LINEAR ACTUATING ORGAN, IN PARTICULAR FOR THE REMOTE ACTUATION OF DISPLACEABLE COMPONENTS IN WIND TUNNEL MODELS

摘要

The invention relates to a linear actuating organ (1), in particular for the remote actuation of displaceable components in wind tunnel models. Said organ comprises a housing (2) and a geared motor (13) for driving a threaded spindle (27), the latter (27) having a threaded nut (28) that displaces a drive rod (11). According to the invention, the threaded spindle (27) is connected to the geared motor (13) by means of a chain drive (14), the threaded spindle (27) and a geared motor axis (49) being antiparallel in relation to one another. As a result of the antiparallel arrangement of the geared motor axis (49) and the threaded spindle (27), the linear actuating organ (1) has a compact construction. The linear actuating organ (1) is thus suitable for the remote actuation of displaceable components in wind tunnel models with small dimensions. In addition, the linear actuating organ (1) permits the generation of considerable mechanical actuating forces with a simultaneously high degree of positioning and repetitive accuracy.
