Shock-absorption buffer shaft and application

Abstract

The invention relates to a shock-absorption buffer shaft. The shock-absorption buffer shaft comprises an input shaft, an input end cover, a force transfer pin, an input toothed sleeve, an input toothed wheel, a double toothed wheel, a spring, an output toothed sleeve, an output toothed wheel, an output shaft, an output end cover, a limiting bolt, a fastening bolt and an external sleeve. Force is transferred to the input toothed sleeve by virtue of the teeth of the first internal toothed ring of the input toothed sleeve in a manner of compressing a spring through the teeth of an external toothed ring on the input toothed wheel, later the force is transferred to the double toothed wheel by virtue of the teeth of the first external toothed ring of the double toothed wheel in a manner of compressing the spring through the teeth of the second internal toothed ring of the input toothed sleeve, then the force is transferred to the output toothed sleeve by virtue of the teeth of the first internal toothed ring of the output toothed ring in a manner of compressing the spring through the teeth of the second external toothed ring of the double toothed wheel, and then the force is transferred to the output toothed wheel by virtue of the teeth of the external toothed ring of the output toothed wheel in a manner of compressing the spring through the teeth of the second internal toothed ring of the output toothed sleeve, and finally, the output toothed wheel is used for transmitting the torque by virtue of the force transfer pin through the output shaft.

Description

technical field [0001] The invention relates to a shaft structure, in particular to a shock-absorbing buffer shaft. Background technique [0002] No matter in the transmission system of any mechanical equipment, the impact peak load during frequent starting and braking and sudden load changes will lead to component failure and accumulated fatigue damage. The output vibration frequency of the prime mover can also cause resonance due to the coupling of the load frequency, resulting in Parts break and fail, causing accidents. In order to reduce vibration and shock resistance, in the background of the existing technology, there have been plum blossom couplings, diaphragm couplings, star couplings, tire couplings, flange finger couplings, Snake type spring coupling, splint spring coupling, flange groove type finger pin coupling. Combining the various couplings mentioned above, their function is to reduce the impact and protect the shaft system with different material properties...

AI Technical Summary

Problems solved by technology

Combining the various couplings mentioned above, their function is to reduce the impact and protect the shaft system with different material properties at the peak time. However, due to the small rotation angle difference of the shaft, the energy-absorbing material absorbs less impact energy, and the impact energy is prolonged over time. Frequent load changes lead to wear and looseness, resulting in secondary impacts, not to mention bidirectional effects of vibration reduction, shock resistance, and smooth torque output
