Small and exquisite type electric actuating mechanism adopting intelligent control

Abstract

The invention relates to the technical field of actuating mechanisms, in particular to small and exquisite type electric actuating mechanism adopting intelligent control. The small and exquisite type electric actuating mechanism adopting intelligent control comprises an installation plate and a motor. The small and exquisite type electric actuating mechanism adopting intelligent control is characterized in that the motor is connected with the upper end of the installation plate, an extension shaft of the motor is connected with a transmission gear, the transmission gear is in shaft joint with a shaft gear, the upper end of the shaft gear is connected with a shaft gear rack through a shaft sleeve, the portion, below the shaft gear rack, of the shaft gear is in shaft joint with a brake through a flat key, the outer edge of the brake is sleeved with a braking seat, and planet gears are arranged on the left and right sides below a plane gear and meshed with a center gear; an inner gear is in shaft connection to the portion, located below the planet gears, of a spline shaft and inner teeth of the inner gear are connected with the planet gears in meshed manner; and one side of the planet gears is connected with a worm through a tooth ring worm gear. Compared with the prior art, the small and exquisite type electric actuating mechanism adopting intelligent control is compact in structure, simple in shape, small in size, light in weight and good in stability and reliability.

Description

technical field [0001] The invention relates to the technical field of actuators, in particular to an intelligently controlled fine and small electric actuator. Background technique [0002] Electric actuators are increasingly used. While industries such as power plants, petrochemicals, and water conservancy facilities are increasingly emphasizing automated industrial control, electric actuators are increasingly being used in the above industries. At the same time, the use of electric actuators and the requirements for all aspects are further improved. Electric actuators are used in various key positions, and their reliability and flexible use also need to meet higher requirements. [0003] The electric actuator has the advantages of convenient access to energy, fast signal transmission speed, and long signal transmission distance to facilitate centralized operation and control, and it has high precision and relatively high sensitivity. [0004] In some environments with r...

Problems solved by technology

[0004] In some environments with relatively poor site conditions, electric actuators can reduce the labor intensity of personnel. Current electric actuators generally have two execution methods: electric and manual. When power failure or other failures occur during electric execution, through The electric-manual conversion mechanism realizes manual operation, but manual operation is required after the power is restored, switching manual execution to electric execution wastes time and efficiency, and the switching device has a complex structure
