Abstract

The invention discloses a cylindrical cam excitation driven bending-torsional coupling resonance type residual stress relieving device, and relates to a cylindrical cam transmission type alternated force moment bending-torsional coupling resonance type vibratory stress relief method. Torsional vibration output by a cylindrical cam transmission type alternated force moment torsional vibration exciter is applied to a high-rigidity rotary shaft, when the rotating frequency of the rotary shaft is equal to the difference of the natural bending frequency and the natural torsion frequency, based on the bending-torsional coupling resonance theory, namely, torsional vibration excitation with the frequency equal to the natural torsion frequency can excite bending resonance, meanwhile, the bending resonance and the torsional resonance are mutually strengthened, and enough dynamic stress is generated to eliminate the residual stress of the high-rigidity rotary shaft. According to the residual stress relieving device, the problem that bending-torsional coupling resonance vibratory stress relief is limited by a torsional vibration excitation source is solved, the residual stress of the high-rigidity rotary shaft is eliminated through cylindrical cam transmission type alternated force moment bending-torsional coupling resonance, the efficiency is improve, and the safety and reliability of production are improved.

Description

technical field [0001] The invention relates to a vibration aging device in the mechanical field, in particular to a bending-torsion coupling resonance type residual stress elimination device induced by cylindrical cam excitation. Background technique [0002] The dynamic stress generated by the bending-torsion coupling resonance is used to eliminate the residual stress of the shaft parts. In the implementation process, the torsional vibration excitation needs to be applied to the shaft. When the motor rotation frequency is equal to the difference between the bending natural frequency and the torsional natural frequency, when the applied torsional The vibration excitation is equal to the torsional natural frequency. According to the bending-torsion coupling theory, the eccentric shaft will simultaneously excite the bending resonance, and the bending resonance and torsional resonance will strengthen each other to generate sufficient dynamic stress. The torsional vibration exc...
