Abstract
This invention is a magnetic clutch brake mechanism operable to achieve either a clutch or a brake function and can be installed, for example, on a lawn mower apparatus to selectively control the rotating movement of a lawn mower blade member. The magnetic clutch brake mechanism includes: (1) a main actuator assembly; (2) a drive rotor assembly which is connected to a main drive shaft for rotating same; (3) a clutch plate assembly operably connectable to the drive rotor assembly; and (4) in this case, a blade mount assembly to receive a rotatable lawn mower blade that is securely fastened thereto. The main actuator assembly includes an actuator bracket member which is connected to an actuator ring member that is selectively movable axially about the drive rotor assembly and the clutch plate assembly to alter a magnetic field therein. The drive rotor assembly includes a rotor member which is driven by a gasoline or electric motor in order to rotate same at a desired speed. The clutch plate assembly includes a plate member used to secure a plurality of magnet members against a collector member and haivng a bearing member which rotatably connects same about the main drive shaft. The blade mount assembly is connected to the clutch plate assembly and operable to receive a lawn mower blade member thereon by a plurality of nut and bolt members. The actuator ring member is operable to move axially about the clutch plate assembly to selectively affect the magnetic field therein to clutch or brake the relative rotating members.
