Not only be used for transmitting torque at one with regard to the form fit element but also be used for favourable further scheme with regard to the multifunctional application of radial compensation axle dislocation, form fit element is configured to groove and another form fit element is configured to the tenon corresponding with described groove.Described groove and the described tenon that is embedded in described groove jointly are configured on the one hand torque is delivered to from driving shaft the linear guide that propeller boss on telophragma connects and be configured on the other hand the radially relative motion between driving shaft and telophragma.Described groove is the wedge groove when the swallow-tail form guider of village.This wedge groove has the shape of cross section of wedge shape, and this shape of cross section attenuates outwardly.Two inwalls or the sidewall of described wedge groove extend outwardly opposite to each other.
In another further scheme, described tenon and described groove are arranged on described the first coupler half one and described telophragma.Preferred said tenon is arranged in described the first coupler half one and described groove is arranged on described telophragma.
With regard to being connected by other linear guide, the second coupler half one in favourable further scheme, an other groove is set with regard to telophragma at one on described telophragma.Described other groove extends transverse to the groove of following linear guide, by this linear guide, telophragma is connected with the first coupler half one.
In an other further scheme, the first coupler half one is fixed on or is formed on driving shaft and the second coupler half one is fixed on or is formed on roller.They are configured to tenon or lath and are for example screwed when fixing corresponding coupler half.They are configured to groove or gap and for example are milled into when being shaped corresponding coupler half.
One with regard to described roller with regard to the glazing device of printing machine or the application in anilox inking unit in favourable further scheme, described roller is anilox roll.
Description of drawings
By draw in following description of a preferred embodiment and accompanying drawing on other structures and function on favourable further scheme.In accompanying drawing:
