Abstract
A brake (10) for a servo-motor (96) includes a housing (28) having first and second housing portions (30, 32) and in which an input (12) is rotatably mounted by a bearing (60). The pilot (98) of the servo-motor (96) is received in an enlarged recess (40) while the shaft (21) passes through an axial opening (38) and is secured in an axial bore (20) of the input (12) by a coupling (106) to align the brake (10) with the servo-motor (96). The brake (10) is secured to the servo-motor (96) by screws (108) which extend through elongated, radially elongated slots (46). A wedge shaped friction facing (82) is biased to engage an interface surface (26) of the input (12) and a friction surface portion (70) of the housing (28) by a spring (94) extending between a radial surface (92) and the first housing portion (30). The friction facing (82) is moved to a disengaged position by a piston (100) slideable under fluid pressure in a chamber (62) of the second housing portion (32).
