Problems solved by technology

1. If the elastic baffle plate of the fixed potentiometer is continuously adjusted several times, the toughness of the elastic plate will be weakened, causing the gear of the potentiometer to fail to return to the initial position, and it is easy to lose the teeth when meshing with the feedback large gear
2. When the axial swing of the feedback gear is large, it is easy to make the feedback gear of the potentiometer and the large feedback gear lose their teeth
3. It is inconvenient to debug the feedback resistance of the potentiometer

Embodiment Construction

[0009] like figure 2 As shown, the present invention provides a feedback device for an electric actuator, which includes a meshed feedback gear 4 and a feedback potentiometer gear 7, and the feedback potentiometer gear 7 is sleeved on the feedback potentiometer shaft 5. On the feedback potentiometer shaft 5 below the potentiometer gear 7, a hex nut 2 and a feedback potentiometer 8 are sequentially set, and a feedback potentiometer slider 6 is also installed between the hex nut 2 and the feedback potentiometer 8. The potentiometer slide block 6 and the feedback potentiometer 8 are installed on the track of a feedback component fixing frame 1, and also include an elastic element 3, one end of the elastic element 3 is fixed on the feedback component fixing frame 1 and the other end is fixed On the slider 6 of the aforementioned feedback potentiometer.

[0010] Wherein the feedback potentiometer 8 is fixedly installed on the slider 6 of the feedback potentiometer.

Abstract

The invention relates to a feedback device for an electric actuating mechanism. The feedback device is characterized in that a feedback potentiometer slide block (6) is installed between a hexagon nut (2) and a feedback potentiometer (8), the feedback potentiometer slide block (6) and the feedback potentiometer (8) are installed on a track of a feedback part fixing mount (1), the feedback device also comprises an elastic element (3), one end of the elastic element (3) is fixed to the feedback part fixing mount (1), and the other end of the elastic element (3) is fixed to the feedback potentiometer slide block (6). The feedback device for an electric actuating mechanism is simple and fast, can effectively improve reliability of engagement of a potentiometer feedback gear and a feedback bull gear, and prevents feedback shaft axial-direction swinging-caused disengaging of teeth of the feedback bull gear and the potentiometer feedback gear.

Description

technical field [0001] The invention relates to a feedback device for an electric actuator. Background technique [0002] like figure 1 As shown, the current common potentiometer is fixed by an elastic plate, and the meshing distance between the feedback gear of the potentiometer and the large feedback gear is adjusted through the toughness of the elastic plate. However, the adjustment of the meshing distance between the feedback gear of the potentiometer and the large feedback gear through the toughness of the elastic plate has the following defects. 1. If the elastic baffle plate of the fixed potentiometer is continuously adjusted several times, the toughness of the elastic plate will be weakened, causing the gear of the potentiometer to fail to return to the initial position, and it is easy to lose teeth when meshing with the large feedback gear. 2. When the axial swing of the feedback gear is large, it is easy to make the potentiometer feedback gear and the large feedb...
