Abstract
Description
【発明の詳細な説明】 本発明は、摺動接点材料の改良に関する。[Detailed description of the invention] The present invention relates to improvements in sliding contact materials.
従来の摺動接点材料としては各種材料が用いられ、とり
わけ刷子接点材料としては、Ｐ ｄ ４０〜６０重量％
、Ａｇ４０〜６０重量％より成る合金材料が広く用いら
れていた。Various materials are used as conventional sliding contact materials, and in particular, as brush contact materials, P d is 40 to 60% by weight.
, alloy materials consisting of 40-60% by weight of Ag were widely used.
然し乍ら、この合金材料で製作した刷子接点では、摺動
時の耐摩耗性に劣っていた。However, brush contacts made of this alloy material had poor wear resistance during sliding.
本発明は、斯かる欠点を解消すべくなされたものであり
、前記合金材料を基材としてこれにＡｕを添加させて、
潤滑性を高め、耐凝着性を向上させた摺動接点材料を提
供せんとするものである。The present invention has been made to eliminate such drawbacks, and uses the above alloy material as a base material and adds Au to it.
The object of the present invention is to provide a sliding contact material with improved lubricity and adhesion resistance.
本発明の摺動接点材料は、Ｐ ｄ ４０〜６０重量％。The sliding contact material of the present invention has a Pd of 40 to 60% by weight.
Ａ ｇ ４０〜６０重量％より成る合金材料にその組成
比に変更を加えずに、Ａｕを３０〜５０重量％添加して
成るものである。It is made by adding 30 to 50% by weight of Au to an alloy material consisting of 40 to 60% by weight of Ag without changing its composition ratio.
本発明の摺動接点材料に於いて、Ｐ ｄ ４０〜６０重
量％、Ａｇ４０〜６０重量％より成る合金材料に、その
組成比に変更を加えずに、Ａｕを３０〜５０重量％添加
している理由は、前記合金材料の耐凝着性を向上すべく
潤滑剤を高める為で、３０重量％未満ではその効果を発
揮できず、５０重量％を超えると高価になるだけでそれ
以上の効果の得られないものである。In the sliding contact material of the present invention, 30 to 50 weight % of Au is added to an alloy material consisting of 40 to 60 weight % of Pd and 40 to 60 weight % of Ag without changing the composition ratio. The reason for this is to increase the amount of lubricant in order to improve the adhesion resistance of the alloy material, and if it is less than 30% by weight, it will not be effective, and if it exceeds 50% by weight, it will only be expensive and will not be more effective. It is something that cannot be obtained.
次に下記表の左欄に示す成分組成の本発明による摺動接
点材料と従来の摺動接点材料を用いて夫々線径Ｑ、７＋
＋ｍの刷子線材を作り、これを各々長さ８龍に切断し、
２本並列させて一端を幅１（ｈａ、長さ１３鰭、厚さ０
．２＋ｕの合材に溶接し、他端に２Ｒせ、整流子を正逆
回転させて下記の試験条件にて摺動試験を行い、摩耗量
及び接触批抗を測定した処、下記の表の右欄に示すよう
な結果を得た。Next, using the sliding contact material according to the present invention and the conventional sliding contact material having the compositions shown in the left column of the table below, wire diameters Q and 7+ were used, respectively.
+m brush wire rods were made, each of which was cut into lengths of 8 lengths,
Two fins are placed in parallel and one end has a width of 1 ha, a length of 13 fins, and a thickness of 0.
．． Welded to a 2+U composite material, put 2R on the other end, rotated the commutator in forward and reverse directions, and conducted a sliding test under the following test conditions, and measured the amount of wear and contact resistance. The results shown in the column were obtained.
試験条件
電 流 ：ｏ、ｅＡ
電圧： １２Ｖ
負 荷 ： 抵抗負荷
回転速度 ： １０００ｒ ｐ ｍ
周 速 ：１３０〜１２０ｍ ／ ｍ ｉ ｎ上記の表
で明らかなように実施例１〜３の刷子接点は従来例の刷
子接点に比し摩耗量が少なく、接触抵抗が同等に低く安
定していることが判る。Test conditions Current: o, eA Voltage: 12V Load: Resistance load Rotation speed: 1000rpm Peripheral speed: 130-120m/min As is clear from the table above, the brush contacts of Examples 1 to 3 were conventional It can be seen that the amount of wear is less than that of the brush contact in the example, and the contact resistance is equally low and stable.
これはひとえに実施例１〜３の刷子接点の刷子線材を構
成している本発明の摺動接点材料が、Ａｕの添加により
潤滑性が高められ、耐凝着性が向上するからに他ならな
い。This is simply because the sliding contact material of the present invention, which constitutes the brush wire of the brush contacts of Examples 1 to 3, has enhanced lubricity and improved adhesion resistance due to the addition of Au.
以上詳記した通り本発明による摺動接点材料によれば、
従来の摺動接点材料に比べ耐摩耗性に優れ、また従来の
摺動接点材料による場合と同等に低い接触抵抗を有する
刷子接点を得ることができるという効果がある。As detailed above, according to the sliding contact material according to the present invention,
The present invention has the advantage that it is possible to obtain a brush contact that has superior wear resistance compared to conventional sliding contact materials and has a contact resistance as low as that of conventional sliding contact materials.
