US Patent 9644704 Vibration safe motor fixation in an actuator

An actuator (10) has a casing (12) and an output (16). An electric motor (20) is disposed in a compartment (18) of the casing (12). The output (16) is driven by the motor (20) through a gear train disposed within the casing (12). The gear train includes a worm (30) on a shaft (22) of the motor (20) and a worm wheel (32) meshed with the worm (30). A mounting clip (40) is arranged to resiliently press the motor (20) into the compartment 18). The mounting clip (40) has fingers (44) which engage axial ends of the motor (20) to support the motor (20) against axial movement and separation due to axial loading and/or external vibrations acting on the actuator (10).
