Embodiment Construction
[0022] In addition to the embodiments described below, the present invention may also have other embodiments or be practiced in different ways. Therefore, it should be understood that the invention is not limited to the details of construction of the components described in the following specification or illustrated in the accompanying drawings. While only one embodiment is described herein, the claims are not limited to that embodiment.
[0023] The present invention is a split type anti-rolling type double degree of freedom lug, such as figure 1 , figure 2 , image 3 As shown, it includes a single support lug 1, a limit anti-rotation block 7, a positioning pin 8, a fastening screw 9 and a spring washer 10; the limit anti-rotation block 7 and the single support lug 1 are positioned through the positioning pin 8, and successively Install the spring washer 10 and the fastening screw 9 to fasten the connection;
[0024] The double-degree-of-freedom support lug also includes...

A split type anti-rolling type double-freedom-degree lug comprises a single lug body, a positioning pin, fastening screws, spring washers and a limiting anti-rotation block; the limiting anti-rotationblock and the single lug body are positioned through the positioning pin, and the spring washers and the fastening screws are installed in sequence for fastening and connection. According to the lug,the structural rigidity is improved, and meanwhile, the gap is reduced, so that the overall rigidity of an electromechanical actuator is improved, and the dynamic performance of the actuator is improved; the total weight of an upper lug body and an upper lug bracket can be greatly reduced; meanwhile, the manufacturing and assembling processes are simplified.
Description
technical field [0001] The invention belongs to the field of electromechanical servo systems, and in particular relates to a split type anti-roll type double-degree-of-freedom support lug. Background technique [0002] For electromechanical actuators, the common single lug assembly has a simple structure and high reliability, but cannot limit the degree of freedom of its rolling around the axis. When the motor is in operation, its own rotation will cause the entire electromechanical actuator to roll coaxially in the opposite direction, and this rolling will affect the dynamic and static characteristics of the electromechanical actuator. The solution usually adopted at present is the cross-shaft structure, which overcomes the problem of rolling between the upper and lower lugs of the electromechanical actuator, but the cross-shaft structure is more complicated, the space and weight are increased, and the increase Larger clearance. [0003] To this end, the present invention...
