本発明はスライドブツシュにおける保持器の製造法に関
するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for manufacturing a cage in a sliding bush.
従来から、外筒と、外筒に挿入される軸と、外筒と軸と
の間に配される鋼球と、鋼球が脱落しな０ように鋼球を
保持する為の保持器とから成るスライドブツシュは多種
市販されている。Conventionally, an outer cylinder, a shaft inserted into the outer cylinder, a steel ball disposed between the outer cylinder and the shaft, and a retainer to hold the steel ball so that the steel ball does not fall out have been used. There are many types of slide bushes available on the market.
このスライドブツシュにおける保持器は一般に金属製の
ものと合成樹脂製のものとがある。The cage in this slide bushing is generally made of metal or synthetic resin.
金属製の保持器は、金属プレートをプレス成型したり、
また薄肉の金属パイプをプレス成型したりして製作する
もので、金属製故に機械的強度の点では秀れているが、
保持器に形成する鋼球走行溝を鋼球径に合致させて形成
することが難しく、この点が鋼球を円滑転動させること
の妨げとなっている。Metal cages are made by press molding metal plates,
It is also manufactured by press-forming thin-walled metal pipes, and because it is made of metal, it has excellent mechanical strength.
It is difficult to form the steel ball running grooves formed in the cage so as to match the diameter of the steel balls, which hinders smooth rolling of the steel balls.
一方、合成樹脂製の保持器は、鋼球走行溝を正確に形成
することは可能であるが、機械的強度。On the other hand, synthetic resin cages allow accurate formation of steel ball running grooves, but lack mechanical strength.
耐久性、耐薬品性等の問題があり該合成樹脂製の保持器
を有するスライドブツシュはその使用場所が限定されて
しまうという問題点を有する。Slide bushings having synthetic resin retainers have problems such as durability and chemical resistance, and have a problem in that the places where they can be used are limited.
本発明はこのような点を解決したもので、金属製保持器
と合成樹脂製保持器との長所を具備したスライドブツシ
ュにおける保持器の製造法を提供することを技術的課題
とするものである。The present invention has solved these problems, and its technical problem is to provide a method for manufacturing a cage in a slide bushing that has the advantages of a metal cage and a synthetic resin cage. be.
添付図面を参照して本発明の詳細な説明する。 The present invention will now be described in detail with reference to the accompanying drawings.
外筒ｌと、外ｉｆに挿入される軸２と、外筒ｌと軸２と
の間に配される鋼球３と、鋼球３が脱落しないように鋼
球３を保持する為の保持器４とから成るスライドブツシ
ュの前記保持器４を金属微粉末による金属射出成形法に
より成型することを特徴とするスライドブツシュにおけ
る保持器の製造法に係るものである。An outer cylinder l, a shaft 2 inserted into the outer if, a steel ball 3 disposed between the outer cylinder l and the shaft 2, and a holder for holding the steel ball 3 so that the steel ball 3 does not fall off. The present invention relates to a method for manufacturing a retainer in a slide bush, characterized in that the retainer 4 of the slide bush consisting of a container 4 is molded by a metal injection molding method using fine metal powder.
第６図に図示した工程による金属微粉末による金属射出

り形成する金属製保持器及び射出成形等により成型する
合成樹脂製保持器のそれぞれの長所のみを有する保持器
４を製造し得ることになる。Since the cage 4 is molded by metal injection molding using fine metal powder according to the process shown in FIG. 6, there are advantages of a metal cage formed by press working etc. and a synthetic resin cage molded by injection molding etc. This means that it is possible to manufacture a cage 4 having only the following.
第１．２．３．４．５図は金属射出成形法により成型し
た保持器４であり、第６図は金属射出成形法の概略図で
ある。1.2.3.4.5 shows the cage 4 molded by the metal injection molding method, and FIG. 6 is a schematic diagram of the metal injection molding method.
ここで、金属射出成形法にって第６図を参照にその概略
を説明する。Here, the outline of the metal injection molding method will be explained with reference to FIG.
まず、該成型法は、１〜４０μｌ程度の金属の微粉末（
例えばステンレス鋼等の微粉末）に容量％で４０％のバ
インダー（有機溶剤）を加えて混練し、射出成型後加熱
脂膜工程を経、その後焼結工程を行ない、後加工して保
持器４を完成させるものである。First, this molding method uses about 1 to 40 μl of fine metal powder (
For example, fine powder of stainless steel, etc.) is mixed with 40% binder (organic solvent) by volume, and after injection molding, a heating oil film process is performed, followed by a sintering process, and post-processing is performed to form a cage. It completes the
金属微粉末はＦｅ系、Ｆｅ−Ｎｉ系、ステンレス鋼系１
等どのような微粉末を用いても良く、用途に応じて種々
選択する。Fine metal powder is Fe-based, Fe-Ni-based, stainless steel-based 1
Any fine powder may be used, and various types are selected depending on the purpose.
また、バインダーは微粉末の形状を保つ為の結合作用と
微粉末粒子間の滑りを良くする滑作用と微粉末に柔軟性
を与える為の可塑作用の二作用を発揮するものを用いる
。Further, the binder used has two functions: a binding function to maintain the shape of the fine powder, a sliding function to improve the slippage between the fine powder particles, and a plasticizing function to give flexibility to the fine powder.
このような金属射出成型法によると、金属微粉末そのも
のの塑性変形を利用しないでバインダー添加により塑性
を得る為、硬い合金粉末が使用できることになり、また
、１〜４０μ度の微細な粉末を利用するため最終的に焼
結体の相対密度を９５％以上と高めることも可能となり
、高密度の保持器４が製作し得ることになる。According to such a metal injection molding method, since plasticity is obtained by adding a binder without using the plastic deformation of the fine metal powder itself, a hard alloy powder can be used, and a fine powder of 1 to 40 μg can be used. Therefore, it becomes possible to finally increase the relative density of the sintered body to 95% or more, and a high-density cage 4 can be manufactured.
これらのメリ、ットは、保持器４の特性に合致するもの
で、高品質の保持器４を製作し得ることになる。These advantages match the characteristics of the cage 4, and it is possible to manufacture a high quality cage 4.
図中符号５は鋼球走行溝、６は無負荷鋼球軌道を構成す
る半溝である。In the figure, numeral 5 is a steel ball running groove, and 6 is a half groove that constitutes a no-load steel ball track.
本発明は上述のようにしたから、鋼球の転勤が非常に円
滑であるとともに耐久性に秀れたスライドブツシュにお
ける保持器を製造し得ることになる。Since the present invention is as described above, it is possible to manufacture a retainer for a slide bushing in which the steel balls are transferred very smoothly and which has excellent durability.
