转键式刚性离合器,由于其结构简单紧凑、制造维修方便,在小型压力机上仍然广泛采用,特别是我国已生产的100T以下的开式压力机上采用此离合器更为普遍。转键式刚性离合器一般与带式制动器配合使用,由于某些资料对刚性离合器和带式制动器是分开介绍的,最后又合起来计算,而造成在计算上的脱节和不符合实际的情况,致使在使用过程中经常发生带式制动器的钢带断裂和转键的键柄断裂等现象,从而人们习惯地认为制动钢带和转键均为易损件。在使用过程中,由于键柄经常断裂而造成压力机连冲,有时会发生人身事
Because of its simple and compact structure, easy maintenance, it is still widely used in small presses, especially the open presses below 100T produced in China. Rigid key clutches are generally used in conjunction with band brakes. Since some of the information is presented separately for rigid clutches and band brakes and finally calculated together, resulting in computational disjointment and unrealistic conditions, In the process of using the belt brake often break the key and the key to break the key switch and other phenomena, so people customarily think that both the brake steel and transfer keys are wearing parts. In use, due to frequent rupture of the key handle caused by the press Lian Chong, and sometimes personal things happen
