[求助]UL987 Section 27
标准里关于锯片的回转方向有下面的要求，但我有个疑问，锯片上法兰的拧紧方向和锯片的回转方向应当是相同的还是相反的？27 Rotating Members
27.1 A tool employing a user-removable rotating part, such as a blade or a grinding wheel, shall be
constructed so that the direction of rotation tends to tighten the nut that secures the rotating part in place. 应该是拧紧方向和运动部件旋转的方向相反，这样在运动部件旋转的时候螺母不会脱落！
