The paper presents a new constructive and functional solution of flexible coupling with bolts and nonmetallic intermediary elements. The bolts have a special shape in the sense that they have a milled area on a certain length equal to the width of the non-metallic element, a cylindrical area that reduces the stress concentrators at the diameter passages. The novelty of this coupling consists of the existence of one intermediary disk between two semi couplings (driver and driven semi couplings). This is fixed by the semi-coupling on the right side, the intermediary disc having milled four locations in which to mount the left, as the right has a metal plate with a special shape of eight metallic plates that are mounted with screws in the four milled places processed on the intermediate disc. The nonmetallic elements have various forms and can be made from different qualities of rubber mounted on the bolts. Eight milled bolts (four on each semi-coupling) allow the transmission of the torsion moment in both directions of rotation, in one direction becoming rigid and thus behaving like a safety coupling. Finite element method is used to obtain the mechanical response of this new type of coupling.

机械传动中使用螺栓的柔性联轴器的新的优化解决方案

本文提出了一种新的构造性和功能性解决方案，即螺栓和非金属中间元件的挠性联轴器。从一定意义上讲，螺栓具有特殊的形状，即在一定长度上具有等于非金属元件宽度的铣削区域，该圆柱区域减小了直径通道处的应力集中器。这种联轴器的新颖性在于两个半联轴器（驱动器和从动半联轴器）之间存在一个中间盘。这是通过右侧的半联轴器固定的，中间圆盘在铣削后的四个位置上安装左侧，因为右侧有一个特殊形状的金属板，八个金属板用螺钉固定在四个中在中间圆盘上加工的铣削位置。非金属元件具有各种形式，并且可以由安装在螺栓上的不同质量的橡胶制成。八个研磨螺栓（每个半联轴器上四个）允许扭力在两个旋转方向上传递，在一个方向上变硬，因此就像安全联轴器一样。有限元方法用于获得这种新型联轴器的机械响应。
