Definitions
- the invention relates to a drive device for a dry shaving apparatus with a shaving foil and a cutting element which can be moved back and forth relative to the shaving foil by means of a single-phase synchronous motor, the movement transmission being effected from the shaft of the motor to the cutting element by means of cams and transmission rollers which are kept in constant contact are and of which a role is elastic (EP-A1-45107, Fig. 4).
- the cam consists of two single cams arranged at right angles to each other, each of which is scanned by means of its own transfer roller. Both roles are rigidly connected. To avoid jamming and to achieve tolerance compensation, both rollers are designed to be somewhat elastic on their circumference.
- Driving a shaving device with the aid of a single-phase synchronous motor has advantages with regard to the device dimensions.
- a concentric motor works more smoothly than an oscillating armature motor.
- the object is achieved in that when using a single transfer roller that is pressed against a single cam, at least the surface of the transfer roller and / or the cam consists of elastic material, the elastic material as a layer on the surface of cams or Surface of the roll is arranged and wherein the elastic layer is about 1 mm thick.
- the motor circulation can be stabilized by the use of elastic material in the transmission path between the cam and the roller so that the running instabilities disappear and the operation becomes quiet and pleasant.
- the shaving result improves.
- the drawing shows an assembly wall 1 of a dry shaver to which a synchronous motor is attached.
- the drive shaft 5 of the synchronous motor protrudes vertically from it and points upwards out of the plane of the drawing.
- a cam 7 is arranged on the drive shaft 5 and is covered on its transmission surface 9 with an approximately 1 mm thick rubber layer 11.
- a roller 13 interacts with the cam and is held in a bearing bracket 15.
- the bearing bracket 15 can pivot about an axis 17.
- a spring 21 presses against the bracket 15, the pretension of which can be adjusted with the aid of an adjusting screw 23.
- the transmission lever 15 is connected via a driver .27 to an alternating back and forth knife 29 of a vibrating razor, which is guided in bearings 31.
- a joint not described in more detail, for example a film joint 33, cancels the rigid connection between the cutting element 29 and the driver 27.
- a rubber layer 37 can be arranged on the surface 35 of the roller 13, which is approximately 1 mm thick. This rubber layer 37 can take the place of the rubber layer 11 on the cam 7. But it is also possible to let both rubber layers work together. It is equally possible to form both the entire cam and the entire roller from rubber or an elastic material.
