Fail Safe Brake

Braking is applied to a shaft 1 by the engagement of a circular brake pad 2, secured to an armature plate 3, and a brake plate 4. Spring steel rings 5 welded into a unitary structure urge the pad 2 against brake plate 4.

A coil 6 is energizable to disengage the pad 2 and plate 4 against the action of the rings 5. One of the rings 5 is secured to the perimeter of armature plate 3 at diametrically opposed points, and the other ring 5 is similarly secured to the coil housing 7.
