1. A drivetrain assembly for a personal care device, the drivetrain assembly comprising:
a shaft;
a frame comprising an exterior surface at a distal end of the frame, the exterior surface having an opening through which the shaft extends;
an abutment exterior to the frame and coupled to the shaft, wherein the abutment includes an engagement surface facing the exterior surface of the frame through which the shaft extends and the abutment is configured to engage with the exterior surface of the frame such that relative movement between the frame and the shaft in a given direction is inhibited past a threshold distance;
wherein the abutment is arranged on the shaft relative to the exterior surface of the frame so as to provide an airgap between the engagement surface of the abutment and the exterior surface of the frame, and the airgap corresponds to the threshold distance allowing the shaft to move in the given direction by the threshold distance to close the airgap;
wherein the abutment is a collar including a main body with an inner diameter corresponding to the diameter of the shaft and an outer diameter corresponding to the width of the opening of the exterior surface of the frame, and an engagement portion configured to project from the main body and to provide the engagement surface of the abutment; and
wherein the opening of the exterior surface of the frame is configured to receive the main body of the collar.
