H PJ76A双37mm舰炮高低机蜗杆副在舰炮失控高速冲击下限位时容易卡死,造成火炮瘫痪,影响部队正常使用。拟采用平面二次包络蜗轮蜗杆传动副替代原阿基米德圆柱蜗杆传动副,彻底解决此问题。
H PJ76A double 37mm naval gun high and low machine worm in the high-speed impact of naval gun can easily be stuck under the limit, resulting in the paralysis of artillery, affecting the normal use of troops. It is proposed to use a planar secondary enveloping worm gear instead of the original Archimedes cylindrical worm gear pair to completely solve this problem.
