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 cutting element which can be moved back and forth by a single-phase synchronous motor, the movement transmission being effected from the shaft of the motor to the cutting element by means of cams, which are in constant contact are held (EP-OS 45 107, Fig. 4).
the cam consists of two individual 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. In order 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 motor circulation can be stabilized by the use of elastic material in the transmission path between the cam and roller so that the running instabilities disappear and the operation becomes quiet and pleasant.
the shaving result improves.
the elastic material is a layer on the surface of the transfer roller and / or cam is arranged.
This elastic layer can be a rubber layer, which for example has a thickness of 1 mm and is applied to the surface of the transfer roller and / or cam.
the drawing shows a mounting wall 1 of a dry shaver to which a synchronous motor 3 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.
roller 13 cooperates 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 reciprocating bottom knife 29 of a vibration razor, which is guided in bearings 31.
a rubber layer 37 which is approximately 1 mm thick, can be arranged on the surface 35 of the roller 13. 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 use the whole cam as well to form whole roll of rubber or an elastic material.
