Abstract: PROBLEM TO BE SOLVED: To materialize a load-displacement characteristic with small hysteresis in a laminated disc spring laminated in parallel.
SOLUTION: A plurality of disc springs 10 are laminated in parallel. The surface roughness of the contact surface of respective disc springs 10 is set within the range from Rmax 1.0 or more to 2.0 or less. A dissimilar material layer is provided between respective disc springs 10. When the surface roughness is within the range, the power loss by rubbing caused by the friction between the disc springs is reduced. When providing the dissimilar material layer between respective disc springs 10, the characteristic is not deteriorated even by long term use. Therefore, a load-displacement characteristic with small hysteresis is obtained over a long period of time.

Abstract: PROBLEM TO BE SOLVED: To obtain a load-diplacement characteristic with small hysteresis, in a heavy Belleville spring piled up in parallel. SOLUTION: A plurality of belleville springs 10 are piled up in parallel. The surface roughness of the mating surface of each Belleville spring 10 is within a range not less than Rmax 1.0 and not more than 2.0. A different material pile is prepared between each Belleville spring 10. If the surface roughness in this range, a loss of a force of the Belleville spring 10 dependent on rubbing can be made small. Moreover, if a different material pile is prepared between each Belleville spring 10, the characteristic is not deteriorated by the activity of a long time, either. By this, the load-displacement with characteristic small hysteresis can be obtained for a long period of time. COPYRIGHT: (C)2008,JPO&INPIT
