NGC液压联轴器广泛用于船舶轴系之间联接,它采用液压的方式进行装拆,不需要热膨胀。安装时,两个配合面为锥面的厚外套和薄内套装配在一起,高压油被注入到此配合锥面,使配合面间形成油膜,再向活塞腔里注入低压油,推进外套在内套上移动,移动合适距离后,释放油压,外套收缩紧压在内套上,内套和轴之间建立起强大的压力;工作时,该压力将产生摩擦力,从而使液压联轴器具有强大的扭矩传递能力。
产品范围
■ 传递扭矩范围:26kNm~9052kNm;
■ 轴颈范围:100mm~700mm
NGC液压联轴器可以分为圆筒式液压联轴器(NHC)和法兰式液压联轴器(NHF)。圆筒式液压联轴器联接两个均不带法兰的轴;法兰式液压联轴器联接一个不带法兰和一个带法兰的轴。
性能特点:
■ 装拆简单方便;
■ 轴上不需要键槽和推力环;
■ 整个接触面受力较为均匀,应力集中不明显;
■ 轴系振动载荷变化时对轴不会造成磨损;
■ 联轴器在轴上的位置容易保证,连接精度高;
■ 可以重复使用,可换性高。
