A guide vibration isolator structure consists of a rotor, a stator, an elastic element, a floating plate, threaded pins and a rolling component. The rotor is provided with a flat panel which is perpendicular to the axis and contacts with the elastic element, the stator is a supporter of the elastic element and is fixedly connected with the elastic element, and the floating plate is connected with the rolling component through the threaded pins arranged symmetrically. When the guide vibration isolator structure is provided with the single elastic element, the floating plate is fixed to the middle of the elastic element axially and perpendicular to the axis. When the guide vibration isolator structure is provided with two identical elastic elements, the floating plate is fixed between the two elastic elements and perpendicular to the axis. During working, a vibration isolated part is connected with the rotor through screws, the rotor moves relative to the stator by the aid of the elastic elements, the floating plate and the rolling component, and the stator is fixed on a vibrating platform through screws. The guide vibration isolator structure is suitable for photoelectric equipment or radar equipment with mobile platform and is an integrated design of vibration isolation and guiding. In addition, a guiding cross gap of the guide vibration isolator structure is controllable, and even no-gap design can be realized.
Description
technical field [0001] The invention relates to a guide vibration isolator structure, which is suitable for the vibration reduction system of the photoelectric equipment or radar equipment of the moving platform. Background technique [0002] In order to ensure that the photoelectric tracking and measuring equipment can work safely and reliably during transportation, the vibration-absorbing system without angular displacement is generally used in many cases. In experiments and practical applications, it is found that the non-angular displacement vibration reduction system mainly adopts a parallelogram structure and a linear guide rod structure. Due to the difficulty of eliminating the fit gap, it is difficult for the non-angular displacement vibration reduction system to achieve true angular displacement, and With the improvement of requirements, its processing and manufacturing are very difficult. Therefore, it is of great significance for practical application to design a...
