fiber loops produced there are particularly well-known on the surface. On the fiber sliding surface, the wear is small, so The diamond particles having a smaller particle size remain there without losing. Therefore, over time, the fiber collecting groove of the open π-end spinning rotor is thicker than the fiber sliding surface. DE 1 13 3 5 9 A1 mentions a similar effect q. According to this, when the nickel-diamond layer is produced, the material has an influence on the particle size, so that the hardness of the hard particles occurring on the moving surface of the fiber is higher than that in the fiber collecting tank. Second: and, in the fiber collection tank The thick chain is larger than the fiber sliding surface (when the layer thickness remains approximately the same). Finally there is a compromise measure 'in DE 1 98 22 265 A1 k to. One will have 5 ~ 丨 n to 111 The thicker carrier layer of the diamond particles is covered with a working layer having a Μ ^ 3 J weight/disgracement of 1 to 2. 8" m of diamond particles, wherein the diamond particles are as if they are teeth, so, as described, the work The layer is held firmly on the carrier layer. In lean magnetic < ^丄 m . The species is also 50, although the fiber sliding surface and the fiber receiving trough lock 1 stone coating and the system is treated as (4) in 1 aspect, especially in the second layer of the layer thickness method (10) 198 22 265 A1, Μ ~31 Order). The particle size of the open end stone particles in the above-mentioned nickel-diamond coating is much larger than i^. The present invention relates to a spinning rotor with an open end sliding surface and an opening of a fiber collecting groove, and the basin layer itself is covered by a brocade The brocade is composed of a dispersion layer.

因此本發明的一個很重要的特點在於：該鑽石顆粒的 尺寸只在迄今習用的顆粒尺寸的約1/1〇的度量級。特別是 當鑽石顆粒的體積比例佔鎳-鑽石覆層的2〇〜4〇%時，這= 還可在已具有充分的光滑度的場合時提供某種粗糙度。上 述的矛盾當然並不會如此就消失，但會呈現出在實用上可 接受的形式而減緩。事實顯示，利用本發明此特點，在紗 品質與紗收集槽防污染性（即運轉性質）之間可達到一平 衡點。小的顆粒尺寸造成較「細緻」肖不會附著污染物的 表面，其中紗品質固然略低於習用技術具高粗糙度表面者 之最佳品質’但仍完全可接受。 為了要有夠長的使用壽命’依本發明的設計係使錄分 散體層厚度為20〜且不與纖維接觸的鑽石顆粒的尺 寸為0.1〜0·4μι如此，即使在該開口端紡炒轉子在較長 時使用後仍能確保紗品質不改變。 對於上述情形--亦即纖維收集槽要比纖維滑動面更 粗糙一一上述已引述的先前技術DE 1 97 43 597 Μ可利用 本發明如下述改裝：使該鎳分散體層由—較厚的基層及一 較薄的蓋層構成，且其蓋層的鑽石顆粒尺寸為U〜〇 m，而基層的鑽石顆粒則大得多。該2〇〜5Mm厚的基層的 顆粒大小，舉例而言，可為1〜4 从m，而上述較小的顆粒尺 寸只位在蓋層中’蓋層厚度舉例而言.，約一。由於在纺 8 1334454 紗時發生磨損，故蓋層在操作幾小時内就在纖維收集槽中 釋出，而在纖維滑動面中該蓋層在開口端紡紗轉子的整段 使用壽命中都保持不變。 本發明其他優點及特點見於以下說明及實施例。 【實施方式】 第1圖所示的開口端紡紗轉子（丨）呈習知方式具有一轉 子盤（2)及一與該轉子盤牢接成不能相對轉動的方式的幹 軸（3)。該轉子盤（2)之開放的前側（4)係朝向開口端紡紗嘹 備的操錢，且在操作時用―蓋件（圖未示）以^接觸^ 式封閉。Therefore, a very important feature of the present invention is that the size of the diamond particles is only about 1/1 〇 of the particle size conventionally used. In particular, when the volume fraction of the diamond particles accounts for 2 〇 to 4 〇% of the nickel-diamond coating, this = can also provide a certain roughness when it has sufficient smoothness. The above contradictions certainly do not disappear, but they will appear to be slower in a practically acceptable form. It has been shown that with this feature of the invention, a balance point can be achieved between yarn quality and the anti-contamination (i.e., operational nature) of the yarn collection trough. The small particle size results in a surface that is less adherent to the "fine", where the yarn quality is slightly lower than the best quality of conventional high-roughness surfaces, but is still fully acceptable. In order to have a long enough service life, the design according to the present invention is such that the size of the dispersion layer having a thickness of 20 Å and not in contact with the fibers is 0.1 to 0.4 μm, even if the rotor is spun at the open end. It can still ensure that the yarn quality does not change after a long time of use. In the case of the above-mentioned, that is, the fiber collecting groove is rougher than the fiber sliding surface, the above-mentioned prior art DE 1 97 43 597 Μ can be modified by the invention as follows: the nickel dispersion layer is made of a thicker base layer And a thin cover layer, and the cover layer has a diamond particle size of U ~ 〇m, while the base layer of diamond particles is much larger. The particle size of the 2 Å to 5 Mm thick base layer may, for example, be 1 to 4 from m, and the smaller particle size described above is only in the cap layer. The thickness of the cap layer is, for example, about one. Due to the wear during the spinning of the 8 1334454 yarn, the cover layer is released in the fiber collecting tank within a few hours of operation, while in the fiber sliding surface the layer remains in the entire life of the open end spinning rotor. constant. Other advantages and features of the present invention are found in the following description and examples. [Embodiment] The open-ended spinning rotor (丨) shown in Fig. 1 has a rotor disk (2) and a dry shaft (3) in such a manner as to be inseparable from the rotor disk. The open front side (4) of the rotor disk (2) is operated toward the open end spinning device and is closed by a cover member (not shown) during operation.

