Abstract
Abstract. In order to reduce the vibration of the double-sided
meshing nutation drive with double circular arc spiral bevel gears, the
dynamic modal of the nutation system is analyzed. The
bending-torsional-axial coupling nonlinear dynamic model of the double-sided
meshing nutation drive system with time-varying meshing stiffness, meshing
damping, transmission error and tooth backlash is established, and the
equation of motion of the system is derived. The natural frequencies and
corresponding modal modes of the nutation system are calculated, and the
effects of the average meshing stiffness of gears and the bearing support
stiffness of nutation gears on the modal of the system are analyzed. The
modal analysis of double circular arc spiral bevel gears is carried out, and
the ten order natural frequencies and their corresponding modes are
obtained. The results show that the nutation drive system and the double
circular arc spiral bevel gears do not resonate during transmission.
