Abstract


Precession reducer is a new gear box, but as its key components cycloid bevel gear manufacturing difficulties , become widely used of the main factors restricting the precession reducer . Domestic and foreign research has focused on the precession drive bevel gear tooth profile geometry and processing method . This paper studies the cycloid bevel gear meshing characteristics , and propose a new processing method , the processing device . Discusses precession meshing theory based on the mathematical model of the cycloid bevel gear meshing calculated to derive the the space sphere toothed equation for a more intuitive research toothed geometry obtained by the coordinate transformation method sectional a toothed equation , and analysis of multi- cycloid bevel gear teeth meshing . In accordance with the principle of kinematics of the cycloid bevel gear processing device , a new range of processing methods space agencies . According to the processing means to determine the trajectory of the tool is deduced the tool taper family envelope surface equation and the tool taper family envelope surface in the projection method sectional equation . With computer drawn out by the tool envelope toothed Figure . Engagement according to the established mathematical model , in MATLAB system platform , the preparation of the M-file , drawing toothed figure on the normal section , and further research on this basis, the number of teeth of the processing device , nutation angle , roller nose cone angle and the cone angle of the conical teeth meshing parameters on the tooth profile shape affect the extent and bias. Institutions diagram based on the cycloid bevel gear processing device , using ProE WildFire 2.0 profiling leverage this processing device for three-dimensional simulation , and the use of finite element analysis software ANSYS it is processing the force , deformation trend analysis . And processing device stiffness of the gear error . The deformation of the case , and the introduction of a finite element analysis to compare the difference between the actual tooth and the theoretical tooth .
