Friction type torque limiter:


After the overload is eliminated, the friction torque limiter will reset automatically without any operation.


Ball torque limiter:


1.360 single point reset: for example, the disengagement point is 0 °,but after the limiter is overloaded, the inner ball slides out of the ball groove and stops at the 45 ° position. At this time, the torque limiter is disengaged at the 45 ° position. If you need to reset, you must turn the 45 ° position to the 0 ° point. You can turn 315 ° forward or reverse 45 ° to the 0 ° position. This operation can manually turn the torque limiter flange to reset or start the motor. It can reset automatically no matter whether it is rotating forward or reverse.


2. Multipoint reset: as the name suggests, multipoint reset means that there are multiple reset points in a circle, which can be required to be 15 degrees, 20 degrees, 30 degrees, 60 degrees, 90 degrees, 180 degrees, and so on. If it is 15 degrees reset, there are 24 reset points in a circle of torque limiter, and so on. This structure is suitable for the use of cam splitter and other similar conditions that need more reset.


3. Manual reset: once the manual reset torque limiter is in a state of complete disconnection after overload, there is no residual torque value between the active end and the transmission end at this time. The reset method must wait until the machine stops, and then manually use hammers and other tools to knock the active ring of the torque limiter to reset it. It is suitable for the environment of high inertia or cutting off the active end and the passive end immediately after overload Use.
