Abstract
A brake mechanism for selectively stopping and permitting rotation of a shaft journaled in a motor frame, the brake mechanism comprising: a brake hub secured to the shaft for rotation therewith, the hub including a plurality of first splines each having a first width in the circumferential direction of the hub and at least one second spline having a second width in the circumferential direction of the hub and greater than the first width, and a friction disk surrounding the hub for rotation therewith, the friction disk including a pair of opposed friction surfaces and having therein an aperture extending between the friction surfaces for receiving the hub, the aperture including spline recesses for receiving the hub splines and disk splines which mate with the hub splines and which provide for rotation of the friction disk with the hub; and brake disk engagement structure mounted for movement toward and away from the friction disk. Also, a brake disk assembly adapted to be mounted on a shaft journaled in a motor frame. Also, a friction disk adapted to be supported on a brake disk hub of a power transmission brake mechanism.
