Safety system

摘要

This safety system includes:
a toothed wheel, connected rotationally with respect to at least one rotating member to be braked,a worm driven rotationally by a motor upon rotation of the rotating member and permanently in mesh with the toothed wheel,a housing forming:
a longitudinal wall located on the side of the worm diametrically opposed to the toothed wheel, and extending along the worm at a distance of the latter ranging between 0.001 and 0.01 times the diameter of the worm, anda first end wall integral with the longitudinal wall, located opposite a first longitudinal end of the worm; andenergy absorption/dissipation elements interposed between the first end wall and the first longitudinal end of the worm, the worm being slidingly mounted in the housing such that the first longitudinal end of the worm comes closer to the first end wall when the worm slides in the housing.

主权项

1. A safety system, configured to be fitted to a mechanism with one or more rotating members, the safety system comprising:
a toothed wheel, connected rotationally with respect to at least one rotating member to be braked; a worm having a diameter, driven rotationally by a motor upon the rotation of the one or more rotating members and permanently in mesh with the toothed wheel; a housing forming
a longitudinal wall located on the side of the worm diametrically opposed to the toothed wheel, said longitudinal wall extending along the worm at a distance of the worm comprised between 0.001 and 0.01 times the diameter of the worm, anda first end wall integral with said longitudinal wall, located opposite a first longitudinal end of the worm; and first energy absorption/dissipation means interposed between said first end wall and said first longitudinal end of the worm, said worm being slidingly mounted in said housing such that said first longitudinal end of the worm comes closer to said first end wall when said worm slides in said housing.
