Problems solved by technology
[0002] When the engine is tested on the test bench, due to the frequent and rapid changes of torque and speed, the torsional vibration problem is more significant, and when the torsional vibration of the engine causes the test bench to resonate, it will cause the dynamometer drive shaft or engine crankshaft to break
In order to avoid the occurrence of the above-mentioned incidents, the relevant technologies generally adopt the coupling of the transmission shaft to be arranged at the engine end, but because the elastic body of the coupling is made of rubber, there are many defects in oil resistance, temperature resistance and aging, etc., during use It is easy to produce deformation and rubber tearing, which will reduce the vibration damping effect and bring high research and development costs to research and development
