A brake is disclosed for the end of a shaft such as a motor shaft including a bowl-shaped housing secured to a bowl-shaped cylinder and sandwiching a pressure plate therebetween. A torque plate is reciprocally mounted and rotatably related to the housing by dowel pins which are reciprocally received in sleeve bearings and is biased by springs sandwiched between the torque plate and the housing and retained on spring pins. The torque plate includes circumferentially spaced integral lugs which extend through openings formed in the pressure plate and abut with a push plate of a reciprocal piston. A drive disc which is rotatably related but axially movable relative to the shaft to be braked is located radially inwardly of the lugs and is sandwiched between the torque plate and the pressure plate. The piston is also bowl-shaped and includes a circular plate terminating in an axially extending flange which is reciprocally received in an axially extending flange of the cylinder to define a pressure chamber. The housing and cylinder are closed to seal the internal components of the brake to allow ease of cleaning and to allow its use in food environments and in gas environments.

Brake for the end of a shaft such as the shaft of an electric motor comprising, in combination: a generally bowl-shaped housing including a radially extending annular flange terminating in an axially extending annular flange; a torque plate; means extending between the radially extending annular flange and the torque plate for reciprocally mounting and rotatably relating the torque plate relative to the housing; a drive disc rotatably related to the shaft; means located on the opposite side of the drive disc than the torque plate and secured to the axially extending annular flange of the housing for moving the torque plate away from the drive disc, with the means for moving the torque plate away from the drive disc including an axially movable piston, and lugs integrally formed on the torque plate for abutting with the piston, with the lugs extending from the torque plate located radially outwardly of the drive disc; and means for moving the torque plate towards the drive disc.
