Abstract

The invention belongs to the technical field of electric valve actuators, and in particular, relates to a pneumatic jaw clutch. The pneumatic jaw clutch comprises a left half clutching part and a right half clutching part; the left half clutching part comprises a left half clutch, a rotating shaft, a double-row angular contact ball bearing, a locking nut, a brake gasket, a spring base and a piston; the right half clutching part comprises a right half clutch, a cylinder and an output shaft; the left half clutching part and the right half clutching part are connected through end surface teeth; the end surface teeth adopt a design of self-locking structures; and a pretightening spring is arranged between the left half clutching part and the right half clutching part. The pneumatic jaw clutchachieves a coupling effect to transfer an output torque in normal work, and uses a final energy air source for driving the clutch to open a valve to achieve an emergency function in emergent work.

Description

technical field [0001] The invention belongs to the technical field of electric valve actuators, and in particular relates to a jaw-type pneumatic clutch. Background technique [0002] For ship systems, reliability is undoubtedly the first. The jaw-type pneumatic clutch, as the emergency equipment of the electric valve actuator, is of great significance to improving the safety of the personnel in the boat and the reliability of the equipment. [0003] At present, the valve opening and closing of a ship is controlled by a hydraulic cylinder, which has a complex structure and poor maintainability. For this reason, electric valve actuators are used to replace hydraulic cylinders to control valve opening and closing. In order to improve the reliability of the electric valve actuator, so that it can ensure the normal opening of the controlled valve even in the case of power failure, it is necessary to develop an emergency equipment that can use the last energy source on the shi...
