Abstract[English]
A helical anti-backlash sleeve (1), a power assembly (2), and a solar device. The helical anti-backlash sleeve comprises a first sleeve (11) and a second sleeve (12), and a first helix (111) is provided on the outer peripheral surface of the first sleeve; the second sleeve and the first sleeve are coaxially arranged, a second helix (121) is provided on the outer peripheral surface of the second sleeve, and the pitch of the first helix is equal to the pitch of the second helix; the helical anti-backlash sleeve further comprises an elastic member (13), a connecting portion (16) and at least one limiting member (14), wherein the limiting member is used for limiting the maximum distance between the first sleeve and the second sleeve; the elastic member is used for adjusting the distance between the first sleeve and the second sleeve; and the connecting portion is used for connecting to an external driving member. The power assembly comprises the helical anti-backlash sleeve, a driving member, a shaft (22), and a transmission sleeve (21). The solar device comprises the power assembly, a photovoltaic panel (3), and a column (4).[French]
L'invention concerne un manchon antijeu hélicoïdal (1), un ensemble d'alimentation (2) et un dispositif solaire. Le manchon antijeu hélicoïdal comprend un premier manchon (11) et un second manchon (12), et une première hélice (111) est disposée sur la surface périphérique externe du premier manchon; le second manchon et le premier manchon sont agencés de manière coaxiale, une seconde hélice (121) est disposée sur la surface périphérique externe du second manchon, et le pas de la première hélice est égal au pas de la seconde hélice; le manchon antijeu hélicoïdal comprend en outre un élément élastique (13), une partie de liaison (16) et au moins un élément de limitation (14), l'élément de limitation étant utilisé pour limiter la distance maximale entre le premier manchon et le second manchon; l'élément élastique est utilisé pour ajuster la distance entre le premier manchon et le second manchon; et la partie de liaison est utilisée pour être reliée à un élément d'entraînement externe. L'ensemble de puissance comprend le manchon antijeu hélicoïdal, un élément d'entraînement, un arbre (22) et un manchon de transmission (21). Le dispositif solaire comprend l'ensemble de puissance, un panneau photovoltaïque (3) et une colonne (4).[Chinese]
