The invention provides a linear stroke electric actuator with adjustable dead zone. The linear electric actuator with adjustable dead zone includes a mounting box, an executive assembly, a connecting assembly, a manual clutch, a driving assembly, a limit assembly, a braking assembly, a rotating assembly and a control assembly. The dead zone in the present invention can be adjusted according to the actual situation. By setting the brake assembly, when the linear stroke electric actuator is not driven to run, the brake block is controlled by the cylinder to descend and the tooth groove is blocked by the brake gear. The support shaft brakes, thereby braking the drive shaft, preventing the valve inside the valve from driving the drive shaft to rotate when it is subjected to greater resistance, improving the stability of the device and the service life of the device. The drive shaft can also be driven by a manual turntable, which is more flexible in use; each component in the device can be detachably connected to the installation box, which is convenient for maintenance and replacement of various components installed on the linear stroke electric actuator.
Description
technical field [0001] The invention relates to the field of electric actuators, in particular to a linear stroke electric actuator with adjustable dead zone. Background technique [0002] An electric actuator is an actuator, and the broadest definition of an actuator is; a drive device that can provide linear or rotary motion, which uses a certain driving energy and works under the action of a certain control signal. An actuator uses liquid, gas, electricity or other energy and converts it into drive action through a motor, cylinder or other device. In order to realize the mechanized operation of the existing valve, a straight-stroke electric actuator will be installed on the valve to realize the opening and closing control of the valve. [0003] After the existing straight-stroke electric actuator drives the valve, the valve inside the valve will drive the transmission parts inside the straight-stroke electric actuator to reverse when it is subjected to greater resistance...
