我厂滚子车间使用的Z31—25型滚子自动冷镦机送料系统是采用异形滚子支柱离合器来完成周期性间断送料工作的。在使用过程中,发现此种异形滚子离合器有如下两大缺点:1.由于离合器所采用的异形滚子数量多,形状复杂,加工备件困难,维修装配均不方便;2.各异形滚子之间是用一根细长的拉簧联接,因而弹簧易断,经常造成工作失灵。 Z31-25 roller automatic cold heading machine feeding system used by our factory roller workshop is the use of special-shaped roller prop clutch to complete the cyclical intermittent feeding work. In the process of using, it is found that such a profiled roller clutch has the following two disadvantages: 1. As the number of special-shaped rollers used in the clutch is large and the shape is complex, spare parts are difficult to process and maintenance and assembly are inconvenient; 2. The profiled rollers Between the use of a slender tension spring connection, so the spring is easy to break, often resulting in work failure.
