Failure mode analysis of clutch brake of precision high speed punch

    The clutch brake plays an important role in transmitting torque in the transmission system of precision high-speed punch. Even under the coordination and assistance of hydraulic, lubrication and air pressure systems, strong friction will still lead to overheating and wear of friction parts, and any factor leading to the decrease of clutch sensitivity and abnormal working state will directly cause problems in the operation of the transmission system, Work failure or even accident occurs.

Through the fault investigation of the clutch brake of high-speed punch and the previous fault tree analysis, the fault categories are obtained, and the four common fault forms of fault overheating, excessive braking angle, equipment slip and working noise are determined. The equipment slip is divided into two working states: machine tool clutch and machine tool braking, and the working noise is divided into two states: machine tool idling and transmission clutch.
