Abstract (en)

Safety drive unit, in particular for the movement of protection screens in manufacturing machines the said unit comprising at least one drive motor (25, 26) that drives a support of the motion (7) of an element of cover and/or protection (5, 205). According to the invention, the transmission between the drive motor (25, 26) and the protection screen (5, 205) is formed by a pair of helical gears (22, 23) engaged between each other with the corresponding external helical threads (122, 122', 123, 123'), the said helical gears (22, 23) being made in such a manner, that the rotation of the helical drive gear (23) in the two directions engages the rotation in the two directions of the other helical driven gear (22), whereas a rotation of the driven helical gear (22) engages a locking underpinning of the same in or with the helical drive gear (23) which prevents the rotation. The invention relates also to a protection screen equipped with such a drive unit. <IMAGE>
