FALK蛇形彈簧聯(lián)軸器是利用分為一組或幾組的蛇形彈簧，嵌在兩半聯(lián)軸器凸緣上的齒間內(nèi)，以實現(xiàn)兩半聯(lián)軸器聯(lián)接，為防止蛇形彈簧在離心力作用下甩出及避免蛇形彈簧與齒接觸處發(fā)生干摩擦，需用封閉的殼體罩住，并在里面注以潤滑油或潤滑脂。蛇形彈簧聯(lián)軸器分為恒剛度和變剛度兩種，主要取決于彈簧接觸齒的下列兩種形式：齒形為直線形：在正常負載時，蛇形彈簧與齒接觸點之間的距離不隨蛇形彈簧變形量的改變而變化，剛度不變，兩半聯(lián)軸器的相對轉(zhuǎn)角與所傳遞的轉(zhuǎn)矩為線性關(guān)系，屬于恒剛度蛇形彈簧聯(lián)軸器。
