DEVICE FOR JOINING A MODULAR BLADE
The invention relates to a device for joining a modular blade, the joint being formed by a plurality of bolts (8) that are secured between inserts (3 and 4) housed in the composite material of two modules (1 and 2) to be joined. The device allows the bolt (8) to be preloaded with less application force and greater precision than known systems, also ensuring that the device is maintenance free. For this purpose, each device is formed by lateral caps (9), an upper wedge (10) and a lower wedge (11), and transverse screws (12), all of this surrounding the corresponding bolt (8) disposed inside of a hole between two blade modules (1 and 2). When a force F1 is applied to the wedges (10 and 11), the caps (9) respond with a force that separates the modules (1 and 2) and pre-stress the bolt (8).
