Abstract

The invention proposes a large-scale variable-speed adjustment mechanism with an electric actuator, and the mechanism comprises the electric actuator, a cam, and a driven wheel, wherein the electric actuator, the cam and the driven wheel are connected sequentially. The driven wheel is connected with a push rod through a pin shaft, and the push rod is disposed on a sliding rail. According to the invention, a variable speed movement device and an equal-speed movement electric actuation mechanism are integrated into a body, thereby achieving different moving speeds at some stages of a whole travel, and achieving the variable-speed adjustment, wherein the adjustment speed change is greater than 5-10 times.

Description

Technical field [0001] The invention belongs to the technical field of actuators, and in particular relates to an electric actuator capable of large-scale variable speed adjustment. Background technique [0002] In order to meet some special technological requirements in the industrial automatic control process, electric actuators will be required to achieve different response speeds within a certain range of travel, and the adjustment speed changes more than 5 to 10 times. The functions of the existing electric actuators implement variable-speed adjustment through frequency conversion technology, but they cannot achieve such a large-scale adjustment. Summary of the invention [0003] In view of this, the present invention provides an electric actuator with a large-scale variable speed adjustment to solve the limitation of the electric actuator with large-scale variable speed adjustment. [0004] The technical scheme of the present invention is realized as follows: [0005] A large-...
