    EMB DS-ring characteristics and effects

    The EMB DS ring is the result of a consequent development of the well-known EMB cutting ring and is distinguished by the following characteristies.

    Because of the constructive design of the cutting geometry, the edges do not cut simultaneously, but one after the other, although the cutting diameters are exactly the same. Thereby an improved cutting effect is achieved as well as much greater steadiness during excision at the end of the installation with only slightly more effort 1.

    The DS ring has a limited surface that signals the end of the installation owing to its location

    within the body cone. And thereby a force increase is perceptible 2.

    As both cuttings, as well as the central section, have a supporting effect within the cone, the force is widely diffused there and thereby ensures a secure holding function 3.

    A rising strength is imparted to the whole length of the ring and flows over the ring on to the body cone and the cone of the nut. This effect arises from the conical design of the inside end 4.

    The conical surface opposite the cutting edges is highly finished, thereby reducing the loss by

    friction during the installation and resulting in a stronger grip. Besides higher stability, the reinforced end of the DS ring reduces friction and takes the pressure off the base of the nut.

    The required reduction of the cross-section optimizes the radial stability and thereby keeps the tube secure5. The stop area clearly limits overwinding by the bearing at the stud’s front

    EMB卡套特點及其作用

    EMB DS卡套是眾所周知的EMB卡套發展的結果,并因為以下特點脫穎而出:

    通過對其結構的優化設計,雖然切入直徑是完全一樣的,但是刃口并不是同時而是先后切入。

    由此只需在安裝結束前稍微多付出一些努力,即實現可達到改善的切入效果以及更大穩定性。

    1,DS卡套位于接頭體錐度的表面有限,因而可以通過應力的上升而傳遞安裝結束的信號;

    2,由于雙刃卡套包括中截面,在錐面上都具有支撐的作用,力在此處廣泛的分散取得了穩定的支撐作用;

    3,向上的應力被傳遞到整個卡套的長度上,并且通過卡套傳遞到接頭體內錐,以及螺母的錐面上,這是由于內部尾端的錐形設計;

    4,卡套刃口背面的錐形表面高度拋光處理,降低了安裝過程中的摩擦損失,使抓緊力更強。除了更好的穩定性外,DS卡套增強的尾部降低了摩擦,并且吧壓力從螺母基座上轉移,橫截面的減少,優化了徑向的穩定性,從而保護管子安全;

    5,接頭前端表面的軸承很明顯的限制了過渡扭曲;

    6、使密封性更強。
