摘要
A shaft-hub connection system (1) with angular play for the bidirectional transmission of driving torque, comprising a shaft (2), a hub (4) provided with a hole (5) inside which the shaft (2), and means (6) for connection with predefined angular play which are interposed between the hub (4) and said shaft (2). The connection means (6) comprise at least one functional assembly (7) which comprises a slot (8) in which a corresponding coupling element (9) is accommodated so that it can move and is adapted to assume alternately a first position, in which it is retracted within the slot (8), a second position, in which it protrudes partially with respect to it along a first orientation, and a third position, in which it protrudes partially with respect to it along a second orientation, elastic compression means (10) interposed between the slot (8) and the coupling element (9) for the movement of the element from the first position to the second or third position, a first seat and a second seat (11, 12) for the abutment of the coupling element (9), respectively in the second and third positions which are associated inside the hole (5) of the hub (4) and are angularly offset about the main axis (A). In the first position the coupling element (9) is completely accommodated within the slot (8) in order to maintain the configuration for free relative rotation, while in the second or third position the coupling element (9) protrudes partially from the slot in order to engage respectively the first seat (11) in the first active configuration or in the second seat (12) in the second active configuration.
