Abstract

L'invention concerne un mécanisme de transmission à mouvement alternatif (10), qui comprend un arbre de transmission (100), un manchon à mouvement alternatif (200) et des corps de limitation (300). Lorsque l'arbre de transmission tourne autour de son propre axe, les corps de limitation sont positionnés sur la paroi externe de l'arbre de transmission, et l'arbre de transmission pénètre le manchon à mouvement alternatif, de sorte que les corps de limitation pénètrent une rainure de mouvement alternatif (210). De plus, la rainure de mouvement alternatif est une rainure incurvée fermée autour de l'axe de l'arbre de transmission, et les crêtes d'onde et les creux d'onde de la rainure de mouvement alternatif sont disposés à des intervalles le long de l'axe de l'arbre de transmission, de sorte que, lorsque les corps de limitation tournent conjointement avec l'arbre de transmission, les corps de limitation coulissent entre les crêtes d'onde et les creux d'onde de la rainure de mouvement alternatif, ce qui permet d'atteindre l'objectif d'entraînement du manchon à mouvement alternatif pour effectuer un mouvement alternatif dans la direction axiale de l'arbre de transmission. Le mécanisme de transmission à mouvement alternatif ne comporte pas d'angle de déflexion, et il n'y a par conséquent pas de problème de travail par frottement de force de déviation ; et le mécanisme de transmission à mouvement alternatif a une structure simple et une large plage d'applications, et peut être appliqué à des cas, tels que des compresseurs et des structures de corps de pompe, qui nécessitent un mouvement alternatif. De plus, l'invention concerne en outre un appareil électrique comprenant le mécanisme de transmission à mouvement alternatif.
