一、问题的提出 我国第一台8,000马力舰用自动同步离合器,已经进行了陆上单机试验。试验结果表明,该离合器的设计、试制基本上是成功的。但一致认为,尚需对下列几个问题进一步探讨和研究: 1.棘轮,棘爪耐冲击加速度的能力; 2.棘爪弹簧的疲劳寿命; 3.驱动齿的硬化处理与耐磨性的问题; First, the issue put forward China’s first 8,000 horsepower ship automatic synchronization clutch, has been carried out on land single test. The test results show that the clutch design, trial production is basically successful. However, it was agreed that the following issues still need to be further explored and studied: 1. The ability of ratchet and ratchet to resist impact acceleration; 2. The fatigue life of ratchet spring; 3. The problem of hardening and wear resistance of driving gear ;
