ROTATIONAL CONTROL APPARATUS

摘要

TITLE Rotational Control Apparatus A rotational control apparatus is shown in its most preferred form as a clutch-brake including an improved housing having a cylindrical body portion and first and second housing ends removably secured thereto. The body portion includes an axially extending annular member intersecting with a radially extending annular member. The radially extending annular member forms an interface surface and a surface for reciprocal receipt of a piston inside the axially extending annular member and forms a mounting flange outside the axially extending annular member for securing axially extending bolts threadably received in the second housing end. The first housing end includes an axially extending projection having surfaces for receipt in the axially extending annular member and for reciprocal receipt of the piston. The clutch-brake in a preferred form further includes an improved friction interface disc including a stamped flat ring portion secured to a second flat ring portion of a cast friction interface element in a spaced condition to form spaced cutouts for heat ventilation. The improved friction interface disc allows easy and inexpensive cast components eliminating casting cores for heat ventilation access between the interface surfaces of the interface disc.
