Abstract
According to an aspect there is provided a drivetrain assembly (1) for a personal care device (10). The drivetrain assembly (1) comprising: a shaft (2); a frame (4) comprising an opening in a surface (4a) of the frame (4) through which the shaft (2) extends; and an abutment (3) provided in cooperation with the shaft (2). An engagement surface (3a) of the abutment (3) is configured to engage with the surface (4a) of the frame (4) such that relative movement between the frame (4) and the shaft (2) in a given direction (d) is inhibited past a threshold distance.
Claims15
A drivetrain assembly for a personal care device, the drivetrain assembly comprising:
- a shaft;
- a frame comprising an opening in a surface of the frame through which the shaft extends;
- and
- an abutment provided in cooperation with the shaft, wherein
- an engagement surface of the abutment is configured to engage with the surface of the frame such that relative movement between the frame and the shaft in a given direction is inhibited past a threshold distance.
A method of manufacturing a drivetrain assembly for a personal care device, the method comprising:
- resiliently mounting a shaft in a frame of the drivetrain assembly such that the shaft extends through an opening in a surface of the frame;
- placing an abutment in movable engagement with the shaft at a first position on the shaft such that an engagement surface of the abutment is in engagement with the surface of the frame;
- applying a predetermined force to the shaft in a given direction along a longitudinal axis of the shaft such that the shaft moves relative to the frame in the given direction and the abutment moves to a second position on the shaft due to engagement of the engagement surface of the abutment and the surface of the frame;
- releasing the predetermined force applied to the shaft such that the shaft moves relative to the frame in a direction opposite to the given direction and the abutment moves with the shaft such that the abutment remains at the second position on the shaft and the engagement surface of the abutment is no longer in engagement with the surface of the frame;
- and
- fixing the abutment to the shaft at the second position.
