Description
【０００１】[0001]
本考案は、Ｘ線管、特にその陽極取付構造に関する。 The present invention relates to an X-ray tube, and more particularly to an anode mounting structure thereof.
【０００２】[0002]
回転陽極Ｘ線管の陽極重量が増すにつれ、その陽極ターゲットの固定方法が重 要となる。従来ターゲットとローターとは機械的接合（ネジ・ナットによる）も のが一般的であった。また他の例として、ターゲットとローターを鑞付けする方 法も考えられた。 As the weight of the rotating anode X-ray tube increases, the method of fixing the anode target becomes important. Conventionally, the target and rotor were usually mechanically joined (by screws and nuts). As another example, a method of brazing the target and the rotor was also considered.
【０００３】[0003]
しかしながら、前者では陽極の起動・制動を繰り返すと、緩みが発生し、振動 や騒音の原因となっていた。また後者では、ターゲット単体でなく、ローターと ともに鑞付けする必要があるため、鑞材およびその融点（又は鑞付け温度）は制 約され、比較的低融点の鑞材を用いなければならない。そして、鑞付けした際に 鑞材が不必要な箇所まではい出ると、Ｘ線管の作動中はターゲットが約１０００ ℃の高温であるため、この鑞材が蒸発し、真空度劣化やＸ線管容器の内面外囲器 への金属蒸着を招き、ついには耐電圧不良に至る。 However, in the former case, when the anode was repeatedly started and braked, loosening occurred, causing vibration and noise. In the latter case, the brazing material and its melting point (or brazing temperature) are restricted because it is necessary to braze the target together with the rotor, and a brazing material with a relatively low melting point must be used. When the brazing material comes out to an unnecessary point when brazing, the target is hot at about 1000 ° C during the operation of the X-ray tube, so this brazing material evaporates and the degree of vacuum deterioration and X-ray This causes vapor deposition of metal on the inner envelope of the tube container, which eventually leads to defective withstand voltage.
【０００４】 本考案は上記課題を解決し、鑞材が不必要な部分にはい出さないようにしたＸ 線管を提供することを目的とする。An object of the present invention is to solve the above problems and to provide an X-ray tube in which a brazing material does not stick out to an unnecessary portion.
【０００５】[0005]
上記課題を解決するため、本考案の構成は次のとおりとする。即ち、ロータ軸 の先端付近にフランジが設けられ、該フランジの端面に接して陽極円板が前記ロ ータ軸を貫通させ、前記ロータ軸に螺合したナットと前記フランジとの間で前記 陽極円板が挟持されたＸ線管において、前記フランジと前記陽極円板との円環状 鑞付け面の半径方向外側で、前記フランジと前記陽極円板の少なくとも一方に１ または複数の鑞材はい出しを阻止する円周溝が設けられたことである。 In order to solve the above-mentioned subject, the composition of the present invention is as follows. That is, a flange is provided in the vicinity of the tip of the rotor shaft, and the anode disk is in contact with the end surface of the flange to penetrate the rotor shaft, and the anode is inserted between the nut screwed to the rotor shaft and the flange. In an X-ray tube having a disc sandwiched between the flange and the anode disc, one or more brazing members are laid out on at least one of the flange and the anode disc radially outside the annular brazing surface. That is, a circumferential groove for preventing the above is provided.
【０００６】[0006]
鑞付け作業に際し、鑞付け面を越えて鑞材が流れ出ても、円周溝に滞留し、鑞 材はフランジ部の周縁までは達しない。 Even when the brazing material flows out over the brazing surface during brazing work, it remains in the circumferential groove and the brazing material does not reach the peripheral edge of the flange.
【０００７】[0007]
以下に本考案の実施態様を図面に示す一実施例にもとづき説明する。 An embodiment of the present invention will be described below based on an embodiment shown in the drawings.
【０００８】 図１において、ロータ軸１の先端付近にフランジ２が一体形成され、該フラン ジ２の一端面に接して陽極円板３が前記ロータ軸１を貫通させ、前記ロータ軸１ に螺合したナット４と前記フランジ２との間で前記陽極円板３が挟持されている 。In FIG. 1, a flange 2 is integrally formed near the tip of a rotor shaft 1, and an anode disk 3 penetrates the rotor shaft 1 in contact with one end face of the flange 2 and is screwed to the rotor shaft 1. The anode disk 3 is sandwiched between the fitted nut 4 and the flange 2.
【０００９】 しかして、前記フランジ２と前記陽極円板３との円環状鑞付け面２ａ，３ａの 半径方向外側で、前記フランジ２には鑞材はい出しを阻止する円周溝２ｂが設け られる。２ｃは、鑞付け作業に先立って鑞材を収容する鑞材溝である。[0009] Thus, on the outer side in the radial direction of the annular brazing surfaces 2a, 3a of the flange 2 and the anode disk 3, the flange 2 is provided with a circumferential groove 2b for preventing the brazing material from protruding. . Reference numeral 2c is a brazing material groove for accommodating the brazing material prior to the brazing work.
【００１０】 従って、鑞付け時に鑞材溝２ｃに針金状または細帯状の鑞材の細片が収容され る。次に陽極円板３がロータ軸１を貫通させて嵌められ、ナット４で締結される 。次に、これらが鑞付け炉内に入れられて鑞付けされる。このとき、鑞付け面３ ａを越えて鑞材が流れ出ても、前記円周溝３ｂに滞留し、鑞材はフランジ部２の 周縁までは達しない。Therefore, a wire-shaped or strip-shaped strip of the brazing material is housed in the brazing material groove 2c during brazing. Next, the anode disk 3 is fitted through the rotor shaft 1 and fastened with the nut 4. Next, these are put into a brazing furnace and brazed. At this time, even if the brazing material flows out over the brazing surface 3 a, it remains in the circumferential groove 3 b and does not reach the peripheral edge of the flange portion 2.
【００１１】 図２は他の実施例を示し、陽極円板３には円周溝３ｂが設けられたものである 。FIG. 2 shows another embodiment in which the anode disk 3 is provided with a circumferential groove 3b.
【００１２】 図３は更に他の実施例を示し、鑞付け面２ａ’が他の部分より僅かに低く（約 １０〜１００μｍ）形成される。これにより、円周溝２ｂの半径方向外側の面が 陽極円板３の位置決め面となるので、組立時の精度が向上すると共に、鑞付け隙 間が一意的に決められる。FIG. 3 shows still another embodiment, in which the brazing surface 2a 'is formed slightly lower than other portions (about 10 to 100 μm). As a result, the surface on the outer side in the radial direction of the circumferential groove 2b serves as the positioning surface for the anode disk 3, so that the accuracy during assembly is improved and the brazing gap is uniquely determined.
【００１３】 前記円周溝３ｂは複数設けてもよく、また、陽極円板３に、或いはこれらの両 方に設けてもよい。A plurality of the circumferential grooves 3b may be provided, and the circumferential groove 3b may be provided on the anode disk 3 or on both of them.
【００１４】 本考案は前記した実施例や実施態様に限定されず、実用新案登録請求の精神お よび範囲を逸脱せずに種々の変形を含む。The present invention is not limited to the above-described embodiments and embodiments, and includes various modifications without departing from the spirit and scope of the utility model registration request.
【００１５】[0015]
本考案の構成により、鑞付け作業に際し、接合面から流れ出した鑞材は溝に溜 まり、それ以上は流れ出さず、蒸発による耐電圧不良などの不具合が生じない。 According to the configuration of the present invention, during brazing work, the brazing material flowing out from the joint surface is collected in the groove and does not flow further, and problems such as defective withstand voltage due to evaporation do not occur.