The fiber sliding surface (5) is tapered to the -fiber collecting groove (4)'. The fiber collecting groove (4) causes the maximum inner diameter of the open end yarn accessing rotor (1). The fiber slides on the fiber sliding surface (5) under the centrifugal force of the rapidly rotating rotor disk to slide the fiber collecting groove (8), and the fiber double-bonded (the wire (10) catches the dGubling) to form a fiber ring ( FaSering), then the fiber loop is pulled out of the resulting line. The surface (7) for the fiber introduction fiber (especially the surface (7) of the fiber sliding surface (5) and the fiber collecting groove (6)] is indicated by a broken line in the upper portion of the first drawing. Some surfaces (7) have a nickel-diamond coating (8)' as shown in the high magnification of Fig. 2 (=: the town 'stone coating (8) itself consists of a recording dispersion layer (indicated by hatching) in a conventional manner' Its thickness d, and has incorporated diamond particles (10) (10'); at least one right + μ = one or two diamond particles (10) [they are out of the nickel S dog and in contact with the fiber] and its particle size is G .1~〇.4 9 1334454 In the embodiment of the second embodiment, the size of the diamond particles (1), which are not in contact with the fibers, is 八··1 to 0.4 (4). Thus, in a practical situation, the above-mentioned::Shield can be moderated. This contradiction lies in that on the one hand, for good yarn quality, = (four) fiber collecting grooves (8), on the other hand, it is desirable to have less dirt and the fiber is to be as smooth as possible. The thickness d of the bulk layer (8) is preferably 2 〇 to • m. The volume ratio of diamond particles (1〇) (1〇') is about 20~40% of the recorded diamond. Another embodiment of the surface (7) for guiding fibers of Figures 3 and 4 is provided with a further H diamond coating (8) which is in the new state in Figure 3 and the open end in Figure 4 The rotor (1) has been running for a period of time, and both figures are enlarged in high magnification. • According to Fig. 3, a nickel-diamond coating (8) consists of a thicker base layer (ι) and a thinner cover layer (12). The base layer (11) has a thickness of about 2 〇 to 5 (m), and the cover layer (12) has a thickness of only about 5/zm. The size of the diamond particles (13) in the base layer (11) is 1 to 4/m. The size of the diamond particles (1 〇) in the cap layer (12) is in the range of 0·1 to 0.4/zm according to the present invention. This design allows only a small particle size in the new state of the rotor disk (2). The diamond particles (丨〇) are in contact with the fibers. However, this thinner cover layer (12) has been released in the fiber collection tank (6) after several operating hours because the fiber loops present there are due to the production of the wire. This is rotated, whereas the surface (7) of the fiber sliding surface (5) does not wear significantly over the life of the rotor disk (2). Therefore, after several operating hours, 'in the fiber collecting tank (6) The state of Fig. 4 occurs in which the cap layer (12) of the diamond particles (10) having a small particle size is almost completely released, and only the base layer (11) of the diamond particles (13) having the particle size is still in effect. The fiber 1334454 dimensional sliding surface (5) is in the state shown in Figure 3. As is known from the prior art principles described above, a guiding fiber is created. Surface (7), wherein the fiber sliding surface (5) is less rough than the fiber collecting groove (6). However, according to the present invention, unlike the prior art, the nickel-diamond coating (8) is in a new state. The particle size on the surface of the diamond particle (10) is only ~〇. 4 # m.
