Abstract
A swivelling handle includes three reduction gear assemblies, each assuring the control of movement about the three axes of rotation. Each reduction gear assembly has a first reduction stage and a second reduction stage with coaxial drive. This arrangement makes possible great compactness. The third motor can be placed transversally, essentially in the axis of the second reduction unit. Thus a swivelling handle is obtained with three axes of rotation, with full electrical controls, in which the movements of rotation are created by three independent electric motors corresponding to each of the three axes of rotation. The unit is especially compact and adaptable to any type of industrial robot.
