Embodiment Construction
[0014] Such as Figure 1-2 The inner winding device of a rotary mechanism shown includes a fixed system and a rotary system connected by a toothed bearing 2 and a flat cable 4; the fixed system includes a base 1, an inner winding drum 11, an outer winding drum 9, a fixed The pulley 6 and the cable pressing plate 10, the inner ring 2b of the toothed bearing 2 are fixedly connected with the base 1, the base 1 is integrated with the inner winding drum 11, and the inner winding drum 11 is located in the center of the base 1, and the outer winding drum 9 Sleeved on the outer circumference of the inner winding drum 11, and fixed on the base 1 by screws, the fixed pulley 6 is fixed on the base 1, and a pressure plate groove is opened on the inner winding drum 11 at the corresponding position in the same direction as the fixed pulley 6, and the pressure plate groove A cable clamping plate 10 is mounted on the inner via screws to form the input end 4a of the flat cable 4, and a gap cor...

The invention discloses an inner coiling apparatus of a swing mechanism in the signal transmission field. The apparatus comprises a fixing system and a swing system which are connected through a bearing and a flat cable. According to the invention, the swing system rotates about the fixing system so that a corresponding movable pulley group rotates when a movement thread clamp device in the swing system rotates. At the same time, the flat cable which is wound around the pulley group carries out corresponding rotation along the movable pulley group so as to guarantee tensity of the flat cable on the movable pulley group. Therefore, when the swing system rotates positively and negatively at any positions in a 0-360 degrees scope, the flat cable can be sticked on an inner coiling drum, the movable pulley group and an outer coiling drum so that a phenomenon that the cable is folded when it is too loose or the cable is snapped when it is too tight is avoided. The structure of the apparatus is simple. Manufacturing cost is reduced and simultaneously operation is reliable. Stability of cable signal transmission is guaranteed. The apparatus can be used for a radar antenna pedestal of 0-360 degree rotation and some swing mechanisms with small and medium-sized power.
Description
technical field [0001] The invention relates to a signal transmission device, in particular to a wire winding device. Background technique [0002] Slip rings are widely required in the fields of aerospace, aviation, navigation, and various precision instruments. Slip rings are used to realize the transmission of electrical power or electrical signals between two relatively rotating parts, so as to avoid twisting and breaking the wires during relative rotation. , the feature of the slip ring is that there can be multiple current channels on one circumference, and the cable will not be twisted due to the 360° rotation of the rotor fixed with it. Now the slip ring has been widely used, especially in the rotating radar The slip ring is essential in the antenna system. Its disadvantage is that in the long-term use process, there will be "excessive wear" or "increased contact resistance" failures, which will affect the use of the equipment, and it is not reliable. At the same ti...
