Publication number: 20250019093Abstract: The present invention discloses an SMA wire-driven reusable release mechanism having a self-resetting function. The present invention adopts a structure of two-stage load reduction and one-stage release. First-stage load reduction: a compression rod and a hoop petal, as well as an inclined block and a shell or a sliding block, all cooperate with each other by means of inclined surfaces, which can transfer most of tension load of the compression rod to the shell, leaving only a small part of the load transmitted to a thrust bearing. Second-state load reduction: balls in the thrust bearing are coated with a molybdenum disulfide lubricating coating, which can effectively reduce friction so as to reduce a torque transmitted to a driving shaft. First-stage release: the driving shaft drives a thrust bearing to rotate by a certain angle, causing an upper ring of the thrust bearing to descend to release a certain axial clearance.Type: ApplicationFiled: October 1, 2024Publication date: January 16, 2025Applicant: Beijing University Of Aeronautics And AstronauticsInventors: Xiaojun YAN, Jiaming LENG, Lei QU, Xiaoyuan WANG, Zhiwei LIU, Weifeng WAN, Huimin LI
