1. An electromagnetic brake assembly comprising:

  • A. a rotatable brake wheel fixed to a shaft which has the rotation thereof selectively braked by the brake assembly;

    B. a pressure ring nonrotatably mounted axially a given distance from said brake wheel during operational rotation of said shaft and adapted to axially move toward and away from the brake wheel;

    C. a brake armature mounted axially from said pressure ring and adapted to axially move in fixed relation with respect to said pressure ring during operational rotation of said shaft;

    D. at least one brake liner adapted to fricationally engage between the brake wheel and pressure ring when the pressure ring is moved axially toward the brake wheel;

    E. an electromagnetic means mounted axially from the brake armature for engaging the brake armature to move the pressure ring away from the brake wheel;

    F. biasing means for urging the brake armature and pressure ring toward the brake wheel to engage the brake liner between the brake wheel and pressure ring and brake the rotation of the brake wheel; and

    G. gap control means for adjusting the axial distance between the brake wheel and the pressure ring.
