Description
【発明の詳細な説明】 可撓駆動カップリング 本発明は、駆動ハブと被駆動ハブを有し、これらのハブがそれぞれ１つの板ばね 要素に取付けられ、これら板ばね要素が直径方向に対向する箇所で上記のハブか らある半径方向の距離をもって相互に連結されている、可撓駆動カップリングに 関するものである。[Detailed description of the invention] flexible drive coupling The invention has a driving hub and a driven hub, each of which has a leaf spring. attached to the hub at the point where these leaf spring elements are diametrically opposed. flexible drive couplings interconnected at a radial distance from each other; It is related to
この型の可撓駆動カップリングはハブ間の相対角度変位があまり大きくない時は ユニバーサルジヨイントに代えて用いることができ、ユニバーサルジヨイントに 比べて、出力回転速度が角度変位と無関係でありそのため入力回転速度に等しい という利点をもたらすものである。さらに、この可撓駆動カップリングは相互に 摺動運動をするため取付けられた要素を有せず、そのためカンプリングが保守か ら解放され製作費が安くなる。This type of flexible drive coupling can be used when the relative angular displacement between the hubs is not very large. Can be used in place of a universal joint, and can be used in place of a universal joint. In comparison, the output rotational speed is independent of the angular displacement and is therefore equal to the input rotational speed. This brings about the advantage of Furthermore, this flexible drive coupling is mutually It does not have elements attached to it for sliding movement, which makes the camp ring less maintenance-friendly. This frees up production costs and reduces production costs.
可撓駆動カップリングは数種の異なった具体例が知られている。これらのカップ リングの全てが遭遇する１つの問題は板ばね要素がカンプリングの作動している 時に疲労を来たしそのため特に大きな角度変位の場合にその寿命がかなり短かく なるということである。本発明の目的はこの点に関してカップリングを改良する ことであり、またこの目的のため、本発明によって得られた上記のような種類の カップリングは、請求の範囲第１項から明らかな特徴を有している。Several different embodiments of flexible drive couplings are known. these cups One problem that all of the rings encounter is when the leaf spring element is activated in the camp ring. They sometimes get fatigued and therefore their lifespan is quite short, especially in the case of large angular displacements. It means that it will become. The object of the invention is to improve the coupling in this respect. and for this purpose, the above-mentioned kind obtained by the present invention. The coupling has the features that are clear from claim 1.
本発明を′さらに詳細に説明するため、本発明の１つの実施態様が添付図面を参 照して以下に説明される。To explain the invention in further detail, one embodiment of the invention is illustrated in the accompanying drawings. This will be explained below with reference to the following.
第１図ｔよ本発明の可撓駆動カップリングの端面図、第２図は第１図のカップリ ングの部分的に軸方向に切断した側面図、 第３図は第１図の■−■線に沿う拡大詳細断面図、第４図は変形実施態様の第３ 図と同様な波数詳細断面図である。FIG. 1 is an end view of the flexible drive coupling of the present invention, and FIG. 2 is an end view of the flexible drive coupling of the present invention. a partially axially sectioned side view of the FIG. 3 is an enlarged detailed sectional view taken along the line ■-■ in FIG. 1, and FIG. It is a detailed wave number cross-sectional view similar to the figure.
図において２つのハブ１０と１１・とが示されており、これうのハブの一方は駆 動用でありしたがって駆動シャフトに取付けられ、また他方は被駆動用でありし たがって被駆動シャフトに取付けられる。これらのハブはそれぞれ１つの板ばね 要素１２と１３に連結され、この板ばね要素は正方形を形成するがまたひし形と することもでき、ウェブ１４と１５がそれぞれ正方形又はひし形中に設けられこ の正方形又はひし形の２つの対向する隅部の間に延在しこれに取付けられた結合 ハブを存している。他の２つの対向する隅部において２つの板ばね要素はリベッ ト１６により相互に連結されるが、この連結はボルト又はねじ接合により又は溶 接もしくはろう付けでも得られる。これらの板ばね要素は、ハブめ端部が相互に 間隔をおき、そしてこれらハブが実質的に相互に同軸上に配置された図示の状態 からカップリングが多少の角度変位ができるように形成されている。Two hubs 10 and 11 are shown in the figure, one of which is the driving hub. one for driving and therefore mounted on the drive shaft, the other for driven It is therefore attached to the driven shaft. Each of these hubs has one leaf spring Connected to elements 12 and 13, this leaf spring element forms a square but also a rhombus. The webs 14 and 15 can also be provided in a square or diamond shape, respectively. a bond extending between and attached to two opposite corners of a square or diamond shape There is a hub. At the other two opposite corners the two leaf spring elements are riveted. 16, which connections may be made by bolts or screw connections or by welding. It can also be obtained by welding or brazing. These leaf spring elements have hub female ends that touch each other. as shown with the hubs spaced apart and substantially coaxial with each other. The coupling is formed to allow some angular displacement.
