Document Type and Number:
WIPO Patent Application WO/2010/056533
Kind Code:
A3
Abstract:
A rotational coupling device (20) for use as a clutch and/or brake is provided having structure to compensate for wear on braking surfaces. The device includes an armature (36) coupled to an output member (24) and movable between positions of engagement with a rotor (26) and a brake plate (38). The brake plate is coupled to a stationary field shell (32) that houses a conductor (34) on one side of the rotor opposite the armature and brake plate. The brake plate is axially spaced from the field shell and a removable shim (42) or adjustable spacer (136) is disposed between the brake plate and the field shell. Removal of the shim or adjustment of the spacer permit movement of the brake plate towards the field shell to compensate for wear in the clutch and/or brake engagement surfaces of the device.
