Abstract: An expanding tool comprising: an actuator comprising a cylindrical housing that defines an actuator housing cavity; a primary ram disposed within the actuator housing cavity, the primary ram defining an internal primary ram cavity; a secondary ram disposed within the internal primary ram cavity; a cam roller carrier coupled to a distal end of the secondary ram; a drive collar positioned within a distal end of the actuator housing cavity; a roller clutch disposed within an internal cavity defined by an inner surface of the drive collar; a shuttle cam positioned between the roller clutch and a distal end of the primary ram; an expander cone coupled to the primary ram; and an expander head operably coupled to the drive collar. When triggered, the actuator first rotates the expander head and then the actuator expands the expander head.

Abstract: A method of cooling an electric motor configured for use in a power tool. The electric motor has a motor shaft rotatable about a motor axis. The power tool further includes a fan assembly attachable to the motor shaft and an energy storage device coupled to the motor shaft and to the fan assembly. The method includes activating the electric motor to supply torque to the motor shaft. The method further includes rotating the motor shaft and the fan assembly about the motor axis. The fan assembly generates an airflow to cool the electric motor. Moreover, the method includes supplying torque from the electric motor to the energy storage device and deactivating the electric motor to stall rotation of the motor shaft. The fan assembly continues to rotate about the motor axis to generate the airflow after rotation of the motor shaft has ceased.

Abstract: A power tool includes a motor having a motor shaft that rotates about a motor axis in a first rotational direction. The power tool also includes a fan assembly attachable to the motor shaft for rotation in the first rotational direction. The fan assembly includes a fan body and a bearing having a race that is rotatably affixed to the fan body. The race is freely rotatable relative to the motor shaft in the first rotational direction, and fixed against rotation relative to the motor shaft in a second rotational direction opposite the first rotational direction.

Abstract: A method of operating an expanding tool includes advancing a ram a first distance to rotate an expander head in a first rotational direction and advancing the ram a second distance so that the ram causes head segments of the expander head to expand radially.
