Abstract: A
free-form bevel gear machine has the potentialities to produce the
point-contact tooth surfaces of better performance more effectively than
a conventional cradle one. A point-contact tooth surface manufacturing
technology based on the generating theory of the free-form machine is
introduced. The basic equations and the formulae in detail for the
three-axis generating of the tooth surfaces are presented. The
generating motions are expressed as the functions of the work gear
rotary angle, which is taken as a motion parameter. The methods to
determine the motion functions and the other machine setting parameters
are explained. And lastly an example is given to demonstrate the
technology and the methods.
