The established torsion pivot provides torque via several Belleville spring. The established structure with many issues includes the life cycle is not enough, have to use several springs to set up it, the Belleville spring with directional characteristic, and the tolerance of the torque is very wide, that can lead to the yield rate is very low, and the cost of production is high. These statuses are very annoying.
This research offers one kind of torsion pivot while utilizing MDU spring. In this study we can know MDU torsion pivot that life cycle is very long, consumption need only one, MDU spring non-directional characteristic can avoid and solve the problem that a Belleville spring produces because of directionality and bad lead, the range of becoming different of the torsion produced is very small at the time of production.
In addition, must with more than two sections torsion and must have with great first torsion, because compression actions of the iterance will damage Belleville spring, so it is difficult to make with a Belleville spring, but this is one of the advantages that MDU spring has.
Synthesize all the above results, MDU spring is enough to replace a Belleville spring on life cycle, include improve a lot of issue about spring assembled, include improve the questions that directionality produces, and avoid to produce big tolerance of the torque etc.
Apply to the torsion pivot, MDU spring has more excellent behavior than a Belleville spring. | en_US |
