working principle:
扭矩限制器又叫扭力联轴器、联轴器。根据结构主要分为摩擦式扭力限制器、滚珠式扭力限制器。
Torque limiter is also called torque coupling and safety coupling. According to the structure, it is mainly divided into friction type torque limiter and ball type torque limiter.
摩擦型扭力限制器是利用锁紧螺母来使弹簧产生弹力，作用于摩擦片上， 链轮等轮状物体被夹在两片摩擦片之间，由于弹力的作用使得摩擦片和链轮间产生摩擦力，从而能进行传送扭矩。
The friction type torque limiter uses the lock nut to make the spring generate elastic force and act on the friction plate. The wheel like objects such as the sprocket are sandwiched between the two friction plates. Due to the elastic force, the friction force is generated between the friction plate and the sprocket, so that the torque can be transmitted.
设备发生过载时，链轮和摩擦片之间产生相对滑动， 但是两者之间依然保持着打滑时的扭矩此时主动端空转，使传动端停掉。
When the equipment is overloaded, there is relative sliding between the sprocket and the friction plate, but the torque during slipping is still maintained between them. At this time, the driving end idles and stops the driving end.
采用精密弹簧控制临界扭矩，达到非常精准的扭矩值,同一外形尺寸产品，可以更换不同的内置弹簧来确定不同的打滑扭矩,用于一边是轴，一边是传动的安装,也可根据客户要求配备联轴器，以方便客户进行轴对轴链接。
The critical torque is controlled by precision springs to achieve a very precise torque value. For products with the same overall size, different built-in springs can be replaced to determine different slip torques. It is used for the installation of shaft and transmission on one side. It can also be equipped with couplings according to customer requirements to facilitate the customer's shaft to shaft connection.
扭矩限制器
Torque limiter
扭矩限制器，也称扭力限制器，是联接主动机与工作机的一种部件，主要过了载保护，扭力限制器是当超载或机械故障而导致所需扭矩超过设定值时，扭矩限制器以打滑形式限制传动系统所传动的扭力；
Torque limiter, also known as torque limiter, is a component connecting the driving machine and the working machine. It is mainly used for overload protection. When the required torque exceeds the set value due to overload or mechanical failure, the torque limiter limits the torque transmitted by the transmission system in the form of slip;
打滑的同时也能一个信号输出停掉电机和减速机，当过载情形消失后自行恢复联结。这样就可以防止了机械损坏，从而避免了昂贵的停机损失。
At the same time, it can also output a signal to stop the motor and reducer. When the overload situation disappears, it will automatically restore the connection. In this way, mechanical damage can be prevented, thereby avoiding expensive shutdown losses.
