    • A lightweight spring type torque limiter is proposed, which performs the torque limiting function using the binding force applied from a coil spring to an inner ring inserted in an outer annular member. The inner ring (2) is rotatably inserted in the outer annular member (1). The coil spring (3) is fitted around the inner ring (2) and includes a small-diameter portion (3a) tightened against the radially outer surface of the inner ring (2). The coil spring (3) has hooks (3c and 3d) at the respective ends thereof which are coupled to the outer annular member (1) and an adjusting ring (4) rotatably fitted in the outer annular member (1), respectively. The inner ring (2) is formed by injection-molding a thermoplastic resin to reduce the weight of the inner ring and thus the weight of the entire torque limiter, compared to conventional inner rings, which are made of metal, and conventional torque limiters including an inner ring made of metal.
    • 提出了一种轻型弹簧式扭矩限制器,其使用从螺旋弹簧施加到插入外环形构件的内环的绑定力来执行扭矩限制功能。 内圈(2)可旋转地插入外环形构件(1)中。 螺旋弹簧(3)围绕内圈(2)安装,并且包括紧靠内圈(2)的径向外表面的小直径部分(3a)。 螺旋弹簧3在其各自的端部具有联接到外环形构件(1)的钩(3c和3d)和分别可旋转地装配在外环形构件(1)中的调节环(4)。 通过注射成型热塑性树脂来形成内圈(2),与通过金属制的常规内圈相比,通过注射成型热塑性树脂来减小内圈的重量,从而与整个扭矩限制器的重量,以及传统的扭矩限制器 由金属制成的内圈。
