Abstract:

In order to manufacture the curvic coupling on a homemade CNC spiral bevel gear cutting or grinding machine, the manufacturing method for fixed curvic coupling was investigated. The cutting principle and cutting method of fixed curvic coupling was analyzed. According to the calculation cards of fixed curvic coupling, the method for determining cutter radius, blade point width, pressure angle of cutter blade and cutter profile radius were put forward. Based on the cutting principle and the configuration of CNC spiral bevel gear grinding machine, a method for determining the machine setting parameters was built and the calculation formulae was provided. Software for calculating the geometrical parameters and machine setting parameters for fixed curvic coupling was developed. According to calculation results of the software, a fixed curvic coupling was machined on H350G CNC spiral bevel gear grinding machine. The method for calculating the machine setting parameters was validated by the inspection of practical contact pattern and geometrical parameters.

Key words: curvic coupling, cutting principle, manufacturing method, machine setting parameter
