Abstract
An actuator for a papermaking machine. The actuator is designed to function either as a slice lip or coatweight actuator or as a dilution actuator depending on the orientation of a cam disk in the actuator. The drive motor and position sensor in the actuator are in a side by side arrangement allowing for a single cover to enclose both the drive motor and the position sensor. The actuator has a manual adjustment which comes into engagement with the drive motor only when it is desired to manually adjust the actuator. The manual adjustment is designed so that it does not lock with the drive motor and requires only a moderate amount of force to be brought into engagement with the manual shaft. The actuator has a drive block connected to the speed reducer of the actuator. The drive block interfits with the cam disk in a manner to function as a spring loaded splined connection. This connection provides the necessary force to prevent rotary free play of the cam disk. The cam disk is free to rotate and move up and down in a motor plate. The position sensor is in contact with one side of the cam disk.
