AI Technical Summary
When faced with instantaneous impact loads, the support structure of traditional heavy-duty gearboxes transmits the impact loads to the core components with almost no attenuation, leading to fatigue damage to vulnerable parts and an inability to buffer continuous vibrations, posing a risk of resonance.
A variable stiffness impact-resistant support system is adopted, which uses a servo motor to drive the gear disk to rotate, adjusts the pre-compression of the damping spring and the damping force of the damper, and achieves adaptive stiffness adjustment. It also absorbs impact energy through a multi-stage energy consumption mechanism, including elastic deformation, damping fluid flow and lateral buffering.
It effectively dissipates impact energy, avoids wear and bearing failure caused by excessive displacement of the gearbox, ensures operational stability and service life, and achieves a dynamic balance of load-bearing and buffering effect.
