ABSTRACT:
There is provided a tooth system for the static transmission of a torque between two machine components coaxially disposed in one another, e.g. a shaft and a hub, in which the tooth surfaces are straight and are designed with a very large pressure angle and with large tip and root fillet radii. The pressure angle of one component deviating slightly from that of the other component by half the torsion angle so as to overcome backlash. As a result, under load, the tooth surfaces abut over their entire surface. Also, the hubs can be produced with a smaller blanking indentation, in particular in the case of discs made of sheet metal, which increases the bearing capacity, and furthermore this can be done even more precisely, which results in an increase in centering precision and less noise generation during operation.
