Abstract
An electromagnetic brake wherein a first component is non-rotatably secured to a shaft or another rotary member and a second component of the brake is non-rotatably secured to a stationary part with freedom of movement in the axial direction of the first component. The second component contains a solenoid which is energizable to attract a friction generating liner of the second component against a disk of the first component and to thus arrest the first component. The width of the air gap between the first and second components can be adjusted by screws which extend radially of the first component or in parallelism with the axis of the first component and mesh with the stationary part. The conical or rounded tips of the screws can shift the second component toward the first component to reduce the width of the air gap. A polygonal array of leaf springs couples the second component to the stationary part and tends to move the second component axially of and away from the first component.