カップリングが角度的に変位した状態で作動している時、板ばね要素はこれらの ハブが取付けられた箇所と板ばね要素が相互に連結された箇所とで一方の方向と 他方の方向とに交互に連続した曲げ作用を受けることになる。この曲げ作用と結 びつく板ばねの応力を減少させるため、ハブと板ばね要素との間の連結について 図示のような方法で取付は具が配設される。When the coupling is operating with angular displacement, the leaf spring elements in one direction and at the point where the hub is attached and where the leaf spring elements are interconnected. It is subjected to continuous bending action alternately in the other direction. This bending action and For the connection between the hub and the leaf spring element to reduce stress in the stiff leaf spring. Mounting tools are provided in the manner shown.
各板ばね要素１２と１３の両面に、２つの支持板ばね（又は支持板）１７と１８ が設けられ、これらの支持板ばねは板ばね要素の対向側面に係合し、同じ長さ又 は図示のように異なる長さとすることができる。これら２つの支持板ばねは板ば ね要素よりも堅くなければならず、それにより支持板ばねの外側自由端部で板ば ね要素のための保合箇所を形成するようにしている。この端部で支持板ばねは好 ましくは板ばね要素に面している側でわん曲され、そしてこの丸みは第３図に示 すように支持板ばねの自由端を外側に向けて曲げることにより得られる。On both sides of each leaf spring element 12 and 13 there are two support leaf springs (or support plates) 17 and 18. are provided and these support leaf springs engage opposite sides of the leaf spring elements and have the same length or can have different lengths as shown. These two support leaf springs are It must be stiffer than the spring element, so that the outer free end of the support leaf spring This is to form a retaining point for the element. At this end the support leaf spring is Preferably, it is curved on the side facing the leaf spring element, and this rounding is shown in Figure 3. This is obtained by bending the free ends of the support leaf springs outwards so that the
好適な実施態様においては、図示の例に示すように、支持板ばねは異なった長さ を有し、それにより板ばね要素が一方の側と他方の側とに交互に曲げられた時支 持板ばねが異なった箇所で係合するようにする。この構造により、係合箇所にお いて板ばね要素の同一の箇所での交互の応力はなく、２つの相互に間隔のあけら れた箇所で変動する応力が得られることになり、このことは板ばね要素の寿命が 実質的に延長されることを意味する。In a preferred embodiment, the support leaf springs are of different lengths, as shown in the illustrated example. , whereby the leaf spring element is bent alternately to one side and to the other. The retaining plate springs are made to engage at different points. This structure allows the There is no alternating stress at the same location of the leaf spring element, but two mutually spaced This results in a varying stress at the location where the leaf spring element is This means that it will be substantially extended.
この実施態様はさらに少なくとも１つのそして好ましくは第４図に示す方法でよ り長い支持板ばね１７を形成することにより改良される。板ばね要素１２に面す る側において支持板ばね１７の外側自由端部の１９でフライス削りすることによ り材料が支持板ばね１７から取除かれ、それによりこの支持板ばねは、板ばね要 素が角度変位して最初に係合するフライス削りされた部分の内側端部の一方の箇 所と支持板ばねの自由端の他方の保合箇所との２つの半径方向に間隔をおいた係 合箇所を形成する。このフライス削りされた部分の深さは１ｍＩＩの何分の１よ り多くは必要とせず、そしてその長さはこのフライス削りされた部分が支持板ば ねの外側自由端部の下側に延在するような大きさとしなければならない。支持板 ばね１７と１８との間に３ｍｌの長さの差を有する１つの実施態様において、５ 關の長さとＯ，） ＊ｍの深さとを有するフライス削りされた部分は板ばね要素 １２の寿命を著しく延長できることがわかった。この寿命は、同じ長さを有しか つフライス削りされた部分を有しない実施態様よりも７０倍から１００倍のオー ダーである。This embodiment further includes at least one and preferably the method shown in FIG. This is improved by forming the support leaf spring 17 with a longer length. facing the leaf spring element 12 by milling 19 of the outer free end of the support leaf spring 17 on the material is removed from the support leaf spring 17, so that this support leaf spring One point on the inside edge of the milled part where the element is angularly displaced and engages first. two radially spaced engagements between the point and the other retaining point of the free end of the support leaf spring. form a joint. The depth of this milled part is a fraction of 1 mII. This milled part does not require much, and its length is The dimensions shall be such that they extend below the outer free ends of the springs. support plate In one embodiment with a 3 ml length difference between springs 17 and 18, 5 The milled part with the length of the lock and the depth of O, ) * m is a leaf spring element. It has been found that the lifespan of 12 can be significantly extended. Does this lifespan have the same length? 70 to 100 times more efficiency than embodiments without milled parts It is.
