GY、GYS、GYH型联轴器主要有夹壳联轴器和凸缘联轴器两种,结构简单,使用方便,可传递大的扭矩,但不能缓冲减震。

A detailed description

GY、GYS、GYH型联轴器属于刚性联轴器,是把两个带有凸缘的半联轴器用普通平键分别与两轴连接,然后用螺栓把两个半联轴器连成一体,以传递运动和转矩。

这种联轴器有两 种主要的结构形式:

①Relying on reamed holes and bolts to realize the two-axis centering and relying on the bolt rod to bear extrusion and shear to transmit torque;

②靠一个半联轴器上的凸肩与另一个半联轴器上的凹槽相配合而对中。连接两个半联轴器的螺栓可以采用   和B级的普通螺栓,转矩靠两个半联轴器结合面的摩擦力矩来传递。

GY、GYS、GYH型联轴器的材料可用灰铸铁或碳钢,重载时或圆周速度大于30米/秒时应用铸钢或锻钢。凸缘联轴器对两轴对中性的要求很高,当两轴有相对位移存在时,就会在机件内引起附加载荷,使工作情况恶化,这是它的主要缺点。但由于结构简单、成本低、可传递较大转矩,故当转速低、无冲击、轴的刚性大、对中性较好时常采用。
