Torque limiters / overload couplings

What are mechanical safety 联轴器 used for? The mechanical safety 联轴器 is also referred to as 扭矩 limiter or overload 联轴器. In 传动技术, this refers to a machine element limiting the 扭矩 in the drive train to a maximum figure or fully interrupting the 扭矩 flow in case of downtime of the machine. That way 过载联轴器 are able to protect machine 元件 against damages, e. g. collisions by programming or operating errors.
